For this set of wide-ranging user needs, the scientists' analytical demands were not adequately satisfied in the versions of the tools used in the study, and only three of the 13 scientists continued to the Beyond Read-offs stage for deeper insights. The three scientists who engaged in Beyond Read-offs did not get very far in this stage. Thus results in this section depend more on interview responses than in previous sections. During interviews the scientists discussed insights they would like to have gained in the Beyond Read-offs stage, framed as questions and covering the following relationships:.

Conceptually and technologically, this reasoning required more immersion into biological uncertainty and incomplete knowledge than analysis so far had involved, and it required more deliberate inferential reasoning. Inferences included the use of multiple strategies and reasoning across scales. To draw inferences, scientists sought cues about localized biological events — conditions, contexts, and interactions that potentially influenced biological functional behaviors, changes, and self-regulation.

For example, the scientists coupled analysis of protein interactions and pathway networks to see if this cross referencing might suggest mediating groups of genes for a given disease. For these questions, the scientists went beyond read offs and, in doing so, expected to interact with the data with a great deal of user control. The scientists became stymied when interface displays did not afford adequate interactivity. Notably, multiple attributes pertaining to a gene were formatted as concatenated strings, and some fields themselves were defined as a compilation of many values — e.

For Beyond Read-off purposes, however, this data structuring obstructed the scientists from grouping and selecting items based on single attributes and from seeing just the selected items displayed and highlighted in the network view. Nor could the scientists color code or aggregate by individual not stringed field values.

Additionally, with this version of Cytoscape and with plugs ins other than MiMI available at the time, the scientists could not selectively extract sub-networks by trait e. As one of the three scientists participating in Beyond Read-offs commented in think-alouds:. These genes are involved in multiple concepts. Now I need to look at them biologically and single out just this one annotation. Is this concept up in the context of a cell that is "just resting" but down in a cell that is proliferative?

Causal inferences, moreover, had to be warranted and defensible. The scientists who engaged in Beyond Read-offs looked once more for statistical evidence that network structures had potential biological meaning and were not simply chance occurrences. For example, when the scientists used SAGA within MiMI-Cytoscape to match potentially meaningful sub-graphs embedded in the whole to canonical pathways, they wanted to know how confident they should be in the match, given the accuracy of the underlying similarity matching algorithm. The scientists also wanted to link to and revisit literature about relationships of interest to read details that would help in judging credibility.

Some of these overlapped with transition stage needs:. Unfortunately, with these versions of the tools, none of the scientists found enough of what they were looking for, and none was able yet to gain deep insights for building hypothetical stories. Results show many common patterns across cases in scientists' ways of knowing and reasoning but suggest, as well, that creating a match between a tool and a scientist's cognition might be specific to a scientist's domain specialization and analytical objectives.

The biostatistician, for example, as a statistics specialist distinctively cut short even her surface level insights for want of hard test statistics. The biomedical researcher, whose prime analytical objective during the Separating the Wheat from Chaff stage was to quickly hone in on relevant and previously unknown literature about her target gene family, also encountered impasses but in her case because of her distinct analytical objectives. In the rest of the field cases, results show that MiMI and MiMi-Cytoscape, which are emblematic of other bioinformatics tools, have advanced to enabling scientists to access and understand rich stores of heterogeneous data.

The scientists were able to make critical judgments and learn new things from the data. Moreover, these tools made major steps in providing surrogates for test statistics to help scientists achieve confidence. These advances have opened the realm of systems biology to countless everyday scientists in biomedicine.

But results also suggest that in making these tasks accessible the tools sparked scientists' motivations to go beyond read-offs. As results reveal, designs beyond read-offs have to differ in kind not just degree from designs for straightforward data extraction for affirmations or classifications. Admittedly, analytical integration for hypothesizing is a long exploratory process, and it may not be surprising or troubling that scientists did not achieve a well-developed hypothesis at the close of the observation periods.

But findings from this study — and from others — suggest that tools today are not sufficiently launching scientists on this long term hypothesizing process to begin with. This whole process requires integrating classification, mental modelling and narrative reasoning — that is, facilitating the move from lists to stories. Whether bioinformatics developers strive to build one tool or many to fulfil this purpose, the goal must be to support scientists in integrating complementary modes of reasoning and in interweaving "loose" and "strict" analyses for explanatory inquiries under uncertainty.

Supporting only one mode of reasoning isolated from the rest — regardless of which mode it is — or insufficiently supporting transitions between them impedes the formulation of hypotheses. One thing that is clear from the results in the Transition and Beyond Read-off stages is that "information delivery" is not enough to satisfactorily support this analytical flow and integration.

In the field study, a good deal of the data relevant to scientists' transitional thinking and causal mental modelling was available "deliverable" from the tools but was often hard to find or time-consuming to encode into graphics. Equally if not more important, available data were not represented as scientists needed them to be for the intellectual processes of mentally modelling causes and outcomes.

For example, the data were not represented in ways that conveyed or cued biological meaning and credibility. Moreover, for the manipulations of data that are prerequisite to constructing knowledge during causal mental modelling, the data often were not structured right, for example for users to cluster, filter, color code, and lay out graphs. As researchers in visual analytics show, different types of analysis tasks demand specific visual representations of knowledge. For example, users benefit most from side-by-side views — such as the network and tabular views in MiMI-Cytoscape — when their tasks involve detecting patterns of interest and making transitions to new modes of reasoning.

But they need single views rich in relevant information and conceptual associations when their goal is to understand causal relationships and diagnose problems [ 33 ]. Conceiving and then designing these rich views are vital but challenging. The scientists in the study did not engage seriously in narrative reasoning but research suggests that support for story building also differs dramatically from support for classification reasoning and read-offs.

For example, they may associate and synthesize their cumulatively generated knowledge to tell an hypothesized story about two potentially influential proteins in a localized context — the star actors and scene in the story. The story would capture how the proteins are encoded by genes that lie on separate disease-relevant chromosomes, how they function in a disease-related intracellular signaling pathway, and how evidence suggests a genetic variant that may cause one of the proteins to vary in structure, activation, and localization, thereby affecting variation in the other protein in disease susceptibility.

Noting the challenge of supporting this mode of synthesizing knowledge into convincing stories Kumar et al. Similarly, research shows that overly-formalized narrative objects and their properties do not effectively support narrative reasoning [ 27 ]. My field study results show that for the explorations scientists conduct in explanatory systems biology analyses, tool designs and scientists' cognition are mismatched in the following three ways:. Confidence in the data, tools, and one's own interpretations of knowledge representations was fundamental to scientists' willingness to engage in and continue engaging in systems biology analysis.

Validations occurred from the start during Confirmation and continued throughout the analysis. For Confirmation and Separating the Wheat from Chaff the scientists needed the following data and interactions for their validations: Surrogates for test statistics, such as provenance; counts of interactors, articles, and experiment types associated with an interaction; easy sorting of table fields to locate expected results; and explanations of tool algorithms for processing and integrating data.

These features and content were largely present but, at times, were incomplete. Resolving the incompleteness and thus the mismatches for these earlier stages of analysis is not particularly difficult to achieve technologically. Doing so would be a low cost way to enhance scientists' trust early on and possibly instil more tolerance for uncertainty later. It could be that the more confidence scientists gain early on, the more "forgiving" of the tool and data they will be later when dealing with the unavoidable incompleteness and uncertainty of contextualizing biological relationships. Results show that in later stages ambiguous concepts such as interaction, pathway, and molecule type became increasingly important to scientists' analysis and validation of potentially meaningful relationships.

Similarly, the scientists increasingly demanded statistical evidence, evidence that often is not easy to mine and provide technologically or that may be non-existent. The field study suggests that part of these complications to validation and consequent mismatches may be allayed if tools give scientists easy means for bringing in their own data and statistics so that they can integrate and analytically manipulate these data with their query results. The development of more statistical models or presentation of test statistics in which scientists can believe is also needed to reduce tool mismatches with validation needs and practices and to help scientists build confidence.

The importance of helping scientists make the transition from classification to model-based reasoning cannot be overemphasized. Given the high rate of attrition at this stage in the field study, it is clear that support in tools for this transition is as important as facilitating each of the stages itself. During this transition, scientists made judgments about the value of the displayed knowledge representations for their intended inferential purposes.

The scientists were not as concerned as earlier about the literal content of the data. Rather knowledge representations and their value to an analysis required data to be structured in ways that allowed the manipulations the scientists sought to perform to find causal relationships.

The scientists needed to see that they could manipulate views by interacting with a single value for an attribute, such as a non-stringed value for molecular function, pathway, or biological process. The scientists also needed to inter-relate select sets of attributes to draw inferences about possible chains of events and effects.

Moreover, the scientists needed some indication that they would be able to negotiate the meanings of ambiguous concepts relevant to relationships of interest vital to explanatory inferences, such as interaction type. Finally, they needed knowledge representations that cued them about the connections constituting a protein cluster, the purported strength of the connections, the biological implications, and statistical warrants for the clusters.

It was also during the Transition that the scientists checked to see if the tools adequately provided means for interacting with and transforming data in scientists' intended ways. Mismatches between tools and the cognitive transitions scientists made in the move from lists to explanations may be reduced if views of data and relationships more deliberately direct scientists' attention selectively — for example, to good biologically meaningful entry points in complex network associations.

The problem is not rich displays of networks and data per se. If presentations provide wrong or incomplete information or insufficiently emphasize relationships relevant to explanations ttention to only surface level data, analytical performance and accuracy for a higher order tasks suffer [ 34 , 35 ]. For networks, this relevance requirement means drawing a user's eye to the high dimensional relationships through color, layout, and groupings.

Additionally, mismatches for scientists' transitions to causal modelling may be diminished if tools provide better cues about conceptual relationships. Choices of layouts can provide such cues, with research in visual cognition showing that when the same connections between nodes are spaced dissimilarly users judge different relationships to be important [ 36 ]. Overall, building domain knowledge about relationships into designs- not delivering data elements per se — is crucial for overcoming transition-related mismatches. For causal mental modelling, the conceptual relationships that the scientists sought were fluid, dynamic, and not fully formalizable.

To uncover them through inference, the scientists expected to rearrange and transform relationships and to view the same data from many perspectives and levels of abstraction. They expected to differentiate normal from abnormal biological behaviors and inferentially distinguish causes from catalysts. In the process, they expected to be able to freely and easily change views of data relationships.

Mismatches occurred between expectations and tool support because representations that afforded classification earlier were now insufficient. Moreover, interactivity for data manipulation was not attuned to the explorations required for inference amid ambiguity, incomplete knowledge, and multiple scales. The necessity of this interactivity cannot be overemphasized. User controlled interactivity served as important a function in being able to produce new knowledge and gain deep insights as content.

For example, scientists expected to be able to recursively re-assemble relationships and potential causal associations spatial transformations in order to infer possible temporal events. Structuring layouts by regulatory relationships organized by biological region would signal interactions over time and space. Some scientists also spoke of wanting to transform workspaces and data relationships into views of overlaid networks — those of interacting gene products, canonical pathways, and diseases associated with pathways.

These presentations would have evoked biological situational awareness. Scientists knew they could not see actual representations of the dynamics and variability of the genomic and molecular biosystems they sought to analyze. They needed cues from the data and views to infer multi-dimensional chains or loops of actions and outcomes. They wanted certain content to be perceptually highlighted and wanted cues from layouts and groupings about potential biological meanings inherent in visible network configurations.

Additionally, side by side graphics e. Other bioinformatics studies have similarly articulated this need for tools to "go beyond simplistic graphical models and mere compliance with accepted standards to provide many different types of network views, each at a different level of abstraction" because relationships among proteins, interaction partners, and interaction types often differ based on a cell state or location [32, ]. Specifically, researchers have called for more pathway information, overlays and relationships between molecular interactions and pathways, views of regulatory relationships within pathway contexts, and molecular interactions in relation to many interconnected pathways at once [ 28 , 29 ].

Researchers also have argued that tools need to provide aggregates and details of the same elements, interactivity for selectively expanding neighbors of specified proteins, capabilities for users to specify semantic substrates for layouts, and sub-graphs of network motifs tied to biological concepts [ 10 , 29 ]. Results from the field study corroborate the centrality of these design issues and now show the direct connection between them and scientists' core processes of explanatory reasoning. Field study results also underscore the need to couple these views with adequate interactivity for data and view manipulation and with support for scientists' continuously interleaved validation processes.

Without addressing such design improvements, mismatches are likely to continue. In the current bioinformatics research literature, models of scientists' flows of analysis for systems biology explorations are incomplete. For design purposes, more comprehensive, empirical models of scientists' higher order cognition are prerequisites for creating tools that effectively and usefully match biomedical researchers' actual ways of knowing and reasoning. In this field study, as in other bioinformatics usability research, scientists could successfully pose and answer "What?

What hidden relationships innovatively mined from the literature show unexpected biological relationships? But the scientists — and biomedical researchers in general today — could not adequately achieve new explanatory insights into the how's and why's of biological associations and outcomes within and across biological regions. Given scientists' shared stages of analysis, their multiple complementary modes of reasoning, and their interplay of loose and strict analysis, it is clear why scientists in this study — as in other studies — more easily gained surface level insights than deep insights.

Tools strongly support surface level insights by categorizing and organizing data displays in ways that resonate with scientists' approaches to classifying data and judging relationships to be broadly interesting or not. By and large, scientists could perform these tasks through read-offs, and outcomes were motivating.

Yet once scientists gained surface insights, they wanted to do more. They wanted to construct credible hypotheses. Findings show that to facilitate deep insights and hypothesizing bioinformatics tools must do a better job of matching scientists' needs and practices. They have to better match scientists' processes for validating throughout analysis, their transition from classification to explanatory mental modelling, and their processes of mental modelling across scales and amid uncertainty. For design purposes, the field study results reveal the important role that technologies for systems biology analysis play in scientists' exploratory cognition.

Because tools are the prime workspaces in which biomedical researchers view and interact with representations of knowledge to further construct and transform knowledge for hypothesizing purposes, technologies shape the course and completeness of this analysis. To varying extents and with qualitative consequences, tools shape scientists' intentions and opportunities for causally exploring known and unknown biological associations according to the domain-driven standards of practice and excellence that they value.

As the field study shows, if tools do not match scientists' intentions scientists will likely downgrade their goals, no longer accepting a tool as an aid for formulating an hypothesis. From this perspective, effective translational biomedical research hinges on tool designs matching scientists' higher order cognition as influenced by their domain knowledge and analytical practices.

The results of this field study suggest design objectives and strategies that may reduce mismatches. More research, prototyping, and formative evaluations are needed before requirements can be specified at a fine enough conceptual grain to inform scope how many tools and tool designs in a widespread way. Toward this end, field study results suggest that design choices should be informed by objectives and strategies related to: generating trust, reducing search and analysis spaces during classification activities, contextualizing relationships for causal explanations, highlighting and cuing biologically meaningful concepts, and giving users flexible interactivity for core analytical moves and strategies.

The Supplemental Material provides more details about these design strategies. Creating optimal designs that support scientists in integrating the multiple modes of reasoning required for explanatory analysis under uncertainty is the next great frontier in bioinformatics usability. In our national center, NCIBI, the results of this study are now being addressed through many modifications and re-designs to the tools, aimed at overcoming the three mismatches described here.

The field study aimed to analyze biomedical researchers' higher order cognitive processes for formulating hypotheses during analyses of protein-protein interactions. Results needed to be framed in a way that could inform tool designs for greater usefulness for higher order reasoning. As in other human-computer interaction studies in bioinformatics [ 37 ], qualitative field methods were used to explore scientists' work practices and cognitive processes. Twelve biomedical experimentalists from a large university Medical Center were observed and afterwards interviewed as they analyzed protein-protein interactions and related biological concepts to gain novel insights into disease mechanisms.

Two cellular biology experimentalists from the Department of Molecular, Cellular, and Developmental Biology and one biostatistician from the School of Public Health were also observed and interviewed. Four of them worked in pairs, as shown by the groupings in the table. Observations averaged 1. Interviews were conducted after each observation, lasting on average 20 minutes and totalling 8. The scientists studied different problems, diseases, and relationships. They proceeded at their own paces and defined their own intentions, analytical tasks, moves and strategies. All the scientists were familiar with and had some experience in systems biology analysis.

At the time of the field study, the MiMI database was comprised of , molecules and , interactions integrated from the ten databases [ 38 ]. During the course of the study, MiMI evolved from an XML database to a relational database to facilitate multi-user and arbitrary query functionality.

Interacting with the graphics, scientists were able to select data from the network and tabular views, sort tables, lay out networks based on predefined layouts, zoom, pan, and through extensive operations perceptually encode and filter data. They were able to use Cytoscape's color coding visual mapping and other available plug-ins, e. In scientists' naturalistic settings one to two observers took notes with IRB consent.

IRB consent assured anonymity to participants, no risk to their work or performance evaluations, and the freedom to end their participation at any time. The scientists performed and thought-aloud during analysis. Sessions were not video- or audio-taped; participants' laboratory spaces were often too small and noisy. Scientists' processes for entering queries were not studied. The two observers and interviewers were experienced and skilled in taking notes rapidly. Observers recorded missteps — those the scientists noted and those they did not.

In think-aloud comments, scientists typically conveyed and observers captured various task objectives, intentions, deliberations, lines of reasoning, confusions, confirmations, judgments about emerging findings, reactions to impasses, and satisfaction. Observers did not interrupt scientists as they worked nor did they guide scientists toward "correct usages" of tools or tool features. Non-structured interviews after observations sessions focused on scientists' cognition and needs for support from the tools but were tailored to the specific observations, research problem, and analytical objectives of each scientist.

Interviews asked scientists about their tasks, their reasoning behind task choices and behaviors, and their ordering and combining of tasks. Interview notes recorded scientists' responses verbatim — or close to verbatim — but did not similarly capture the questions posed by the interviewer, since he or she often doubled as the note-taker. Interview notes predominantly documented as best the interviewers could the exact language of verbal exchanges, sporadically adding impressionist notes that highlighted a theme or pattern that seemed relevant to the study.

Some scientists participated in additional interviews that involved follow up questions about a scientist's research project and methods. Using qualitative methods for grounded theory analysis adapted to design ends [ 39 ], notes of observations and interviews were read holistically several times and then critically analyzed.

For each case, narrative and procedural scenarios were constructed, capturing the scientist's analysis for his or her research problem. When pairs of scientists worked collaboratively, the observation of both individuals was treated as a single case scenario. For cases of analysis involving multiple observations, one unified scenario was constructed for the problem under study.

These cases typically just filled in details otherwise missing about reasoning, scientists' flow of analysis, and composite stages and tasks. Formal content coding was not applied because the data analysis objective was not so much to thematically or sociolinguistically characterize users and their work or to theorize about higher order scientific cognition per se. Rather the objective was to abstract context-driven patterns of thinking and behaviour that could inform design. Results from overly detailed coding typically do not translate readily into design. Analysis was informed by theories of higher order cognition for complex analysis and visual analytics rather than by cognitive models for low level procedures, which are typically the unit of study in cognitive task or hierarchical task analysis.

Other theories relevant to computer-supported complex tasks also framed analysis but not as pre-ordained conclusions. Relevant socio-technical conceptual frameworks from human-computer interaction, design, and visual cognition afforded looking at the data from multiple perspectives.

Outcomes were related to the analytical gaps in visualization tools identified in [ 26 ]. Items scientists saved or mentioned wanting to save in each case were identified to indicate if scientists placed enough value on outcomes and insights to store them for later personal reference, sharing, or both. Variations across cases were identified and explained. From this analysis, a user model organized around dominant cognitive processes in various stages of analysis was developed.

Abstract Background Current usability studies of bioinformatics tools suggest that tools for exploratory analysis support some tasks related to finding relationships of interest but not the deep causal insights necessary for formulating plausible and credible hypotheses.

Results Findings reveal patterns in scientists' exploratory and explanatory analysis and reveal that tools positively supported a number of well-structured query and analysis tasks. Conclusion As the next great frontier in bioinformatics usability, tool designs for exploratory systems biology analysis need to move beyond the successes already achieved in supporting formulaic query and analysis tasks and now reduce current mismatches with several of scientists' higher order analytical practices.

Background Technological advances have made exploratory analysis in systems biology accessible to large numbers of "everyday" biomedical researchers — i. Review of relevant research Several bioinformatics usability studies overtly or tacitly establish that scientists are not able to gain deep insights from bioinformatics tools intended to support exploratory analysis. Results Overview of common research and analysis practices Fifteen scientists researched distinct problems related to different diseases and putative mechanisms.

Table 1 Stages of exploratory and explanatory analysis shared across scientists. Example: Contextualize significant regulatory relationships in pathways. Story-building narrative reasoning and validation 0 Scientists sought to turn explanations about biological events into new, credible and plausible biological stories. Examples considered to be credible were not available based on scientists' progress.

Open in a separate window. Cognition and analysis in Confirmation During Confirmation, scientists primarily sought to trust the accuracy and completeness of the data and to be assured that the concepts, data, and interactivity offered by the tool fit their analytical intentions and practices as scientific experts and researchers. Table 2 Confirmation stage processes of validation.

Processes of Validation Actions Supported? Compare results to one's own experimental findings for affirmations and contradictions - Sort by gene name - Scroll to genes of interest - Hyperlink to details relevant to experiment Fully Determine accuracy of results by hunting for redundancies or synonyms - Sort by gene name - Scroll to various known genes - Check "Other gene name" field - Scroll to assure no duplication are displayed Fully Determine the accuracy of the data and the data sources - Search for cues or information indicating "data autobiography" or provenance e.

Cognition and analytical practices during Separating the Wheat from Chaff In the next stage, Separating the Wheat from Chaff, scientists classified genes and interactions by reading off data from the displays. They often combined their commonly applied heuristic strategy of looking for functionally similar molecules with other strategies and data, as this scientist reveals: The Description shows this one has the potential to be involved in some of the processes we're interested in.

Ideally, scientists wanted test statistics: What is the p-value of this interaction with MYC? Other surrogates included extracted sentences about interactions mined from full text PubMed Central articles — a feature implemented in later versions of MiMI-Cytoscape during field testing — and scientists' reliance on their own prior knowledge, for example: I see FLO9 interacts with a protein that I don't know. The transition from classification to mental modelling After finding genes and interactions of interest, scientists tacitly began to shift from asking "What? One of the scientists who had found relationships of interest now moved forward, describing this transition as follows: Lists don't make it now.

Specifically, scientists looked to see if the tools provided the following: Is there a physical interaction or regulation between them? One scientist who was studying the efficacy of lithium in bipolar disorder manually checked network displays against his spreadsheet of expression data and commented: If I manually cross-check this graph to some of the genes from my experiment.

Additionally, they sought to validate whether network configurations involving their interesting genes and relationships were by chance alone, as seen in the following think-alouds: Is there even something significant about this network structure that would not occur just by chance? Table 3 Common knowledge representations desired the transition.

Cognition and analytical practices during Beyond Read-offs The three scientists who engaged in Beyond Read-offs did not get very far in this stage. As one of the three scientists participating in Beyond Read-offs commented in think-alouds: These genes are involved in multiple concepts. Some of these overlapped with transition stage needs: Table 4 Support scientists would have liked for explanatory analysis.

Content Edges in networks weighted by biological traits Overlays of protein-protein interactions and disease associations Overlays of protein-protein interactions and relevant pathways Distinctions between proteins and other molecules that might serve as mediators of interactions, e. Discussion Results show many common patterns across cases in scientists' ways of knowing and reasoning but suggest, as well, that creating a match between a tool and a scientist's cognition might be specific to a scientist's domain specialization and analytical objectives.

My field study results show that for the explorations scientists conduct in explanatory systems biology analyses, tool designs and scientists' cognition are mismatched in the following three ways: 1. Mismatch related to validation Confidence in the data, tools, and one's own interpretations of knowledge representations was fundamental to scientists' willingness to engage in and continue engaging in systems biology analysis.

Mismatch related to transitions from classifying to model-based reasoning The importance of helping scientists make the transition from classification to model-based reasoning cannot be overemphasized. Mismatch related to causal mental modelling For causal mental modelling, the conceptual relationships that the scientists sought were fluid, dynamic, and not fully formalizable.

Conclusion In the current bioinformatics research literature, models of scientists' flows of analysis for systems biology explorations are incomplete. Methods The field study aimed to analyze biomedical researchers' higher order cognitive processes for formulating hypotheses during analyses of protein-protein interactions. Participants and their research Twelve biomedical experimentalists from a large university Medical Center were observed and afterwards interviewed as they analyzed protein-protein interactions and related biological concepts to gain novel insights into disease mechanisms.
