  4. Biological Storytelling • Reason across multiple types of experimental data • Formulate hypotheses and high-level descriptions

  5. Supporting Synthesis Tasks of Biomedical researchers • Most bioinformatics tools support analysis, but not synthesis activities of bioscience researchers • Synthesis involves: • keeping track of the diverse pieces of information collected during database searches and other data analysis activities, and • organizing and using the diverse information, formulating hypotheses and higher-level explanations • E.g. elucidating the structure and function of biological pathways. • validating hypotheses and higher-level explanations against detailed experimental data • sharing the information with colleagues and working collaboratively to refine hypotheses.

  6. Aspects of Synthesis workFindings from User Research • Like detective work, “mind-mapping” • Information is “free-form”, semi-structured • Multiple hypothesis/alternatives • Group work, multiple perspectives, views • Grouping together chunks of related information • Verbal and visual reasoning • Notepads, whiteboards, lab notebooks

  7. The Role of Narrative • Many biologists talked in terms of "piecing together a story“… • of what a gene does, how it fits into a pathway with other genes, proteins… • Cognitive/social psychology research finds that people use storystructure as a way of organizing and remembering information • Thorndyke, Shank, Middleton and Edwards, Erickson, Gershon and Ward • Useful story development software tools exist for other domains • E.g. screenwriting, video production

  8. Main concepts of our software • Free-form data model • Narrative Structure • “Top down” hypothesis formulation, “bottom-up” data exploration • Annotation • Multi-disciplinary Collaboration

  9. ITEMS • Basic “atomic” unit of information • Represent “biological entities” – genes, proteins, … • Sortable on multiple keys • Group selectable • Populate manually or semi-automatically • Links to detailed experimental data • Links to public data and literature • Data values can be color-encoded

  10. COLLECTIONS • Free-form sets of items • Malleable • split, merge, add, move • Represent cognitive chunks • Can be nested • Populate manually or semi-automatically • Links to detailed experimental data • Links to public data and literature

  11. STORIES • Represent state of biological hypotheses and understandings • Represent paths explored and alternative hypotheses • Support for deliberation via Support/Oppose story nodes • Links to detailed experimental data • Links to public data and literature • Narrative structure as an organizing principle

  12. Story Grammar Source: Thorndyke, P.W. (1977), "Cognitive Structures in Comprehension and Memory of Narrative Discourses", Cognitive Psychology, 9, pp. 77-110

  13. PUTTING THE STORY TOGETHER GRAPHICALLY • Graphical network diagram is common visual metaphor in molecular biology • Pathways, protein/protein interaction networks • Represent the “nouns” and “verbs” of biological stories • Nouns = biological entities (genes, proteins), (players), • verbs = relationships between biological entities (promotes, inhibits)

  14. SEMANTIC OVERLAYS • For validating high-level explanations, hypotheses against data • Juxtapose data values onto elements of graphical and textual stories • “step through” experimental data columns and “light up” elements of graphical and textual stories • Analogy to qualitative simulation

  15. Support for Multidisciplinary Collaboration • Annotation is tagged with user name and timestamp • Support and Oppose story nodes document alternative lines of thought • Web repository enables review by non-users of system “… we build up a consensus hallucination about what is going on in the living cell… (NHGRI)”

  16. Annotation • Every system element can have arbitrary textual notes • Citations can be dragged/dropped from the Web-based literature • Citations can have attached notes/comments • Annotations interlinked with system elements, other annotations

  17. Web Repository

  18. Usage Feedback • How much structure is just right? • Flexibility in story grammar (tags vs. rigid structure) • Diversity in grouping (columns as well as rows) • Diagrammatic vocabulary • Biochemical reactions vs. signal transduction

  19. Related Work • Digital storytelling • Storyspace (EastGate Systems) • Personal information management • Lotus Agenda • Issue-Based Information Systems • Rittel, McCall, Conklin & Begeman • Biological Pathway Databases • STKE, BIND, KEGG, EcoCyc, TransPath, SPAD, … • Semantic overlays • EcoCyc, GenMAP (gene expression on pathways) • Kenna Technologies (qualitative simulation) • Diagrammatic UIs to cell and pathway information • CellSpace (Cellomics) • Biological information management • eLabBook (LabBook, Inc.)

  20. Future work • Multiple data types • Support a “systems” perspective on biology • Utilization of data mining, computational tools • Duality between graphical and textual storytelling • Richer annotation • Richer diagrammatic semantics • Scaling
