  • Project proposal in Web 2.0 the guy reviewed only MAS work in Web 2.0. What about Web 2.0? How many of you heard about multi-agent Web 2.0 systems?
  • Not only communities, but also form – blog, presentation, etc
  • Our definition covers most of the existing definitions
  • Transcript of "Diversity-aware search for people, content, events AND Diversity-aware hiring and evaluation"

    1. 1. Trusting Differently: Diversity-aware search for people, content, events Judith Simon, Institut Nicod, CNRS Aliaksandr Birukou , University of Trento, Italy [Insert header here] [Insert footer]
    2. 2. Motivation <ul><li>Information overload </li></ul><ul><li>Paradoxically - Narrowing the scope </li></ul><ul><li>People tend to (implicitly) trust known content, people, events </li></ul><ul><li>“ See only what you want to see, hear only what you want to hear, read only what you want to read” Cass Sunstein </li></ul><ul><li>&quot;It's what you don't know that can kill you” J. Mullins </li></ul><ul><li>“ The scarce resource now is the attention” Bernardo Huberman </li></ul>[Insert header here] [Insert footer]
    3. 3. Question 1 - What is your discipline? <ul><li>Computer Science: 24 </li></ul><ul><li>Social sciences: 2 </li></ul><ul><li>Philosophy: 3 </li></ul><ul><li>Sociology of science: 1 </li></ul><ul><li>Physical systems: 1 </li></ul><ul><li>Unknown: 2 </li></ul>[Insert header here] [Insert footer]
    4. 4. Question 2 <ul><li>How many of you met people from another discipline working on trust before? </li></ul>[Insert header here] [Insert footer]
    5. 5. Scientific entities <ul><li>People: researchers, readers </li></ul><ul><li>Content: papers, articles, datasets, blogs, </li></ul><ul><li>Events: conferences, workshops, summer schools </li></ul><ul><li>… plus publication venues : journals, newspapers, magazines, open repositories </li></ul>[Insert header here] [Insert footer] /13
    6. 6. Dimensions of content <ul><li>Relevance </li></ul><ul><li>Reputation </li></ul><ul><li>… </li></ul>[Insert header here] [Insert footer] /13
    7. 7. One more dimension - diversity [Insert header here] [Insert footer]
    8. 8. Roadmap <ul><li>Fix two out of three dimensions: </li></ul><ul><ul><li>Relevance – metrics from information retrieval </li></ul></ul><ul><ul><li>Reputation – based on links or citations </li></ul></ul><ul><li>Design diversity metrics: </li></ul><ul><ul><li>Existing research on diversity in web search </li></ul></ul><ul><ul><li>Community network of scientific entities </li></ul></ul><ul><li>Apply results </li></ul><ul><ul><li>To discover hidden links between scientific entities </li></ul></ul><ul><ul><li>To analyze and avoid conflicts of interest </li></ul></ul>[Insert header here] [Insert footer]
    9. 9. Desired outcome <ul><li>A recommender system that </li></ul><ul><ul><li>Recommends content, events, people to researchers </li></ul></ul><ul><li>Matches papers with reviewers </li></ul><ul><ul><li>To get diverse viewpoints on the same paper </li></ul></ul><ul><li>Assigns papers to panels/sessions with different degrees of similarity/diversity </li></ul><ul><ul><li>To increase homogeneity or have more vivid discussion </li></ul></ul>[Insert header here] [Insert footer] /13
    10. 10. What we need <ul><li>Topic discovery </li></ul><ul><ul><li>… e.g., by keyphrase extraction </li></ul></ul><ul><li>Trust and reputation metrics </li></ul><ul><ul><li>… but we are probably in the right place </li></ul></ul>[Insert header here] [Insert footer] /13

    13. 13. Motivation <ul><li>You’ve seen that already… </li></ul><ul><li>Now, consider hiring committees </li></ul><ul><li>Same problems – select people similar to you/group/department </li></ul>[Insert header here] [Insert footer] /13
    14. 14. Argument <ul><li>Hiring people different from the ones already working in the research group, department, or university can bring new contacts, viewpoints and communities </li></ul><ul><ul><li>But only if the person has all required competences </li></ul></ul>[Insert header here] [Insert footer] /13
    15. 15. <ul><li>Culture includes: </li></ul><ul><ul><li>experience </li></ul></ul><ul><ul><li>[patterns of] behavior </li></ul></ul><ul><ul><li>knowledge </li></ul></ul><ul><ul><li>beliefs </li></ul></ul><ul><ul><li>norms </li></ul></ul><ul><ul><li>… </li></ul></ul><ul><li>Culture is: </li></ul><ul><ul><li>shared </li></ul></ul><ul><ul><li>accummulated </li></ul></ul><ul><ul><li>learned </li></ul></ul><ul><ul><li>socially transmitted </li></ul></ul><ul><ul><li>socially acquired </li></ul></ul><ul><ul><li>… </li></ul></ul>Defining culture.

    16. 16. Metrics on scientific/cultural difference <ul><li>Scientific traits: where publish, research interests, … </li></ul><ul><li>Culture traits: experience, patterns of behaviors, beliefs, knowledge, … </li></ul><ul><li>Metrics can be based on the differences between “the culture” of an individual and the research group/department: </li></ul><ul><ul><li>Common culture (culture overlap) is the set of traits that is present in both cultures </li></ul></ul><ul><ul><li>Culture similarity is the degree to which two cultures are similar, i.e. how much they have in common </li></ul></ul><ul><ul><li>Culture fit is the ratio between the culture overlap and the number of traits in the other culture </li></ul></ul>[Insert header here] [Insert footer] /13
    17. 17. Judging people from other communities <ul><li>Improve the reputation of a stranger by showing where she stays in her community (top 5%/bottom 10%) </li></ul>[Insert header here] [Insert footer] /13
    18. 18. But… <ul><li>How do you define “top 5%” or “bottom 10%”? </li></ul>[Insert header here] [Insert footer] /13
    19. 19. uCount <ul><li>Community-defined index </li></ul><ul><li>The goal is to put in place a merit-based, objective, transparent system for assessing people, contributions, and events, one that does not simply focus on &quot;impact&quot; but focuses on the wide range of contributions that can be made </li></ul><ul><li>Will be maintained by ICST and EAI </li></ul><ul><li>Please volunteer to become a member of the uCount council </li></ul>[Insert header here] [Insert footer] /13
    20. 20. Call for members of uCount council <ul><li>What is required </li></ul><ul><ul><li>Willingness to help your community to design better metrics, metrics that matter </li></ul></ul><ul><ul><li>Some spare time to define selection procedures, tools for community interaction </li></ul></ul><ul><ul><li>Some spare time for involving your community in finding what matters for them (see Dumas et al – correlation between metrics) </li></ul></ul><ul><li>Timeline </li></ul><ul><ul><li>Expression of interest: by January 4 th </li></ul></ul><ul><ul><li>Involving your community: by January 30th </li></ul></ul>[Insert header here] [Insert footer] /13
