Motivation

o Information overload

o Paradoxically - Narrowing the scope

o People tend to (implicitly) trust known content, people, events

“See only what you want to see, hear only what you want to hear, read only what you want to read” Cass Sunstein

"It's what you don't know that can kill you” J. Mullins

“The scarce resource now is the attention” Bernardo Huberman

Question 2

o How many of you met people from another discipline working on trust before?

Scientific entities

o People: researchers, readers

o Content: papers, articles, datasets, blogs,

o Events: conferences, workshops, summer schools

o …plus publication venues: journals, newspapers, magazines, open repositories

Roadmap

o Fix two out of three dimensions: o Relevance – metrics from information retrievalo Reputation – based on links or citations

o Design diversity metrics:o Existing research on diversity in web searcho Community network of scientific entities

o Apply resultso To discover hidden links between scientific entitieso To analyze and avoid conflicts of interest

Desired outcome

o A recommender system thato Recommends content, events, people to researchers

o Matches papers with reviewerso To get diverse viewpoints on the same paper

o Assigns papers to panels/sessions with different degrees of similarity/diversityo To increase homogeneity or have more vivid discussion

What we need

o Topic discoveryo … e.g., by keyphrase extraction

o Trust and reputation metricso … but we are probably in the right place

Motivation

o You’ve seen that already…

o Now, consider hiring committees

o Same problems – select people similar to you/group/department

13/13

Argument

o Hiring people different from the ones already working in the research group, department, or university can bring new contacts, viewpoints and communitieso But only if the person has all required competences

Metrics on scientific/cultural difference

o Scientific traits: where publish, research interests, …

o Culture traits: experience, patterns of behaviors, beliefs, knowledge, …

o Metrics can be based on the differences between “the culture” of an individual and the research group/department:o Common culture (culture overlap) is the set of traits that is present in

both cultureso Culture similarity is the degree to which two cultures are similar, i.e.

how much they have in commono Culture fit is the ratio between the culture overlap and the number of

traits in the other culture

Judging people from other communities

o Improve the reputation of a stranger by showing where she stays in her community (top 5%/bottom 10%)

But…

o How do you define “top 5%” or “bottom 10%”?

uCount

o Community-defined index

o 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 "impact" but focuses on the wide range of contributions that can be made

o Will be maintained by ICST and EAI

o Please volunteer to become a member of the uCount council

Call for members of uCount council

o What is requiredo Willingness to help your community to design better metrics,

metrics that mattero Some spare time to define selection procedures, tools for

community interactiono Some spare time for involving your community in finding what

matters for them (see Dumas et al – correlation between metrics)

o Timelineo Expression of interest: by January 4th

o Involving your community: by January 30th
