How do you connect with people?

You try and get to know them.

The Web is a source of information for knowing people.

UNOPORUNO has been designed to find that information.

Why UNOPORUNO? Isn’t GOOGLE enough?

Results obtained using UNOPORUNO

Snippets ordered by their potential value for finding

relevent information on highly skilled

members of a diaspora:

The Top 5

Statistically, the TOP 5 represents roughly 2,5% of all the snippets generated by Google (Turner et al., CIC Conference, Mexico City, October 2012)

The UNOPORUNO filters used to identify the Top 5 information sources for

knowing a person are relevent in 80% of the cases (Garcia Flores et al., JAPTAL, oct. 2012)

UNOPORUNO filters are designed to find people on the move.

The system shows its conclusion here:

But it invites the user to make the final decision and determine the

« status real »

UNOPORUNO learns from user’s decisions

High Value Snippets : allow direct access to CV’s , personal or institutional Web pages enabling a user to decide on mobility status

Medium Value Snippets: point to web pages which don’t allow a user to decide upon home country or host country affiliations:

• Where does a Uruguayan scientist who published an article in 2010 during her post-doc in a French lab live now? In France or in Uruguay?

• An article in a scientific journal doesn’t contain the information needed to decide upon the mobility status of a person. A CV or a personal Web page generally does.

Low Value Snippets: common names such Michael Jackson, the singer, and Michael Jackson, the biologist, illustrate the « homonym problem » which causes UNOPORUNO to produce snippets which have low information value

User satisfaction depends, first, upon the capacity of UNOPORUNO to present

high value snippets in the Top 5 Results of a case study done on a corpus containing 300 names

10


10User satisfaction depends, second, upon the time taken by users to

process UNOPORUNO information

The time taken to process 300 names was roughly 3000 minutes or about 50 hours

Describing patterns of mobility
