Informatics and Telematics Institute invites you to the lecture given by Simone Santini (, Escuela Politecnica Superior, Universidad Autonoma de Madrid, on "SEMANTICS, CONTEXT, AND FRIENDS", on Wednesday, 22 July, at 12:00 in the roon Zephyros of Centre of Research and Technology Hellas.

this "spoken business card", I will try to briefly describe that part
of my current activities that has some relevance to semantic issues. I
am considering semantics under two aspects (symbolized, in  the title,
by the words "context" and "friends"). The first is the autonomous
creation of meaning by the searcher during the search  process. In this
process, I argue, the context in which any particular  search is made
plays as important a role as the contents of the documents that are
being searched, so that one should devote at least as much effort to
model the context of a search as it is given to modeling the contents
of documents. I will present our efforts in this direction, especially
in the use of the contents of one's working directories as
representative of the context in which a search is made during a
particular activity.

second aspect is the community creation of meaning. In this area I am
working with the University of Milano on the way in which the members
of photo-sharing communities can be used as "semantic classifiers" for
the photos that one user is placing on the internet. The friends
(wizards) that are considered as most useful cor the kind of
classification that the given user (the apprentice) is doing
are retained in a pool that is updated dynamically using principles
akin to genetic algorithms. The photos of these wisards are used
as classifiers to suggest possible classifications to the apprentice.
