Intelligent tools for the Semantic Web based on qualitative modelling – A new type of query: concept@location in time
University of Bremen – Center for Computing Technologies –
The number of web sites has increased drastically over the past few years.
Currently, billions of web pages supplying information to users. Modern
technology (e.g. multiagent systems) seem to be able to support the user
with his requests, browsing through the web automatically, returning answers.
However, the vast amount of web pages are unstructured or weakly structured,
which makes it impossible for machines to understand the semantics of the
content. The idea of the Semantic Web helps at this point: information
sources should be annotated with metadata following some kind of formalization.
machines are able to “understand” the meaning of the information sources and
can deliver more accurate answers.
The Bremen Semantic Translator for Enhanced Retrieval (BUSTER) follows the
idea of the Semantic Web annotating information sources with metadata
some kind of formalization. It is an ontology-based prototype that helps
applications or users to (a) find the needed information and (b) integrate
and/or translate this information for further processes. So far, a
logic-based approach for terminological reasoning and a graph-based approach for
reasoning about place names have been developed.
Another important part of search is time-dependent: people are looking for
hotels in areas at a certain time (e.g. during summer vacation) but do not
want to specify time according to the user-unfriendly W3C standard. Therefore, we
developed a new time representation and a new reasoning machine based on
Allen’s time intervals and Freksa’s semi-intervals. This leads to another
new type of query, namely concept@location in time.
I will give an overview about the overall BUSTER approach and will then
focus on the temporal part in detail.

INESC Brussels HUB Winter Meeting | JAN 25-26, 2024, in Porto
The INESC Winter Meeting, organized in collaboration with INESC Holding, is scheduled for January 25th and 26th, 2024, and it will be held in the city of Porto.
On January 25th, the primary goal is to bring together individuals from all five INESC institutes, fostering an environment that encourages networking, forging new connections, and collectively engaging in a forward-thinking exercise regarding the future of our research fields and the positioning of the INESC group within the European landscape.
There will be a welcome lunch, followed by an afternoon dedicated to collaboration, openness, and curiosity. The event will have a participatory approach, and will be guided by Dirk Stockmans, a highly experienced facilitator who has worked for the European Commission for the last 30 years.
Furthermore, all INESC researchers are invited to submit proposals for e-posters to be displayed at the Winter Meeting. Deadline for submissions is December 10 and more information is available here.
On January 26th, a senior administration and management committee will be held. Participants will be selected by each institute administration by invitation only.
If you would to take part on the 25th of January, please register here by November 30th.
The INESC Brussels HUB website will soon share more information about the venue and uptaded agenda.
