Linking Named Entities to the Corresponding Wikipedia Pages
INESC-ID Lisboa and IST –
This talk will present participation of the DMIR/INESC-ID team on the Monolingual Knowledge Base Population (KBP) track at the 2011 Text Analysis Conference (TAC-KBP — http://nlp.cs.qc.cuny.edu/kbp/2011/), for which we developed a supervised learning approach to the task of linking named entities in an english text to global unique identifiers. Formally, the KBP problem consists in linking named entities (queries) and the respective texts where they occur, to the corresponding entries in a knowledge base (i.e., a subset of the English Wikipedia). If there are no such entries, the systems are required to cluster together the queries referring to the same non-KB (NIL) real world entity. We modeled the aforementioned problem through three supervised learning tasks, namelly (a) ranking candidate knowledge base disambiguations for each named entity, (b) classifying the top-ranked disambiguations as correct or not (i.e., finding the NIL queries), and (c) classifying pairs of queries with an estimated incorrect disambiguation as referring to the same entity or not, so that the transitive closure of these pairs can form the set of equivalence classes (i.e., the NIL clusters). The talk we detail the features and the learning methods used for modeling the three tasks, also presenting an analysis of the obtained results.

Workshop “Metabolism and mathematical models: Two for a tango” – 2nd Edition
Title: Workshop Metabolism and mathematical models: Two for a tango – 2nd Edition
Dates: October 25-26, 2022
Location: This workshop will be held in a virtual way
The topic of this workshop is metabolism in general, with a special focus, although not exclusive, on parasitology. Besides an exploration of the biological, biochemical and biomedical aspects, the workshop will also aim at presenting some of the mathematical modelling, algorithmic theory and software development that have become crucial to explore such aspects.
This workshop is being organised in the context of two projects, both with the Inria European Team Erable. One of the projects involves a partnership with the University of São Paulo (USP), in São Paulo, Brazil, more specifically the Institute of Mathematics and Statistics (IME) and the Institute of Biomedical Sciences – Inria Associated Team Capoeira – and the other involves the Inesc-ID/IST in Portugal, ETH in Zürich and EMBL in Heidelberg – H2020 Twinning Project Olissipo.
The workshop is open to all members of these two projects but also, importantly, to the community in general.
The program and more details are available here.
