We propose a strongly lexicalist treatment of translation equivalence where mismatches due to diverging lexicalization patterns are dealt with by means of translation links which capture crosslinguistic generalizations across sets of semantically related lexical items. We show how this treatment can be developed within a unification-based, multilingual lexical knowledge base which is integrated...

Lexical chaining is a method for encapsulating the meaning of a document in so-called lexical chains. The presence and concentration of such chains can be used to judge similarities both within and between documents. We present a system that performs such chaining and, using a small corpus of news articles, compare its performance with that of a naive vector-space system. We then investigate th...

One of the hardest problems for knowledge extraction from machine readable textual sources is distinguishing entities and events that are part of the main story from those that are part of the narrative structure, hnportantly, however, reported sl)eech in newspaper articles explicitly links these two levels. In this paper, we illustrate what the lexical semantics of reporting verbs must incorpo...

FIPS, a multilingual deep parser, has been developed at the Language Technology Laboratory (LATL) of the University of Geneva (Switzerland).This parser, inspired by Chomskyan generative theories, is based on the idea that sets of syntactic structures are common to different languages (to all languages or to some language families). In this paper, we present an introduction to FIPS processing th...

INTRODUCTION This article is part of the Focus Theme of METHODS of Information in Medicine on "Managing Interoperability and Complexity in Health Systems". OBJECTIVES In previous work, we have defined methods for the extraction of lexical patterns from labels as an initial step towards semi-automatic ontology enrichment methods. Our previous findings revealed that many biomedical ontologies c...

The research presented in this paper is part of a larger project on the semi-automatic generation of definitions of semantically-related terms in specialized resources. The work reported here involves the formulation of instructions to generate the definitions of sets of morphologically-related predicative terms, based on the definition of one of the members of the set. In many cases, it is ass...

We propose a method for computing semantic relatedness between words or texts by using knowledge from hypertext encyclopedias such as Wikipedia. A network of concepts is built by filtering the encyclopedia’s articles, each concept corresponding to an article. Two types of weighted links between concepts are considered: one based on hyperlinks between the texts of the articles, and another one b...

We present UBY-LMF, an LMF-based model for large-scale, heterogeneous multilingual lexical-semantic resources (LSRs). UBY-LMF allows the standardization of LSRs down to a fine-grained level of lexical information by employing a large number of Data Categories from ISOCat. We evaluate UBY-LMF by converting nine LSRs in two languages to the corresponding format: the English WordNet, Wiktionary, W...
