We investigate the effect of using wordspace models as an approximation of the kind of lexico-semantic and commonsense knowledge needed for coreference resolution of definite descriptions, that is, definite NPs with a common noun as head, for Swedish news text. We contrast a system using semantic knowledge from the word-space models with a semantically ignorant system and another system drawing...

We discuss the development of a multilingual lexicon linked to a formal ontology. First we describe the Open Multilingual Wordnet, a multilingual wordnet with twenty two languages and a rich structure of semantic relations. It is made by exploiting links from various monolingual wordnets to the English Wordnet. Currently, it contains 118,337 concepts expressed in 1,643,260 senses in 22 language...

This paper describes an unsupervised method for extracting lexico-semantic classes from POS annotated corpora. The method consists in building bi-dimensional clusters of both words and local syntactic contexts. Each cluster, which represents a lexicosemantic class such as “entities in danger” is the result of merging its most prototypical constituents (words and contexts). The generated cluster...

This paper aims to foster discussion of the means by which bilinguals control their two language systems. It proposes an inhibitory control (IC) model that embodies the principle that there are multiple levels of control. In the model a language task schema (modulated by a higher level of control) "reactively" inhibits potential competitors for production at the lemma level by virtue of their l...

In this paper, we evaluate different lexico-syntactic patterns in regard to their usefulness for ontology building. Each pattern is analysed individually to determine its respective probability to return the hyponymy relation. We also create different ontologies according to this accuracy criteria to show how it influences the resulting ontology. Using patterns with a success rate over 80% lead...

In this work, we consider the problem of placing replicas in a data center or storage area network, represented as a digraph, so as to lexico-minimize a previously proposed reliability measure which minimizes the impact of all failure events in the model in decreasing order of severity. Prior work focuses on the special case in which the digraph is an arborescence. In this work, we consider the...
