Efficient Implementation of Semantic Relations in Lexical Databases
In this paper we develop a formalization of semantic relations that facilitates efficient implementations of relations in lexical databases or knowledge representation systems using bases. The formalization of relations is based on a modeling of hierarchical relations in Formal Concept Analysis. Further, relations are analysed according to Relational Concept Analysis which allows a representati...
متن کاملNon-Classical Lexical Semantic Relations
NLP methods and applications need to take account not only of “classical” lexical relations, as found in WordNet, but the lessstructural, more context-dependent “nonclassical” relations that readers intuit in text. In a reader-based study of lexical relations in text, most were found to be of the latter type. The relationships themselves are analyzed, and consequences for NLP are discussed.
متن کاملSimple_PLUS: a network of lexical semantic relations
The present article deals with the Italian lexical-semantic database Simple_PLUS and focuses on its essential core, i.e. the network of lexical semantic relations. This lexical resource builds on Parole-Simple-Clips, a four-layered electronic lexicon of Italian, founded on the SIMPLE model. Simple_PLUS consists of 30,000 semantic entries, partly imported from the source lexicon and partly newly...
متن کاملLearning Lexical Semantic Relations using Lexical Analogies — Extended Abstract
Linguistic ontologies, most notably WordNet [1], have been shown to be a valuable resource for a variety of natural language processing applications. Presently, linguistic ontologies are largely constructed by hand, which is both difficult and expensive. A central problem that demands an automated solution is the discovery and incorporation of lexical semantic relations, or semantic relations b...
متن کاملUTD: Classifying Semantic Relations by Combining Lexical and Semantic Resources
This paper describes our system for SemEval-2010 Task 8 on multi-way classification of semantic relations between nominals. First, the type of semantic relation is classified. Then a relation typespecific classifier determines the relation direction. Classification is performed using SVM classifiers and a number of features that capture the context, semantic role affiliation, and possible pre-e...
