AbstractSemantic networks have shown considerable utility as a knowledge representation for Natural Language Processing (NLP). This paper describes a system for automatically deriving network structures from machine-readable dictionary text. This strategy helps to solve the problem of vocabulary acquisition for large-scale parsing systems, but also introduces an extra level of difficulty in terms of word-sense ambiguity. A Preference Semantics parsing system that operates over this network is discussed, in particular as regards its mechanism for using the network for lexical selection
WordNet: An Electronic Lexical Reference System Based on Theories of Lexical Memory
Cet article fait la description de WordNet, systĂšme de rĂ©fĂ©rence Ă©lectronique, dont le dessin est basĂ© sur des thĂ©ories psycholinguistiques concernant la mĂ©moire lexicale et lâorganisation mentale des mots.Les noms, les verbes et les adjectifs anglais sont organisĂ©s en groupes synonymes (les « synsets »), chacun reprĂ©sentant un concept lexical. Trois relations principales â lâhyponymie, la mĂ©ronymie et lâantonymie â servent Ă Ă©tablir les rapports conceptuels entre les « synsets ». Les prĂ©suppositions qui lient les verbes sont indiquĂ©es ainsi que leurs contextes syntaxiques et sĂ©mantiques.En tĂąchant de miroiter lâorganisation mentale des concepts lexicaux, WordNet pourrait servir lâutilisateur sans formation en linguistique.This paper describes WordNet, an on-line lexical reference system whose design is based on psycholinguistic theories of human lexical organization and memory.English nouns, verbs, and adjectives are organized into synonym sets, each representing one underlying lexical concept. Synonym sets are then related via three principal conceptual relations: hyponymy, meronymy, and antonymy. Verbs are additionally specified for presupposition relations that hold among them, and for their most common semantic/syntactic frames.By attempting to mirror the organization of the mental lexicon, WordNet strives to serve the linguistically unsophisticated user
Génération automatique de définitions pour le français
Definition modeling is a recent task that aims at producing dictionary definitions based on wordembeddings. We observe two gaps : (i) the current state of the art has yet to tackle languages otherthan English or Chinese and (ii) the purported usability as an evaluation method for word embeddingshas yet to be verified. Hence we propose a dataset for French definition modeling and evaluate howusing different input embeddings impacts the performances of a simple definition modeling system.La gĂ©nĂ©ration de dĂ©finitions est une tĂąche rĂ©cente qui vise Ă produire des dĂ©finitions lexicographiques Ă partir de plongements lexicaux. Nous remarquons deux lacunes : (i) lâĂ©tat de lâart actuel ne sâest penchĂ© que sur lâanglais et le chinois, et (ii) lâutilisation escomptĂ©e en tant que mĂ©thode dâĂ©valuation des plongements lexicaux doit encore ĂȘtre vĂ©rifiĂ©e. Pour y remĂ©dier, nous proposons un jeu de donnĂ©es pour la gĂ©nĂ©ration de dĂ©finitions en français, ainsi quâune Ă©valuation des performances dâun modĂšle de gĂ©nĂ©ration de dĂ©finitions simple selon les plongements lexicaux fournis en entrĂ©e
