Usage notes as the basis for a representation of near-synonymy for lexical choice (or Making words of senses)

چکیده
The task of choosing between lexical near-equivalents in text generation requires the kind of knowledge of ne di erences between words that is typi ed by the usage notes of dictionaries and books of synonym discrimination. These usage notes follow a fairly standard pattern, and a study of their form and content shows the kinds of di erentiae adduced in the discrimination of nearsynonyms. For appropriate lexical choice in text generation and machine translation systems, it is necessary to develop the concept of formal `computational usage notes', which would be part of the lexical entries in a conceptual knowledge base. The construction of a set of `computational usage notes' adequate for text generation is a major lexicographic task of the future. 1 Lexicons for lexical choice 1.1 Lexical choice and plesionymy The problem of lexical choice in text generation is to determine the word that conveys most precisely the denotation and connotation that are to be expressed.

Automatic Contexonym Organizing Model (ACOM)
Normal language user’s word-association intuition (e.g. drunken – stagger) raises questions about the mental lexicon organization and its application for natural language processing tasks. We present an automatic contextually related words (contexonym) organizing model (ACOM) that reflects this intuition, giving one of the possible answers to this question. Trained on large corpora, the model (...
متن کاملNear-synonymy and the structure of lexical knowledge
Plesionyms, or near-synonyms, are words that are almost synonyms, but not quite. The need to deal adequately with plesionymy in tasks such as lexical choice is the basis for two alternatives to conventional models of lexical knowledge: a Saussurean approach and a prototype-theory approach. In this paper, I will discuss these approaches, showing that the latter is troublesome but the former is l...
