Lexical Knowledge Bases
نویسنده
چکیده
A lexical knowledge base is a repository of computational information about concepts intended to be generally useful in many application areas including computational linguistics, artificial intelligence, and information science. It contains information derived from machine-readable dictionaries, the full text of reference books, the results of statistical analyses of text usages, and data manually obtained from human world knowledge.

Multilingual Lexical Knowledge Bases: Applied WordNet Prospects
The idea of a Lexical knowledge base was recently proposed by the ESPRIT BRA AQUILEX [Briscoe 91], [Calzolari 92] project, to provide information, mostly of a semantic nature, internally consistently structured and electronically available. Three levels of lexical representation are proposed in AQUILEX: (a) Machine Readable Dictionary (MRD), i.e. an electronic version of the paper dictionary; (...
متن کاملA Method to Generate Large Common-Sense Knowledge Bases from Online Lexical Resources
This paper presents a general method to automatically build large knowledge bases from online lexical resources. While our experiments were limited to generate a knowledge base from WordNet, an online lexical database, the method is applicable to any type of dictionary organized around the elementary structure lexical entry definition(s). The advantages of using WordNet, or richer online resour...
متن کاملVerbKB: A Knowledge Base of Verbs for Natural Language Understanding
A verb is the organizational core of a sentence. Understanding the meaning of the verb is, therefore, a key to understanding the meaning of the sentence. One of the ways we can formulate natural language understanding is by treating it as a task of mapping natural language text to its meaning representation: entities and relations anchored to the world. Since verbs express relations over their ...
متن کاملLexical Databases as a Base for Broad Coverage Ontologies
The paper deals with current lexical databases that are seen as a basis for broad-coverage general-purpose ontologies. Various extensions and refinements of existing multilingual lexical knowledge bases are proposed with the aim of improving the capabilities of these resources. The main goal lies in the effort to gain a better lexical knowledge representation, which is crucial to coping with th...
متن کاملControlling The Application Of Lexical Rules
In this paper, we describe an item-familiarity account of the semi-productivity of morphological and lexical rules, and illustrate how it can be applied to practical issues which arise when building large scale lexical knowledge bases which utilize lexical rules. Our approach assumes that attested uses of derived words and senses are explicitly recorded, but that productive use of lexical rules...
متن کاملVirtual Linked Lexical Knowledge Base for Causality Reasoning
The A virtually linked knowledge base is designed to utilize a pre-constructed knowledge base in a dynamic mode when it is in actual use. An algorithm is proposed for causality reasoning based on a set of lexical knowledge bases that contain information about such items as event role, is-a hierarchy, relevant relation, antonym, and other features. These lexical knowledge bases have mainly made ...
