this article studies the generative grammar approach and some other theories driven from it to lexicon and lexical entries. generative grammar is known as a syntax-based theory, so some aspects of language which have been studied in this theory may have been ignored in other theories. this article shows that more attention has been given to lexicon and lexical entries since 50s. we may claim th...

This paper describes automatic techniques for mapping 9611 entries in a database of English verbs to WordNet senses. The verbs were initially grouped into 491 classes based on syntactic categories. Mapping these classiied verbs into WordNet senses provides a resource that may be used for disambiguation in multilingual applications such as machine translation and cross-language information retri...

This paper presents an ongoing task that will construct a DAML+OIL-compliant Chinese Lexical Ontology. The ontology mainly comprises three components: a hierarchical taxonomy consisting of a set of concepts and a set of relations describing the relationships among the concepts, a set of lexical entries associated with the concepts and relations, and a set of axioms describing the constraints on...

Automatic grammar extraction from annotated corpora (Xia, 1999; Chen and Vijay-Shanker, 2000; Chiang, 2000; Hockenmaier and Steedman, 2002; Miyao et al., 2004) enabled us to build a widecoverage lexicalized grammar at low cost. They succeeded in extracting a large number of lexical entries with less effort while conventional methods only allow limited lexical entries to be acquired in realworld...

This paper describes techniques to compile lexical entries in HPSG (Pollard and Sag, 1987; Pollard and Sag, 1993)-style grammar into a set of nite state au-tomata. The states in automata are possible signs derived from lexical entries and contain information raised from the lexical entries. The automata are augmented with feature structures used by a partial unication routine and de-layed/froze...

This work is a ‘prospective extension’ of the lexical work achieved in the DIINAR-MBC Euro-Mediterranean project. It aims at contributing to the crucial issue in the field of Arabic NLP of the operations involved in lemmatization, which are necessarily based on a definition of the Arabic entries of a monolingual or multilingual lexical database. As shown in previous work, lexical entries can be...

EDBL (Euskararen Datu-Base Lexikala) is a general-purpose lexical database used in Basque text-processing tasks. It is a large repository of lexical knowledge (currently around 80,000 entries) that acts as basis and support in a number of different NLP tasks, thus providing lexical information for several language tools: morphological analysis, spell checking and correction, lemmatization and t...

Unknown words are a hindrance to the performance of hand-crafted computational grammars of natural language. However, words with incomplete and incorrect lexical entries pose an even bigger problem because they can be the cause of a parsing failure despite being listed in the lexicon of the grammar. Such lexical entries are hard to detect and even harder to correct. We employ an error miner to ...
