On Some Criteria for Defining Lexical Semantics

Choices for Lexical Semantics

The modern computational lexical semantics has reached a point in its development when it has become useful to compare the goals and methods of the various approaches to it. This article proposes several choices in terms of which these goals and methods can be discussed. It is argued that the central questions include the use of lexical rules for generating word senses; the role of syntax and f...

Lexical Semantics-Syntactic Model for Defining and Subcategorizing Attribute Noun Class

Either word sense classification or word sense clustering can not avoid this problem: what features people can get from word meaning that can be used as the tools employed for producing word sense ontology. In this paper, we present a lexical semantic-syntactic model to define and subcategorize a noun class—attribute noun class, by acquiring syntactic behavior and semantic restrictions from cor...

Morphological Cues for Lexical Semantics

Most natural language processing tasks require lexical semantic information. Automated acquisition of this information would thus increase the robustness and portability of NLP systems. This paper describes an acquisition method which makes use of fixed correspondences between derivational affixes and lexical semantic information. One advantage of this method, and of other methods that rely onl...

Lexical Resources for Semantics Extraction

In this paper, we report our work on the creation of a number of lexical resources that are crucial for an interlingua based MT from English to other languages. These lexical resources are in the form of sub-categorization frames, verb knowledge bases and rule templates for establishing semantic relations and speech act like attributes. We have created these resources over a long period of time...
