lexical semantics

Definitions

  • WordNet 3.6
    • n lexical semantics the branch of semantics that studies the meanings and relations of words
    • ***

Usage


In news:

We present an approach to building a verb lexicon compatible with WordNet but with explicitly stated syntactic and semantic information, using Levin verb classes to systematically construct lexical entries.

Kunze’s theory of semantic emphasis (Theorie der semantischen Emphase ) is under development for the lexical entries of the text analysis pro ject kontext [Firzlaff and Haenelt, 1992].
Emphatic generation: employing the theory of semantic emphasis for text generation
According to the algorithm described in Figure 4, and due to the syntactic-head and semantic-head link relation, the lex rule can only be applied to the lexical entry for sentence (Figure 1).

Semantic Kernel (SK) Information: Semantic structure completely which is predictible from the lexicon (i.e, there is at least one lexical entry which subsumes this structure).

Non Semantic Kernel (Non-SK) Information: Semantic structure which is not predictible from any lexical entry (typically, lists).

Explicitation This is a subcategory of semantic modification, which is assigned if the target transeme is lexically more specific than the source transeme. A clear case of explicitation is when extra information has been added to the transeme.

Otherwise when the similarity is semantic, lexical search methods must be used.

Lexical semantics provides an original approach for the term spotting task. Generally speaking, the main topics addressed by a document are expressed by ambiguous words.
Inferring knowledge from a large semantic network
Research in this area has arisen out of the success of vector-based techniques for representing aspects of lexical semantics, such as latent semantic analysis (Deerwester et al., 1990) and measures of distributional similarity (Lin, 1998; Lee, 1999).
