Several works in computational linguistics try to study the relationships among dictionary entries. These works consider the dictionary as a graph where words are represented by vertices and relationships between two words by an arrow between the corresponding vertices. Several kinds of relationships exist between two words such as synonymy, antonymy, hyperonymy, hyponymy ... We define the prox...

Lexical cohesion is a property of text, achieved through lexical-semantic relations between words in text. Most information retrieval systems make use of lexical relations in text only to a limited extent. In this paper we empirically investigate whether the degree of lexical cohesion between the contexts of query terms’ occurrences in a document is related to its relevance to the query. Lexica...

The Semantic Web needs ontologies as an integral component. Current methods for learning and enhancing ontologies, need to be further improved to overcome the knowledge acquisition bottleneck. The identification of concepts and relations with only minimal user interaction is still a challenging objective. Current approaches performed to extract semantics often use association rules or clusterin...

HowNet is an on-line common-sense knowledge base unveiling inter-conceptual relations and inter-attribute relations of concepts as connoting in lexicons of the Chinese and their English equivalents [1]. Each concept is represented and understood by their definition and association links to other concepts. To Compare with WordNet, HowNet’s architecture provides richer information apart from hypo...

1 WordNet In 1978, George Miller started the development of a database with conceptual relations, as an implementation of a model of the mental lexicon. The database, called WordNet, was organized around the notion of a synset between which semantic relations are expressed. A synset is a set of words with the same part-of-speech that can be interchanged in a certain context. For example, {car; ...

Meaningful language use rests on the grounding of the language in the nonlinguistic world and in the practices of language users. This grounding is built up and maintained in interaction, through Conversational Grounding, which is the interactive process with which interlocutors build mutual understanding; Justification, the ability to explain and provide reasons for one’s language use; and Ada...

One kind of semantic web service composition method based on description logic (DL) rule is introduced in this paper. We use DL rule to figure out the hyponymy relationship between concepts in domain ontology and model web service functional semantic of ServiceProfile, and define service DL rule (R1, R2 and R3) corresponding to sequence, split and join composition structure of GroundProfile res...

This paper describes conceptual semantic relations obtained from OpenLogos resources converted into NooJ format. These relations were symbolically represented in the OpenLogos lexicon as a taxonomic scheme called semantico-syntactic abstraction language (SAL), used to generate hierarchical hyponymy and hypernymy relations. The paper also describes action-of, result-of, and synonymy relations be...

We address the problem of automatic classification of associative and semantic relations between words, and particularly those that hold between nouns. Lexical relations such as synonymy, hypernymy/hyponymy, constitute the fundamental types of semantic relations. Associative relations are harder to define, since they include a long list of diverse relations, e.g., “Cause-Effect”, “Instrument-Ag...

As part of a project to construct an interactive program which will encourage children to play with language by building jokes, we have developed a large lexical database, closely based on WordNet. As well as the standard WordNet information about part of speech, synonymy, hyponymy, etc, we have added phonetic representations and symbolic links allowing attachment of pictures. All information i...
