In order to guide a knowledge engineer in the design of ontologies, CGKAT (Martin, 1995), our knowledge acquisition tool, exploits the terminological knowledge base WordNet. Since the top-level concept types of this large general ontology are poorly structured, we subordinated/merged them into an extension of the top-level ontology adviced by Sowa (1992). The result is proposed in the initial c...
Graph-based similarity over WordNet has been previously shown to perform very well on word similarity. This paper presents a study of the performance of such a graph-based algorithm when using different relations and versions of Wordnet. The graph algorithm is based on Personalized PageRank, a random-walk based algorithm which computes the probability of a random-walk initiated in the target wo...
This paper introduces a Korean-Chinese-Japanese wordnet for nouns, verbs and adjectives. This wordnet is constructed based on a hierarchy of shared semantic categories originated from NTT Goidaikei (Hierarchical Lexical System). The Korean wordnet has been constructed by mapping a semantic category to each Korean word sense in a way that maps the same semantic hierarchy to the meanings of nouns...
Metonymy is a creative process that establishes relationships based on contiguity or semantic relatedness between concepts. We outline a mechanism for deriving new concepts from WordNet using metonymy. We argue that by exploiting polysemy in WordNet we can take advantage of the metonymic relations between concepts. The focus of our metonymy generation work has been the creation of nounnoun comp...
Representations in WordNet are not on the level of individual words or word forms, but on the level of word meanings (lexemes). A word meaning, in turn, is characterized by simply listing the word forms that can be used to express it in a synonym set (synset). As a result, the meaning a word in WordNet is determined by its sets of synonyms. This is essentially a recursive definition of word mea...
WoNeF, an improved, extended and evaluated automatic French translation of WordNet Identifying the various possible meanings of each word of the vocabulary is a difficult problem that requires a lot of manual work. It has been tackled by the WordNet lexical semantics database in English, but there are still few resources available for other languages. Automatic translations of WordNet have been...
In this paper we present a linguistic resource for the lexical representation of affective knowledge. This resource (named WORDNETAFFECT) was developed starting from WORDNET, through a selection and tagging of a subset of synsets representing the affective
We have created an information extraction system that allows users to train the system on a domain of interest. The system helps to maximize the effect of user training by applying WordNet to rule generation and validation. The results show that, with careful control, WordNet is helpful in generating useful rules to cover more instances and hence improve the overall performance. This is particu...
In this paper, I demonstrate that verbs can be disambiguated according to aspect by rules that exam° hue the WordNet category of the direct object. First, when evaluated over a corpus of medical reports, I show that WordNet categories correlate with aspectual class. Then, I develop a rule for distinguishing between stative and event occurrences of have by the WordNet category of the direct obje...
We examine the strategies of organizing terminological information in WordNet, and describe an analogous strategy of adding terminological senses of lexical units to plWordNet, a large Polish wordnet. Wordnet builders must cope with differences in lexical and terminological definitions of a term, and with the boundaries between terminological and lexical information. A somewhat adjusted strateg...
