with the emphasis of minimalist program on functional categories as having an equal  or more prominent status than  lexical ones, decision on the nature of the categories has attracted more investigations in recent studies. one of the basic categories the presence of which beside other lexical categories of verb, noun and adjective has been in question, is preposition. it seems that the functio...

According to the dominant view in cognitive science, language processing requires perceptual simulation of symbols. Various experiments have shown that words that share a perceptual relationship are processed faster. We have proposed an alternative view in which perceptual cues are encoded in language. However, experiments supporting perceptual simulation or language statistics have focused on ...

Over the past couple of decades, it has been repeatedly investigated whether open-class items are processed in a different way from closed-class items. Most studies, however, have been bedeviled by difficulties in controlling all relevant distinctions between openand closed-class items. For example, whereas openclass items have a relatively low frequency of occurrence, closedclass words have a ...

The method of lexical chains is the first time introduced to generate summaries from Chinese texts. The algorithm which computes lexical chains based on the HowNet knowledge database is modified to improve the performance and suit Chinese summarization. Moreover, the construction rules of lexical chains are extended, and relationship among more lexical items is used. The algorithm constructs le...

In this paper we present BabelDomains, a unified resource which provides lexical items with information about domains of knowledge. We propose an automatic method that uses knowledge from various lexical resources, exploiting both distributional and graph-based clues, to accurately propagate domain information. We evaluate our methodology intrinsically on two lexical resources (WordNet and Babe...

This paper proposes an algorithm for causality inference based on a set of lexical knowledge bases that contain information about such items as event role, is-a hierarchy, relevant relation, antonymy, and other features. These lexical knowledge bases have mainly made use of lexical features and symbols in HowNet. Several types of questions are experimented to test the effectiveness of the algor...
