presents the mechanism for query processing and retrieval with the measures used for the similarity analysis of the indexing structures. Section 6 describes an experiment conducted to evaluate the effectiveness of the proposed approach. Section 7 summarizes related work in the area of re-use systems. Section 8 concludes the paper with some remarks on planned experiments with the system and furt...

in this paper, we examine the treatment of persian relative clauses in role and reference grammar. rrg is a structural-functional theory which has studied the syntax-semantics-pragmatics interface in human language systems. the main objectives of this article, on the one hand, are to elucidate syntactic, semantic and pragmatic properties of farsi relative clauses, and on the other hand, to asse...

The PRC Adaptive Knowledge-based Text Understanding System (PAKTUS) was develope d as an Independent Research and Development project at PRC from 1984 through 1992 . It includes a core English lexicon and grammar, a concept network, processes for applying these to lexical , syntactic, semantic, and discourse analysis, and tools that support the adaptation of the generi c core to new domains, pr...

This paper addresses issues related to employing logic-based semantic composition as a meaning representation for Arabic within a unification-based syntax-semantics interface. Since semantic representation has to be compositional on the level of semantic processing λ-calculus based on Discourse Representation Theory can be utilized as a helpful and practical technique for the semantic construct...

The patterns of semantic errors in speaking and writing are used to constrain claims about the structure of lexical access mechanisms in speech and written language production. It is argued that it is not necessary to postulate a modality-neutral level of lexical representation (lemma) that is intermediate between lexical-semantic representations and modality-specific lexical representations. A...

The theory of lexical selection presented by Levelt, Roelofs & Meyer addresses the mechanisms of semantic activation that lead to the selection of isolated words. The theory does not appear to extend naturally to the referential use of words (particularly pronouns) in coherent discourse. A more complete theory of lexical selection has to consider the semantics of discourse as well as lexical se...

A proposal is presented for integration between a graphical model, such as conceptual maps, and ontologies codified in the OWL language. Conceptual maps are a flexible form of knowledge representation, very useful in education-related collaborative environments; OWL is a language of knowledge representation oriented to semantic analysis and processing carried out by machines. Integration consis...

Although distributional models of word meaning have been widely used in Information Retrieval achieving an effective representation and generalization schema of words in isolation, the composition of words in phrases or sentences is still a challenging task. Different methods have been proposed to account on syntactic structures to combine words in term of algebraic operators (e.g. tensor produ...
