a growing number of recent studies on verbal meaning have demonstrated that positing a direct mapping between (lexical/logical) semantics and syntax with respect to event structure can account for numerous linguistic phenomena. in this article, we demonstrate that certain facts in persian can only be explained by decomposing verbs into smaller syntactic pieces that reflect subparts of a complex...

Relationship acquisition has always contributed as an important enhancement to Natural Language Processing. Using “definition extraction” methods proved to be a very useful approach, not only for relationship extraction but also for enhancing the limited coverage of words in WordNet. It also played a major role in developing question answer systems and ontology learning for unrestricted data. V...

A novel constant tamper-proofing software watermark technique based on H encryption function is presented. First we split the watermark into smaller pieces before encoding them using CLOC scheme. With the watermark pieces, a many-to-one function (H function) as the decoding function is constructed in order to avoid the pattern-matching or reverse engineering attack. The results of the function ...

This chapter is concerned with how the ability of speakers and writers to produce syntactic structures is constrained by contextual and interactional factors. During language production we are often faced with a choice between syntactic alternatives. These syntactic alternatives are different in terms of their surface structure while being very similar in meaning, for example: an active versus ...

The existing search engines sometimes give unsatisfactory search result for lack of any categorization. If there is some means to know the preference of user about the search result and rank pages accordingly, the result will be more useful and accurate to the user. In the present paper a web page ranking algorithm is proposed based on syntactic classification of web pages. The proposed approac...

In this paper, we explore the syntactic relation patterns for opendomain factoid question answering. We propose a pattern extraction method to extract the various relations between the proper answers and different types of question words, including target words, head words, subject words and verbs, from syntactic trees. We further propose a QA-specific tree kernel to partially match the syntact...

Sublanguages are varieties of language that form "subsets" of the general language, typically exhibiting particular types of lexical, semantic, and other restrictions and deviance. SubCAT, the Sublanguage Corpus Analysis Toolkit, assesses the representativeness and closure properties of corpora to analyze the extent to which they are either sublanguages, or representative samples of the general...

A pattern deformational model is proposed in this paper. Pattern deformations are categorized into two types: local deformation and structural deformation. A structure-preserving local deformation can be decomposed into a syntactic deformation followed by a semantic deformation, the former being induced on primitive structures and the latter on primitive properties. Bayes error-correcting parsi...
