The emergence of XML leads the development of applications centric XML-documents. Often the documents contain tagged paragraphs of natural language texts. The extraction of relevant data from paragraphs confronts with their irregular structure hidden in the text and requires powerful extraction patterns. Although a large spectrum of wrappers has been conceived to mainly process HTML pages, the ...

This study aimed at investigating the types of writing tasks produced by Saudi EFL learners. It also exploring challenges encountered those students. The sample this consists (261) students enrolled in ENG (011). were randomly chosen from three different colleges: college business, medicine, and engineering. researcher used a questionnaire with (13) items asking about faced during tasks. result...

1. Introduction Over the last decade, the research goals in natural language generation have shi fred fi'om the generation of isolated sentences to the production of coherent multi-sentence paragraphs. Two major aspects of the generation process have been focused on: deciding 'what to say' (the strategic level) and deciding 'how to say it' (the tactical level). In 1985, McKeown designed one of ...

We discuss an automatic method for the construction of hypertext links within and between newspaper articles. The method comprises three steps: determining the lexical chains in a text, building links between the paragraphs of articles, and building links between articles. Lexical chains capture the semantic relations between words that occur throughout a text. Each chain is a set of related wo...

Finding answers to why-questions involves finding arguments in texts, rather than the noun phrases that are typical targets for factoid questions. Detecting arguments requires detecting specific rhetorical structures and relations. Therefore, we proposed the use of Rhetorical Structure Theory (RST) as a tool for discovering answer to why-questions in paragraphs that are likely to contain the an...

Forensic linguistics and stylometry have in the exploration of linguistic patterns one their fundamental tools. Mathematical structures such as complex multilayer networks hypergraphs provide remarkable resources to represent analyze texts. In this paper, we present a model that includes some specific mesoscopic relations between different types words corpus (lexical words, verbs, linking other...
