Since the early ages of artificial intelligence, associative or semantic networks have been proposed as representations that enable the storage of language units and the relationships that interconnect them, allowing for a variety of inference and reasoning processes, and simulating some of the functionalities of the human mind. The symbolic structures that emerge from these representations cor...

This paper describes a quantitative indicator for segmenting narrative text into coherent scenes. The indicator, called the lexical cohesion pro le (LCP), records lexical cohesiveness of words in a xed-length window moving word by word on the text. The cohesiveness of words, which represents their coherence, is computed by spreading activation on a semantic network. The basic idea of LCP is: (1...

We have developed a cohesive extraction based single document summarizer (COHSUM) based on coreference links in a document. The sentences providing the most references to other sentences and that other sentences are referring to, are considered the most important and are therefore extracted. Additionally, before evaluations of summary quality, a corpus analysis was performed on the original doc...

Clustering is the main technique for data analysis and it deals with the organisation of a set of objects in a multidimensional space into cohesive groups called clusters. Every cluster contains closely related objects and has very dissimilar objects in other clusters. Cluster analysis aims at discovering the objects with same behaviour in a collection. Thus, if an object satisfies a rule, the ...

Summaries automatically derived by sentence extraction are known to exhibit some coherence degradation, readability deterioration, and topical under-representation. We propose a strategy for improving upon these problems, aiming to generate more cohesive summaries by analyzing the lexical cohesion factors in the source document texts. As an initial experiment, we have looked at one particular f...

stylistics as a new method of text analysis explores the overall structure of texts. an author’s use of repetition as well as other linguistic and literary elements is among the most prominent stylistic features intended to create an effective expression. since the nahj al-balaghah is one of the most important religious books, and has a great literary value, it has always attracted the attentio...

My broad concern is with texts which aim to persuade an audience of a particular point of view on a particular topic – persuasion texts. Political speeches and newspaper editorials are examples of this text type. I put forward a strategy for critically engaging with such texts. Its focus is a persuasion text’s cohesion – how it is held together through its vocabulary and grammar. The strategy e...

We study some generalized notions of cohesiveness which arise naturally in connection with eeective versions of Ram-sey's Theorem. An innnite set A of natural numbers is n{cohesive (respectively, n{r{cohesive) if A is almost homogeneous for every computably enumerable (respectively, computable) 2{coloring of the n{element sets of natural numbers. (Thus the 1{cohesive and 1{r{cohesive sets coinc...
