one of the most important and brilliant aspects in each language is the collocation that finally add up to lexical coherence . coming together in semantics considers as one of the semantic relationships at lexical level that appears at all languages , and doesnt specialize for a certain language . mean while .the study of pre-islamic period poem about coming together is a significant affair . t...

This paper presents an investigation of lexical chaining (Morris and Hirst, 1991) for measuring discourse coherence quality in test-taker essays. We hypothesize that attributes of lexical chains, as well as interactions between lexical chains and explicit discourse elements, can be harnessed for representing coherence. Our experiments reveal that performance achieved by our new lexical chain fe...

Coherence is established by semantic connections between sentences of a text which can be modeled by lexical relations. In this paper, we introduce the lexical coherence graph (LCG), a new graph-based model to represent lexical relations among sentences. The frequency of subgraphs (coherence patterns) of this graph captures the connectivity style of sentence nodes in this graph. The coherence o...

This paper presents research that connects the cohesion structure of a text to the derivation of its coherence structure. Two diierent algorithms that derive the cohesion structure in the form of lexical paths from large thesauri are illustrated. Their results are correlated with (1) cue phrases of discourse usage and (2) coherence constraints empirically derived. A novel model of coherence str...

textual coherence in cloudy semantic relations through which the relation is each piece of speech or writing acts as context. ma.k holliday and r.hassan played a key ale estabhshing the relationship in contchal shachre and the relationship among sentence elements. the believe that coherence applies to all kids of relations which link one element of the sentence to the element in previous senten...

Anomic aphasia is a disturbance affecting lexical retrieval. Nonetheless, persons with this disorder may also experience difficulties in the construction of coherent narratives. Whether this symptom is a sign of a macrolinguistic difficulty per se or reflects the lexical disorder is still an open debate. In order to analyze the effect of the lexical impairment on macrolinguistic processing, we ...

It is a widely accepted fact that coherence enables a text’s comprehensibility. A major source of coherence is discourse cohesion (textual properties of the text). Lexical cohesion (e.g. synonymy) and discourse connectives are two major types of discourse cohesion. We investigate the contribution of these two types of cohesion to the overall comprehension of bi-clausal sentences in Turkish. In ...

Both notional and grammatical number affect agreement during language production. To explore their workings, we investigated how semantic integration, a type of conceptual relatedness, produces variations in agreement (Solomon & Pearlmutter, 2004). These agreement variations are open to competing notional and lexical-grammatical number accounts. The notional hypothesis is that changes in number...

This article outlines a quantitative method for segmenting texts into thematically coherent units. This method relies on a network of lexical collocations to compute the thematic coherence of the different parts of a text from the lexical cohesiveness of their words. We also present the results of an experiment about locating boundaries between a series of concatened texts. 1 I n t r o d u c t ...

Text summarization addresses both the problem of selecting the most important portions of text and the problem of generating coherent summaries. We present in this paper the summarizer of the University of Lethbridge at DUC 2001, which is based on an efficient use of lexical chains.
