....proximity expressed by WordNet s links, and a poor algorithm for chaining. Over chaining the linking of two poorly related words might happen whenever two semantically distant words are close to each other in WordNet s graph. Over chaining often results in the merging of two chains. Barzilay [2] uses lexical chains in texts for summarization. Summarization proceeds in three steps: the original text is rst segmented, lexical chains are then constructed, strong chains are identi ed and signi cant sentences are extracted from text. This algorithm relies heavily on WordNet as a lexical ....

....needs in a more effective and efficient way. In this paper, a sentence based extraction summarization system which takes in a single document from any domain was developed to produce an indicative summary as output. The approach taken was initially similar to that taken by Barzilay and Elhadad [1]. It is based on the use of lexical chains, which can be computed without requiring deep text understanding while can still be able to determine the context of the text at the same time. However, different to Barzilay and Elhadad, except the semantic relatedness of words in the text was ....
....term repetition to construct a weighted graph with nodes being the paragraphs and the weighted arcs representing the similarity between them. Another class of this cohesion based system is the use of lexical chain, whose concept was first introduced by Morris and Hirst [31] Barzilay and Elhadad [1] explored the use of lexical chains and used WordNet as their knowledge base. They claimed that by using lexical chains, the readers will be able to get a better indication of the topic of the text compared to simply picking the most frequent words in the text (i.e. frequency based) In their ....

....work In text summarization, it is a standard approach to select sentences from the original text for the summary based on characteristic words [10] Such words and ways to find them are of special interest here. One approach is to use lexical knowledge from sources such as WORDNET [11] compare [2]. Another is to use statistical information gathered from a corpus [1] A well known measure that relies only on the given text collection is Tf Idf (used, for example, in [3, 4] which measures how characteristic a word is for its text. Considering domain specific summarization, words that are ....

....by ideas in the original document will allow to increase the similarities between sentences for the headline based algorithm for sentence selection. Note that tracking the words coupled with each idea in the sequence will yield the thread of an idea, similar to the lexical chains described in [2]. Two options are preferred to train the Hidden Markov model: 1. Estimate a Hidden Markov Model from a set of documents parsed as sequences of known words. This may be achieved through the EM algorithm. 2. Learn both the structure of the Hidden Markov Model and its parameters. By either ....

.... text rather than vast quantities of semi relevant documents [1] Summarisation is another task that can be greatly improved by well segmented text since the aim of this task is to identify pertinent subtopics in a document and then generate a summary, which encapsulates all of these subtopics [2]. The main motivation of our research is to investigate whether our lexical chaining technique can be used to segment television news shows into distinct new stories. Lexical chaining is a linguistic technique that uses an auxiliary resource (in our case the WordNet online thesaurus [3] to ....

....intersection parameters for more verbose output and rank the different themes. This ranking is based on theme size, similarity score and significance. The first two of these scores are produced by the similarity component, and the significance score of the theme is computed using lexical chains [Barzilay and Elhadad 1997], as the sum of lexical chain scores of theme sentences computed from the text in which a sentence originally belongs. Lexical chains, sequences of semantically related words, are tightly connected to the lexical cohe sive structure of the text and have been shown to be useful for determining ....
