“…Lexical cohesion analysis has been used in such NLP applications as determining the structure of text (Morris and Hirst, 1991) and automatic text summarization (Barzilay and Elhadad, 1999). In recent lexical cohesion research in linguistics (Hasan, 1984;Halliday and Hasan, 1989;Martin, 1992) non-classical relations are largely ignored, and the same is true in implementations of lexical cohesion in computational linguistics (Barzilay and Elhadad, 1999;Silber and McCoy, 2002), as the lexical resource used is WordNet. It is notable, however, that the original view of lexical semantic relations in the lexical cohesion work of Halliday and Hasan (1976) was very broad and general; the only criterion was that there had to be a recognizable relation between two words.…”
