!513 Disunity in Cohesion: How Purpose Affects Methods and Results When Analyzing Lexical Cohesion

Lexical Cohesion is a commonly studied lin-guistic feature as it is easily identified from the surface of a text. However, the purposes for studying lexical cohesion are varied, and each purpose requires different methods. This study analyzes two short movie review texts for four different research purposes using lex-ical cohesion: text evaluation, text segmenta-tion, text summarization, and text criticism. The analysis shows that these four different purposes produce very different results con-cerning the lexical cohesion of the two texts, suggesting that the apparently straightforward construct of lexical cohesion is actually com-plex.
