This paper describes a reader-based experiment on lexical cohesion, detailing the task given to readers and the analysis of the experimental data. We conclude with discussion of the usefulness of the data in future research on lexical cohesion. Cohesive ties between items in a text draw on the resources of a language to build up the text’s unity (Halliday and Hasan, 1976). Lexical cohesive ties draw on the lexicon, . word meanings. Sometimes the relation between the members of a tie is easy to identify, like near-synonymy (disease/illness), complementarity (boy/girl), whole-topart (box/lid), but the bulk of lexical cohesive texture. | Using Readers to Identify Lexical Cohesive Structures in Texts Beata Beigman Klebanov School of Computer Science and Engineering The Hebrew University of Jerusalem Jerusalem 91904 Israel beata@ Abstract This paper describes a reader-based experiment on lexical cohesion detailing the task given to readers and the analysis of the experimental data. We conclude with discussion of the usefulness of the data in future research on lexical cohesion. 1 Introduction The quest for finding what it is that makes an ordered list of linguistic forms into a text that is fluently readable by people dates back at least to Halliday and Hasan s 19 76 seminal work on textual cohesion. They identified a number of cohesive constructions repetition using the same words or via repeated reference substitution and ellipsis conjunction and lexical cohesion. Some of those structures - for example cohesion achieved through repeated reference - have been subjected to reader based tests often while trying to produce gold standard data for testing computational models a task requiring sufficient inter-annotator agreement Hirschman et al. 1998 Mitkov et al. 2000 Poesio and Vieira 1998 . Experimental investigation of lexical cohesion is an emerging enterprise Morris and Hirst 2005 to which the current study contributes. We present our version of the question to the reader to which lexical cohesion patterns are an answer section 2 describe an experiment on 22 readers using this question section 3 and analyze the experimental data section 4 . 2 From Lexical Cohesion to Anchoring Cohesive ties between items in a text draw on the resources of a language to build up the text s unity Halliday and Hasan 1976 .

Sometimes the relation between the members of a tie is easy to identify like near-synonymy dis-ease illness complementarity boy girl whole-topart box lid but the bulk of lexical cohesive texture is created by relations that
