Our goal is to identify the features that predict cue selection and placement in order to devise strategies for automatic text generation. Much previous work in this area has relied on ad hoc methods. Our coding scheme for the exhaustive analysis of discourse allows a systematic evaluation and refinement of hypotheses concerning cues. We report two results based on this analysis: a comparison of the distribution of Sn~CE and BECAUSEin our corpus, and the impact of embeddedness on cue selection. . | Investigating Cue Selection and Placement in Tutorial Discourse Megan Moser Learning Research Dev. Center and Department of Linguistics University of Pittsburgh Pittsburgh PA 15260 moser@. edu Abstract Our goal is to identify the features that predict cue selection and placement in order to devise strategies for automatic text generation. Much previous work in this area has relied on ad hoc methods. Our coding scheme for the exhaustive analysis of discourse allows a systematic evaluation and refinement of hypotheses concerning cues. We report two results based on this analysis a comparison of the distribution of SINCE and BECAUSE in our corpus and the impact of embeddedness on cue selection. Discourse cues play a crucial role in many discourse processing tasks including plan recognition Litman and Allen 1987 anaphora resolution Grosz and Sidner 1986 and generation of coherent multisentential texts Elhadad and McKeown 1990 Roesner and stede 1992 Scott and de Souza 1990 Zukerman 1990 . Cues are words or phrases such as BECAUSE FIRST ALTHOUGH and ALSO that mark structural and semantic relationships between discourse entities. While some specific issues concerning cue usage have been resolved . the disambiguation of discourse and sentential cues Hirschberg and Litman 1993 our concern is to identify general strategies of cue selection and placement that can be implemented for automatic text generation. Relevant research in reading comprehension presents a mixed picture Goldman and Murray 1992 Lorch 1989 suggesting that felicitous use of cues improves comprehension and recall but that indiscriminate use of cues may have detrimental effects on recall Millis et al. 1993 and that the benefit of cues may depend on the subjects reading skill and level of domain knowledge McNamara et al. In press . However interpreting the research is problematic because the manipulation of cues both within and across studies has been very unsystematic Lorch 1989 . While Knott and .
