Situation entities (SEs) are the events, states, generic statements, and embedded facts and propositions introduced to a discourse by clauses of text. We report on the first datadriven models for labeling clauses according to the type of SE they introduce. SE classification is important for discourse mode identification and for tracking the temporal progression of a discourse. We show that (a) linguistically-motivated cooccurrence features and grammatical relation information from deep syntactic analysis improve classification accuracy and (b) using a sequencing model provides improvements over assigning labels based on the utterance alone. . | A Sequencing Model for Situation Entity Classification Alexis Palmer Elias Ponvert Jason Baldridge and Carlota Smith Department of Linguistics University of Texas at Austin alexispalmer ponvert jbaldrid carlotasmith @ Abstract Situation entities SEs are the events states generic statements and embedded facts and propositions introduced to a discourse by clauses of text. We report on the first data-driven models for labeling clauses according to the type of SE they introduce. SE classification is important for discourse mode identification and for tracking the temporal progression of a discourse. We show that a linguistically-motivated cooccurrence features and grammatical relation information from deep syntactic analysis improve classification accuracy and b using a sequencing model provides improvements over assigning labels based on the utterance alone. We report on genre effects which support the analysis of discourse modes having characteristic distributions and sequences of SEs. 1 Introduction Understanding discourse requires identifying the participants in the discourse the situations they participate in and the various relationships between and among both participants and situations. Coreference resolution for example is concerned with understanding the relationships between references to discourse participants. This paper addresses the problem of identifying and classifying references to situations expressed in written English texts. Situation entities SEs are the events states generic statements and embedded facts and propositions which clauses introduce Vendler 1967 896 Verkuyl 1972 Dowty 1979 Smith 1991 Asher 1993 Carlson and Pelletier 1995 . Consider the text passage below which introduces an event-type entity in 1 a report-type entity in 2 and a statetype entity in 3 . 1 Sony Corp. has heavily promoted the Video Walkman since the product s introduction last summer 2 but Bob Gerson video editor of This Week in Consumer Electronics says 3
