Exploring Automatic Theme Identification: A Rule-Based Approach.
Konferenzveröffentlichung, Bibliographie
Kurzbeschreibung (Abstract)
Knowledge about Theme-Rheme serves the interpretation of a text in terms of its thematic progression and provides a window into the topicality of a text as well as text type (genre). This is potentially relevant for NLP tasks such as information extraction and text clas- sification. To explore this potential, large corpora annotated for Theme-Rheme organization are needed. We report on a rule-based system for the automatic identification of Theme to be employed for corpus annotation. The rules are manually derived from a set of sentences parsed syntactically with the Stanford parser and analyzed in terms of Theme on the basis of Systemic Functional Grammar (SFG). We describe the development of the rule set and the automatic procedure of Theme identification and assess the validity of the approach by application to some authentic text data.
