Acquiring Verb Subcategorization Frames in Bengali from Corpora

Subcategorization frames acquisition of a phrase can be described as a mechanism to extract different types of relevant arguments that are associated with that phrase in a sentence. This paper presents the acquisition of different subcategory frames for a specific Bengali verb that has been identified from POS tagged and chunked data prepared from raw Bengali news corpus. Syntax plays the main role in the acquisition process and not the semantics like thematic roles. The output frames of the verb have been compared with the frames of its English verb that has been identified using bilingual lexicon. The frames for the English verb have been extracted using Verbnet. This system has demonstrated precision and recall values of 85.21% and 83.94% respectively on a test set of 1500 sentences.
