The Automatic Acquisition Of Frequencies Of Verb Subcategorization Frames From Tagged Corpora
نویسندگان
چکیده
We describe a mechanism for automatically acquiring verb subcategorization frames and their frequencies in a large corpus. A tagged corpus is first partially parsed to identify noun phrases and then a finear grammar is used to estimate the appropriate subcategorization frame for each verb token in the corpus. In an experiment involving the identification of six fixed subcategorization frames, our current system showed more than 80% accuracy. In addition, a new statistical approach substantially improves the accuracy of the frequency estimation.

Unsupervised Acquisition of Verb Subcategorization Frames from Shallow-Parsed Corpora
In this paper, we reported experiments of unsupervised automatic acquisition of Italian and English verb subcategorization frames (SCFs) from general and domain corpora. The proposed technique operates on syntactically shallow-parsed corpora on the basis of a limited number of search heuristics not relying on any previous lexico-syntactic knowledge about SCFs. Although preliminary, reported res...

Learning Bayesian Belief Networks (BBN) from corpora and Support Vector Machines (SVM) have been applied to the automatic acquisition of verb subcategorization frames for Modern Greek. We are incorporating minimal linguistic resources, i.e. basic morphological tagging and phrase chunking, to demonstrate that verb subcategorization, which is of great significance for developing robust natural la...
متن کاملAutomatic Extraction of Subcategorization Frames from Spoken Corpora
We built a system for automatically extracting subcategorization frames (SCFs) from corpora of spoken language. The acquisition system, based on the design proposed by Briscoe & Carroll (1997) consists of a statistical parser, a SCF extractor, an English lemmatizer, and a SCF evaluator. These four components are applied in sequence to retrieve SCFs associated with each verb predicate in the cor...
متن کاملAcquiring 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 ...
