Using Semantically Motivated Estimates to Help Subcategorization Acquisition
Research into the automatic acquisition of subcategorization frames from corpora is starting to produce large-scale computational lexicons which include valuable frequency information. However, the accuracy of the resulting lexicons shows room for improvement. One source of error lies in the lack of accurate back-off estimates for subcategorization frames, delimiting the performance of statisti...
متن کاملSubcategorization acquisition
Manual development of large subcategorised lexicons has proved difficult because predicates change behaviour between sublanguages, domains and over time. Yet access to a comprehensive subcategorization lexicon is vital for successful parsing capable of recovering predicate-argument relations, and probabilistic parsers would greatly benefit from accurate information concerning the relative likel...
متن کاملClustering Polysemic Subcategorization Frame Distributions Semantically
Previous research has demonstrated the utility of clustering in inducing semantic verb classes from undisambiguated corpus data. We describe a new approach which involves clustering subcategorization frame (SCF) distributions using the Information Bottleneck and nearest neighbour methods. In contrast to previous work, we particularly focus on clustering polysemic verbs. A novel evaluation schem...
متن کاملSubcategorization Acquisition as an Evaluation Method for WSD
Evaluation of word sense disambiguation (WSD) systems is often based on machine-readable dictionaries (MRDs). Such evaluation typically employs a set of fine-grained dictionary senses and considers them all to be equally important. In this paper, we propose a novel evaluation method for WSD systems in the context of automatic subcategorization acquisition. Building on an extant subcategorizatio...
متن کاملBengali Verb Subcategorization Frame Acquisition - A Baseline Model
Acquisition of verb subcategorization frames is important as verbs generally take different types of relevant arguments associated with each phrase in a sentence in comparison to other parts of speech categories. This paper presents the acquisition of different subcategorization frames for a Bengali verb Kara (do). It generates compound verbs in Bengali when combined with various noun phrases. ...
