Coreference Resolution to Support IE from Indian Classical Music Forums

چکیده
Efficient music information retrieval (MIR) require to have meta information about music along with content based information in the knowledge base. Discussion forums on music are rich sources of information gathered from a wider audience. Taking into consideration the nature of text in these web resources, the yield of relation extraction is quite dependent on resolving the entity references in the document. Among the few music forums dealing with Indian classical music, rasikas.org (rasikas, 2015) having rich information about artistes, raga and other music concepts is taken for our study. The forum posts generally contain anaphoric references to the main topic of the thread or any other entity in the discourse. In this paper we focus on coreference resolution for short discourse noisy text like that of forum posts. Since grammatical roles capture relation between mentions in a discourse, those features extracted from dependency parsing are widely explored along with semantic compatibility feature. On investigation of issues, the need for integrating known dependencies between features emerged. A Bayesian network with predefined network structure is evaluated, since a Bayesian belief network enacts a probabilistic rule based system. To the extent possible the superior behaviour of Bayesian network over SVM is analysed.

Clustering step in the mention-pair paradigm for coreference resolution, forms the chain of coreferent mentions from the mention pairs classified as coreferent. Clustering methods including best-first clustering considers each antecedent candidate individually, while selecting the antecedent for an anaphoric mention. Here we introduce an easyto-implement modification to best-first clustering to...
متن کاملA Framework that Uses the Web for Named Entity Class Identification: Case Study for Indian Classical Music Forums
Identification of named entity(NE) class (semantic class) is crucial for NLP problems like coreference resolution where semantic compatibility between the entity mentions is imperative to coreference decision. Short and noisy text containing the entity makes it challenging to extract the NE class of the entity through the context. We introduce a framework for named entity class identification f...
متن کاملCorpus based coreference resolution for Farsi text
"Coreference resolution" or "finding all expressions that refer to the same entity" in a text, is one of the important requirements in natural language processing. Two words are coreference when both refer to a single entity in the text or the real world. So the main task of coreference resolution systems is to identify terms that refer to a unique entity. A coreference resolution tool could be...
