This paper proposes a novel approach to find sentiments at several granular levels ( paragraph, sentence, phrase, word ) in a document. It introduces a single [[UsesMethod::structured model]] for classifying text sentiment at these levels. There are various applications of sentiment classification at different levels of granularity.

This paper proposes a novel approach to finding sentiments at several granular levels (document, paragraph, sentence, phrase, word ). This paper introduces a single [[UsesMethod::structured model]] that transforms the multi-level sentiment classification task into a a single problem of learning from sequence of granular components using constrained [[UsesMethod::viterbi]]. Single model approach performs better than models trained in isolation for a given level of granularity. It considers two important ideas in modelling, firstly, higher level classification can benefit from granular level classification and secondly, granular level classification can benefit from higher level classification.

Structured Models for Fine-to-Coarse Sentiment Analysis

Summary

This paper proposes a novel approach to finding sentiments at several granular levels (document, paragraph, sentence, phrase, word ). This paper introduces a single structured model that transforms the multi-level sentiment classification task into a a single problem of learning from sequence of granular components using constrained viterbi. Single model approach performs better than models trained in isolation for a given level of granularity. It considers two important ideas in modelling, firstly, higher level classification can benefit from granular level classification and secondly, granular level classification can benefit from higher level classification.
