Book Description
The objective of this monograph is to improve the performance of the sentiment analysis model by incorporating the semantic, syntactic and common-sense knowledge. This book proposes a novel semantic concept extraction approach that uses dependency relations between words to extract the features from the text. Proposed approach combines the semantic and common-sense knowledge for the better understanding of the text. In addition, the book aims to extract prominent features from the unstructured text by eliminating the noisy, irrelevant and redundant features. Readers will also discover a proposed method for efficient dimensionality reduction to alleviate the data sparseness problem being faced by machine learning model. Authors pay attention to the four main findings of the book : -Performance of the sentiment analysis can be improved by reducing the redundancy among the features. Experimental results show that minimum Redundancy Maximum Relevance (mRMR) feature selection technique improves the performance of the sentiment analysis by eliminating the redundant features. - Boolean Multinomial Naive Bayes (BMNB) machine learning algorithm with mRMR feature selection technique performs better than Support Vector Machine (SVM) classifier for sentiment analysis. - The problem of data sparseness is alleviated by semantic clustering of features, which in turn improves the performance of the sentiment analysis. - Semantic relations among the words in the text have useful cues for sentiment analysis. Common-sense knowledge in form of ConceptNet ontology acquires knowledge, which provides a better understanding of the text that improves the performance of the sentiment analysis.

Book Description
Sentiment analysis, one of the trending natural language processing tasks, is used to mine opinions or sentiments from a given text. There are two significant challenges in sentiment analysis. The first challenge is the complexity in data pre-processing caused by the high dimensionality of textual data. The second is the uncertainty in classifying sentiment polarities due to the ambiguity of natural languages. Existing research may lack an efficient and straightforward solution to resolve the first issue; or discuss the trade-off between accuracy and coverage regarding uncertain data. To address these issues, we propose a model using part-of-speech-based feature extraction to reduce dimensionality and game-theoretic rough sets (GTRS) to analyze the accuracy and coverage trade-off. We evaluate this model with three different datasets, Yelp reviews, IMDB movie reviews, and Amazon product reviews. The experiment results show that the proposed model outperforms Pawlak's rough set model and 0.5-probabilistic rough set model. In comparison with the sentiment analysis tool Valence Aware Dictionary for Sentiment Reasoning (VADER) and four traditional binary classification models (i.e., SVM, na ̈ıve Bayes, decision tree, and KNN), the proposed model also achieves higher accuracy. This research suggests that the proposed model has achieved higher results of both accuracy and coverage, and is promising to deal with the complexity and uncertainty in sentiment analysis tasks.
