Abstract

THE INCREASING GROWTH OF WEB HAS GIVEN PEOPLE THE ABILITY TO SIMPLY EXPRESS THEIR OPINION AND KNOW OTHERS’ OPINION. MINING VIEWPOINTS AND OPINION OR SENTIMENT ANALYSIS IS CONSIDERED AS A SUBFIELD OF TEXT MINING AND ITS MAIN GOAL IS TO FIND WRITER’S OPINION ABOUT A TOPIC. MEETING THIS GOAL IS NOT A SIMPLE TASK SINCE EMOTIONS IN A SENTENCE OR A PHRASE ARE USUALLY RECOGNIZED BY COMBINING EMOTIONS OF ITS WORDS. IN THIS PAPER, WE CONCENTRATE ON BIPOLAR TERMS WHICH ARE THOSE PHRASES CONTAINING AT LEAST ONE POSITIVE AND ONE NEGATIVE WORD. IN ORDER TO CONSIDER BIPOLAR TERMS, PHRASES WITH OPPOSING POLARITY ARE FIRST EXTRACTED FROM PERSENT DATASET THEN, BASED ON THE WORDS OF THESE PHRASES AND THEIR POLARITY IN THE SENTENCE THE FINAL SCORE IS COMPUTED. THEN, THE SCORE OF EACH SENTENCE IS CALCULATED USING CNRC LEXICON AND MAXIMUM OF ABSOLUTE VALUES, DIFFERENCE, AND AVERAGE METHODS WITH AND WITHOUT CONSIDERING BIPOLAR TERMS. THE RESULTS OF IMPLEMENTATION OF THE PROPOSED METHOD SHOW THAT EMPLOYING BIPOLAR TERMS IMPROVES THE LEXICON-BASED APPROACH FOR BOTH POLARITY DETECTION AND SCORE PREDICTION PROBLEMS.
