Abstract

People nowadays prefer sharing their opinions towards various products and services frequently on social networking sites (SNSs). These online reviews are huge in size and act as a goldmine for organizations to understand and monitor public reviews of their products and services. But these online reviews are highly unstructured in nature due to the presence of various linguistic features like hashtags, URLs, misspelled words, emoticons and many more. This highly unstructured data makes sentiment classification a challenging task. Hence, data pre-processing is an underlying and fundamental step in sentiment analysis. In the present work, authors have rigorously explored a series of pre-processing steps and observed that the sequence order of pre-processing steps affects the overall results. Hence, a sequence order of pre-processing steps has been proposed and implemented on two different social networks - Twitter and Google+. Twitter has been selected because of its tremendous popularity among netizens and Google+ has been selected because the domain of data for the proposed approach closely matches with the users’ interests on Google+. As the existing approach for handling data on Twitter cannot be implemented directly to handle Google+ data, a modified approach for Google+ has been suggested and implemented by the authors. In addition, some new dictionaries for handling linguistic features have been compiled and existing dictionaries have also been modified to improve pre-processing results. The proposed approach is implemented to evaluate the overall results.
