Abstract

Most advanced mobile applications require server-based and communication. This often causes additional energy consumption on the already energy-limited mobile devices. In this work, we provide to address these limitations on the mobile for Opinion Mining in Arabic. Instead of relying on compute-intensive NLP processing, the method uses an Arabic lexical resource stored on the device. Text is stemmed, and the words are then matched to our own developed ArSenL. ArSenL is the first publicly available large scale Standard Arabic sentiment lexicon (ArSenL) developed using a combination of English SentiWordnet (ESWN), Arabic WordNet, and the Arabic Morphological Analyzer (AraMorph). The scores from the matched stems are then processed through a classifier for determining the polarity. The method was tested on a published set of Arabic tweets, and an average accuracy of 67% was achieved. The developed mobile application is also made publicly available. The application takes as input a topic of interest and retrieves the latest Arabic tweets related to this topic. It then displays the tweets superimposed with colors representing sentiment labels as positive, negative or neutral. The application also provides visual summaries of searched topics and a history showing how the sentiments for a certain topic have been evolving.

Highlights

  • With the growth of social media and online blogs, people express their opinion and sentiment freely by providing product reviews, as well as comments about celebrities, and political and global events

  • Most opinion mining approaches in English are based on SentiWordNet (ESWN) (Esuli and Sebastiani, 2006; Baccianella & al., 2010) for extracting word-level sentiment polarity

  • Special interest has been given to opinion mining from Arabic texts, and as a result, there has been interest in developing Arabic lexicons for word-level sentiment evaluation

Summary

Introduction

With the growth of social media and online blogs, people express their opinion and sentiment freely by providing product reviews, as well as comments about celebrities, and political and global events. Special interest has been given to opinion mining from Arabic texts, and as a result, there has been interest in developing Arabic lexicons for word-level sentiment evaluation. In this work, we propose a method for opinion mining of Arabic tweets on mobile devices without the need for reliance on computeintensive NLP tools. One should use NLP tools to process text and produce lemmas that can be matched to ArsenL. To keep processing light on the mobile, we produce a stemmed version of ArSenL, and use word stems for matching. This design reduces the energy and performance costs caused by input/output and transmission operations on the mobile.
