PhonSenticNet: A Cognitive Approach to Microtext Normalization for Concept-Level Sentiment Analysis
This addresses performance issues in sentiment analysis for social media users by improving microtext handling, though it is incremental as it builds on existing normalization methods.
The paper tackled the problem of microtext normalization for concept-level sentiment analysis by coupling phonetic and symbolic AI to transform out-of-vocabulary concepts into standard forms, resulting in a 6% increase in polarity detection accuracy.
With the current upsurge in the usage of social media platforms, the trend of using short text (microtext) in place of standard words has seen a significant rise. The usage of microtext poses a considerable performance issue in concept-level sentiment analysis, since models are trained on standard words. This paper discusses the impact of coupling sub-symbolic (phonetics) with symbolic (machine learning) Artificial Intelligence to transform the out-of-vocabulary concepts into their standard in-vocabulary form. The phonetic distance is calculated using the Sorensen similarity algorithm. The phonetically similar invocabulary concepts thus obtained are then used to compute the correct polarity value, which was previously being miscalculated because of the presence of microtext. Our proposed framework increases the accuracy of polarity detection by 6% as compared to the earlier model. This also validates the fact that microtext normalization is a necessary pre-requisite for the sentiment analysis task.
