Taiwo Kolajo, Olawande Daramola, Ayodele Adebiyi, Seth Aaditeshwar

TL;DR
This paper introduces a pre-processing framework for social media feeds that leverages an integrated knowledge base and an adapted Lesk algorithm to improve semantic analysis, especially for slang and abbreviations, resulting in higher accuracy in sentiment extraction.
Contribution
The paper presents a novel framework combining local and online knowledge sources with an adapted Lesk algorithm for enhanced social media feed pre-processing.
Findings
Achieved 94.07% accuracy on standardized dataset
Achieved 99.78% accuracy on localised dataset
Outperformed existing methods across multiple machine learning models
Abstract
Most of the previous studies on the semantic analysis of social media feeds have not considered the issue of ambiguity that is associated with slangs, abbreviations, and acronyms that are embedded in social media posts. These noisy terms have implicit meanings and form part of the rich semantic context that must be analysed to gain complete insights from social media feeds. This paper proposes an improved framework for pre-processing of social media feeds for better performance. To do this, the use of an integrated knowledge base (ikb) which comprises a local knowledge source (Naijalingo), urban dictionary and internet slang was combined with the adapted Lesk algorithm to facilitate semantic analysis of social media feeds. Experimental results showed that the proposed approach performed better than existing methods when it was tested on three machine learning models, which are support…
