Dialectic Feature-Based Fuzzy Graph Learning for Label Propagation Assisting Text Classification
Cherukula Madhu, M. Sudhakar · IEEE Transactions on Fuzzy Systems · 2024
The abundant deposits of unstructured and scarcely labeled data over social networks make text classification vital for structuring and extracting useful information. In addition, ig4 noring dialectal variations significantly hinders the performance of international English (especially American and British) text classification across numerous data domains. To address this multifaceted challenge, a comprehensive and adaptable frame8 work termed Dialectic Feature-based Fuzzy Graph Learning (DFFGL) is introduced that learns feature vectors by inculcating semantics and dialect variations from the inputted text. DFFGL then proficiently extracts uniquely modified terms frequency12 inverse document frequency, parts-of-speech-Tagged N-grams, with dialect-specific dictionary features in the fuzzy feature space to realize a novel language model. Later, these fuzzified features are affined by a novel fuzzy distance measure to construct an interpretable fuzzy graph that is then optimized using a novel elastic net regularizer for characterizing nodal relations, promis18 ing efficient classification through effective label propagation. Exhaustive F1-score evaluations on 6 English corpora and 17 diverse datasets reveal DFFGL's superiority in consistently registering over 93% and 80% in dialect identification and text classification even with just 10 labeled samples. Furthermore, DFFGL offers remarkable F1-score improvements of 10.2% and 17.3% over its peers in respective tasks, highlighting its extension to real-world data classification.
