How Latent Semantic Analytics Transforms Big Data
Blog post from Sigma
Latent Semantic Analysis (LSA) is a powerful tool for extracting meaning from large volumes of unstructured text data by identifying relationships between words beyond simple keyword matching. Unlike traditional text analysis methods that rely on exact word matches and often miss context or synonyms, LSA uses mathematical modeling, particularly singular value decomposition (SVD), to capture deeper connections and nuances by examining word co-occurrence. This allows LSA to improve search results, sentiment analysis, support ticket triage, document classification, and fraud detection by understanding patterns and themes within the text. However, LSA faces challenges such as difficulty in explaining its process, handling language ambiguity, computational demands, and the need for proper data preparation. Despite these limitations, its future in big data analytics is promising, with potential enhancements through integration with neural networks and advancements in computational resources, enabling more scalable and interpretable applications.
