Distributional Semantics
Overview
Distributional semantics studies how patterns of word use reveal meaning, relationships between concepts, and changes in usage over time. It represents words and contexts with vector spaces, using methods such as word2vec, GloVe, PMI-based embeddings, and contextual language models; clustering, alignment, and distance measures are used to analyze senses and semantic change. These approaches are tested on tasks including word-sense induction, lexical semantic change, analogy, and prediction of human judgments and brain responses. They capture useful structure in language, but an ongoing tension is whether distributional associations amount to understanding or can distinguish semantic knowledge from correlations in text.
