ABSTRACT - Lexical anomalies are viewed as choices of lexical items in context violating certain contextual restrictions. The notion can be effectively applied to measuring syntagmatic association strength in compositions, analyzing lexical errors by native speakers and L2-learners, and figurative language constructions, especially conceptual metaphor. State-of-the-art semantic models, i.e. word- embeddings, present strong and simple techniques for semantic analysis of syntagmatic (collocations) and paradigmatic (synonyms, semantic regularities) relations. The talk covers recent advances in applying word-embeddings to association strength measurement, detection and interpretation of lexical errors in Russian, and metaphorical expressions in English.
