Explore the fundamental concepts and applications of semantic lexicons and semantic tagging in this comprehensive lecture delivered by renowned computational linguist Nicoletta Calzolari. Delve into the theoretical foundations of semantic lexicons, understanding how they serve as structured repositories of word meanings and semantic relationships that enable machines to process natural language more effectively. Learn about the construction, organization, and utilization of semantic lexicons in various natural language processing tasks, including their role in disambiguating word meanings and establishing semantic connections between terms. Examine the principles and methodologies behind semantic tagging, discovering how this process assigns semantic labels to words and phrases to enhance computational understanding of text. Investigate practical applications of these technologies in machine translation, information retrieval, text analysis, and other language processing systems. Gain insights into current research trends, challenges, and future directions in the field of computational semantics, drawing from Calzolari's extensive expertise in lexical resources and language technology development.
