Keynote Talk

Linguistic Problems in Computational Linguistics

Computational linguistics constructs computational models of natural language. But how is it related to traditional linguistic problems, which a linguist would like to solve? In this talk, we discuss various linguistic problems, which find solutions in computational linguistics (or do not find). The methods can be algorithmic, traditional machine learning or deep learning. For example, for each level of language analysis, we consider various problems. At morphological level, word segmentation, grammar theory, POS tagging. At syntactic level, parsing, grammar rules. At semantic level, paraphrasis (semantic similarity), lexical relations, word sense disambiguation, dictionary analysis and construction, definition construction. At pragmatic level, truth conditions. At discourse level, anaphora resolution, authorship attribution, stylistic analysis, humor detection, joke generation, sentiment and emotion analysis, gender and age detection, hate/offensive/hope speech, medical conditions (like depression). At creative level, prediction of success of novels, poetry generation, genre detection, plot generation.
