Semantic parsing, the task of mapping utterances to semantic representations (e.g. logical forms), has its roots in the early natural language understanding systems of the 1960s. These rule-based systems were representationally sophisticated, but brittle, and thus fell out of favor as the statistical revolution swept NLP. Since the late 1990s, however, there has been a resurgence of interest in semantic parsing from the statistical perspective, where the representations are logical but the learning is not. Most recently, there are efforts to learn these logical forms automatically from denotations, a much more realistic but also challenging setting. The learning perspective has both led to practical large-scale semantic parsers, but interestingly also has implications for the semantic representations.
All PRELIM Seminars will be held in Room S9, 1st Floor.
