Peter Wiemer-Hastings of DePaul University will give the following talk on Wednesday, September 22.
================================================================= Title: >From Tutoring to Turing: Latent Semantic Analysis as Cognitive Model and Budget Natural Language Understanding Abstract: This talk will center on Latent Semantic Analysis (LSA), a vector-based technique for representing and comparing texts. Following a brief history of LSA and description of the process by which its representations are built, LSA will be discussed as a model for human language learning and representation. Despite the fact that it ignores syntax altogether, LSA has neared or matched human performance on a variety of tasks. For single-sentence texts, however, LSA does not perform well, presumably due (at least in part) to its ignorance of syntax. Recent research has explored methods for augmenting LSA with various types of structural knowledge. This work parallels psychological studies on the effects of structure on similarity judgments. The talk will conclude with descriptions of applications of LSA as an expectation-based natural language understanding mechanism. ------------------------ Yahoo!
