Research Interests: ~

My research interests include the cognitive processes involved in comprehension and appreciation of figurative language, especially metaphor and irony. Concerning metaphor comprehension, I have proposed the interpretive diversity theory which argues that interpretively more diverse metaphors are easier to comprehend via a categorization process, and thus less diverse metaphors fail to be processed as categorizations and reinterpreted as comparisons. I have shown the superiority of the interpretive diversity theory over the other metaphor theories both psychologically and computationally (Utsumi,2006a,2007a; Utsumi & Kuwabara,2005). Recently, I and my colleague Dr. Maki Sakamoto (The University of Electro-Communications) have proposed the two-stage categorization theory which argues that adjective metaphors (e.g., red voice) and predicative metaphors (e.g., The rumor flew through the office) are comprehended via a two-stage categorization process (Utsumi & Sakamoto, 2007a, 2007b). I have also examined the process of metaphor appreciation, in particular to what degree poetic appreciation of metaphors can be explained by the mechanism of incongruity resolution and what other processes are involved in poetic appreciation (Utsumi,2003; Utsumi,2005). For irony comprehension, I have proposed the implicit display theory (Utsumi,2000,2007b) as a comprehensive theory of irony. According to the implicit display theory, verbal irony is an utterance that implicitly displays ironic environment, a proper situational setting in the discourse context. The implicit display theory is one of the leading theories in irony research.

Furthermore, I have recently started a research project of cognitive rhetoric that aims at empirically exploring a cognitive mechanism underlying the relationship between styles, meanings and effects, especially focusing on rhetorical figures (Utsumi,2002,2006b). I and my colleague Akihito Kanai (Hosei University) have been editing a special issue ``cognitive science of rhetoric'' in the journal of Cognitive Studies, the official journal of the Japanese Cognitive Science Society.

I am also interested in geometric models of word meanings, especially a vector space model of word meanings such as latent semantic analysis (LSA). I and my students have started a research project that explores semantic properties of different word vectors constructed by different methods and develops a new method for constructing word vectors. Our preliminary result is presented in Utsumi & Suzuki(2006). I have also tried to simulate cognitive processes involved in metaphor comprehension using word vectors and tested several competing theories of metaphor comprehension (Utsumi,2006a; Utsumi & Sakamoto,2007a, 2007b).

My other research interest lies in several issues in Web engineering and natural language processing. In particular, I and my students have been engaged in automatic summarization and its application to information retrieval, document clustering, automatic estimation of Web credibility and other Web retrieval support methods.
