TAILIEUCHUNG - Báo cáo khoa học: "Creative Language Retrieval: A Robust Hybrid of Information Retrieval and Linguistic Creativity"

Information retrieval (IR) and figurative language processing (FLP) could scarcely be more different in their treatment of language and meaning. IR views language as an open-ended set of mostly stable signs with which texts can be indexed and retrieved, focusing more on a text’s potential relevance than its potential meaning. In contrast, FLP views language as a system of unstable signs that can be used to talk about the world in creative new ways. | Creative Language Retrieval A Robust Hybrid of Information Retrieval and Linguistic Creativity Tony Veale School of Computer Science and Informatics University College Dublin Belfield Dublin D4 Ireland. Abstract Information retrieval IR and figurative language processing FLP could scarcely be more different in their treatment of language and meaning. IR views language as an open-ended set of mostly stable signs with which texts can be indexed and retrieved focusing more on a text s potential relevance than its potential meaning. In contrast FLP views language as a system of unstable signs that can be used to talk about the world in creative new ways. There is another key difference IR is practical scalable and robust and in daily use by millions of casual users. FLP is neither scalable nor robust and not yet practical enough to migrate beyond the lab. This paper thus presents a mutually beneficial hybrid of IR and FLP one that enriches IR with new operators to enable the non-literal retrieval of creative expressions and which also transplants FLP into a robust scalable framework in which practical applications of linguistic creativity can be implemented. 1 Introduction Words should not always be taken at face value. Figurative devices like metaphor can communicate far richer meanings than are evident from a superficial - and perhaps literally nonsensical - reading. Figurative Language Processing FLP thus uses a variety of special mechanisms and representations 278 to assign non-literal meanings not just to metaphors but to similes analogies epithets puns and other creative uses of language see Martin 1990 Fass 1991 Way 1991 Indurkhya 1992 Fass 1997 Barnden 2006 Veale and Butnariu 2010 . Computationalists have explored heterodox solutions to the procedural and representational challenges of metaphor and FLP more generally ranging from flexible representations . the preference semantics of Wilks 1978 and the col-lative semantics of Fass 1991 1997
