TAILIEUCHUNG - Báo cáo khoa học: "A Memory-Based Approach to the Treatment of Serial Verb Construction in Combinatory Categorial Grammar"

CCG, one of the most prominent grammar frameworks, efficiently deals with deletion under coordination in natural languages. However, when we expand our attention to more analytic languages whose degree of pro-dropping is more free, CCG’s decomposition rule for dealing with gapping becomes incapable of parsing some patterns of intra-sentential ellipses in serial verb construction. Moreover, the decomposition rule might also lead us to overgeneration problem. In this paper the composition rule is replaced by the use of memory mechanism, called CCG-MM. . | A Memory-Based Approach to the Treatment of Serial Verb Construction in Combinatory Categorial Grammar Prachya Boonkwan f School of Informatics ị National Electronics University of Edinburgh 10 Crichton Street and Computer Technology Center 112 Phahon Yothin Rd.

However when we expand our attention to more analytic languages whose degree of pro-dropping is more free CCG s decomposition rule for dealing with gapping becomes incapable of parsing some patterns of intra-sentential ellipses in serial verb construction. Moreover the decomposition rule might also lead us to overgeneration problem. In this paper the composition rule is replaced by the use of memory mechanism called CCG-MM. Fillers can be memorized and gaps can be induced from an input sentence in functional application rules while fillers and gaps are associated in coordination and serialization. Multimodal slashes which allow or ban memory operations are utilized for ease of resource management. As a result CCG-MM is more powerful than canonical CCG but its generative power can be bounded by partially linear indexed grammar. 1 Introduction Combinatory Categorial Grammar CCG Steedman 2000 is a prominent categorial grammar framework. Having a strong degree of lexical-ism Baldridge and Kruijff 2003 its grammars are encoded in terms of lexicons that is each lexicon is assigned with syntactic categories which dictate the syntactic derivation. One of its striking features is the combinatory operations that allow coordination of incomplete constituents. CCG is nearly context-free yet powerful enough for natural languages as it as well as TAG LIG and HG exhibits the lowest generative power in the mildly context-sensitive grammar class Vijay-Shanker and Weir 1994 . CCG accounts for gapping in natural .
