Automatically identifying the source words of lexical blends in english
Computational Linguistics
Hi-index | 0.00 |
This paper describes strategies for automatic recognition of unknown variants of known words in a natural language processing system. The types of lexical variants which are detectable include inflexional aberrations, ad hoc abbreviations and spelling/typographical errors. This technique is independent of any particular grammar or parsing formalism, and can be implemented as a lexical lookup routine which heuristically prunes and orders the list of possible fixes found in the lexicon, then allowing the parser to treat the list of candidates as a set of multiple meanings for a polysemous word.
