New advances in corpus-based lexicography

  • A Hurskainen

Abstract

This article presents various approaches used in corpus-based computational lexico-graphy. A claim is made that in order for computational lexicography to be efficient, precise and comprehensive, it should utilize the method where the corpus text is first analysed, and the results of this analysis is then processed further to meet the needs of a dictionary. This method has several advantages, including high precision and recall, as well as the possibility to automate the process much further than with more traditional computational methods. The frequency list obtained by using the lemma (the equivalent of the headword) as basis helps in selecting the words to be in-cluded in the dictionary. The approach is demonstrated through various phases by applying SALAMA (the Swahili Language Manager) to the process. Manual work will be needed in the phase when examples of use are selected from the corpus, and possibly modified. However, the list of examples of use, arranged alphabetically according to the corresponding headword, can also be produced automatically. Thus the alphabetical list of headwords with examples of use is the mate-rial on which the lexicographer works manually. The article deals with problems encountered in compiling traditional printed dictionaries, and it excludes electronic dictionaries and thesauri. Keywords: lexicography, dictionary, language technology, computa-tional linguistics, automatic compilation, dictionary testing, informa-tion retrieval, morphological analysis, semantic analysis, disambigua-tion, heuristics
