66 Belinda Maia– Find definition candidates and semantic relations aided by lists of lexical /syntacticpatterns (these tools function in several languages, but need furtherdevelopment).The lexical / phrasal databases allow one to search for regular expressions andconduct searches using the NooJ part-of-speech (POS) annotated dictionaries. Itis possible to mix lexical with POS data, and the objective in future is to teachpeople to create their own disambiguation grammars for their research using theNooJ system. 3At present the Corpógrafo provides the terminologist and the lexicographerwith the possibility of establishing semantic relations between terms or lexicalitems in the database. The classical relations of synonmy / antonymy, hyperonymy/ hyponymy, holonymy / meronymy, agent / instrument, agent / result,patient / instrument, cause / effect, and several others of the kind listed by Sager(1990:34–5) are already offered as choices, as is the possibility of establishing anew relationship, giving it a name, an acronym, a description, an example and theregistration of a reciprocal relationship, if appropriate. The objective here is to allowpeople to experiment with new semantic relations that may only be relevantto their own work.Experiments have been made with the organisation and visualisation of semanticrelations, as in Silva’s work (2003) which explores various semantic relationshipsof interest to the sub-domain of Mortality, developed within the frameworkof a much larger ontology for a dictionary and thesaurus for PopulationGeography, which started before the Corpógrafo was available and has not yetbeen formalised within it. One tool we should like to provide when possible is away of visualizing both more traditional, hierarchical, thesaurus-style ontologiesas well as the multi-dimensional concept systems summarised in Kageura (1997)and Bowker (1997).The lexical/phrasal databases offer the possibility of text and discourse analysisby classifying words and phrases according to the classification of Rhetorical StructureTheory 4 although users may create their own categories as well. This is clearlya somewhat experimental area, but we hope it will encourage further research.Despite the emphasis on semi-automatic selection of data from the corpora, itis possible to manually edit the information in the databases and include any termsor information acquired from non-corpora sources. The databases are designed tobe either monolingual or multilingual, and to include as much or as little informationas needed, and they can be partially or wholly exported to other formatsfor a variety of uses.3.
