Lemma Selection and Microstructure

We design a bilingual electronic dictionary for the mathematical domain of graph theory. The target group of the dictionary are students in the field, and the dictionary should support them in both cognitive and communicative situations. Therefore, it will not only provide equivalents but also an ontology of the terminology. The dictionary is based on a corpus and the lemmas are selected by combining results of automatic extraction tools with the work of expert raters. For the microstructure, a domain-specific scheme is developed and presented. The lemmas are divided into nine categories (one for adjectives, one for verbs and seven for nouns). In addition, we introduce thirteen semantic relations for which information can be given in the microstructure, depending on the category of the lemma. The microstructure items for each semantic relation are introduced by means of a specific indicator phrase, as the target group might not be acquainted with the linguistic terminology.
