Resumen de Planning a Domain-specific Electronic Dictionary for the Mathematical Field of Graph Theory: Definitional Patterns and Term Variation

Theresa Kruse, Laura Giacomini

• We plan to create an electronic dictionary for the mathematical field of graph theory. The dictionary should help students to improve their usage of the mathematical terminology. Besides the alphabetical access, the dictionary will also provide thematic, onomasiological access; it will contain lemmas in German and English, related terms and equivalence statements. Presently, such a dictionary does not exist. The dictionary basis is formed by two corpora composed of textbooks, scientific papers and lecture notes, containing all the texts the students use in their graph theory course in German and English. In the current pre- lexicographic stage, our focus is on relations between terms and on patterns used in the corpus to express them. We collect the definition patterns in the corpus and plan to use them for term extraction. Thereby, we can extract the semantic relations at the same time. In this paper we explore in particular the synonymy relations from an orthographical, morphological and syntactic perspective and draw conclusions for data acquisition. It might be possible to apply our extraction methods later for creating dictionaries in other mathematical domains.
