Atvasinājumu semantisko attieksmju modelis elektroniskajā vārdnīcā „Tēzaurs”
The model of semantic relations of derivatives in the electronic dictionary „Tēzaurs”

Summary/Abstract: This paper examines the introduction of a new resource of derivationally related lexemes into the electronic dictionary „Tēzaurs”; the resource consists of morphology links between dictionary entries (i.e., lexemes) and semantic links between individual senses of the base word and the derivative. Since polysemy of base words and derivatives is a subject that so far has not been studied in detail in Latvian linguistics, this aspect is examined in depth by focusing on semantic relations between the senses of base word and the derivative. The annotation of such relations is not possible without a detailed, corpus-based study of word semantics and reviewing of the dictionary entries, which is followed by selection and pairing of word groups for annotation, as well as the creation of a list of semantic roles characteristic for each word group. The article describes the process of developing the resource so far, the main challenges posed by it and the solutions for annotating derivationally related word senses of four main word groups: nouns, verbs, adjectives and adverbs. A separate chapter explores the various cases of asymmetric derivative relations between the base word and the derivative. It is projected that this resource will be useful for language learners and translators, as well as of special significance for linguists, who will have the opportunity to use the annotated material to study the various aspects of derivational semantics.
