Valency lexicon of Czech verbs has been intensively worked on for more than a year, and now we have at our disposal a detailed description of valency frames of several hundreds verbs. Presently, the challenge naturally arises, to use the existing lexicon for capturing valency of other word classes. In this paper, we focus on valency of nouns derived from verbs. We propose an algorithm for autom...

In this paper, we deal with changes in valency structure of Czech verbs from a lexicographic point of view. We focus only on syntactic constructions that are related in principle to the same (generalized) situation. Changes in valency structure are understood as different mappings between individual participants of a generalized situation and valency slots, including their morphemic realization...

The paper analyzes the differences in verbal valency frames between two related Slavic languages, Czech and Russian, with regard to their role in a machine translation system. The valency differences are a frequent source of translation errors. The results presented in the paper show that the number of substantially different valency frames is relatively low and that a bilingual valency diction...

Valency lexicons are valuable resources for natural language processing. The need for new resources for languages encourages researchers to collect new datasets. One of the most important datasets is valency lexicons. In valency lexicons, information about obligatory and optional complements of words is annotated at the syntactic and semantic levels. In this paper, we report the development of ...

1. Under comparable conditions, valency effect may be demonstrated with a suspension of red blood cells and the cations and anions of salts. 2. The valency of the cation determines the degree of the effect on negatively charged cells, the valency of the anion, the effect on positively charged cells. 3. Anomalies in valency effects with different salts and red cell suspensions are in part due to...

A development of a verb valency lexicon for Latvian has been recently started. The chosen approach combines and supplements the experience of similar lexical resources developed for other languages. The paper describes our approach to the verb valency annotation—the valency layers (syntactic and semantic valency, selectional restrictions) and the set of the semantic roles. The annotation proces...

Corpus-based Valency Lexicon of Czech Nouns is a starting project picking up the threads of our previous work on nominal valency. It builds upon solid theoretical foundations of the theory of valency developed within the Functional Generative Description. In this paper, we describe the ways of treating valency of nouns in a modern corpus-based lexicon, available as machine readable data in a fo...

Valency is a property of language units reflecting their combinatorial potential in language utterances. The availability of the information about valency is supposed to be crucial in various Natural Language Processing tasks. In general, valency of language units cannot be automatically predicted, and therefore it has to be stored in a lexicon. The primary goal of the presented work is to crea...
