“…Thus, the analysis, especially the relation co-occurrence patterns cannot be directly mapped to the other wordnets for other languages. However, all Slavic languages have derivational systems of similar character (Šojat & Srebačić, 2014), BulNet (Koeva, 2008) or CzechWordnet (Pala & Hlaváčková, 2007). Their wordnet models show many differences in comparison to the plWordNet's one, but such differences are not very significant, e.g.…”

The paper presents patterns of co-occurrences of wordnet relations involving verb lexical units in plWordNet a large wordnet of Polish. The discovered patterns reveal tendencies of selected synset and lexical relations to form regular circular structures of clear semantic meanings. They involve several types of relations, e.g., presupposition, cause, processuality and antonymy, do not have a necessary character (there are exceptions), but can be used in wordnet diagnostics and guidelines for wordnet editors. The analysis is illustrated with numerous positive and negative examples, as well as statistics for verb relations in plWordNet 4.0 emo. Some attempts to a more general, linguistic explanation of the observed phenomena are also made. As a background, pl-WordNet model of linguistic character is briefly recollected. A special attention is given to the verb part. In addition the description of dynamic verbs by relations and features is discussed in details including relation definitions and substitution tests.

“…7 Derivational relations are included in other language resources, too, though rather marginally. In Czech WordNet a set of 14 relations was implemented (Pala and Smrž, 2004;Pala and Hlaváčková, 2007). In the Prague Dependency Treebank (Hajič et al, 2006), selected types of derivatives were represented by the lemma of their base word within the deep-syntactic annotation (Razímová and Žabokrtský, 2006).…”

The present paper deals with morphographemic alternations in Czech derivation with regard to the build-up of a large-coverage lexical resource specialized in derivational morphology of contemporary Czech (DeriNet database). After a summary of available descriptions in the Czech linguistic literature and Natural Language Processing, an extensive list of alternations is provided in the first part of the paper with a focus on their manifestation in writing. Due to the significant frequency and limited predictability of alternations in Czech derivation, several bottom-up methods were used in order to adequately model the alternations in Der-iNet. Suffix-substitution rules proved to be efficient for alternations in the final position of the stem, whereas a specialized approach of extracting alternations from inflectional paradigms was used for modelling alternations within the roots. Alternations connected with derivation of verbs were handled as a separate task. DeriNet data are expected to be helpful in developing a tool for morphemic segmentation and, once the segmentation is available, to become a reliable resource for data-based description of word formation including alternations in Czech. 1 In the paper, the term "root" refers to a morpheme that cannot be further analysed while "stem" is used, less specifically, for the part of a word without inflectional affixes (Haspelmath and Sims, 2010; Aronoff, ). Roots and stems are not together referred to as "bases" (cf. Bauer, 1983, pp. 20f) since we reserve the term "base" for the opposition of a base word vs. a derived word (target word, or derivative). These pairs are referred to as "pairs of base-target words" or "base-target pairs", too. 2 In the examples, the base word is written first followed by the derivative, the derivational relation is represented by an arrow. The alternations that accompany the derivation are listed above the arrow. The grapheme in the base is written first followed by ">" and the corresponding grapheme in the derivative. Boundaries between morphemes are indicated with the hyphens (the morphemic structure is not marked in Sect. 4 since the data are not segmented in the DeriNet network). In examples on diminutive derivation, we use "dimin." (diminutive) and "double dimin." (double diminutive) instead of the full English translation (e.g. 'small hippo' and 'very small hippo', respectively). M. ŠevčíkováModelling Morphographemic Alternations in Czech

This paper deals with certain morphosemantic relations between Croatian verbs and discusses their inclusion in Croatian WordNet. The morphosemantic relations in question are the semantic relations between unprefixed infinitives and their prefixed derivatives. We introduce the criteria for the division of aspectual pairs and further discuss verb prefixation which results in combinations of prefixes and base forms that can vary in terms of meaning from compositional to completely idiosyncratic. The focus is on the regularities in semantic modifications of base forms modified by one prefix. The aim of this procedure is to establish a set of morphosemantic relations based on regular or reoccuring meaning alternations.
