In this respect, there are aspects that are still partially known. In particular, we apply the OVL to two lexical resources for Latin, namely the valency lexicon Latin Vallex and the Latin WordNet. In this paper, we present a method for measuring the degree of similarity between such resources by proposing a normalized coefficient of overlapping (OVL). Words are included into synsets, which are sets of words “that are interchangeable in some context without changing the truth value of the proposition in which they are embedded” 1.ĤDespite their differences, the views on lexical meaning pursued by valency-based lexical resources and WordNet are not incompatible. ģInstead, both syntactic subcategorization and semantic roles do not play any role in WordNet (Miller 1995), which pursues a different view on lexical meaning based on the idea of synonymy in the broad sense. In this respect, PropBank is semantically more coarse-grained than both VerbNet and FrameNet, as it labels arguments according to syntactic subcategorization instead of assigning them semantic roles. The degree of semantic granularity of the set of semantic roles assigned to arguments is one of the aspects that mostly distinguishes valency-based lexical resources like PropBank (Palmer, Gildea, and Kingsbury 2009), VerbNet (Kipper 2005) and FrameNet (Baker, Fillmore, and Lowe 1998) one from the other. Although different parts of speech (PoS) can be valency-capable, scholars have mainly focused on verbs, so that the notion of valency tends to coincide with that of verbal valency.ĢThere is large use of the notion of valency in lexical resources. ![]() These obligatory complements are usually named arguments, while the non-obligatory ones are referred to as adjuncts. The notion of semantic frame subsumes that of valency ((Ágel and Fischer 2010) (Tesnière 1959)), which is defined as the number of obligatory complements required by a word. ![]() IntroductionġViewing lexical semantics through predicate-argument structure strictly relates with the basic assumption of Frame Semantics (Fillmore 1982), according to which the meaning of some words can be fully understood only by knowing the frame elements that are evoked by those words. Special thanks should be given to Berta González Saavedra for building Latin Vallex and to Christophe Onambele for both providing helpful remarks and computing the results shown in Table 2. In particular, in the context of the exploitation of the linguistic resources for ancient languages built over the last decade, we compute and evaluate the overlapping between a selection of homogeneous lexical subsets extracted from two lexical resources for Latin. In order to apply and evaluate our method, we propose a normalized coefficient of overlapping that measures the overlapping rate between a valency lexicon and a WordNet. As for the latter, our work wants to contribute to the research task dealing with merging lexical resources. As for the former, we wonder if there are lexical classes that "impose" themselves regardless of the fact that they are explicitly recorded as such in source lexical resources. This is motivated by both theoretical and practical reasons. ![]() ![]() In this paper, we present a method for measuring the degree of similarity between a valency-based lexical resource and a WordNet. However, all of them deal with lexical items as common basic components, which are described according to criteria that may vary from one resource to another. Different lexical resources may pursue different views on lexical meaning.
