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.
This paper deals with semi-automatic extension of CroDeriV with verb valency frames. CroDeriV is a morphological database of Croatian verbs. In its present shape the database comprises 14 500 verbs in infinitive forms. Each verb in CroDeriV is segmented into lexical and derivational morphemes and verbs of the same root are mutually linked. In order to further enrich the CroDeriV with semantic and syntactic information, we have used the NooJ platform to recognize derivationally related verbs, find the verb frames and to speed up the sentence processing.
This paper demonstrates how to generate natural language sentences from the pieces of data found in databases in the domain of flight tickets. By using NooJ to add context to specific customer data found in customer data sets, we are able to produce sentences that give a short textual summary of each customer, providing a list of possible suggestions how to proceed. In addition, due to the rich morphology of Croatian, we are giving special attention to matching gender, number and case information where appropriate. Thus, we are able to provide individualized and grammatically correct text in spite of the customer gender or the number of tickets bought and inquiries made. We believe that such short NL overviews can help ticket sellers get a quicker assessment of the type of a customer and allow for the exchange of information with more confidence and greater speed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
