Semantic Mappings in Description Logics for Spatio-temporal Database Schema Integration

2005

International audience; The interoperability problem arises in heterogeneous systems where different data sources coexist and there is a need for meaningful information sharing. One of the most representive realms of diversity of data representation is the spatio-temporal domain. Spatio-temporal data are most often described according to multiple and greatly diverse perceptions or viewpoints, using different terms and with heterogeneous levels of detail. Reconciling this heterogeneity to build a fully integrated database is known to be a complex and currently unresolved problem, and few formal approaches exist for the integration of spatio-temporal databases. The paper discusses the interope…

Modal verbs, future and grammaticalization in Old Catalan : a cognitive approach

2015

The process of grammaticalization of Catalan modal verbs deure, haver and tenir involves a semantic change, a rise of new meanings and an increase in their semantic network. On the one hand, deontic modal verbs develop inferential evidential meanings, and, on the other, future meanings (posteriority).This corpus-based study focuses on the rise of future meanings of modal verb deure ('must') (between the 12th and the 16th centuries). We have been able to analyse the process of grammaticalization with absolute reliability thanks to the applied technology of the Corpus of Old Catalan (CICA and CIGCA), in which linguistic variation is quite representative. This study takes a cognitive perspecti…
