Paradigmatic Morphology and Subjectivity Mark-Up in the RoWordNet Lexical Ontology

Lexical ontologies are fundamental resources for any linguistic application with wide coverage. The reference lexical ontology is the ensemble made of Princeton WordNet, a huge semantic network, and SUMO&MILO ontology, the concepts of which are labelling each synonymic series of Princeton WordNet. This lexical ontology was developed for English language, but currently there are more than 50 similar projects for languages all over the world. RoWordNet is one of the largest lexical ontologies available today. It is sense-aligned to the Princeton WordNet 2.0 and the SUMO&MILO concept definitions have been translated into Romanian. The paper presents the current status of the RoWordNet and some recent enhancement of the knowledge encoded into it.
