Topic Segmentation and Evaluation Measures for E-learning based on Domain and Pedagogical Ontology

This paper discusses the UNL Enconversion of Tamil sentences. The rich morphology of Tamil enables the Enconversion process to be based on morpho-semantic features of the words and their preceding and succeeding context. The use of case relation indicating morphological suffixes, POS tag and word level semantics allows the rule based Enconversion to be independent of the syntactic structure of the sentence. These UNL graphs are used to build a conceptual level index.
