To improve document clustering, a document similarity measure based on cosine vector and keywords frequency in documents is proposed, but also with an input ontology. The ontology is domain specific and includes a list of keywords organized by degree of importance to the categories of the ontology, and by means of semantic knowledge, the ontology can improve the effects of document similarity measure and feedback of information retrieval systems. Two approaches to evaluating the performance of this similarity measure and the comparison with standard cosine vector similarity measure are also described.展开更多

In order to better understand the issue, the same pair of opposites is discussed at length on the basis of Narayana＇s earlier Malayalam poems--devotional hymns （Siva Satakarn--＂One Hundred Verses on Siva＂, Kah Natakam--＂Dance of Kali＂, and Janani Nava Ratna Manjari--＂Nine Gemmed Bouquet to Mother＂） as well as later Sanskrit philosophical work [Darsuna Mala--＂Garland of Visions＂）. The comparative analysis of these texts demonstrates that--whereas Darsana Mala reflects more or less accurately Vedantic concepts, Atrnopadesa Satakam presents deeply syncretic formation, influenced to a large extent by philosophical systems related to bhakti （devotion）, like Sata or Saiva Siddhanta. The reason for such a state of affairs could be the purpose of Malayalam work destined to become vehicle for instructions given to lower caste people in Kerala. The paper offers an analysis of the relevant passages of the texts accompanied with explanatory notes extracted from the commentarial literature.展开更多
