Using Coherent Semantic Subpaths to Derive Emergent Semantics
نویسندگان
چکیده
We contend that the author of a Web page cannot completely define that document’s semantics and that semantics emerge through use. Semantics is context-sensitive. User browsing paths over a multimedia collection provide, we believe, the necessary context to derive semantics. We attempt to use information from several modalities to improve retrieval using a single modality. We have developed and tested several algorithms to detect breakpoints and cluster Web pages into groups that exhibit uniform semantics. We have also used visual-keywords to improve textual-keyword based searches.

Dynamic Categorization of Semantics of Fashion Language: A Memetic Approach
Categories are not invariant. This paper attempts to explore the dynamic nature of semantic category, in particular, that of fashion language, based on the cognitive theory of Dawkins’ memetics, a new theory of cultural evolution. Semantic attributes of linguistic memes decrease or proliferate in replication and spreading, which involves a dynamic development of semantic category. More specific...
متن کاملLexical Semantics and Selection of TAM in Bantu Languages: A Case of Semantic Classification of Kiswahili Verbs
The existing literature on Bantu verbal semantics demonstrated that inherent semantic content of verbs pairs directly with the selection of tense, aspect and modality formatives in Bantu languages like Chasu, Lucazi, Lusamia, and Shiyeyi. Thus, the gist of this paper is the articulation of semantic classification of verbs in Kiswahili based on the selection of TAM types. This is because the sem...

The word istikbar (arrogance) is one of the key words in the monotheistic system of the Quran, which has found a special status as a special feature of the opponents and adversaries of the call to the truth. Given the prominent role of this issue in the human life system and its provision of corruption and moral deviations, it is necessary to represent the nature of the elements that make up th...

To survive in the twenty-first century, enterprises need to collaborate. Collaboration at the enterprise-level presupposes the interoperability of the underlying information systems. Access to heterogeneous information sources must be provided transparently while maintaining their autonomy. Further, the availability of nearly unlimited information calls for efficient and precise information ret...
