The heterogeneous data on the web related to the geographic information of a country is an increasingly important field of data sharing and integrating with diverse sources for retrieving suitable information using search engines. These heterogeneous geographic data is mostly available in unstructured or semi-structured format. Converting and integrating these data into a machine understandable representation...
Social bookmarking tools are rapidly emerging on the Web as it can be witnessed by the overwhelming number of participants. In such spaces, users annotate resources by means of any keyword or tag that they find relevant, giving raise to lightweight conceptual structures aka folksonomies.

To improve the retrieval performance, shallow parsing technique for text was introduced for Chinese Web information retrieval. Firstly, predicate, prepositive nominal component and succedent nominal component close to the predicate were extracted from Chinese sentence. Then, semantic vector of Chinese text was acquired based on converting predicate and nominal component to conception. An algorithm...
Ontology engineering is the task of creating and refining a knowledge model for one or multiple domains. This process is difficult and a great deal of time is required to refine the ontology. In this paper, we present a system that semi-automatically aids the user in creating an ontology using a standard web browser. Our system helps to create ontologies whose target domain can be found on the web...
