XSemantic: An Extension of LCA Based XML Semantic Search
One of the most convenient ways to query XML data is a keyword search because it does not require any knowledge of XML structure or learning a new user interface. However, the keyword search is ambiguous. The users may use different terms to search for the same information. Furthermore, it is difficult for a system to decide which node is likely to be chosen as a return node and howmuch informa...
متن کاملFrom Revisiting the LCA-based Approach to a New Semantics-based Approach for XML Keyword Search
Most keyword search approaches for data-centric XML documents are based on the computation of Lowest Common Ancestors (LCA), such as SLCA and MLCA. In this paper, we show that the LCA is not always a correct search model for processing keyword queries over general XML data. In particular, when an XML database contains relationships among objects, which is quite common in practical data, LCA-bas...
متن کاملSemantic Based XML Context Driven Search And Retrieval System
we present in this paper, a context-driven search engine called XCD Search for answering XML Keyword-based queries as well as Loosely Structured queries, using a stack-based sort-merge algorithm. Most current research is focused on building relationships between data elements based solely on their labels and proximity to one another, while overlooking the contexts of the elements, which may lea...
متن کاملModeling Views for Semantic Web Using eXtensible Semantic (XSemantic) Nets
The emergence of Semantic Web (SW) and the related technologies promise to make the web a meaningful experience. Yet, high level modeling, design and querying techniques proves to be a challenging task for organizations that are hoping utilize the SW paradigm for their industrial applications, which are still using traditional database techniques. To address such an issue, in this paper, we pro...
متن کاملSemantic Search over XML Document Streams
A large number of web data sources, such as blogs, news sites and podcast hosts, are currently disseminating their content in the form of streaming XML documents. The variability and heterogeneity of those sources make the employment of traditional querying schemes, which are based on structured query languages, cumbersome for the end user (those languages require precise knowledge of the under...
