We propose a three-step technique to achieve this purpose. First, we utilize a collection of XML namespaces organized into hierarchical structure as a medium for expressing data semantics. Second, we define the format of resource descriptor for the information source discovery scheme so that we can dynamically register and/or deregister the web data sources on the fly. Third, we employ an inverted-index mechanism to identify the subset of information sources that are relevant to a particular user query. We describe the design, architecture, and implementation of our approach—IWDS, and illustrate its use through case examples.

There are a lot of valuable data on the web that users may need to improve their decision making process. The answer of user query often exists in multiple web data sources. The extraction and combination of answers of user queries from different web data sources often fails because of syntax and semantic heterogeneity between user queries and web data sources. The retrieval and extraction of these answers from the different web data sources impose a need for queries to be syntactically and semantically mapped to web sources query languages. In this paper, we focus on semantic heterogeneity among user query terms and web data sources terms. We propose an approach for the semantic mapping of user query terms to web data sources terms.

There are hundreds or thousands of web data sources providing data of relevance to a particular domain on the web, so how to find a suitable set of sources quickly to integrate from a number of sources is becoming more and more important. Traditional data sources selection methods that are based on data quality do not consider quality characteristics of data sources under the different domains, but select the same quality dimensions for quality evaluation models. As a result, accuracies of a traditional method under different domains are quite different. In light of this, we propose a web multimedia source selection method based on user feedback. We gain accurate core quality dimensions of data sources under the multimedia domain based on user feedback, and then achieve a quality estimation model of the multimedia data sources. The experiments on hundreds of real-world multimedia data sources have proved that our approach is efficient and accurate. © 2011 IEEE.
