Semantic web search engines can take advantage of machineunderstandable data published on the Web to provide more precise search results and advanced query capabilities. Semantic data embedded in web documents (serialized as RDFa or microformats, for example) can be used in conjunction with a semantic web search engine to provide a better web navigation experience. We present Semantic Navigator...

The dramatic growth of the Internet and of the Web traffic calls for scalable solutions to accessing Web documents. To this purpose, various caching schemes have been proposed and caching has been widely deployed. Since most Web documents change very rarely, the issue of consistency, i.e. how to assure access to the most recent version of a Web document, has received not much attention. However...

The large amount and heterogeneity of XML documents on the Web require the development of clustering techniques to group together similar documents. Documents can be grouped together according to their content, their structure, and links inside and among documents. For instance, grouping together documents with similar structures has interesting applications in the context of information extrac...

The dynamic collection and voluminous growth of information on the web poses great challenges for retrieving relevant information. Though most of the researchers focused their research work in the areas of information retrieval and web mining, still their focus is only on retrieving similar patterns leaving dissimilar patterns which are likely to contain the outlying data. So this paper concent...

This paper describes our experiences our experience in building and using a Web-based video library designed for educational use. The CAETI Internet Multimedia Library’s initial audience is K-12 schools; most of the content of our library comes from news and politics-related historical footage. The video library is a good tool not just for content but also for acquiring visual literacy. Politic...

More and more documents on theWorld WideWeb are based on templates. On a technical level this causes those documents to have a quite similar source code and DOM tree structure. Grouping together documents which are based on the same template is an important task for applications that analyse the template structure and need clean training data. This paper develops and compares several distance m...

The paper argues for the use of general and intuitive knowledge representation languages (and simpler notational variants, e.g. subsets of natural languages) for indexing the content of Web documents and representing knowledge within them. We believe that these languages have advantages over metadata languages based on the Extensible Mark-up Language (XML). Indeed, the retrieval of precise info...

This paper presents and compares two methods for evaluating the syntactic similarity between documents. The first method uses the Patricia tree, constructed from the original document, and the similarity is computed searching the text of each candidate document in the tree. The second method uses shingles concept to obtain the similarity measure for every document pairs, and each shingle from t...

Documents summarization techniques automatically extract information from different sources . The main propose of this paper is summarizing documents that retrieve from internet. The propose to capture the document from internet , that document store in database ,extract that documents, use the natural language, in order to retrieve similar information. An overview of the system and some prelim...
