This paper studies the problem of building Web page classifiers using positive and unlabeled examples, and proposes a more principled technique to solving the problem based on tolerance rough set and Support Vector Machine (SVM). It uses tolerance classes to approximate concepts existed in Web pages and enrich the representation of Web pages, draws an initial approximation of negative example. ...

A vast body of digital content lies in the World Wide Web, to which people can access via web browsers. Automatic speech recognition as well as Text-toSpeech (TTS) components have been incorporated into some web browsers aiming to assist the visually impaired access web content. Various webpagereader programs usually read out textual content sequentially as appeared on the webpages. Many times,...

Automated Genre Identification (AGI) of web pages is a problem of increasing importance since web genre (e.g. blog, news, eshops, etc.) information can enhance modern Information Retrieval (IR) systems. The state-of-the-art in this field considers AGI as a closed-set classification problem where a variety of web page representation and machine learning models have intensively studied. In this p...

One of the characteristic features of the World Wide Web is that it allows anyone to publish web pages, and to link their pages to any other web pages. The emergent result of this process is that communities arise that are focused around subjects of common interest. Identifying these communities can be challenging, due to the large size of the web graph and the unstructured nature of publishing...

Nowadays, the Web is an important source of information retrieval, and the users accessing the Web are from different backgrounds. The usage information about users are recorded in web logs. Analyzing web log files to extract useful patterns is called Web Usage Mining. Web usage mining approaches include clustering, association rule mining, sequential pattern mining etc. The web usage mining ap...

A Composite Memento is an archived representation of a web page with all the page requisites such as images and stylesheets. All embedded resources have their own URIs, hence, they are archived independently. For a meaningful archival replay, it is important to load all the page requisites from the archive within the temporal neighborhood of the base HTML page. To achieve this goal, archival re...

Current practice of Web site development does not address explicitly the problems related to multilingual sites. The same information, as well as the same navigation paths, page formatting and organization, are expected to be provided by the site independently from the chosen language. This is typically ensured by adopting personal conventions on the way pages are named and on their location in...

Web pages with complex layout do not display well on small screens, and require extensive amounts of scrolling, both horizontally and vertically. This quickly leads to disorientation within the page. In order to make optimum use of the small displays on mobile devices for Web browsing and searching, it is necessary to enforce both overview and detail concerns of page viewing. However, this typi...

Web page recommendation is a process to recommend appropriate web pages to the user according to the user interest.When user is on a webpage they should get a proper recommendation so that they gain relevant results. Appropriate knowledge discovery from Web usage data and correct representation of that knowledge for successful Web -page recommendation is important. The paper presents a techniqu...
