There are some situations these days in which it is important to have an efficient and reliable classification of a web-page from the information contained in the Uniform Resource Locator (URL) only, without the need to visit the page itself. For example, a social media website may need to quickly identify status updates linking to malicious websites to block them. The URL is very concise, and ...
The paper presents a generalization of Iterative Cross-Training algorithm (ICT) which was previously applied to Thai Web pages identification [1]. The main concept of ICT is to iteratively train two sub-classifiers by using unlabeled examples in crossing manner. In this paper, we extend the algorithm in order to classify Web pages into course or non-course ones, which is a more challenging prob...
With the emergence of the World Wide Web, analyzing and improving Web communication has become essential to adapt the Web content to the visitors’ expectations. Web communication analysis is traditionally performed by Web analytics software, which produce long lists of page-based audience metrics. These results suffer from page synonymy, page polysemy, page temporality, and page volatility. In ...
Dimensionality refers to number of terms in a web page. While classifying web pages high dimensionality of web pages causes problem. The main objective of reducing dimensionality of web pages is improving the performance of classifier. Processing time and accuracy are two parameters which influence the performance of a classifier. To reduce the processing time, less informative and redundant te...
Automatic categorization is the only viable method to deal with the scaling problem of the World Wide Web (WWW). In this paper, we propose a news web page classification method (WPCM). The WPCM uses a neural network with inputs obtained by both the principal components and class profile-based features. Each news web page is represented by the term-weighting scheme. As the number of unique words...
Content-related metadata plays an important role in the effort of developing intelligent web applications. One of the most established form of providing contentrelated metadata is the assignment of web-pages to content categories. We describe the Spectacle system for classifying individual web pages on the basis of their syntactic structure. This classification requires the specification of cla...
The research reported in this paper is part of a larger project on the automatic classification of web pages by their genres. The long term goal is the incorporation of web page genre into the search process to improve the quality of the search results. In this phase, a neural net classifier was trained to distinguish home pages from non-home pages and to classify those home pages as personal h...
Clustering is the unsupervised classification of patterns (data items, observations or feature vectors) into groups (clusters). Clustering problem has been addressed by the researchers of many disciplines in different contexts. Due to the escalating amount of data available online, the World Wide Web has become one of the most precious resource for information retrievals and knowledge discoveri...
