The World Wide Web has a massive number of Web pages, making it difficult for users to find useful information accurately. Most Web search engines have been constructed by considering Web page content and link structure. Recently, the probabilistic language model has been developed to improve retrieval accuracy of Web searches. The probabilistic language model calculates probabilities of query terms...
Nowadays, using web and Internet as a world wide information system faces us with so many data. In this direction, the necessity of accessing some tools for data processing in web level which helps the man intelligently to transform these data into useful knowledge seems so important. Clustering the web pages is one of these techniques. In this paper, a new algorithm has been represented to cluster...
Improving the relevancy of Web search results has been of increasing interest in recent years. The nature of the Web implies heterogeneity, large volumes, and varied structures. Hence, finding results that best suit the needs of every individual is a very challenging problem. Accordingly, interactive graphical and visualization techniques are suggested to increase the ability of the display to handle...
This paper offers a fresh perspective on the aspect of application security, highlighting a sample attack that is not currently being protected against. Here is a case study which discussed identifying poor coding practices that render Web applications vulnerable to attacks such as remote command execution. Given the increased focus on the need for application security, it is now to be hoped that...
An e-Government portal is responsible to provide news, information and services to citizens, merchants and tourists in a reliable way. Previously, we proposed a Web Monitoring System (WMS) that monitors the performance of a web portal in realtime. Web portal structure is complex to analyze though it is important to discover useful patterns, evaluate performance, locate anomalies and identify problems...
In recent years, the free online encyclopaedia Wikipedia has become a standard resource to exploit to build knowledge base for various Natural Language Processing applications. In this paper, we exploit that resource to design a new query classification system. We explain and justify the steps we take to extract information from Wikipedia into a structured database, in order to demonstrate the validity...
In this paper, we attempt to get better insight on how Internet usage behaviors of female students in university can affect on their different academic activities also compare usage patterns of different departments' students with their teachers' patterns. In addition, we attempt to find similarities and dissimilarities of usage patterns of students on various branches and finding relationships between...
e-commerce can be seen from different points of view. Its fields are always facing new challenges, variable conditions, evolving requirements, and thus new improvements are constantly demanded. Therefore, the importance for a usable and secure e-commerce website structure is more than necessary nowadays. In this paper we propose a requirements taxonomy consisting of the factors of security, usability,...
Accelerated growth of the Internet has enabled users worldwide to share their feelings and experiences. User-generated content (UGC) websites are the most abundant sources of user reviews. Accurately identifying sentiment phrases is essential to understand the expressed opinions in user reviews. To achieve this, part-of-speech (POS) patterns of phrases are useful. However, previous studies for Chinese...
Automatic topic detection becomes more important due to the increase of information electronically available and the necessity to process and filter it. In particular, when language is noisy like in weblog postings, it is challenging to determine topics correctly. Nevertheless, it is still unclear, to what extent existing topic detection algorithms are able to deal with this noisy material. In this...
