Due to the popularity of online auction markets, auction fraud has become common. Typically, fraudsters will create many accounts and then transact among these accounts to get a higher rating score. This is easy to do because of the anonymity and low fees of the online auction platform. A literature review revealed that previous studies focused on detection of abnormal rating behaviors but did ...

Now-a-days the web based information is increasing day-by-day. As the number of internet users and the number of web document grows, it is difficult for users to find the documents that are relevant to their particular needs.In Recent years semantic web search is not considering semantic relations between words in traditional Machine Learning algorithms. Previous works on ontology-based semanti...

We introduce several new versions of PageRank (the link based Web page ranking algorithm), based upon an information science perspective on the concept of the Web document. Although the Web page is the typical indivisible unit of information in search engine results and most Web information retrieval algorithms, other research has suggested that aggregating pages based upon directories and doma...

Search spam is an attack on search engines’ ranking algorithms to promote spam links into top search ranking that they do not deserve. Cloaking is a wellknown search spam technique in which spammers serve one page to search-engine crawlers to optimize ranking, but serve a different page to browser users to maximize potential profit. In this experience report, we investigate a different and rela...

Web is the boundless source of information and no one is able to process the vast amount of new documents published on the web every day, even with filtering out the documents the user is not interested in. However, most of the recent web documents are blog posts, news and other documents with the author information established. Each author who is also the receiver of web documents possesses th...

Paper repository at higher education is a collection of scientific articles created by the academic society. This study took as many as 80 universities in the Webometrics ranking of repositories in the Southeast Asia region. The tools used in this research is Google for number of web page and Google Scholar for number of document paper repository and Ahrefs for referring page, backlink and reff...

Search engines are used to catalog and organize the vast amount of information available on the internet. Engines use linear algebra to match a user query to words within a document, and also use a matrix model of the hyperlink structure of the internet to determine the inherent worth of each page. This ranking is used to organize results when returned to the user.

This paper introduces a family of link-based ranking algorithms that propagate page importance through links. The algorithms include a damping function which decreases with distance, thus a direct link implies greater endorsement that a link via a longer path. PageRank is the most widely known ranking function of this family. The main objective of this paper is to determine whether this family ...

This paper combines cryptographic voting and web page ranking and proves that it is possible to hold elections so as not to limit a voter by a list of candidates, to benefit from voter’s personal experience in dealing with people, to make wide and proportional representation, and to achieve secrecy, including incoercibility, and verifiability of cryptographic voting systems.

Question answering has been a focus of much attention from academia and industry. Search engines have already tried to provide direct answers for question-like queries. Among these queries, “What” is one of the biggest segments. Since results excerpted fromWikipedia often have a coverage problem, some models begin to rank definitions that are extracted from web documents, including Ranking SVM ...
