Authoritative Sources in a Hyperlinked Environment
- JOURNAL OF THE ACM
, 1999
"... The network structure of a hyperlinked environment can be a rich source of information about the content of the environment, provided we have effective means for understanding it. We develop a set of algorithmic tools for extracting information from the link structures of such environments, and repo ..."

, and report on experiments that demonstrate their effectiveness in a variety of contexts on the World Wide Web. The central issue we address within our framework is the distillation of broad search topics, through the discovery of “authoritative ” information sources on such topics. We propose and test
Data Mining: Concepts and Techniques
, 2000
"... Our capabilities of both generating and collecting data have been increasing rapidly in the last several decades. Contributing factors include the widespread use of bar codes for most commercial products, the computerization of many business, scientific and government transactions and managements, a ..."

In addition, popular use of the World Wide Web as a global information system has flooded us with a tremendous amount
Combating web spam with trustrank
- In VLDB
, 2004
"... Web spam pages use various techniques to achieve higher-than-deserved rankings in a search engine’s results. While human experts can identify spam, it is too expensive to manually evaluate a large number of pages. Instead, we propose techniques to semi-automatically separate reputable, good pages fr ..."

and the discovery of good pages. We present results of experiments run on the World Wide Web indexed by AltaVista and evaluate the performance of our techniques. Our results show that we can effectively filter out spam from a significant fraction of the web, based on a good seed set of less than 200 sites. 1
A software framework for matchmaking based on semantic web technology
, 2003
"... An important objective of the Semantic Web is to make Electronic Commerce interactions more flexible and automated. To achieve this, standardisation of ontologies, message content and message protocols will be necessary. In this paper we investigate how Semantic and Web Services technologies can be ..."

be used to support service advertisement and discovery in ecommerce. In particular, we describe the design and implementation of a service matchmaking prototype which uses a DAML-S based ontology and a Description Logic reasoner to compare ontology based service descriptions. By representing the semantics
Negative Electronic Word-of-Mouth Online Consumer Reviews: Does Negative Electronic Word-of-Mouth Hurt More?
"... Web-based technologies have created numerous opportunities for electronic word-of-mouth (eWOM) communication. This phenomenon impacts retailers as this easily accessible information could greatly affect consumer purchasing decision. The connectivity of the Web allows one-to-many and many-to-many com ..."

Computing Word-of-Mouth Trust Relationships in Social Networks from Semantic Web and Web2.0 Data Sources
"... Abstract. Social networks can serve as both a rich source of new information and as a filter to identify the information most relevant to our specific needs. In this paper we present a methodology and algorithms that, by exploiting existing Semantic Web and Web2.0 data sources, help individuals iden ..."

SPAND: Shared Passive Network Performance Discovery
- IN USENIX SYMPOSIUM ON INTERNET TECHNOLOGIES AND SYSTEMS
, 1997
"... In the Internet today, users and applications must often make decisions based on the performance they expect to receive from other Internet hosts. For example, users can often view many Web pages in low-bandwidth or high-bandwidth versions, while other pages present users with long lists of mirror s ..."

Knowledge Discovery from Users Web-Page Navigation
- in Proceedings of workshop on research issues in Data engineering
, 1997
"... We propose to detect users navigationpaths to the advantage of web-site owners. First, we explain the design and implementationof a profiler which captures client’s selected links and pages order, accurate page viewing time and cache references, using a Java based remote agent. The information captu ..."
