	Web error classification and analysis for reliability improvement Ma L., Tian J. Journal of Systems and Software 80(6): 795-804, 2007. Type: Article A Web server log is an important source of information for Web site developers and administrators since it records the browsing behavior of a site’s visitors. Analyzing Web server logs is useful for identifying both Web users’...

	Graph theory: modeling, applications, and algorithms Agnarsson G., Greenlaw R., Prentice-Hall, Inc., Upper Saddle River, NJ, 2007. 464 pp. Type: Book Graph theory is the study of mathematical structures used to model pairwise relations between objects from a certain collection. It has a broad range of applications in computer science (CS) and information engineering (IE), engineering, social...

	Combinatorial methods with applications (Discrete Mathematics and its Applications) Gross J., Chapman&Hall/CRC, 2007. 664 pp. Type: Book Have you ever wondered why books on combinatorial methods attract more and more computer-science (CS) readers? The answer lies in the fact that these methods have been proved critical to the construction of fast algorithms. In particular,...

	Query enrichment for Web-query classification Shen D., Pan R., Sun J., Pan J., Wu K., Yin J., Yang Q. ACM Transactions on Information Systems 24(3): 320-352, 2006. Type: Article Web query classification is a rather interesting area of research, since Web users’ queries are typically short, noisy, and ambiguous. This paper presents a new approach to classifying Web search queries, made up of two phases. First, the...

	Exploring spatial datasets with histograms Sun C., Bandi N., Agrawal D., El Abbadi A. Distributed and Parallel Databases 20(1): 57-88, 2006. Type: Article Spatial database management systems (for example, geographical information systems) often suffer from high query processing costs. With the recent availability of massive amounts of online spatial data, there are strong demands for the...
