2Zamir, O. ; Etzioni, O.: Grouper : a dynamic clustering interface to Web search results.
In: Computer networks. 31(1999) no.11-16, S.1361-1374.
Abstract: Clustering is an effective way of organizing documents into collections for ease of browsing. Recently with the growth of WWW, clustering has become a paradigm for organizing search results. Online systems face many new challenges, including the need for fast response time, generating high quality clusters with simple descriptions for novice users, and working with document distributions that violates many traditional assumptions. How do different clustering algorithms trade off quality of clusters and speed? What modifications are necessary to adapt traditional clustering algorithm to the WWW? How do these system scale to larger document collection? How do these systems evaluate the quality of the cluster they generate? How are the clusters generated in each case, and are there any processing after cluster generation to improve on the cluster quality?

3Selberg, E. ; Etzioni, O.: ¬The MetaCrawler architecture for resource aggregation on the Web.
In: IEEE expert. 12(1997) no.1, S.11-14.
Abstract: 2nd part of a 2 part section on search engines for the WWW. The MetaCrawler Softbot ia a parallel WWW search service which has been available since 1994. It provides a single interface search service. Describes the advantages of this type of system, how it operates, its architectural design and future development plans
4Shakes, J. ; Langheinrich, M. ; Etzioni, O.: Dynamic Reference Sifting : a case study in the homepage domain.
In: Computer networks and ISDN systems. 29(1997) no.8, S.1193-1204.
Abstract: Presents Dynamic Reference Sifting - a novel architecture that attempts to provide both maximally comprehensive coverage and highly precise responses in real time, for specific home page categories. Describes Ahoy! The Homepage Finder (http://www.cs.washington.edu/research/ahoy), a fielded Web service that embodies Dynamic Reference Sifting for the domain of personal homepages. Ahoy! filters the output of mulptile Web indices to extract 1 or 2 references that are most likely to point to the person's homepage. If it finds no likely candidates, Ahoy! uses knowledge of homepage placement conventions, which it has accumulated from previous experience, to guess the URL for the desired homepage. Ahoy! finds the target homepage and ranks it as the top reference. 9% of the targets are found by guessing the URL. altaVista can find 58% of the targets and ranks only 23% of these as the top reference

5Etzioni, O. ; Weld, D.S.: Intelligent agents on the Internet : fact, fiction, and forecast.
In: IEEE expert. 10(1995) no.4, S.44-49.
Abstract: Descusses intelligent information agents that are currently in use on the Internet. Describes the architecture and development approach used to provide scalable services to a wider range of users. Feedback from users is being used to refine and improve the intelligent agent service
