章節(jié)摘錄

　　Libraries were among the first institutions to adopt IR systems for retrieving information. Usually, library systems were initially developed by academic institutions and later by commercial vendors. In the first generation, such systems consisted of anautomation of existing processes such as card catalogs searching, restricted to authornames and titles. In the second generation, increased search functionality was added to include subject headings, keywords, and query operators. In the third generation,which is currently being deployed, the focus has been on improved graphical in terfaces,electronic f　　rms, hypertext features, and open system architectures.　　Traditional library management system vendors include Endeavor InformationSystems Inc., Innovative Interfaces Inc., and EOS International. Among systems developed with a research focus, we distinguish MELVYL developed by the California Digital Library at University of California, and the Cheshire system developed originally at UC Berkeley and lately in cooperation with the University of Liverpool.Further details on these library systems can be found in Chapter 16.1.1.3 IR at the Center of the Stage Despite its maturity, until recently, IR was seen as a narrow area of interest restrictedmainly to librarians and infrmation experts. Such a tendentious vision prevailed for many years, despite the rapid dissemination, among users of modern personalcomputers, of IR tools for multimedia and hypertext applications. In the beginning of the 1990s, a single fact changed once and for all these perceptions the in troductionof the World Wide Web.　　The Web, invented in 1989 by Tim Berners-Lee, has become a universal repository of human knowedge and culture. Its success is based on the conception of a standarduser interface which is always the same, no matter the computational environmentused to run the interface, and which allows any user to create their own documents.As a result, millions of users have created billions of documents that compose the largest human repository of knowledge in history. An immediate consequence is that finding useful information on the Web is not always a simple task and usually requiresposing a query to a search engine, i.e., running a search. And search is all aboutIR and its technologies. Thus, a hnost overnight, IR has gained a place with other technologies at the center of the stage.　　……
