One of the key requirements of portals is easy access to information, or findability according to Morville’s definition (Morville, 2002). After a decade of using traditional access paradigms, such as queries on structured database systems and information retrieval or search engines, the feeling that “search does not work” and “information is too hard to find is now reaching a consensus level. The problem is that traditional access paradigms are not suited to most search tasks, that are exploratory and imprecise in essence: the user needs to explore the information base, find relationships among concepts and think alternatives out in a guided way. New access paradigms supporting exploration are needed. Since the goal is end-user interactive access, a holistic approach in which modeling, interface and interaction issues are considered together, must be used and will be discussed in the following.

End-user interactive access to complex information is one of the key functionalities of knowledge management systems. Traditionally, access paradigms have focused on retrieval of data on the basis of precise specifications: examples of this approach include queries on structured database systems, and information retrieval. However, most search tasks, and notably those typical of a knowledge worker, are exploratory and imprecise in essence: the user needs to explore the information base, find relationships among concepts, and thin alternatives out in a guided way.

Intelligent Information

End-user interactive access to complex information is a key requirement in most applications, from knowledge management, to e-commerce, to portals. Traditionally, only access paradigms based on the retrieval of data on the basis of precise specifications have been supported. Examples include queries on structured databases and information retrieval. There is now a growing perception that this type of paradigm does not model a large number of search tasks, such as product selection in e-commerce sites among many others, that are imprecise and require exploration, weighting of alternatives and information thinning. The recent debate on findability (Morville, 2002) and the widespread feeling that “search does not work” and “information is too hard to find” shows evidence of the crisis of traditional access paradigms. New access paradigms supporting exploration are needed. Because the goal is end-user interactive access, a holistic approach in which modeling, interface and interaction issues are considered together, must be used and will be discussed in the following.

A Library is an institution in the field of information provider services oriented to the needs of users. Five library laws put forward by S.R. Ranganathan (books are for use, every reader his book, every book its reader, save the time of the reader and the staff, library is a growing organism) has become one of the references in library collections development that are oriented to user needs. Implementation of five library laws according to Ranganathan are (1) Library collections must be regularly evaluated. The results of this evaluation can then be used as a reference in weeding activities. It is intended that each book can be used optimally. (2) A series of procurement procurement proseas that include user analysis, selection, selection, and procurement policies must be oriented to user needs. It aims to make every information that users need available in the library. (3) Accuracy in the processing and display management becomes important in information retrieval. It is intended that every book in the library can be accessed. (4) Libraries must provide easy access to users to get information as effectively and efficiently as possible. This is so that users do not waste time looking for collections in the library. (5) Libraries must adapt to the changing environment that is always developing. The development and fulfillment of a stable source of information aims to keep all parts of the library current and reliable.Keywords: S.R.

Abstract The architecture of a multimedia conceptual design aid, the Concept Database, is presented. The goal of the Concept Database is to provide design teams with easy access to information about life cycle design issues for competing design concepts and access to relevant past designs. The architecture builds on our previous experience in developing the multimedia design archival system called Design SCRIBE (Structured Capture and Retrieval Information Base for Engineering Design.) Approaches to selectively retrieving descriptions of design concepts and past designs are summarized.

Access To Data

Over the past 30 years we have seen a strong but uncoordinated effort to both increase the availability of numeric materials-property data in electronic media and to make the resultant mass of data more readily accessible and searchable for the end-user engineer. The end user is best able to formulate the question and to judge the utility of the answer for numeric property data inquiries, in contrast to textual or bibliographic data for which information specialists can expeditiously carry out searches.Despite the best efforts of several major programs, there remains a shortfall with respect to comprehensiveness and a gap between the goal of easy access to all the world's numeric databases and what can presently be achieved. The task has proven thornier and therefore much more costly than anyone envisioned, and computer access to data for materials scientists and engineers is still inadequate compared, for example, to the situation for molecular biologists or astronomers. However, progress has been made. More than 100 materials databases are listed and categorized by Wawrousek et al. that address several types of applications including: fundamental research, materials selection, component design, process control, materials identification and equivalency, expert systems, and education. Standardization is improving and access has been made more easy.In the discussion that follows, we will examine several characteristics of available information and delivery systems to assess their impact on the successes and limitations of the available products. The discussion will include the types and uses of the data, issues around data reliability and quality, the various formats in which data need to be accessed, and the various media available for delivery. Then we will focus on the state of the art by giving examples of the three major media through which broad electronic access to numeric properties has emerged: on-line systems, workstations, and disks, both floppy and CD-ROM. We will also cite some resources of where to look for numeric property data.
