The focus of this study was the effect of clustering techniques and query highlighting on search strategy users develop in the virtual environment, and whether position or spatial arrangement influenced user behavior. We found several particularities that can be attributed to the differences in the VR environment.This study's results identify: 1) the need of co-designing both spatial arrangement and interaction method; 2) adifficulty novice users faced when using clusters to identify commontopics; 3) the influence of position and distance on users' selection of collection items to inspect; and 4) that users did not search until found the best match, but only until they found a satisfactory match.","PeriodicalId":42447,"journal":{"name":"Digital Library Perspectives","volume":"61 1","pages":"103-111"},"PeriodicalIF":1.7,"publicationDate":"2000-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90556034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their purpose is to help people do knowledge work, to carry knowledge processes across space and time. DLs are designed, used, and evaluated in a context of work and community. And DLs interact with this context, changing and being changed by it. Effective DLs must be designed and evaluated with a sensitivity to how knowledge is created and understood, and work is done, in a context of knowledge communities, which share practices and tools. DL use is a socially-embedded process. DL development is likewise a complex social process. This panel grows out of a book on social approaches to DL design and evaluation--currrently in press--to which the moderator and each panelist has contributed a chapter. The purpose of the panel is to present socially grounded approaches to understanding DLs; to identify and discuss major issues that arise from these approaches and, more generally, from the social nature of DLs; and to consider implications for the design and evaluation of DLs.","PeriodicalId":42447,"journal":{"name":"Digital Library Perspectives","volume":"17 1","pages":"276-277"},"PeriodicalIF":1.7,"publicationDate":"2000-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85021816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, when scientists need information from other agencies, they must search different digital libraries. To achieve interoperability in this heterogeneous environment, CENDI is piloting the Interagency Digital Library for Science and Engineering for use by federally funded researchers. The federated digital library technology being used in the pilot is Broadsword [2], originally developed by the Air Force Research Laboratory at Rome AFB for use within the intelligence community. It supports interoperability at three key levels: searching across heterogeneous platforms, data structures, and search engines; universal log-on; and government security levels. The CENDI pilot involves databases from three agencies containing over 10 million records. While the initial focus is on bibliographic and full text databases, the system can be extended to include other formats and document types.","PeriodicalId":42447,"journal":{"name":"Digital Library Perspectives","volume":"83 1","pages":"212-213"},"PeriodicalIF":1.7,"publicationDate":"1999-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87125397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Second summit on international cooperation in digital libraries","authors":"R. Akscyn, I. Witten","doi":"10.1145/313238.313455","DOIUrl":"https://doi.org/10.1145/313238.313455","url":null,"abstract":"AGENDA for Summit The agenda for the First Summit -which will serve as the starting point for the Second -was as follows: One of the workshops to be held at Digital Libraries 1999 will be the Second Summit on International Cooperation in Digital Libraries. This workshop follows in the footsteps of the very successful \"First Summit\" held at close of DL98 in Pittsburgh, PA -June 27/28. That meeting brought together 17 researchers, practitioners, and librarians from twelve countries: Canada, China, Denmark, Germany, Japan, Korea, Italy, Mexico, New Zealand, the Netherlands, Singapore, and the United States. The Call for the First Summit, as well as the Report describing its results can be located via ks.com/idla. The text below is a synopsis of that report -and is indicative of our ambitions for the Second Summit. 1. Is international cooperation on digital libraries necessary, and why? 2. What are the truly important benefits of digital libraries and how might they be realized -specifically by international cooperation -while at the same time not being oversold via a never-ending series of grandiose pronouncements? 3. What goals should be set for international cooperation? Who should set them. And how might a critical mass of effort be accumulated to make timely progress? The Summit was motivated by several common beliefs among the attendees. First, that digital libraries are destined for a bright future -indeed, as the Call for the Summit put it: \"Digital Libraries will likely figure amongst the most important and influential institutions of the 21st Century\". Not only will future digital libraries dramatically improve access to the world’s knowledge, but they will also act as \"collaboratories\" out of which new knowledge is crafted and refined by widely-distributed teams and organizations -knowledge that right from conception is fully interconnected with previous work. 4. What organizational mechanisms are appropriate for fostering international cooperation? What other models of internation cooperation have worked and not worked? 5. How will all the cooperating ’participants’ benefit -so that the effort invested is a win-win for all?\" 6. What specific programs and projects should be undertaken, and how can these avoid fragmentation and oneupmanship? 7. How can results be achieved in graduated, incremental steps -versus attempting the ’ever-deadly’ quantum leaps. A second shared belief was that daunting challenges stand in the way of achieving this vision. The difficulties of facing these challenges -to build useable, scaleable, and sustainable digital libraries that interoperate on a global scale -will surely demand genuine collaboration from researchers in many disciplines, as well as substantial commitments from imaginative and resourceful practitioners. 8. What is a realistic time frame for achieving these goals so that unachievable expectations are not spawned in the first place? What might be demonstrable (and heartening) progress in the inter","PeriodicalId":42447,"journal":{"name":"Digital Library Perspectives","volume":"102 1","pages":"267"},"PeriodicalIF":1.7,"publicationDate":"1999-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80586542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ziou, Shengrui Wang","doi":"10.1145/313238.313316","DOIUrl":"https://doi.org/10.1145/313238.313316","url":null,"abstract":"Image retrieval is emerging as an important research area with many applications in various fields such as image and multimedia databases and digital libraries. The World Wide Web is an enormous, distributed, hypermedia and non-structured information system. Tens of millions of images exist on the World Wide Web. Developing tools which would make it possible to seek specific images in this enormous image database is of an unquestionable utility and would give to the WWW all its potential. However, the search for images in the context of the WWW is an extremely difficult task and poses new challenges. Two characteristics are to be taken into account when dealing with images on the WWW: 1. the incredibly large size of all these images and the extraordinary diversity of types of images which one can find on the WWW; 2. in the field of image processing and computer vision, there is no general algorithm able to process all types of images. Two fundamental issues must be addressed when developing retrieval tools: effectiveness of search and effectivity of search. The effectiveness implies that one can find information in a reasonable time. With the power of the current workstations and the development of techniques such as parallel programming and multi-thread programming, the effectiveness is not a bottleneck. However the effectivity of the images retrieved compared to the request is a major problem and should be examined more closely. The majority of the retrieval tools existing on the WWW are not pertinent: many retrieved documents are not pertinent to the request (noise) and many documents pertinent to the request are not retrieved (silence). Taking into account all these facts, we believe that a preliminary and crucial step before developing an image retrieval tool on the WWW is, first, to classify these images in many classes such as photographs, graphics, cartoons, faces, textured images, color images, etc. and then perform a search in each class. Doing so, we take at least two advantages: 1. effectivity is improved (noise and silence are reduced) since search is done in a specific class and not in all the database; 2. we can apply appropriate algorithms on each class of images given that a general algorithm for all types of images does not exist. In this paper, we are interested in performing image search on the WWW using both the image content and textual key-words. The following features are yet available in our system:","PeriodicalId":42447,"journal":{"name":"Digital Library Perspectives","volume":"22 1","pages":"208-209"},"PeriodicalIF":1.7,"publicationDate":"1999-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81743224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
