- Abstract
- A unique collection of historical material covering the lives and events of an English village between 1400 and 1750 has been made available via a WWW enabled information retrieval system. Since the expected readership of the documents ranges from school children to experienced researchers, providing this information in an easily accessible form has offered many challenges requiring tools to aid searching and browsing. The file structure of the document collection was replaced by an database, enabling query results to be presented on the fly. A Java interface displays each user's context in a form that allows for easy and intuitive relevance feedback

- Abstract
- Extends the WWW hypertext search paradigm to allow flexible conceptual navigation of online databases. Using the WWW Common Gateway Interface standard and natural language processing techniques. The WEBLINE Virtual Hypertext Saerch interface prototype automatically identifies noun phrases in retrieved records and it converts them into dynamic hotlinks and search strategies to support associative hypertext browsing of MEDLINE and other NLM databases. The approach is applicable to the searching of online databases in general and can be broadened to implement virtual hypertext searching of the Virtual WWW

- Abstract
- Despite the development of huge healthcare Web sites and powerful search engines, many searchers end their searches prematurely with incomplete information. Recent studies suggest that users often retrieve incomplete information because of the complex scatter of relevant facts about a topic across Web pages. However, little is understood about regularities underlying such information scatter. To probe regularities within the scatter of facts across Web pages, this article presents the results of two analyses: (a) a cluster analysis of Web pages that reveals the existence of three page clusters that vary in information density and (b) a content analysis that suggests the role each of the above-mentioned page clusters play in providing comprehensive information. These results provide implications for the design of Web sites, search tools, and training to help users find comprehensive information about a topic and for a hypothesis describing the underlying mechanisms causing the scatter. We conclude by briefly discussing how the analysis of information scatter, at the granularity of facts, complements existing theories of information-seeking behavior.

- Abstract
- Consumer empowerment and the role of the expert patient in their own healthcare, enabled through timely access to quality information, have emerged as significant factors in better health and lifestyle outcomes. Governments, medical researchers, healthcare providers in the public and private sector, drug companies, health consumer groups, and individuals are increasingly looking to the Internet to both access and distribute health information, communicate with each other, and form supportive or collaborative online communities. Evaluating the accuracy, provenance, authority, and reliability of Web-based health information is a major priority. The Breast Cancer Knowledge Online Portal project (BCKOnline) explored the individual and changing information and decision support needs of women with breast cancer and the issues they face when searching for relevant and reliable health information on the Internet. Its user-sensitive research design integrated multidisciplinary methods including user information-needs analysis, knowledge-domain mapping, metadata modeling, and systems-development research techniques. The main outcomes were a personalized information portal driven by a metadata repository of user-sensitive resource descriptions, the BCKOnline Metadata Schema, richer understandings of the concepts of quality, relevance, and reliability, and a user-sensitive design methodology. This article focuses on the innovative, metadata-based quality reporting feature of the BCKOnline Portal, and concludes that it is timely to consider the inclusion of quality elements in resource discovery metadata schema, especially in the health domain.

- Abstract
- The growing number of networked information resources and services offers unprecedented opportunities for delivering high quality information to the computer desktop of a wide range of individuals. However, currently there is a reliance on a database retrieval model, in which endusers use keywords to search large collections of automatically indexed resources in order to find needed information. As an alternative to the database retrieval model, this paper outlines the classical digital library model, which is derived from traditional practices of library and information science professionals. These practices include the selection and organization of information resources for local populations of users and the integration of advanced information retrieval tools, such as databases and the Internet into these collections. To evaluate this model, library and information professionals and endusers involved with primary care medicine were asked to respond to a series of questions comparing their experiences with a digital library developed for the primary care population to their experiences with general Internet use. Preliminary results are reported

- Abstract
- As more people gain at-home access to the Internet, information seeking an the Web has become embedded in everyday life. The objective of this study was to characterize the home as an information use environment and to identify a range of information seeking and Websearch behaviors at home. Twelve Northern California residents were recruited, and the data were collected through semi-structured at-home interviews based an a self-reported Search Activities Diary that subjects kept over a 3-5 day period. The data were analyzed an four levels: home environment, information seeking goals, information retrieval interaction, and search query. Eindings indicated that the home, indeed, provided a distinct information use environment beyond physical setting alone in which the subjects used the Web for diverse purposes and interests. Based an the findings, the relationships among home environment, Web context, and interaction situation were identified with respect to user goals and information-seeking behaviors.

- Abstract
- Das Informationsangebot im Bereich der Agrarwissenschaft hat sich seit Einführung des Internet sehr stark verändert. Vor einigen Jahren war die Suche nach agrarwissenschaftlichen Themen im Wesentlichen noch auf die Suche nach Fachliteratur beschränkt. Dabei standen die Kataloge der landwirtschaftlichen Bibliotheken als auch Fachinformationsstellen, die nach Auftrag mit Hilfe spezieller Retrieval-Software in Online-Datenbanken recherchierten, zur Verfügung. Heute kann der Interessierte von jedem PC aus selbstständig in Online-Datenbanken suchen, ohne tief greifende Kenntnisse der Retrieval-Software zu besitzen, und er erhält darüber hinaus noch weitergehende Informationen. Agrarrelevante Firmen, Organisationen oder auch Einzelanbieter informieren über aktuelle landwirtschaftliche Themen, bieten so genannte "Agrar-Chats" an, geben Tipps für Verbraucher und Landwirte, stellen einen Zugang zu Agrarbörsen usw. Die Informationsangebote im Agrarbereich werden von zahlreichen Institutionen bereitgestellt, die in diesem Bereich tätig sind. Auf der einen Seite sind das Verwaltungseinrichtungen der Agrarwirtschaft und Forschungseinrichtungen des Bundes und der Länder, auf der anderen Seite Industrieverbände, Firmen, Organisationen, Einzelanbieter wie auch landwirtschaftliche Verlage sowie landwirtschaftliche Bibliotheken

- Abstract
- Confirms the accuracy of a prediction 4 years ago that the CD-ROM graphic interfaces then available would be rivalled in online. Many Web based services now outperform CD-ROM models and magazine pages often look better on the Web than on CD-ROM. Desirable, but not widely available, is the facility to download data from CD-ROM databases. The best CD-ROM authority and retrieval software packages with impressible capabilities remain expensive but there are reasonably priced alternatives for Web publishing and database searching, many of which are derived from CD-ROM originals. A new software development which allows replication of Web sites on CD-ROM will feature in articles in future issues of 'Information today'

- Abstract
- All types of information can be referenced to a geographic place. Maps, aerial photographs, and remote sensing images are spatially georeferenced. Other forms of information such as books, articles, research papers, pieces of music, and art are often linked to a geographic location through place names (geographic names). A gazetteer (a dictionary of geographic names) that is spatially referenced itself provides the bridge between these two types of georeferencing. With a georeferenced gazetteer translation service, a user can start with a geographic name and find information that is described with either geographic names or with geospatial coordinates. Use of this powerful indirect geospatially referencing tool can be applied as a common approach to libraries, bibliographic files, data centers, web resources, and museum and specimen collections and can be particular useful across language barriers since latitude and longitude coordinates are universally understood. The Alexandria Digital Library has implemented a gazetteer component for its georeferenced digital library. This experience resulted in the creation of a Gazetteer Content Standard, a Feature Type Thesaurus, and an operational interactive gazetteer service. This paper describes the development of these components and illustrates the use of this tool in a georeferenced digital library. It also relates progress in working with Federal agencies and others toward developing shareable gazetteer data through Digital Gazetteer Information Exchange programs

- Abstract
- Describes a WWW based system which allows users to view, search and post geographically indexed information of the Earth. 2 geographic browsers have been developed: a 2D map browser capable of continuous scroll and zoom of an arbitrarily large sheet and a 3D flight-simulator browser capable of continuous flight around the Earth. On the server side, a geographical and geometrical server has been developed which contains large databases of images, elevations, lines, points and polygons stored in tiles structured into hierarchical pyramids or quadtrees. A metadata server has also been developed which contains URL pointers and geographical coordinates of various WWW documents, geographical information and geometrical models

- Abstract
- Hundreds of scholarly studies have investigated various aspects of Wikipedia. Although a number of literature reviews have provided overviews of this vast body of research, none has specifically focused on the readers of Wikipedia and issues concerning its readership. In this systematic literature review, we review 99 studies to synthesize current knowledge regarding the readership of Wikipedia and provide an analysis of research methods employed. The scholarly research has found that Wikipedia is popular not only for lighter topics such as entertainment but also for more serious topics such as health and legal information. Scholars, librarians, and students are common users, and Wikipedia provides a unique opportunity for educating students in digital literacy. We conclude with a summary of key findings, implications for researchers, and implications for the Wikipedia community.

- Abstract
- Reading is a common everyday activity for most of us. In this article, we examine the potential for using Wikipedia to fill in the gaps in one's own knowledge that may be encountered while reading. If gaps are encountered frequently while reading, then this may detract from the reader's final understanding of the given document. Our goal is to increase access to explanatory text for readers by retrieving a single Wikipedia article that is related to a text passage that has been highlighted. This approach differs from traditional search methods where the users formulate search queries and review lists of possibly relevant results. This explicit search activity can be disruptive to reading. Our approach is to minimize the user interaction involved in finding related information by removing explicit query formulation and providing a single relevant result. To evaluate the feasibility of this approach, we first examined the effectiveness of three contextual algorithms for retrieval. To evaluate the effectiveness for readers, we then developed a functional prototype that uses the text of the abstract being read as context and retrieves a single relevant Wikipedia article in response to a passage the user has highlighted. We conducted a small user study where participants were allowed to use the prototype while reading abstracts. The results from this initial study indicate that users found the prototype easy to use and that using the prototype significantly improved their stated understanding and confidence in that understanding of the academic abstracts they read.

- Abstract
- Controversy is a complex concept that has been attracting attention of scholars from diverse fields. In the era of Internet and social media, detecting controversy and controversial concepts by the means of automatic methods is especially important. Web searchers could be alerted when the contents they consume are controversial or when they attempt to acquire information on disputed topics. Presenting users with the indications and explanations of the controversy should offer them chance to see the "wider picture" rather than letting them obtain one-sided views. In this work we first introduce a formal model of controversy as the basis of computational approaches to detecting controversial concepts. Then we propose a classification based method for automatic detection of controversial articles and categories in Wikipedia. Next, we demonstrate how to use the obtained results for the estimation of the controversy level of search queries. The proposed method can be incorporated into search engines as a component responsible for detection of queries related to controversial topics. The method is independent of the search engine's retrieval and search results recommendation algorithms, and is therefore unaffected by a possible filter bubble. Our approach can be also applied in Wikipedia or other knowledge bases for supporting the detection of controversy and content maintenance. Finally, we believe that our results could be useful for social science researchers for understanding the complex nature of controversy and in fostering their studies.
