- Abstract
- The purpose of this paper is to identify, describe, evaluate and compare South African search engines, directories and portals. The comparative evaluation entailed analysis of six search engines by means of a checklist of desirable features, as well as a performance test by means of sample searches. The following aspects and features are covered in the checklist: database characteristics, search facilities and techniques, search results and portal services. In the performance test the local search engines were also compared with three international ones. Aardvark was rated the best local search engine judging by its performance in the sample searches, but it was outperformed by two of the international engines, Alta Vista and FAST, with regard to the total number of relevant hits retrieved. The results of the investigation will be of use to searchers in their selection of appropriate search tools and to search engine developers in the process of improving their systems

- Abstract
- In Math-Net stellen Personen und Institutionen ihre für die Mathematik relevanten Informationen auf eigenen Web-Servern bereit, doch sollen die Informationen in einheitlicher Weise erschlossen werden. Dazu gibt es sowohl für Server als auch für die Dokumente Empfehlungen für deren Strukturierung. Die lokalen Informationen werden durch automatische Verfahren gesammelt, ausgewertet und indexiert. Diese Indexe sind die Basis für die Math-Net Dienste. Das sind Search Engines und Portale, die einen qualifizierten und effizienten Zugang zu den Informationen im Math-Net bieten. Die Dienste decken im Gegensatz zu den universellen Suchmaschinen nur den für die Mathematik relevanten Teil des Web ab. Math-Net ist auch ein Informations- und Kornmunikationssystem sowie ein Publikationsmedium für die Mathematik. Die Entwicklung des Math-Net wird von dem breiten Konsens der Mathematiker getragen, den Zugang zu der für die Mathematik relevanten Information zu erleichtern und zu verbessern

- Abstract
- Reviews the exponential growth of Internet resources leading to the emergence of hundreds of Internet directories to organize those resources. Based upon their format, content, and characteristics, these Internet directories are categorized into 8 groups. From one of these groups. 'Subject directories published in professional journals' all published Internet directories are identified and listed in detail. Using Paradox-For-Windows, a comprehensive database of more than 350 of these directories was developed. Analyzes and interprets the data contained in the database and reviews the strengths and weaknesses of print Internet subject directories as compared to online directories and other search engines

- 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
- 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.
