- Abstract
- 'Quality-controlled subject gateways' are Internet services which apply a rich set of quality measures to support systematic resource discovery. Considerable manual effort is used to secure a selection of resources which meet quality criteria and to display a rich description of these resources with standards-based metadata. Regular checking and updating ensure good collection management. A main goal is to provide a high quality of subject access through indexing resources using controlled vocabularies and by offering a deep classification structure for advanced searching and browsing. This article provides an initial empirical overview of existing services of this kind, their approaches and technologies, based on proposed working definitions and typologies of subject gateways

- Abstract
- Reports a preliminary analysis of organizational schemes applied by academic libraries worldwide to arrange their electronic resources an their Web-based information gateways. The unsystematic sample consists of 41 academic libraries in 10 countries representing 4 languages, Chinese, English, German, and Spanish. The study reveals a widely accepted practice in applying 6 simplistic methods to organizing online information: by resource type, alphabetical by title, alphabetical by subject (mostly discipline and genre), by vendor/publisher, by broad classification, and random. In addition, it notes a marked difference between libraries in the English-speaking world and those in other countries in that the former present significantly more systematic characteristics.

- Abstract
- Under the auspices of the Desire II project, researchers at NetLab and OCLC are providing searching and browsing of a test collection of engineering documents on the Web. The goal of the project is to explore simple methods of automatic classification to provide subject browsing of a robot-generated engineering index. At NetLab the documents are automatically classified and organized using an engineering-specific scheme, the Engineering Index (Ei) Thesaurus and Classification; at OCLC the Dewey Decimal Classification (DDC), a general knowledge organization scheme, is being used

- The key political and strategic issues which needs to be addressed for the future development of the Australian subject gateways are: continued quality of content creation, integration of access to print and electronic resources, archiving and persistent identification, sustainability of services and service integration. These issues will be more effectively tackled internationally, and the Australian subject gateways are keen to work with international collaborators to achieve a mutually beneficial outcome

- Abstract
- Project SSG-FI at SUB Göttingen provides special subject gateways to international high quality Internet resources for scientific users. Internet sites are selected by subject specialists and described using an extension of qualified Dublin Core metadata. A basic evaluation is added. These descriptions are freely available and can be searched and browsed. These are now subject gateways for 3 subject ares: earth sciences (GeoGuide); mathematics (MathGuide); and Anglo-American culture (split into HistoryGuide and AnglistikGuide). Together they receive about 3.300 'hard' requests per day, thus reaching over 1 million requests per year. The project SSG-FI behind these guides is open to collaboration. Institutions and private persons wishing to contribute can notify the SSG-FI team or send full data sets. Regular contributors can request registration with the project to access the database via the Internet and create and edit records

- Abstract
- The article focuses on the EBSCO databases that provide services to libraries. The Library, Information Science and Technology Abstracts (LISTA) include resources focusing on librarianship, classification, cataloging, bibliometrics, online information retrieval, and information science. LISTA has more than 21,000 articles from more than 600 periodicals and includes more than 5,000 conference papers and reports. In the database, there are also cited references and the number of times the source was used can also be found within the database. These are helpful tips in bibliography researching. The database has also several search options including "Basic Search," "Advanced Search," and Indexes." The EBSCOhost interface is simple to use and easy to grasp while LISTA is a free abstract database.

- Abstract
- The large number and variety of online databases in the field of environment sciences and chemistry underlies the need for a cooperative evaluation approach. Presents 2 evaluation criteria, divided into 4 headings; general criteria (size of data source, cost of 1 hour searching, updating of database, availability on other media); chemical relevant criteria (number of chemicals, identification parameters of chemicals, test set chemicals, development of chemicals), environmental relevant criteria (information parameters for chemicals, parameter development); and criteria describing environmental chemicals (use of chemicals, quality of database). A 6 number scoring system is applied to these criteria and the Hasse diagram technique is presented for 19 bibliographic online databases using these criteria. Using this technique, 'good' and 'bad' databases are identified and changes in the database content from 1995 to 1998 can be visualized

- Abstract
- Wissenschaftliche Informationen im Internet gewinnen zunehmend an Bedeutung. Um sie als zuverlässige Ressourcen für die wissenschaftliche Arbeit zu erschließen, müssen sie auf ihre Qualität geprüft werden - eine Aufgabe, die vermehrt von wissenschaftlichen Bibliotheken über ihre Internetdienste wie Subject Gateways, Digitale oder Virtuelle Bibliotheken wahrgenommen wird. Der vorliegende Artikel bietet eine medientheoretische Diskussion zum wissenschaftlichen Informationsraum im Internet und den medienbedingten Auswirkungen auf die Inhalte sowie einen Überblick zur Entwicklung von Evaluationsansätzen für Internetressourcen. Die theoretischen Abhandlungen werden durch einen umfangreichen Serviceteil ergänzt, der detailliert Qualitätskriterien und den Evaluierungsprozess in einer Weise aufzeigt, welche die Anpassung an (fach-)spezifische Anforderungen ermöglicht.

- Abstract
- Since their inception in the early 1960s the strength and unique aspect of the ISI citation indexes has been their ability to illustrate the conceptual relationships between scholarly documents. When authors create reference lists for their papers, they make explicit links between their own, current work and the prior work of others. The exact nature of these links may not be expressed in the references themselves, and the motivation behind them may vary (this has been the subject of much discussion over the years), but the links embodied in references do exist. Over the past 30+ years, technology has allowed ISI to make the presentation of citation searching increasingly accessible to users of our products. Citation searching and link tracking moved from being rather cumbersome in print, to being direct and efficient (albeit non-intuitive) online, to being somewhat more user-friendly in CD format. But it is the confluence of the hypertext link and development of Web browsers that has enabled us to present to users a new form of citation product -- the Web of Science -- that is intuitive and makes citation indexing conceptually accessible. A cited reference search begins with a known, important (or at least relevant) document used as the search term. The search allows one to identify subsequent articles that have cited that document. This feature adds the dimension of prospective searching to the usual retrospective searching that all bibliographic indexes provide. Citation indexing is a prime example of a concept before its time - important enough to be used in the meantime by those sufficiently motivated, but just waiting for the right technology to come along to expand its use. While it was possible to follow citation links in earlier citation index formats, this required a level of effort on the part of users that was often just too much to ask of the casual user. In the citation indexes as presented in the Web of Science, the relationship between citing and cited documents is evident to users, and a click of the mouse is all it takes to follow a citation link. Citation connections are established between the published papers being indexed from the 8,000+ journals ISI covers and the items their reference lists contain during the data capture process. It is the standardized capture of each of the references included with these documents that enables us to provide the citation searching feature in all the citation index formats, as well as both internal and external links in the Web of Science.

- 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
- 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.

- Abstract
- Currently, web document repositories have been collaboratively created and edited. One of these repositories, Wikipedia, is facing an important problem: assessing the quality of Wikipedia. Existing approaches exploit techniques such as statistical models or machine leaning algorithms to assess Wikipedia article quality. However, existing models do not provide satisfactory results. Furthermore, these models fail to adopt a comprehensive feature framework. In this article, we conduct an extensive survey of previous studies and summarize a comprehensive feature framework, including text statistics, writing style, readability, article structure, network, and editing history. Selected state-of-the-art deep-learning models, including the convolutional neural network (CNN), deep neural network (DNN), long short-term memory (LSTMs) network, CNN-LSTMs, bidirectional LSTMs, and stacked LSTMs, are applied to assess the quality of Wikipedia. A detailed comparison of deep-learning models is conducted with regard to different aspects: classification performance and training performance. We include an importance analysis of different features and feature sets to determine which features or feature sets are most effective in distinguishing Wikipedia article quality. This extensive experiment validates the effectiveness of the proposed model.
