Summary Librarians and patrons searching for reliable health information are fortunate in that this subject area is one for which many reliable, in-depth sites exist. Government, education, and organization sites are, in particular, good sources of information and provide links to other Web pages. It is important, however, for both librarians and their clients to know how to access this information and, especially, how to evaluate the worthiness and usefulness of the information contained therein. 相似文献

ABSTRACT Libraries are quite practiced at outreach activities in the physical world, but now, just as our services and resources have moved online, so must our outreach efforts. This article provides a list of twenty practical things libraries can do to begin to delve into the world of online outreach. Topics covered include listing your library in Wikipedia, listing library events in local community calendars, listing librarians in expert-finding directories, pushing newsletters out via RSS, being present in online game and other environments, and much more. The requirements for online outreach at libraries will always be evolving, but this starter list will provide a place for all libraries to begin their foray into online outreach and marketing. 相似文献

We present three fundamental, interrelated approaches to support multiple access paths to each terminal object in information hierarchies: faceted classification, faceted search, and web directories with embedded symbolic links. This survey aims to demonstrate how each approach supports users who seek information from multiple perspectives. We achieve this by exploring each approach, the relationships between these approaches, including tradeoffs, and how they can be used in concert, while focusing on a core set of hypermedia elements common to all. This approach provides a foundation from which to study, understand, and synthesize applications which employ these techniques. This survey does not aim to be comprehensive, but rather focuses on thematic issues. 相似文献

Frequent requests from users to search engines on the World Wide Web are to search for information about people using personal names. Current search engines only return sets of documents containing the name queried, but, as several people usually share a personal name, the resulting sets often contain documents relevant to several people. It is necessary to disambiguate people in these result sets in order to to help users find the person of interest more readily. In the task of name disambiguation, effective measurement of similarities in the documents is a crucial step towards the final disambiguation. We propose a new method that uses web directories as a knowledge base to find common contexts in documents and uses the common contexts measure to determine document similarities. Experiments, conducted on documents mentioning real people on the web, together with several famous web directory structures, suggest that there are significant advantages in using web directories to disambiguate people compared with other conventional methods. 相似文献

We present a study to develop an improved understanding of symbolic links in web directories. A symbolic link is a hyperlink which makes a directed connection from a webpage along one path through a directory to a page along another path. While symbolic links are ubiquitous in web directories such as Yahoo!, they are under-studied and, as a result, their uses are poorly understood. A cursory analysis of symbolic links reveals multiple uses: to provide navigational shortcuts deeper into a directory, backlinks to more general categories, and multiclassification. We investigated these uses in the Open Directory Project (ODP), the largest, most comprehensive, and most widely distributed human-compiled taxonomy of links to websites, which makes extensive use of symbolic links. The results reveal that while symbolic links in ODP are used primarily for multiclassification, only few multiclassification links actually span top- and second-level categories. This indicates that most symbolic links in ODP are used to create multiclassification between topics which are nested more than two levels deep and suggests that there may be multiple uses of multiclassification links. We also situate symbolic links vis à vis other semantic and structural link types from hypermedia. We anticipate that the results and relationships identified and discussed in this paper will provide a foundation for (1) users for understanding the usages of symbolic links in a directory, (2) designers to employ symbolic links more effectively when building and maintaining directories and for crafting user interfaces to them, and (3) information retrieval researchers for further study of symbolic links in web directories. 相似文献

ABSTRACT This article describes how The Search Engine for Online Historical Directories provides enhanced access for genealogical researchers to valuable family information contained in difficult-to-browse directories that have been made available online by institutions that have not provided sophisticated search tools. 相似文献
