Summary

The emergence of federated search tools for the library market represents a significant step toward the longstanding goal of a common searching interface in the reference environment. These systems aim to provide integrated access to library resources of all types. This article describes and evaluates federated search tools from four vendors. It suggests criteria that may be useful for libraries attempting to compare and contrast this type of access tool.  相似文献

Abstract

The MetaLib Library Portal (MetaLib) is a federated search tool that enables simultaneous searching of multiple electronic resources in a single interface and provides links to resources' native interfaces. Many libraries have already implemented this library portal or various components of it. Prior to launching MetaLib at the University of Florida, the authors conducted a usability study to ensure MetaLib features implemented were appropriate for UF's research community. A total of fifteen faculty researchers and graduate and undergraduate students participated in testing and discussing the product during the spring 2006 semester. This paper illustrates the process used to evaluate MetaLib, which included determining a timeline, developing scenario-based and focus group questions, recruiting participants, and conducting usability tests and focus groups. In addition, the authors describe some of the major findings of the study and the solutions recommended in the formal “Usability Test Report for MetaLib,” and provide an analysis of the challenges associated with usability testing of a federated search tool.  相似文献

OBJECTIVE: The article explores the characteristics of public health information needs and the resources available to address those needs that distinguish it as an area of searching requiring particular expertise. METHODS: Public health searching activities from reference questions and literature search requests at a large, urban health department library were reviewed to identify the challenges in finding relevant public health information. RESULTS: The terminology of the information request frequently differed from the vocabularies available in the databases. Searches required the use of multiple databases and/or Web resources with diverse interfaces. Issues of the scope and features of the databases relevant to the search questions were considered. CONCLUSION: Expert searching in public health differs from other types of expert searching in the subject breadth and technical demands of the databases to be searched, the fluidity and lack of standardization of the vocabulary, and the relative scarcity of high-quality investigations at the appropriate level of geographic specificity. Health sciences librarians require a broad exposure to databases, gray literature, and public health terminology to perform as expert searchers in public health.  相似文献

ABSTRACT

In this study, students' use of a new educational Web portal was evaluated with particular emphasis on searching and browsing strategies. The effects and implications of a federated search system are also discussed. Fifty-four students, ranging from 5th to 12th grade, were given five tasks to complete using the SchoolRooms interface. The tasks required students to use both the search box and the categorical browse feature on the Web portal. Data collected were analyzed to determine time on task, rate of success and the subjects' awareness of success, and the type of search method chosen to complete the tasks. In general, students preferred the search-box strategy to the categorical-browse strategy, but exposure to both strategies resulted in increased use of the browse strategy. Success rates varied widely by task. Students had a difficult time distinguishing between various media and format types returned by the federated search. Results suggest that while students prefer a search-box strategy, it is by no means the only way they search for information. Students experienced difficulty in trying to de-aggregate the results of a federated search engine. These findings have implications for information literacy and library instruction. Forthcoming analysis of these data will address the factors related to search success.  相似文献

Zoological medicine furthers the health and well-being of captive and free-ranging wild animals. Effective information retrieval of the zoological medicine literature demands searching multiple databases, conference proceedings, and organization websites using a wide variety of keywords and controlled vocabulary. Veterinarians, residents, students, and the librarians who serve them must have patience for multiple search iterations to capture the majority of the available knowledge. The complexities of thorough literature searches are more difficult for nondomestic animal clinical cases and research reviews as demonstrated by three search requests involving poisonous snakes, a gorilla, and spiders. Expanding and better disseminating the knowledgebase of zoological medicine will make veterinary searching easier.  相似文献

Peer-to-peer (P2P) networks integrate autonomous computing resources without requiring a central coordinating authority, which makes them a potentially robust and scalable model for providing federated search capability to large-scale networks of text-based digital libraries. However, peer-to-peer networks have so far provided very limited support for full-text federated search with relevance-based document ranking. This paper provides solutions to full-text federated search of text-based digital libraries in hierarchical peer-to-peer networks. Existing approaches to full-text search are adapted and new methods are developed for the problems of resource representation, resource selection, and result merging according to the unique characteristics of hierarchical peer-to-peer networks. Experimental results demonstrate that the proposed approaches offer a better combination of accuracy and efficiency than more common alternatives for federated search of text-based digital libraries in peer-to-peer networks.  相似文献
