"Randomly selected undergraduates at Brigham Young University, Brigham Young University-Idaho, and Brigham Young University-Hawaii, all private universities sponsored by The Church of Jesus Christ of Latter-day Saints, participated in a study that investigated four questions regarding federated searching: (1) Does it save time? (2) Do undergraduates prefer it? (3) Are undergraduates satisfied with the results they get from it? (4) Does it yield higher-quality results than nonfederated searching? Federated searching was, on average, 11 percent faster than nonfederated searching. Undergraduates rated their satisfaction with the citations gathered by federated searching 17 percent higher than their satisfaction using nonfederated search methods. A majority of undergraduates, 70 percent, preferred federated searching to the alternative. This study could not ultimately determine which of the two search methods yielded higher citation quality. The study does shed light on assumptions about federated searching and will interest librarians in different types of academic institutions, given the diversity of the three institutions studied."

"(...) Les pages qui suivent, issues d'un travail d'étude mené au SCD de l'IUFM de Lyon 1, veulent tenter d'apporter quelques premiers éclairages aux collègues confrontés à ces questions. Dans ce dessein, ces lignes reviendront d'abord rapidement sur ce qu'est un ENT avant de préciser quelles raisons plaident pour que les bibliothèques s'intègrent dans un ENT. L'importante question organisationnelle sera ensuite évoquée, avant qu'une proposition de phasage n'ouvre des horizons plus concrets."

"Ce billet est l'émanation d'une 'synthèse bibliographique' menée dans le cadre d'un travail de groupe de : Daniel B, Pascal K, et David S. Le rapport finalisé arrive bientôt sur vos écrans…"

"Le Northern Ireland Science Park vient de décerner le prix de l'année aux chercheurs de l'Université d'Ulster pour le développement de SOPHIA, un outil de recherche réalisé en collaboration avec l'Université de St Petersbourg en Russie. La recherche initiale du projet a été effectuée au Northern Ireland Knowledge Engineering Lab (NIKEL), qui fait partie de la University's School of Computing and Mathematics. Le but de cet outil de recherche est de donner des résultats qui sont fondés sur le sens des mots-clés et non pas sur les mots eux-mêmes. SOPHIA, pour SOPHisticated Information Analysis, analyse et traite chaque document comme s'il était composé de centaines de milliers de documents. Elle structure chaque partie du document en l'associant à un thème. Les documents sont reliés entre eux en se fondant sur des thèmes communs. Les différents thèmes sont détectés automatiquement sans aucune intervention humaine. Avec ce système, la réponse à une requête peut ne contenir aucun des mots clés de la requête mais uniquement des documents sur le même sujet."

"Le concept des Swickis, plus ancien que les outils vus précédemment, est identique à celui de ses principaux concurrents avec une interface permettant de créer de façon très complète son propre moteur de recherche vertical (voir encadré page 14). A noter que, en mode simple en mode avancé chez Eurekster, les possibilités de configuration sont excellentes : liste d'url à inclure ou à exclure, thématiques générales, mots clés, filtre sur les contenus adultes, recherches multimédia, ajout de nuages de requêtes, etc. La technologie de recherche utilisée est celle de Yahoo! (Yahoo! Search Technology)."

""In this current phase of library automation, all eyes are focused on developing and deploying Web-based interfaces better suited to meet the expectations of the current generation of Web-savvy users," notes Marshall Breeding in the "Introduction" to "Next-Generation Library Catalogs," the fourth issue of Library Technology Reports in 2007. "Over the course of the last year, a number of libraries have made bold moves to introduce new catalogs cast in a mold apart from their previous offerings. Library automation vendors have launched development efforts to create new catalogs and interfaces more in tune with today's expectations," Breeding adds. In this issue of LTR, Breeding covers the terminology associated with the "next-generation" catalog situation as well as such areas as: * federated searching and * other features expected in the "next-generation" interfaces (such as faceted navigation, relevancy, the "did you mean?" feature, and RSS)."

"In 2007-2008, the DLF convened a Task Group to recommend standard interfaces for integrating the data and services of the Integrated Library System (ILS) with new applications supporting user discovery. This page gives access to the group's recommendation, related materials, and information on followup activities."

"The Web puzzle of online information resources often hinders end-users from effective and efficient access to these resources. Clustering resources into appropriate subject-based groupings may help alleviate these difficulties, but will it work with heterogeneous material? The University of Michigan and the University of California Irvine joined forces to test automatically enhancing metadata records using the Topic Modeling algorithm on the varied OAIster corpus. We created labels for the resulting clusters of metadata records, matched the clusters to an in-house classification system, and developed a prototype that would showcase methods for search and retrieval using the enhanced records. Results indicated that while the algorithm was somewhat time-intensive to run and using a local classification scheme had its drawbacks, precise clustering of records was achieved and the prototype interface proved that faceted classification could be powerful in helping end-users find resources.

"The Engines win by a landslide, at least according to current college students. They preferred searching on Google or Yahoo versus their college library systems, based on the attributes of: speed (90%); convenience (84%); ease of use (87%); cost-effectiveness (71%); and reliability (63%). Libraries, however, won on more trustworthy measures including credibility (77%) and accuracy (76%). While students prefer library sources, they also heavily count on the engines. Over half (53%) say the results from engines are as trustworthy as libraries. Google, Yahoo and Ask all rank about the same, without much differentiation."

"Depuis que j'ai mentionné ici l'achat d'un résolveur de liens OpenURL, je reçois, tous les 2 ou 3 jours, un mail me demandant comment nous avons choisi. Je mets la réponse ici (hors questions tarifaires, bien sûr). Je me suis appuyé sur l'article de Ross Singer dans Computers in Libraries de février 2006: Helping you buy: link resolver tools."
