"Les interfaces graphiques de recherche relèvent presque toutes d'un modèle unique et primaire : un champ de saisie uniligne et un bouton permettant de valider la requête saisie dans le champ. Face à la diversité des individus et de leurs besoins en informations, de nombreuses techniques de visualisation et d'interaction innovantes ont émergés ces dix dernières années. Pourtant ces innovations sont rarement utilisées et le but de cet article est de faire le point sur l'état de l'art des techniques de visualisation et d'interaction qui peuvent être pertinentes pour la recherche d'information."

"Cluuz.com takes results and applies semantic processes to them. Some of the company's display options are a bit too sophisticated for my 64-year-young eyes, but I found the system quite useful. (...) The system offers other ways to view the results set. For example, you can look at hits from the search engines to which the query is passed as a traditional laundry list. Other choices include a cluster display and a Flash display which is, in my opinion, cluttered with sliders, controls, and options."\n"Cluuz technology is incorporated into Sprylogics enterprise products where it provides search and disambiguation capabilities for both internal and external data. Enterprises using Cluuz technology can do a single search for all sources of information that they have access to. The results are pulled from unstructured information from within the firewall and reconciled with the results pulled from the web, thereby forming a complete intelligence picture. This capability allows users to very effectively expand their knowledge on a topic for which they already have information internally."

"Contrairement aux moteurs de recherche fédérée, Summon s'appuie sur un index unique, constamment mis à jour, qui contient les méta-données des ressources que propose la bibliothèque, ce qui garantirait un temps de réponse plus court. Concernant l'affichage des résultats, il se fait « selon leur pertinence », sans que l'on puisse savoir sur quoi cette pertinence est basée. Il semble cependant que l'algorithme traite principalement les métadonnées des notices plutôt que celles du texte intégral pour ne pas générer de bruit. Les résultats sont proposés sous la forme d'un affichage à facettes, avec des possibilités pour affiner sa recherche (tri par contenu, par date, par bibliothèque…), et un fil RSS est proposé sur les résultats de la recherche. Summon est construit sur une architecture logicielle « libre » (Lucene). Rien n'est à installer « en dur » localement, tout est hébergé sur les serveurs de SerialsSolutions (Seattle, WA). Summon bénéficie de la puissance de feu de ProQuest-CSA (métadonnées de Ulrich's) et a passé des accords avec de nombreux éditeurs pour proposer aujourd'hui un index riche de plus de 500 millions de documents indexés, provenant de plus de 70 000 périodiques et plus de 100 fournisseurs de contenus dans sa base de connaissance. L'interrogation des bases d'archives ouvertes est possible."

""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)."

"RDA sera peut-être le format de catalogage de demain. Basé sur les FRBR et les FRAR, RDA se donne les objectifs suivants : * Fournir un "framework" fiable et souple pour décrire à la fois le contenu et les aspects techniques de tous types de ressources et de documents * Etre compatible avec des principes, modèles et standards internationaux * Etre utilisable hors de la communauté des bibliothèques, et que des communautés variées puissent l'adapter à leurs besoins spécifiques.

"This editorial aims to introduce a special issue of Library Hi Tech on "Virtual research environments: issues and opportunities for librarians". It defines the concept of the virtual research environment (VRE), describes its relationship both to the virtual learning environment and to Web 2.0, and proposes that librarians play a central role in VRE development and use. "

"Many Web 2.0 services (including Library 2.0 catalogs) make use of folksonomies. The purpose of this paper is to cut off all tags in the long tail of a document-specific tag distribution. The remaining tags at the beginning of a tag distribution are considered power tags and form a new, additional search option in information retrieval systems. In a theoretical approach the paper discusses document-specific tag distributions (power law and inverse-logistic shape), the development of such distributions (Yule-Simon process and shuffling theory) and introduces search tags (besides the well-known index tags) as a possibility for generating tag distributions."

"For more than 15 years, Index Data has built technologies and solutions in support of searching. Our customers and partners include national libraries and consortia, government agencies, and commercial companies. Our business is to seek out the most challenging problems in the area of metasearching and large-scale content indexing and searching, and to engineer industrial-strength tools to help people solve those problems. We have been active participants in and contributors to the international standards communities in our field since the very beginning. Our open-source protocol implementations are the most widely used in the industry and have had significant impact on both the evolution and penetration of international standards like Z39.50 and SRU. Because of our long history in this area, and our focus on building flexible, reusable tools for developers and organizations, our partners can focus their attention on adding value and on creating compelling user experiences. "

a compilation of chapters by 25 librarians around the world who have used mashups within their organisations to improve services to their patrons. Each chapter includes first-hand experiences and tips for using outside data sources to enhance library offerings.

"(...) We list here some of the search and retrieval, content and other features that might be expected from a resource discovery system and which of the four systems (WCL, Encore, Summon, LibraryFind™) provide that functionality."

"Librarians, teachers and parents have told us how hard it is for students to understand web searching. Boolify makes it easier for students to understand their web search by illustrating the logic of their search, and by showing them how each change to their search instantly changes their results. It's simple, immediate and easy to use with your class or in your library. Search results are presented through Google's "Safe Search STRICT" technology. There are two important caveats: a) no filtering technology is 100% secure, as this blog posting astutely points out and 2) we are unable to control or modify the results that we provide, beyond the filtering settings available through Google."

"Next-generation library catalogs have been getting good press for some time now. While uptake of these search tools has increased over the last year, next-gen OPACs are by no means ubiquitous yet. While the market continues to evolve, the marketplace for these products has matured significantly, with a fairly wide range of products available, both commercial and open source."

"Many libraries are now designing and implementing their own tools to meet users' needs for search and data discovery. The aim of this study is to share the experiences of the HAM-TMC Library, one of the largest US medical libraries, in creating and implementing such a tool. Many libraries accept federated search and other technologies directly from their library management system vendors as the simplest way to proceed with implementing new technologies. The HAM-TMC Library recognized that its particular information environment required learning the "problem space" thoroughly before investigating available options. As a result, the new tool the Library is providing is much more likely to meet specific user information needs."

"What's really hard about real-time search is figuring out the meaning and value of those fleeting bits of information. The challenge goes beyond filtering out spam, though that's an important part of it. People who search real-time data want the same quality, authority, and relevance that they expect when they perform traditional Web searches. Nobody wants to drink straight from a fire hose."

"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.
