"The Wayne State Library System launched its library mapping application in February 2010, designed to help locate materials in the five WSU libraries. The system works within the catalog to show the location of materials, as well as provides a web form for use at the reference desk. Developed using PHP and MySQL, it requires only minimal effort to update using a unique call number overlay mechanism. In addition to mapping shelved materials, the system provides information for any of the over three hundred collections held by the WSU Libraries. Patrons can do more than just locate a book on a shelf: they can learn where to locate reserve items, how to access closed collections, or get driving maps to extension center libraries. The article includes a discussion of the technology reviewed and chosen during development, an overview of the system architecture, and lessons learned during development."

"Zebra is a high-performance, general-purpose structured text indexing and retrieval engine. It reads structured records in a variety of input formats (eg. email, XML, MARC) and allows access to them through exact boolean search expressions and relevance-ranked free-text queries. Zebra supports large databases (more than ten gigabytes of data, tens of millions of records). It supports incremental, safe database updates on live systems. You can access data stored in Zebra using a variety of Index Data tools (eg. YAZ and PHP/YAZ) as well as commercial and freeware Z39.50 clients and toolkits. Zebra is free software, available under the GPL license."

"What we are about to get is a Social Relevancy Rank. Whenever you search streams of activity, the results will be ordered not chronologically but by how relevant each is to you based on your social graph. That is, people who matter more to you will bubble up. How does this work? Well, there will be a formula, just as there is a formula for Page Rank."

"SOPHIA has been designed to address these recognised limitations. SOPHIA is unique in that it addresses the 'search problem' from a linguistic view point as opposed to from a purely mathematical perspective. It is based on an established model of language called Semiotics which describes how we understand and interpret the meaning of signs and texts in context. We don't argue that SOPHIA should replace Boolean search entirely - moreover it is a complementary tool that provides an enriched search experience that enables users to browse, navigate, discover and understand their information in context. SOPHIA has a 3-tier architecture designed for OEM and ease of integration with Development Partners. Contact sales@sophiasearch.com to explore Working Together on a project or application that can be enhanced and developed by a relationship with SOPHIA's semantic search technology."

"Jumper 2.0 is a revolution in enterprise search. One that delivers personalized, specialized, and trusted search directly to the knowledge workers who need it most. Jumper is light-weight, web-based, license-free, and quickly deployed to smaller groups of users. Easily customized and adaptable it meets the unique needs of departments and divisions, research groups and project teams. Making it a point solution search approach that is highly flexible and very dynamic. Jumper 2.0 is commercial open source software for universal search and knowledge management powered by an enterprise bookmarking engine. Jumper uses peer and social-networking principles to tag and link distributed content, media, or data regardless of format or location - including databases, flat files, fileshares, content systems, blogs and wikis, even people - through one simple search box."

"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."

"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.

"(...) the relevancy ranking within Summon is based on term frequencies as Aaron said, but many other algorithms are used as well, such as field weightings and inverse term frequencies to counterbalance any skewing from the full text content. Additionally, each record in Summon has a static rank that allows for balancing records from one collection against another to ensure all records are treated equally. "
