Presentació i accés a les revistes electròniques a les universitats catalanes

El treball analitza com organitzen l'accés a les col·leccions de revistes electròniques les biblioteques universitàries catalanes. En concret, s'examina l'existència de pàgines web de revistes electròniques, l'organització, les polítiques d'inclusió d'aquests materials en el catàleg així com els procediments catalogràfics aplicats.

El lenguaje de la interrogación: una gramática formal para la recuperación de la información

El conocimiento del lenguaje de interrogación es una herramienta imprescindible para la recuperación de información. En este artículo se ofrece una gramática formal (sintaxis y semántica) para ese tipo de lenguaje. Esta gramática nos permite, por un lado, conocer el lenguaje de interrogación desde un plano sistemático y conceptual y, por otro lado, nos permite obtener ciertos beneficios prácticos de tipo sintáctico y de tipo semántico relacionados con los procesos de recuperación de información.

Semantic domains and supersens tagging for domain-specific ontology learning

In this paper we propose a novel unsupervised approach to learning domain-specific ontologies from large open-domain text collections. The method is based on the joint exploitation of Semantic Domains and Super Sense Tagging for Information Retrieval tasks. Our approach is able to retrieve domain specific terms and concepts while associating them with a set of high level ontological types, named supersenses, providing flat ontologies characterized by very high accuracy and pertinence to the domain.

Medicaid Value Management Program SFY 2008 Report Executive Summary, 2007

In June, 2007, the Commonwealth Fund released a report entitled, “Aiming Higher: Results from a State Scorecard on Health System Performance.” The report ranked states’ health care performance based upon four areas: access, quality, potentially avoidable use of hospitals and costs of care, and healthy lives. Iowa was ranked second overall and was the only state to rank in the top 25 percent on each of the four measures.1 Coupling the HEDIS measures and CAHPS survey results with the Commonwealth report outcomes provides additional information for determining how the state performs with regard to the health care system, in general, and the Medicaid program specifically. For the past five years the results of eight outcome measures encompassing children and adults, and preventive, chronic and acute care have been reported by the University of Iowa Public Policy Center (PPC). The PPC is the independent evaluator for the Medicaid managed care programs and assists the state in an effort to understand the process of care within the Medicaid program. Seven of the eight measures are recommended by the Centers for Medicare and Medicaid, while the eighth, annual dental visit, is used in recognition of the challenges found in providing dental care to Medicaid‐enrolled children and adults.

Leadership Development Opportunities, January 2010

This Guide summarizes some of the many opportunities and experiences available to Iowa youth to enhance their leadership potential and to exercise their leadership abilities. This information was compiled at the request of the Youth Planning Committee for the Governor’s Youth Leadership and Mentoring Conference in 1999 and has continued through the Iowa Collaboration for Youth Development. Although not an exhaustive listing, the Guide provides information on many of the state and national leadership development opportunities for middle and high school youth throughout Iowa. Contact information for each program is provided for those wanting to learn more about the opportunities summarized in the Guide. Recommendations for program additions for future publication of this Guide are welcome.

Proposta i implementació d'un motor de recuperació d'informació especialitzat en dret d'estrangeria (Codex)

CODEX SEARCH és un motor de recuperació d'informació especialitzat en dret d'estrangeria que està basat en eines i coneixement lingüístics. Per a desenvolupar un SRI (sistema de recuperació d'informació) eficient en el domini indicat no n'hi ha prou amb emprar un model tradicional de RI (recuperació d'informació), és a dir, comparar els termes de la pregunta amb els de la resposta, bàsicament perquè no expressen implicacions. En aquest sentit, la solució lingüística proposada es basa a incorporar el coneixement dels especialistes mitjançant la integració en el sistema d'una llibreria de casos. Els casos són exemples de procediments aplicats per experts/ertes en la solució de problemes que han ocorregut en la realitat i que han acabat en èxit o fracàs. Els resultats obtinguts en aquesta primera fase són molt encoratjadors, però és necessari continuar la investigació en aquest camp per millorar el rendiment del prototip.

Application of text-mining for updating protein post-translational modification annotation in UniProtKB.

BACKGROUND: The annotation of protein post-translational modifications (PTMs) is an important task of UniProtKB curators and, with continuing improvements in experimental methodology, an ever greater number of articles are being published on this topic. To help curators cope with this growing body of information we have developed a system which extracts information from the scientific literature for the most frequently annotated PTMs in UniProtKB. RESULTS: The procedure uses a pattern-matching and rule-based approach to extract sentences with information on the type and site of modification. A ranked list of protein candidates for the modification is also provided. For PTM extraction, precision varies from 57% to 94%, and recall from 75% to 95%, according to the type of modification. The procedure was used to track new publications on PTMs and to recover potential supporting evidence for phosphorylation sites annotated based on the results of large scale proteomics experiments. CONCLUSIONS: The information retrieval and extraction method we have developed in this study forms the basis of a simple tool for the manual curation of protein post-translational modifications in UniProtKB/Swiss-Prot. Our work demonstrates that even simple text-mining tools can be effectively adapted for database curation tasks, providing that a thorough understanding of the working process and requirements are first obtained.
