Keywords given by authors of scientific articles in database descriptors

This paper analyses the keywords given by authors of scientific articles and the descriptors assigned to the articles in order to ascertain the presence of the keywords in the descriptors. 640 INSPEC, CAB abstracts, ISTA and LISA database records were consulted. After detailed comparisons it was found that keywords provided by authors have an important presence in the database descriptors studied, since nearly 25% of all the keywords appeared in exactly the same form as descriptors, with another 21% while normalized, are still detected in the descriptors. This means that almost 46% of keywords appear in the descriptors, either as such or after normalization. Elsewhere, three distinct indexing policies appear, one represented by INSPEC and LISA (indexers seem to have freedom to assign the descriptors they deem necessary); another is represented by CAB (no record has fewer than four descriptors and, in general, a large number of descriptors is employed; in contrast, in ISTA, a certain institutional code towards economy in indexing, since 84% of records contain only four descriptors

Análisis bibliométrico de la producción científica de la Universidad Politécnica de Valencia 1973-2001

Se presenta la proyección de la Universidad Politécnica de Valencia mediante el análisis de su producción científica desde 1973 hasta 2001 inclusive, a partir de los artículos de revista y las comunicaciones a congresos disponibles en las principales bases de datos nacionales e internacionales. Se ha analizado la productividad y distribución temporal, por tipo de documento y por idioma, así como la producción científica por autores y por departamentos, identificando los más productivos. Por otro lado, se ha estudiado la distribución y evolución de la literatura científica, indicando aquellas revistas más utilizadas. Los resultados indican, como aspectos más relevantes, una amplia gama de áreas temáticas cubiertas, el incremento anual constante de la productividad científica, así como una amplia presencia en las revistas con factor impacto.This article studies the scope of Polytechnic University of Valencia through the analysis of its scientific output since 1973 until 2001 based on the journal articles and conference papers available in the most relevant national and international databases. We analyze its productivity and time layout, according to the kind of document and language, as well as the scientific output by authors and departments, showing those most outstanding regarding productivity. On the other hand, we have researched the distribution and layout of scientific literature, pointing out the most used journals. The results show as the most relevant aspects a wide range of themes covered, the constant annual increase of scientific productivity, as well as a wide use of international journals with impact.Alonso Arroyo, Adolfo.

Identifying institutional relationships in a geographically distributed public health system using interlinking and co-authorship methods

The final publication is available at Springer via http://dx.doi.org/ 10.1007/s11192-016-1839-zLink analysis is highly effective in detecting relationships between different institutions, relationships that are stronger the greater their geographical proximity. We therefore decided to apply an interlinking analysis to a set of geographically dispersed research entities and to compare the results with the co-authorship patterns between these institutions in order to determine how, and if, these two techniques might reveal complementary insights. We set out to study the specific sector of public health in Spain, a country with a high degree of regional autonomy. We recorded all Spanish health entities (and their corresponding URLs) that belong to, and were hyperlinked from, the national government or any of the regional governments, gathering a total of 263 URLs. After considering their suitability for web metric analysis, interlinking scores between all valid URLs were obtained. In addition, the number of co-authored articles by each pair of institutions and the total scientific output per institution were retrieved from Scopus. Both interlinking and co-authorship methods detect the existence of strength subnets of geographically distributed nodes (especially the Catalan entities) as well as their high connectivity with the main national network nodes (subnet of nodes distributed according to dependence on national government, in this case Spain). However, the resulting interlinking pattern shows a low but significant correlation (r = 0.5) with scientific co-authorship patterns. The existence of institutions that are strongly interlinked but with limited scientific collaboration (and vice versa) reveals that links within this network are not accurately reflecting existing scientific collaborations, due to inconsistent web content development.Ontalba Ruipérez, JA.; Orduña Malea, E.; Alonso-Arroyo, A.

La relación entre las palabras clave aportadas por los autores de artículos de revista y su indización en las bases de datos ISOC, IME e ICYT

The keywords provided by authors in their scientific articles and the descriptors assigned to those articles in various databases are analysed to find out the role played by these keywords during the indexing process. In order to do that, 108 periodical publications proportionally distributed between Social Sciences and Humanities (36 journals), Science and Technology (36) and Medical and Health Sciences (36) were selected. Ten articles were selected from each of the 108 journals from different years, so that we worked altogether on 1080 articles meeting two conditions: including keywords and being indexed in the databases ISOC, ICYT or IME. Then, we proceeded to draw a comparison between the keywords used by the authors of the 1080 articles with the descriptors assigned by the database indexers. The comparison shows that in IME database 64.96% of the keywords provided by the authors exactly coincide with the descriptors or just do so after normalization; 60.48% in ISOC and 58.18% in ICYT.Se analizan las palabras clave proporcionadas por autores en sus artículos científicos y los descriptores asignados a dichos artículos en varias bases de datos para averiguar el papel que juegan esas palabras clave durante el proceso de indización de los mismos. Para ello, se seleccionaron 108 publicaciones periódicas repartidas proporcionalmente entre Ciencias Sociales y Humanidades (36 revistas), Ciencia y Tecnología (36) y Ciencias Médicas y de la Salud (36). De cada una de las 108 publicaciones se escogieron 10 artículos repartidos entre diferentes años, por lo que se trabajó con un total de 1080 que cumplían dos condiciones: poseer palabras clave y estar indizados en las bases de datos ISOC, ICYT o IME. Posteriormente, se procedió a contrastar las palabras clave de los autores de los 1080 artículos con los descriptores asignados por los indizadores en estas bases de datos. En la comparación se constata que, en la base de datos IME, el 64,96% de las palabras clave proporcionadas por los autores coincide con los descriptores exactamente o tras una normalización; en ISOC es el 60,48% y en ICYT el 58,18%

Analysis of scientific production in spanish implantology

The aim of the study was to quantify the scientific productivity of researchers, organizations, and regions in Spain that publish articles on implantology in dental journals indexed in Journal Citation Reports. A search was conducted among the core collection of Thomson Reuters? Web of Science database, on the basis of its broad thematic and geographic coverage of health sciences. The search identified original articles ? the main vehicle for the dissemination of research results. The search was conducted in July 2016, applying the truncated search term ?implant*? to locate original articles on implantology and its derivative forms. The search was conducted within the topic field (title, keywords and abstract) and two inclusion criteria were applied: documents denominated as articles were included; and articles categorized as Web of Science Medicine Dentistry and Oral Surgery. Finally only articles for which one of the participating organizations was located in Spain were selected. The final search identified a total of 774 records. The period 1988 to 2015 saw an exponential growth in scientific production, especially during the last 10 years. Clinical Oral Implants Research and Medicina Oral Patologia Oral y Cirugia Bucal (Oral Medicine, Oral Pathology, and Oral Surgery) were the most productive journals. Collaborative networks among authors and among institutions increased and this increase was related to the improving quality of the publications. Bibliometric analysis revealed a significant growth in the quantity and quality of Spanish implantology literature. Most key bibliometric indicators demonstrated upward trends
