    This is an accepted manuscript of an article published by Wiley Blackwell in Journal of the Association for Information Science and Technology on 17/07/2017, available online: https://doi.org/10.1002/asi.23821 The accepted version of the publication may differ from the final published version.Patents sometimes cite web pages either as general background to the problem being addressed or to identify prior publications that will limit the scope of the patent granted. Counts of the number of patents citing an organisation’s website may therefore provide an indicator of its technological capacity or relevance. This article introduces methods to extract URL citations from patents and evaluates the usefulness of counts of patent web citations as a technology indicator. An analysis of patents citing 200 US universities or 177 UK universities found computer science and engineering departments to be frequently cited, as well as research-related web pages, such as Wikipedia, YouTube or Internet Archive. Overall, however, patent URL citations seem to be frequent enough to be useful for ranking major US and the top few UK universities if popular hosted subdomains are filtered out, but the hit count estimates on the first search engine results page should not be relied upon for accuracy

    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.

    Redes de conectividad entre empresas tecnológicas a través de un análisis métrico longitudinal de menciones de usuario en Twitter

    Get PDF
    El objetivo principal de este trabajo es identificar y describir (mediante un análisis cibermétrico de menciones de usuario) la intensidad y evolución de las relaciones establecidas entre compañías de un determinado sector industrial (tecnología) a través de sus correspondientes cuentas corporativas de Twitter, con el propósito de comprobar el valor que un análisis métrico de estas características puede tener a la hora de determinar la conectividad entre dichas compañías. Para ello se han contabilizado las menciones, tanto directas (MT) como ReTweets (RT), entre las cuentas de Twitter de una muestra de 50 compañías internacionales durante un período de seis meses. Los resultados indican que el grado de interacción entre las 50 empresas tecnológicas es débil (tanto si contamos el número de conexiones establecidas como si cuantificamos la intensidad de estas conexiones), estable, concentrado en unas pocas relaciones específicas y de carácter marcadamente asimétrico. Se concluye que, dada la baja interactividad detectada, las cuentas corporativas de las empresas tecnológicas en Twitter no son suficientes para analizar desde un punto de vista métrico la conectividad web establecida entre éstas, aunque sí útiles para conocer las políticas de comunicación oficiales entre ellas.This work has been carried out in the framework of the research project with reference APOSTD/2013/002, funded by the Regional Ministry of Education, Culture and Sport (Generalitat Valenciana, Spain).Azorín-Richarte, D.; Orduña Malea, E.; Ontalba Ruipérez, JA.

    Visualising the intellectual and social structures of digital humanities using an invisible college model

    Get PDF
    This thesis explores the intellectual and social structures of an emerging field, Digital Humanities (DH). After around 70 years of development, DH claims to differentiate itself from the traditional Humanities for its inclusiveness, diversity, and collaboration. However, the ‘big tent’ concept not only limits our understandings of its research structure, but also results in a lack of empirical review and sustainable support. Under this umbrella, whether there are merely fragmented topics, or a consolidated knowledge system is still unknown. This study seeks to answer three research questions: a) Subject: What research topics is the DH subject composed of? b) Scholar: Who has contributed to the development of DH? c) Environment: How diverse are the backgrounds of DH scholars? The Invisible College research model is refined and applied as the methodological framework that produces four visualised networks. As the results show, DH currently contributes more towards the general historical literacy and information science, while longitudinally, it was heavily involved in computational linguistics. Humanistic topics are more popular and central, while technical topics are relatively peripheral and have stronger connections with non-Anglophone communities. DH social networks are at the early stages of development, and the formation is heavily influenced by non-academic and non-intellectual factors, e.g., language, working country, and informal relationships. Although male scholars have dominated the field, female scholars have encouraged more communication and built more collaborations. Despite the growing appeals for more diversity, the level of international collaboration in DH is more extensive than in many other disciplines. These findings can help us gain new understandings on the central and critical questions about DH. To the best of the candidate’s knowledge, this study is the first to investigate the formal and informal structures in DH with a well-grounded research model

    Pla de màrqueting i visibilitat digital de la revista BID

    Màster en Gestió de Continguts Digitals, Facultat de Biblioteconomia i Documentació, Universitat de Barcelona i UPF, curs 2014-2015. Tutor: Dr. Mario Pérez-Montoro (UB)Amb la generalització de l’ús d’Internet per a la investigació científica (edició electrònica, cercadors, agregadors, bases de dades), el màrqueting digital esdevé una tècnica essencial per augmentar la visibilitat i el creixement de les revistes digitals. La producció científica ha augmentat exponencialment en les darreres dècades, de forma que els investigadors, saturats d’informació, han de ser selectius a l’hora de llegir noves publicacions i cada vegada tenen més dificultats per detectar quines són més rellevants o transcendents. A aquest fet es suma que ja no s’accedeix directament a la producció científica, sinó que els rastrejadors dels diferents motors de cerca fan d’intermediaris indexant els resultats de la recerca de forma automatitzada. En aquest context, la tasca dels editors va més enllà de publicar continguts de qualitat per als seus lectors, ara també han de publicar continguts optimitzats per a aquests rastrejadors. El SEO (Search Engine Optimization), la presència en xarxes socials i l’optimització de les webs que allotgen aquesta producció científica esdevenen tècniques imprescindibles per arribar als lectors interessats en els continguts que es publiquen. Els articles de la revista BiD: Textos universitaris de biblioteconomia i documentació es troben difosos en aquesta quantitat ingent d’informació i, des de l’equip editorial es planteja la necessitat d’emprendre mesures per a ubicar la revista a la web i fer-la visible per a aquells usuaris que puguin trobar els seus continguts interessants. Objectius Davant el repte d’esdevenir visible en un entorn com el que hem presentat, aquest treball planteja un pla de màrqueting i visibilitat digital que permeti a la revista BiD augmentar la seva visibilitat tan a nivell nacional com internacional, augmentar l’abast dels seus articles i fidelitzar els seus lectors. Amb totes aquestes actuacions, es pretén de forma indirecta augmentar l’impacte tan de la revista com dels articles que conté en la comunitat científica. Propostes finals Tenint en compte que l’objectiu últim d’aquest treball és que BiD adquireixi més rellevància entre la comunitat científica, hem fet una recerca exhaustiva dels sistemes de mesura d’aquesta rellevància. Per això les propostes de millora no només van lligades a l’augment de cites, sinó a l’augment del tràfic a la revista i ús dels seus articles i a les altmètriques que mesuren el nombre de mencions en marcadors socials, xarxes socials científiques i generals. Es proposen actuacions relacionades directament amb la millora del posicionament de BiD com són la unificació de dominis existents, la optimització del rendiment de la web, la descripció de les imatges amb textos alternatius i la definició d’un sistema de URLs amigables. A més, es plantegen actuacions per millorar la interrelació amb bases de dades científiques i cercadors acadèmics, per augmentar la visibilitat de la revista en l’entorn científic. Aquestes millores van vinculades a la implementació d’un sistema de metaetiquetes optimitzades per a aquests entorns i a la creació d’un perfil específic de la revista a Google Scholar Citations. Una altra estratègia per augmentar la visibilitat a la comunitat científica és establir un sistema d’intercanvi de bàners amb revistes i entitats relacionades a BiD per configurar una xarxa d’enllaços de qualitat que remetin tràfic a la revista. Per obtenir la interacció dels lectors i poder conèixer les seves necessitats amb més profunditat es planteja també un pla de xarxes socials genèriques i especialitzades per a científics.

Given the limitations on searching Twitter’s public application programming interface (API), we used the Topsy search engine as a source for compiling tweets. To this end, we took a global sample of 200 universities and compiled all the tweets with hyperlinks to any of these institutions. Further link data was obtained from alternative sources (MajesticSEO and OpenSiteExplorer) in order to compare the results. Thereafter, various statistical tests were performed to determine the correlation between the indicators and the possibility of predicting external links from the collected tweets. The results indicate a high volume of tweets, although they are skewed by the performance of specific universities and countries. The data provided by Topsy correlated significantly with all link indicators, particularly with OpenSiteExplorer (r = 0.769). Finally, prediction models do not provide optimum results because of high error rates. We conclude that the use of Twitter (via Topsy) as a source of hyperlinks to universities produces promising results due to its high correlation with link indicators, though limited by policies and culture regarding use and presence in social networks.Orduña Malea, E.; Torres-Salinas, D.; Delgado López-Cózar, E.
