Research paper thumbnail of Visualization of association graphs for assisting the interpretation of classifications

We adapt for this purpose the TermWatch system that comprises a term extractor, a relation identifier which yields the terminological network and a clustering module. The results are output on two interfaces: a graphic one mapping the clusters in a 2D space and a terminological hypertext network allowing the user to interactively explore results and return to source texts.

We propose a set of indicators about Web users, visualized bibliographic records, and e-commercial transactions. In addition, we introduce two Web usage factors.

The association analysis makes use of Web site links in order to produce a representation of sites association structure. A description of the association network is the goal to reach. The data refers to 791 university sites from the 15 countries belonging to the European

We propose advanced methods and algorithms based on bibliometric analysis applied on large-scale databases for scientific publications in order to identify emergent technologies. In the PROM-TECH project we demonstrated in a proof-of-concept approach the possible and reliable detection of growing research activity for a variety of technological fields. Building on this work, in ongoing investigations we analysed in-depth research progress for single technologies defined by classification categories of the PASCAL database.

Research paper thumbnail of An advanced diffusion model to identify emergent research issues: the case of optoelectronic devices

Scientometrics, 2010

Therefore our approach focuses on research activities of such technological elements on the basis of keywords in published articles. In this paper we show how emerging topics in the field of optoelectronic devices based on scientific literature data from the PASCAL-database can be identified. We use Results from PROM-TECH project, whose principal objective was to produce a methodology allowing the identification of promising emerging technologies. In this project, the study of the intersection of Applied Sciences as well as Life (Biological & Medical) Sciences domains and Physics with bibliometric methods produced 45 candidate technological fields and the validation by expert panels led to a final selection of 10 most promising ones. These 45 technologies were used as reference fields. In order to detect the emerging research, we combine two methodological approaches. The first one introduces a new modelling of field terminology evolution based on bibliometric indicators: the diffusion model and the second one is a diachronic cluster analysis. With the diffusion model we identified single keywords that represent a high dynamic of the mentioned technology elements. The cluster analysis was used to recombine articles, where the identified keywords were used to technological topics in the field of optoelectronic devices. This methodology allows us to answer the following questions: Which technological aspects within our considered field can be detected? Which of them are already established and which of them are new? How are the topics linked to each other?

We propose a battery of indicators about Web users, used bibliographic records and e-commercial transactions. In addition, we introduce two Web usage factors and we give an overview of the co-usage analysis. For these tasks, we present a computer-based system, called Miri@d, which produces descriptive statistical information about Web users' searching behaviour, and what is effectively used from a free-access digital bibliographical database.

Nous avons choisi de travailler à partir d'une base de données bibliographique et de nous appuyer sur son plan de classement pour analyser la dynamique des différents domaines thématiques de la base. Cette approche a été combinée à une analyse réalisée par des experts qui nous ont apporté leur vision prospective de leurs domaines de compétence. Dans cet article, nous présenterons les critères qui nous ont guidés pour le choix de la base de données, puis nous décrirons notre méthodologie qui alterne les approches bibliométriques basées sur la notion de plan de classement et les approches par experts pour sélectionner les thématiques prometteuses.

Nous conclurons par une discussion sur les problématiques associées à ce type de projet : comment caractériser la dynamique d'une thématique, voire des émergences ?
