Evaluation of Inciso: A system for automatic elaboration of a Citation Index in Social Science Spanish Journal
2007
We have developed a system that can elaborate a citation index in an automated way. It has been tested with Spanish journals. We need evaluate our system, mainly in effectiveness of the retrieval of citations. Criteria for evaluation of the system is presented and discussed, and the results of the application to our system are showed and analyzed.
Export Price Discrimination in Europe and Exchange Rates
2002
The paper studies pricing-to-market behavior on a wide range of disaggregated European Union exports to OECD countries. The sample allows better identification of products for which such behavior is pervasive. The results suggest that the degree of markup adjustment in response to exchange rate changes is similar across destination markets. The evidence of pricing-to-market across source countries ranges from 40% (Netherlands) to 63% (Germany) of the products in the sample, except for the United Kingdom, where there is remarkably little evidence of it. However, formal comparisons across source countries by product do not usually reveal differences in behavior.
Radiative heat exchanges of people in complex geometry buildings: An experimentally based algorithm for computing angle factors
2008
Thermal comfort of people working or living in confined spaces depends, to a large extent, on the radiative thermal exchanges. These contributions are expressed, among other things, as a function of the mean radiant temperature that, in the general cases where there is a presence of high intensity sources, must be expressed as a function of the angle factors between subjects and the surrounding surfaces of enclosures. Angle factors, in turn, depend on the projected area factors. Despite this evidence, at the present there is a lack in the availability of simple and reliable methods capable of computing angle factors of people in assigned postures with respect to complex geometry buildings. …
Corporate Social Responsibility and Sustainability of Local Community: A Case Study of the Transnational Project in China-Pakistan Economic Corridor
2019
While achieving great benefits, the Belt and Road Initiative (BRI) has triggered potential problems between the transnational projects and local communities in the participant countries. However, there is still a knowledge gap on how corporate social responsibility (CSR) is adopted, and how CSR affects the local community. Based on a context of China-Pakistan Economic Corridor (CPEC), this research exploits a combination of qualitative and quantitative methods to fill the gap. It finds that the CSR activities in the CPEC project are initiated by the long-term CSR initiative. Organized by the professional CSR foundation in an autonomous environment, the panoramic CSR activities are governed …
Notice of Violation of IEEE Publication Principles: Distributed Multimedia Digital Libraries on Peer-to-Peer Networks
2007
This paper presents an original approach to image sharing in large, distributed digital libraries, in which a user is able to interactively search interesting resources by means of content-based image retrieval techniques. The approach described here addresses the issues arising when the content is managed through a peer-to-peer architecture. In this case, the retrieval facilities are likely to be limited to queries based on unique identifiers or small sets of keywords, which may be quite inadequate, so we propose a novel algorithm for routing user queries that exploits compact representations of multimedia resources shared by each peer in order to dynamically adapt the network topology to …
Genre-adaptive Semantic Computing and Audio-based Modelling for Music Mood Annotation
2016
This study investigates whether taking genre into account is beneficial for automatic music mood annotation in terms of core affects valence, arousal, and tension, as well as several other mood scales. Novel techniques employing genre-adaptive semantic computing and audio-based modelling are proposed. A technique called the ACTwg employs genre-adaptive semantic computing of mood-related social tags, whereas ACTwg-SLPwg combines semantic computing and audio-based modelling, both in a genre-adaptive manner. The proposed techniques are experimentally evaluated at predicting listener ratings related to a set of 600 popular music tracks spanning multiple genres. The results show that ACTwg outpe…
WORDY: a Semi-automatic Methodology aimed at the Creation of Neologisms based on a Semantic Network and Blending Devices
2017
In this paper, we propose a semi-automatic tool, named WORDY, that implements a methodology aimed at speeding-up the pro- cess of creation of neologisms. The approach exploits a semantic network, which is explored through the spreading activation methodology and ex- ploits three blending linguistic techniques together with a proper ranking function in order to support companies in the creation of neologisms ca- pable of evoking semantic meaningful associations to customers.
Entity Recommendation for Everyday Digital Tasks
2021
| openaire: EC/H2020/826266/EU//CO-ADAPT Recommender systems can support everyday digital tasks by retrieving and recommending useful information contextually. This is becoming increasingly relevant in services and operating systems. Previous research often focuses on specific recommendation tasks with data captured from interactions with an individual application. The quality of recommendations is also often evaluated addressing only computational measures of accuracy, without investigating the usefulness of recommendations in realistic tasks. The aim of this work is to synthesize the research in this area through a novel approach by (1) demonstrating comprehensive digital activity monitor…
Automatic image representation for content-based access to personal photo album
2007
The proposed work exploits methods and techniques for automatic characterization of images for content-based access to personal photo libraries. Several techniques, even if not reliable enough to address the general problem of content-based image retrieval, have been proven quite robust in a limited domain such as the one of personal photo album. In particular, starting from the observation that most personal photos depict a usually small number of people in a relatively small number of different contexts (e.g. Beach, Public Garden, Indoor, Nature, Snow, City, etc...) we propose the use of automatic techniques borrowed from the fields of computer vision and pattern recognition to index imag…
La sécurisation des parcours des apprentis à l'épreuve du temps et du choix politique

En ligne sur : http://www.cereq.fr/index.php/content/download/7936/71610/file/Relief42.pdf; National audience; Autant de questions auxquelles cette communication apportera des éléments de réponse. Celle-ci se déclinera en trois étapes, présentée en trois sections. La première sera une connaissance du contexte, des contraintes de l'expérimentation, et de l'implication des acteurs. Le deuxième temps apportera un éclairage sur les jeunes apprentis et les impacts du tutorat après deux années d'observation. Enfin, l'objet de la troisième section sera de mettre en exergue les propositions quant aux pratiques transférables du dispositif et la décision finale prise par le conseil régional. Le carac…
