1He, C. ; Wu, J. ; Zhang, Q.: Proximity-aware research leadership recommendation in research collaboration via deep neural networks.
In: Journal of the Association for Information Science and Technology. 73(2022) no.1, S.70-89.
Abstract: Collaborator recommendation is of great significance for facilitating research collaboration. Proximities have been demonstrated to be significant factors and determinants of research collaboration. Research leadership is associated with not only the capability to integrate resources to launch and sustain the research project but also the production and academic impact of the collaboration team. However, existing studies mainly focus on social or cognitive proximity, failing to integrate critical proximities comprehensively. Besides, existing studies focus on recommending relationships among all the coauthors, ignoring leadership in research collaboration. In this article, we propose a proximity-aware research leadership recommendation (PRLR) model to systematically integrate critical node attribute information (critical proximities) and network features to conduct research leadership recommendation by predicting the directed links in the research leadership network. PRLR integrates cognitive, geographical, and institutional proximity as node attribute information and constructs a leadership-aware coauthorship network to preserve the research leadership information. PRLR learns the node attribute information, the local network features, and the global network features with an autoencoder model, a joint probability constraint, and an attribute-aware skip-gram model, respectively. Extensive experiments and ablation studies have been conducted, demonstrating that PRLR significantly outperforms the state-of-the-art collaborator recommendation models in research leadership recommendation.

2He, C. ; Wu, J. ; Zhang, Q.: Research leadership flow determinants and the role of proximity in research collaborations.
In: Journal of the Association for Information Science and Technology. 71(2020) no.11, S.1341-1356.
Abstract: Characterizing the leadership in research is important to revealing the interaction pattern and organizational structure through research collaboration. This research defines the leadership role based on the corresponding author's affiliation, and presents the first quantitative research on the factors and evolution of 5 proximity dimensions (geographical, cognitive, institutional, social, and economic) of research leadership. The data to capture research leadership consist of a set of multi-institution articles in the fields of "Life Sciences & Biomedicine," "Technology," "Physical Sciences," "Social Sciences," and "Humanities & Arts" during 2013-2017 from the Web of Science Core Citation Database. A Tobit regression-based gravity model indicates that the mass of research leadership of both the leading and participating institutions and the geographical, cognitive, institutional, social, and economic proximities are important factors for the flow of research leadership among Chinese institutions. In general, the effect of these proximities for research leadership flow has been declining recently. The outcome of this research sheds light on the leadership evolution and flow among Chinese institutions, and thus can provide evidence and support for grant allocation policies to facilitate scientific research and collaborations.
4Wuthe, C.: CD-ROM-Datenbanken im Auskunftsdienst Öfentlicher Musikbibliotheken.
In: Forum Musikbibliothek. 1998, H.3, S.228-236.
Abstract: More data standardization is needed. If funds are limited, librarians should limit acquisitions at first to basic material. Each music librarian must balance potential use against avaiable resources and resulting costs. Contact with CD-ROM is facilitated by studying handbook instructions, bibliographies and general introductoins. Some important biliographic aids are described

5Lacroix, S. ; Marty, J.-C. ; Roche, C.: OK: a model of ontologies by differentiation.
In: Structures and relations in knowledge organization: Proceedings of the 5th International ISKO-Conference, Lille, 25.-29.8.1998. Ed.: W. Mustafa el Hadi et al. Würzburg : Ergon, 1998. S.336-342.
(Advances in knowledge organization; vol.6)
Abstract: This paper introduces a new model for the representation of ontologies. We expose our own definition of the term ontology, and we define the concepts, objects, attributes and classes manipulated. Then, we introduce the notion of "specific difference", which is central in our work. Each concept owns a specific difference, which is an attribute belonging to it, and which constitutes its main characteristic. While representing a particular ontology, it allows to specify which characteristic is the most representative of a concept, in order to differentiate it from its siblings and to specialise it from its parent. An ontology by differentiation (using the specific difference) is therefore constituted by a hierarchy of concepts, each concept being defined from a more abstract one by the addition of a specific difference. The construction of such an ontology also implies the use of a methodology for the acquisition of knowledge. This aspect of our work is therefore developed in this paper. The methodology is defined as a combination of diverse existing techniques, which we adapt to the acquisition of ontologies by differentiation
6Belayche, C.: ¬A propos de la classification de Dewey.
In: Bulletin d'informations de l'Association des Bibliothecaires Francais. 1997, no.175, S.22-23.
Abstract: All classifications are based on ideologies and Dewey is marked by its author's origins in 19th century North America. Subsequent revisions indicate changed ways of understanding the world. Section 157 (psycho-pathology) is now included with 616.89 (mental troubles), reflecting the move to a genetic-based approach. Table 5 (racial, ethnic and national groups) is however unchanged, despite changing views on such categorisation
