Collaboration practices vary greatly per scientific area and discipline and influence the scientific performance and its scholarly communication. In this study, the collaborative pattern of the Information Retrieval (IR) research field is analyzed using co-authored articles retrieved from Social Science Citation Index for a period of 11 years from 1987 to 1997. The level of collaboration, journal collaborative distribution, disciplinary collaborative distribution and country collaboration are probed according to IR collaborative research. Findings are discussed from the above perspectives in detail. In particular, this study reveals a perceptible upward trend of collaborative IR research with the results of these research efforts being reported in all major core IR journals. The inter-disciplinary and intra-disciplinary scholarly communications in collaborative researches are very much in evidence and cover broad areas like psychology, and computer and medical sciences, respectively. 相似文献

Scientific collaboration is a significant behavior in knowledge creation and idea exchange. To tackle large and complex research questions, a trend of team formation has been observed in recent decades. In this study, we focus on recognizing collaborative teams and exploring inner patterns using scholarly big graph data. We propose a collaborative team recognition (CORE) model with a ”core + extension” team structure to recognize collaborative teams in large academic networks. In CORE, we combine an effective evaluation index called the collaboration intensity index with a series of structural features to recognize collaborative teams in which members are in close collaboration relationships. Then, CORE is used to guide the core team members to their extension members. CORE can also serve as the foundation for team-based research. The simulation results indicate that CORE reveals inner patterns of scientific collaboration: senior scholars have broad collaborative relationships and fixed collaboration patterns, which are the underlying mechanisms of team assembly. The experimental results demonstrate that CORE is promising compared with state-of-the-art methods. 相似文献

In information retrieval research, models and systems traditionally assume that a single person is querying and reviewing the results. However, several empirical studies of professional practice identified collaboration during IR as everyday work patterns in order to solve a shared information need and to benefit from the diverse expertise and experience of the team members. Moreover, most IR systems that are employed in professional work routines are designed for individual use and prototype collaborative systems are too limited to support use in todays work practice. To bridge this gap, this papers develops and formalizes a decision theoretic approach towards supporting a team of people that explicitly set out together to resolve a shared information need. We develop a formal cost model for collaborative IR that considers the trade-off between estimated relevance of a document as well as estimated document redundancy. From this cost model, we use a decision theoretic approach to derive the notion of activity suggestions, that is, a formal optimum criterion that describes optimum collaboration strategies in IR as the solution of an integer linear program. Those collaboration strategies are suggested to team members with the aim to facilitate the collaborative performance of information retrieval tasks. We demonstrate the application of our model by means of search result division in two collaborative search tasks. In the conducted experiments, we study the effects of different domain knowledge and resulting relevance assessments of team members in four different conditions. The gathered results indicate that our approach can improve the retrieval effectiveness of teams in recall-oriented tasks. 相似文献

International scientific collaboration has been the dominant driving force for promoting scientific and technological advancement. However, current international scientific collaboration analysis and evaluation mainly concentrate on the exploration of international collaboration network; hence, an evaluation method of international scientific collaboration is yet to be formed. In this paper, we take the dye-sensitized solar cells (DSSCs) as an empirical object and combine the international collaboration network with geographic information, which we call the International Collaboration Map, to display the international collaboration situations among countries or regions worldwide (inter-country collaboration), the collaborations among countries or regions within each continent (intra-continent collaboration), and the collaborations among continents (inter-continent collaboration) from different angles. Based on the thought of fractional count, this study introduces the indicators of collaborative country rank, international collaboration width, and international collaboration activity; the study employs the International Collaboration Activity Index (ICAI) to comprehensively measure the degree of countries or regions international collaboration at the country or region level. It systematically evaluates the differences between the active degree of relevant countries or regions in collaborative research. We use correlation analysis among the five sub-criterions and verify the rationality of index construction. K-means clustering analysis is undertaken among 84 countries or regions in the DSSCs field. The results show the formation of three groups, each with their unique international collaboration features. 相似文献

It is widely believed that collaboration is advantageous in science, for example, with collaboratively written articles tending to attract more citations than solo articles and strong arguments for the value of interdisciplinary collaboration. Nevertheless, it is not known whether the same is true for research that produces books. This article tests whether co-authored scholarly monographs attract more citations than solo monographs using books published before 2011 from 30 categories in the Web of Science. The results show that solo monographs numerically dominate collaborative monographs, but give no evidence of a citation advantage for collaboration on monographs. In contrast, for nearly all these subjects (28 out of 30) there was a citation advantage for collaboratively produced journal articles. As a result, research managers and funders should not incentivise collaborative research in book-based subjects or in research that aims to produce monographs, but should allow the researchers themselves to freely decide whether to collaborate or not. 相似文献

Academic libraries are increasingly called upon to demonstrate their value to their home institutions. Research collaboration with faculty resulting in the co-authorship of scholarly output is one possible way to demonstrate the alignment of the library with the institutional mission. Involvement in research also improves librarians' skills in offering research support services. This study explores the contribution of librarians to scholarly journals in fields other than Library and Information Science (LIS) as well as their collaboration practices with researchers in those fields. Results show an increasing number of papers published by library-affiliated authors in non-LIS journals between 2006 and 2015. The papers fall broadly into four areas: articles on topics related to LIS published in non-LIS journals; higher education and information literacy; systematic reviews and meta-analysis; and research collaboration in the faculty's areas of expertise. The study is limited by the difficulty in properly retrieving the scholarly output of librarians from bibliographic databases and the difficulty in ascertaining their contributions to published articles. 相似文献

This article reports a comparative study of five measures that quantify the degree of research collaboration, including the collaborative index, the degree of collaboration, the collaborative coefficient, the revised collaborative coefficient, and degree centrality. The empirical results showed that these measures all capture the notion of research collaboration, which is consistent with prior studies. Moreover, the results showed that degree centrality, the revised collaborative coefficient, and the degree of collaboration had the highest coefficient estimates on research productivity, the average JIF, and the average number of citations, respectively. Overall, this article suggests that the degree of collaboration and the revised collaborative coefficient are superior measures that can be applied to bibliometric studies for future researchers. 相似文献

This paper proposes a new node centrality measurement index (c-index) and its derivative indexes (iterative c-index and cg-index) to measure the collaboration competence of a node in a weighted network. We prove that c-index observe the power law distribution in the weighted scale-free network. A case study of a very large scientific collaboration network indicates that the indexes proposed in this paper are different from other common centrality measures (degree centrality, betweenness centrality, closeness centrality, eigenvector centrality and node strength) and other h-type indexes (lobby-index, w-lobby index and h-degree). The c-index and its derivative indexes proposed in this paper comprehensively utilize the amount of nodes’ neighbors, link strengths and centrality information of neighbor nodes to measure the centrality of a node, composing a new unique centrality measure for collaborative competency. 相似文献

The debate on the role of women in the academic world has focused on various phenomena that could be at the root of the gender gap seen in many nations. However, in spite of the ever more collaborative character of scientific research, the issue of gender aspects in research collaborations has been treated in a marginal manner. In this article we apply an innovative bibliometric approach based on the propensity for collaboration by individual academics, which permits measurement of gender differences in the propensity to collaborate by fields, disciplines and forms of collaboration: intramural, extramural domestic and international. The analysis of the scientific production of Italian academics shows that women researchers register a greater capacity to collaborate in all the forms analyzed, with the exception of international collaboration, where there is still a gap in comparison to male colleagues. 相似文献

This paper explores the role of questioning in scientific meaning‐making as families talk, look and gesture in front of realistic and artful dioramas at the Natural History Museum of Los Angeles County. The focus is on the ways questioning can either enable movement towards scientific understanding or hinder such progress. The socio‐cultural framework of this research emphasizes Vygotsky's interpretation of the zone of proximal development (zpd). Questions are viewed as tools for mediation in the zpd. This paper examines three families' dialogues, excerpted from a larger study of collaborative sense‐making among family groups in a natural history museum. It seeks to understand how collaborative dialogue meshes everyday understandings with canonical science, in this case through the use of questions. 相似文献

Palestine is a small newly established state in the Middle East. The objective of this study was to assess the quantity and quality of research output from Palestine after Oslo peace accords. The data used for this study were retrieved from Scopus database (officially known as Sciverse Scopus). Bibliometric analysis was used to identify the pattern of publication, relative growth rate, authorship pattern, collaborative measures, author's productivity, most prolific authors, and most prolific journals. A total of 3,585 published documents were retrieved from Palestine. A steady increase was observed after 2001. The h-index of the retrieved documents was 57. Fifty-three (1.48%) documents were published in Eastern Mediterranean Health Journal, whereas 52 (1.45%) and 49 (1.37%) documents were published in Journal of Dispersion Science and Technology and Asian Journal of Chemistry, respectively. Half of the top 20 journals in which Palestinian researchers had published their articles were un-indexed in Institute for Scientific Information (ISI) web of knowledge. The highest number of documents published by a Palestinian researcher was 79. The main subject area of published documents from Palestine was medicine (717; 20.00%), followed by chemistry (551, 15.37%), and engineering (530, 14.78%). The top countries involved in research collaboration with Palestine were the United States (422, 11.70%), followed by Germany (381; 10.71%), and the United Kingdom (208; 5.83%). There was a significant correlation between number of collaborating countries with Palestine in one hand, and quantity and quality of research activity in Palestine on the other hand. The number of collaborating countries with Palestine increased almost ten-fold from 1995 to 2012. Research output from Palestine showed steady growth since the Oslo peace accords. Research output was high from certain scientific disciplines while was lagging from others. Future emphasis on joint research, international collaboration, and publishing in indexed journals is needed. 相似文献

After two-years of repeat interviewing early career sciences/social sciences researchers from around the world about their work life and scholarly communications in pandemic-times, the Harbingers-2 project is in a position to release quantitative data on the pandemic's overall impact. The data comes from around 50 questions asked in the third and final round of interviews with 147 early career researchers (ECRs), which had a codifiable element to them (such as yes, no, do not know). The 19 scholarly topics covered include: pandemic-related research; research funding; changes to the workplace/working from home; pandemic-incurred stress and anxiety; teaching; employment security; career progression; mentoring; assessment (including metrics); collaboration; searching/finding information; ethics; networking; informal communication; publishing; sharing; pre-prints; outreach; and scholarly transformations. The main findings are that in six broad aspects of ECRs' work-life and scholarly behaviour, more than 50% of ECRs were impacted by the pandemic, with remote teaching having the greatest impact. By way of comparison, in another six aspects there was little change, least of all when it came to sharing activities. Among the countries studied, Malaysia stood out as being the most impacted, and of the disciplines it was the medical sciences and the soft social sciences most impacted. 相似文献

Scientific collaboration commonly takes place in a global and competitive environment. Coalitions and consortia are formed among universities, companies and research institutes to apply for research grants and to perform joint projects. In such a competitive environment, individual institutes may be strategic partners or competitors. Measures to determine partner importance have practical applications such as comparison and rating of competitors, reputation evaluation or performance evaluation of companies and institutes. Many network-centric metrics exist to measure the important of individuals or companies in social and collaborative networks. Here we present a novel context-based metric to measure the importance of partners in scientific collaboration networks. Well-established graph models such as the notion of hubs and authorities provide the basis for this work and are systematically extended to a flexible, context-aware network importance measure. 相似文献

This study explores the impact of different collaboration modes on the cited frequency of publications. Though several studies have obtained some research results, most of them exploit association or regression-based methods, which may not lead to causal conclusions. To overcome the above challenges, we use the Propensity Score Matching (PSM) method to analyze and compare the citation frequencies resulting from four groups of collaboration models: international versus domestic, international multilateral versus international bilateral, domestic inter-organizational versus domestic intra-organizational, and domestic multi-author versus domestic single-author. More specifically, we conduct this analysis by exploring the publications with three computer science subfields from the Web of Science (WoS) database. The experimental results show that international collaboration, especially international multilateral collaboration, has a significant role in increasing the frequency of citations to scientific publications, showing that internationalization and collaboration are critical factors in the growth of the impact of the papers. Among national co-publications, collaborative publications within national organizations receive a higher citation impact. Multi-author collaborations significantly increase citation frequency compared to single-author publications. Our heterogeneity analysis across the different subfields of the computer science domain finds that the treatment effects for the three subfields differ modestly and mostly significant from the whole sample. Moreover, besides the implications for developing research policy and scientist collaboration, our study can capture the causal effect between author collaboration patterns and citation frequency to reveal their causal effects. 相似文献
