In this paper, we focus on the problem of automatically generating amplified scientific paper’s abstract which represents the most influential aspects of scientific paper. The influential aspects can be illustrated by the target scientific paper’s abstract and citation sentences discussing the target paper, which are provided in papers citing the target paper. In this paper, we extract representative sentences through data-weighted reconstruction approach(DWR) by jointly leveraging target scientific paper’s abstract and citation sentences’ content and structure. In our study, we make two-folded contributions.Firstly, sentence’s weight was learned by exploiting regularization for ranking on heterogeneous bibliographic network. Specially, Sentences-similar-Sentences relationship was identified by language modeling-based approach and added to the bibliographic network. Secondly, a data-weighted reconstruction objective function is optimized to select the most representative sentences which reconstructs the original sentence set with minimum error. In this process, sentences’ weight plays a critical role. Experimental evaluation over real dataset confirms the effectiveness of our approach. 相似文献

Citation analysis does not tell the whole story about the innovativeness of scientific papers. Works by prominent authors tend to receive disproportionately many citations, while publications by less well-known researchers covering the same topics may not attract as much attention. In this paper we address the shortcomings of traditional scientometric approaches by proposing a novel method that utilizes a classifier for predicting publication years based on latent topic distributions. We then calculate real-number innovation scores used to identify potential breakthrough papers and turnaround years. The proposed approach can complement existing citation-based measures of article importance and author contribution analysis; it opens as well novel research direction for time-based, innovation-centered research scientific output evaluation. In our experiments, we focus on two corpora of research papers published over several decades at two well-established conferences: The World Wide Web Conference (WWW) and the International ACM SIGIR Conference on Research and Development in Information Retrieval (SIGIR), containing around 3500 documents in total. We indicate significant years and demonstrate examples of highly-ranked papers, thus providing a novel insight on the evolution of the two conferences. Finally, we compare our results to citation analysis and discuss how our approach may complement traditional scientometrics. 相似文献

Research evaluation, which is an increasingly pressing issue, invariably relies on citation counts. In this contribution we highlight two concerns that the research community needs to pay attention to. One, in the world of search engine facilitated research, factors such as ease of Web discovery, ease of access, and content relevance, rather than quality, influence what gets read and cited. Two, research evaluation based on citation counts works against many types of high-quality works. We also elaborate on the implications of these points by examining a recent nationwide evaluation of researchers performed in Italy. We focus on our discipline (computer science), but we believe that our observations have relevance for a broad audience. 相似文献

引用认同分析：引文分析的新视角 总被引：1，自引：0，他引：1
作者的引用认同是该作者所引用过的所有作者的集合。与传统的引文分析方法不同,引用认同分析以作者（引用者和被引者）为研究对象。本文选取图书情报界3位著名学者作为研究对象,进行实证研究,探讨引用认同的分布规律以及作者的引用风格。Abstract： An author＇s citation identity is a set of authors that he cites. Different from traditional citation analysis,citation identity analysis takes authors （ citers and citees） as the object of study. This paper selects 3 well-known scholars in library and information science circles as the object of study to conduct an empirical analysis with special focus on the distribution law of citation identity and the authors＇ citing styles. 相似文献

Previous studies have confirmed that citation mention and location reveal different contributions of the cited articles, and that both are significant in scientific research evaluation. However, traditional citation count prediction only focuses on predicting citation frequency. In this paper, we propose a novel fine-grained citation count prediction task (FGCCP), which aims to predict in-text citation count from each structural function of a paper separately. Specifically, we treated this task as a “sequence to sequence” issue and a multi-task learning job, in which both the inputs and the outputs are based on the sequence pattern of citations from different structural functions. To fulfill FGCCP, we proposed a transformer-based model (i.e. MTAT) in which a novel among-attention mechanism is employed. Based on an empirical study of full-text documents from PubMed Central Open Access Subset, our model achieves satisfactory prediction accuracy, and surpasses common machine learning and deep learning models on FGCCP. Moreover, we also discuss the potential role of the among-attention mechanism and the reason why our proposed model outperforms state-of-the-art strategies. FGCCP may provide more detailed decision-making evidence and evaluation basis for researchers in scientific research evaluation. In addition, MTAT is a general model which can be easily deployed in other multi-task learning jobs. 相似文献

Mining linkage information from the citation graph has been shown to be effective in identifying important literatures. However, the question of how to utilize linkage information from the citation graph to facilitate literature retrieval still remains largely unanswered. In this paper, given the context of biomedical literature retrieval, we first conduct a case study in order to find out whether applying PageRank and HITS algorithms directly to the citation graph is the best way of utilizing citation linkage information for improving biomedical literature retrieval. Second, we propose a probabilistic combination framework for integrating citation information into the content-based information retrieval weighting model. Based on the observations of the case study, we present two strategies for modeling the linkage information contained in the citation graph. The proposed framework provides a theoretical support for the combination of content and linkage information. Under this framework, exhaustive parameter tuning can be avoided. Extensive experiments on three TREC Genomics collections demonstrate the advantages and effectiveness of our proposed methods. 相似文献

Quantitative research evaluation requires measures that are transparent, relatively simple, and free of disciplinary and temporal bias. We document and provide a solution to a hitherto unaddressed temporal bias – citation inflation – which arises from the basic fact that scientific publication is steadily growing at roughly 4% per year. Moreover, because the total production of citations grows by a factor of 2 every 12 years, this means that the real value of a citation depends on when it was produced. Consequently, failing to convert nominal citation values into real citation values produces significant mis-measurement of scientific impact. To address this problem, we develop a citation deflator method, outline the steps to generalize and implement it using the Web of Science portal, and analyze a large set of researchers from biology and physics to demonstrate how two common evaluation metrics – total citations and h-index – can differ by a remarkable amount depending on whether the underlying citation counts are deflated or not. In particular, our results show that the scientific impact of prior generations is likely to be significantly underestimated when citations are not deflated, often by 100% or more of the nominal value. Thus, our study points to the need for a systemic overhaul of the counting methods used evaluating citation impact – especially in the case of researchers, journals, and institutions – which can span several decades and thus several doubling periods. 相似文献

This paper looks at how citations are perceived among scientists. Based on a questionnaire survey it traces the repertoire of views and experiences about citations that could be found among Norwegian scientists that had published highly cited papers. Their views circle around three issues: the relation between the quality (or importance or significance) of a paper and its citation history; the importance of visibility and how different sorts of factors play a role in determining citation in general and high citation in particular; and the fairness (or lack of fairness) of the system. Taken together, the respondents’ answers and comments offer an informal (and fragmented) sociology of citations and their role in the world of science. In the final section we discuss the relevance of our findings in respect to the increasing use of citation indicators in science policy and research evaluations. 相似文献

The Web is revolutionizing the entire scholarly communication process and changing the way that researchers exchange information. In this paper, we analyze two views of information production and use in computer-related research based on citation analysis of PDF and Postcript formatted publications on the Web using autonomous citation indexing (ACI), and a parallel citation analysis of the journal literature indexed by the Institute for Scientific Information (ISI) in SCISEARCH. Our goal is to establish a baseline profile of computer science “literature” as it appears in the published journals and as it appears on the publicly available Web. From this starting point, we hope to identify additional research areas dealing with information dissemination and citation practices in computer science and the utility of autonomous citation indexing on the Web as an adjunct to commercial indexing 相似文献

Research evaluating models of scientific productivity require coherent metrics that quantify various key relations among papers as revealed by patterns of citation. This paper focuses on the various conceptual problems inherent in measuring the degree to which papers tend to cite other papers written by authors of the same nationality. We suggest that measures can be given a degree of assurance of coherence by being based on mathematical models describing the citation process. A number of such models are developed. 相似文献

Numbers of publications and citation ratings have recently been used as measures of scientific growth. The present paper discusses a number of presumed weaknesses of these measures. First, a distinction is made among scientific activity, scientific productivity, and scientific progress. Then it is suggested that the above measures might depend on the particular field of science, on the speed whereby research front information becomes archival, on the phenomena of wrong papers and of ‘also ran’ papers, on the geographical differences in communication patterns, on whether we want to measure activity, productivity, or progress, and on the temporal variations in scientific communication patterns. Though some examples are given, the quantitative substantiation of the proposed effects must await further research. 相似文献

We present a study exploring the connection between social networks and collaborative process. We focus on exploring academics' network position and its effect on their collaborative networks. In this paper, we discuss two types of networks of collaboration—(i) citation; and, (ii) co authorship. We explore the effects of social networks on these two types of collaborative process. By defining network position in this way, we develop a social network that uses the academics as nodes within the network instead of each published paper. We obtained the collaboration data through archival records (i.e. Web of Science) and examined the interactions among different actors from the archival records for determining the existence and strength of relations between actors. 相似文献
