带有数据链接的文章和没有数据链接的文章之间的引用率是否存在差异？除了从纯学术的角度来看是有趣的，这个问题也是高度相关的推进科学的过程。数据共享不仅有助于索赔的核实过程，而且有助于在档案数据中发现新的发现。然而，链接到数据仍然远远没有成为一种“实践”，特别是当作者在写作和提交过程中提供这些链接时。你需要有一个意愿和一个出版机制，以创造这样的做法。显示与数据链接的文章获得更高的引用率可能会增加科学家采取额外步骤将数据源链接到他们的出版物的意愿。在这个演示中，我们将展示这确实是这样的情况：与数据链接的文章比没有这样的链接的文章有更高的引用率。ADS由NASA Grant NNX 09 AB 39 G资助。
英文摘要：
Is there a difference in citation rates between articles that were published with links to data and articles that were not? Besides being interesting from a purely academic point of view, this question is also highly relevant for the process of furthering science. Data sharing not only helps the process of verification of claims, but also the discovery of new findings in archival data. However, linking to data still is a far cry away from being a "practice", especially where it comes to authors providing these links during the writing and submission process. You need to have both a willingness and a publication mechanism in order to create such a practice. Showing that articles with links to data get higher citation rates might increase the willingness of scientists to take the extra steps of linking data sources to their publications. In this presentation we will show this is indeed the case: articles with links to data result in higher citation rates than articles without such links. The ADS is funded by NASA Grant NNX09AB39G.
Citing data and software is a means to give scholarly credit and to facilitate access to research objects. Citation principles encourage authors to provide full descriptions of objects, with stable links, in their papers. As Jupyter notebooks aggregate data, software, and other objects, they may facilitate or hinder citation, credit, and access to data and software. We report on a study of references to Jupyter notebooks in astronomy over a 5-year period (2014-2018). References increased rapidly, but fewer than half of the references led to Jupyter notebooks that could be located and opened. J…
The indicator Citation Swing Factor (CSF) has recently been developed to measure this diffusion process quantitatively on the basis of h-core citations, excess citations and total citations. The observed or experimental value of CSF as followed from the basic definition is (dθ/dε), which resulted (-R3/he2) based on a theoretical calculation, where R2, h2 and e2 indicate total citations, h-core citations and excess citations respectively. The later expression indicates the expected or theoretical value of CSF. This paper found out (dθ/dε) for Indian physics research output appeared in selective…
We discuss current efforts behind the curation of observing proposals, archive bibliographies, and data links in the NASA Astrophysics Data System (ADS). The primary data in the ADS is the bibliographic content from scholarly articles in Astronomy and Physics, which ADS aggregates from publishers, arXiv and conference proceeding sites. This core bibliographic information is then further enriched by ADS via the generation of citations and usage data, and through the aggregation of external resources from astronomy data archives and libraries. Important sources of such additional information are…
Efforts to make research results open and reproducible are increasingly reflected by journal policies encouraging or mandating authors to provide data availability statements. As a consequence of this, there has been a strong uptake of data availability statements in recent literature. Nevertheless, it is still unclear what proportion of these statements actually contain well-formed links to data, for example via a URL or permanent identifier, and if there is an added value in providing such links. We consider 531,889 journal articles published by PLOS and BMC, develop an automatic system for …
Where appropriate repositories are not available to support all relevant astronomical data products, data can fall into darkness: unseen and unavailable for future reference and re-use. Some data in this category are legacy or old data, but newer datasets are also often uncurated and could remain "dark". This paper provides a description of the design motivation and development of Astrolabe, a cyberinfrastructure project that addresses a set of community recommendations for locating and ensuring the long-term curation of dark or otherwise at-risk data and integrated computing. This paper also …
There exist huge chunk of academic items receiving no citation years after years and remaining beyond the veil of ignorance of the academic audience. These are known as uncited items. Now, the question is, why a paper fails to get citation? The attribute of incapability of receiving citation may be termed as Uncitedness. This paper traces brief history of the concept of uncitedness sprouted first in 1964 in an article entitled Cybernetics, homeostasis and a model of disease by Gerson Jacobs. The concept of uncitedness was scientometrically first explained by Garfield in 1970. The uncitedness o…
Metrics based on reference lists of research articles or on keywords have been used to predict citation impact. The concept behind such metrics is that original ideas stem from the reconfiguration of the structure of past knowledge, and therefore atypical combinations in the reference lists, keywords, or classification codes indicate future high impact research. The current paper serves as an introduction to this line of research for astronomers and also addresses some methodological questions of this field of innovation studies. It is still not clear if the choice of particular indexes, such …
Standardizing and incentivizing the use of digital object identifiers (DOIs) to aggregate and identify both data analyzed and data generated by a research project will advance the field of astronomy to match best practices in other research fields like geosciences and medicine. Increase in the use of DOIs will prepare the discipline for changing expectations among funding agencies and publishers, who increasingly expect accurate and thorough data citation to accompany scientific outputs. The use of DOIs ensures a robust, sustainable, and interoperable approach to data citation in which due cre…
This paper calibrates how metrics derivable from the SAO/NASA Astrophysics Data System can be used to estimate the future impact of astronomy research careers and thereby to inform decisions on resource allocation such as job hires and tenure decisions. Three metrics are used, citations of refereed papers, citations of all publications normalized by the numbers of co-authors, and citations of all first-author papers. Each is individually calibrated as an impact predictor in the book Kormendy (2020), "Metrics of Research Impact in Astronomy" (Astron Soc Pac Conference Series Monograph 8, San Fr…
F1000 recommendations as a new data source for research evaluation: A comparison with citations
F1000是生物和医学研究的出版后同行评议服务。F1000旨在推荐生物医学文献中的重要出版物，从这个角度来看，F1000可能是一个有趣的研究评估工具。通过将完整的F1000建议数据库与Web of Science书目数据库相连接，我们能够对F1000建议和引文进行全面的比较。我们发现，生物医学文献中约2%的出版物至少获得一项F1000推荐。推荐出版物平均收到1.30条推荐，90%以上的推荐是在出版物出版后半年内给出的。事实证明，F1000推荐和引用之间存在明显的相关性。然而，这种相关性相对较弱，至少弱于期刊影响力和引用之间的相关性。需要进行更多的研究，以确定在评估出版物的影响方面，建议和引用之间存在差异的主要原因。
The general purpose of a scientific publication is the exchange and spread of knowledge. A publication usually reports a scientific result and tries to convince the reader that it is valid. With an ever-growing number of papers relying on computational methods that make use of large quantities of data and sophisticated statistical modeling techniques, a textual description of the result is often not enough for a publication to be transparent and reproducible. While there are efforts to encourage sharing of code and data, we currently lack conventions for linking data sources to a computational…
This paper measures social media activity of 15 broad scientific disciplines indexed in Scopus database using Altmetric.com data. First, the presence of Altmetric.com data in Scopus database is investigated, overall and across disciplines. Second, the correlation between the bibliometric and altmetric indices is examined using Spearman correlation. Third, a zero-truncated negative binomial model is used to determine the association of various factors with increasing or decreasing citations. Lastly, the effectiveness of altmetric indices to identify publications with high citation impact is com…
Government funding agencies and foundations tend to perceive novelty as necessary for scientific impact and hence prefer to fund novel instead of incremental projects. Evidence linking novelty and the eventual impact of a grant is surprisingly scarce, however. Here, we examine this link by analyzing 920,000 publications funded by 170,000 grants from the National Science Foundation (NSF) and the National Institutes of Health (NIH) between 2008 and 2016. We use machine learning to quantify grant novelty at the time of funding and relate that measure to the citation dynamics of these publications…

Unlike other academic bibliographic databases, Google Scholar intentionally operates in a way that does not maintain coverage stability: documents that stop being available to Google Scholar's crawlers are removed from the system. This can also affect Google Scholar's citation graph (citation counts can decrease). Furthermore, because Google Scholar is not transparent about its coverage, the only way to directly observe coverage loss is through regular monitorization of Google Scholar data. Because of this, few studies have empirically documented this phenomenon. This study analyses a large de…
