A #HEFCEmetrics Twitter Archive

"In metrics we trust? Prospects & pitfalls of new research metrics" was a one-day workshop hosted by the University of Sussex, as part of the Independent Review of the Role of Metrics in Research Assessment. It took place on Tuesday 7 October 2014 at the Terrace Room, Conference Centre, Bramber House, University of Sussex, UK.

This file contains a dataset of 1178 Tweets tagged with #HEFCEmetrics (case not sensitive). These Tweets were published publicly and tagged with #HEFCEmetrics between 02/10/2014 10:18 and 08/10/2014 00:27 GMT.

This file was created and shared by Ernesto Priego (Centre for Information Science, City University London) with a Creative Commons- Attribution license (CC-BY) for academic research and educational use.

The Tweets contained in this file were collected using Martin Hawksey’s TAGS 6.0. This file contains 3 sheets.

Only users with at least 2 followers were included in the archive. Retweets have been included. An initial automatic deduplication was performed but data might require further deduplication. The Time column (D) has times in British Summer Time (BST).

Please note that both research and experience show that the Twitter search API isn't 100% reliable. Large tweet volumes affect the search collection process. The API might "over-represent the more central users", not offering "an accurate picture of peripheral activity" (González-Bailón, Sandra, et al. 2012). It is not guaranteed this file contains each and every Tweet tagged with #HEFCEmetrics during the indicated period, and is shared for comparative and indicative educational and research purposes only.

Please note the data in this file is likely to require further refining and even deduplication. The data is shared as is. The contents of each Tweet are responsibility of the original authors. This dataset is shared to encourage open research into scholarly activity on Twitter. If you use or refer to this data in any way please cite and link back using the citation information above.

《我们所信赖的度量指标？新型研究度量指标的前景与陷阱》为一日研讨会，由萨塞克斯大学（University of Sussex）主办，系“研究评估中度量指标作用独立评审”的配套活动，于2014年10月7日周二在英国萨塞克斯大学Bramber楼会议中心露台会议室举办。

本文件包含1178条带有#HEFCEmetrics（不区分大小写）标签的推文。这些推文于格林尼治标准时间（GMT）2014年10月2日10:18至2014年10月8日00:27期间公开发布，并带有#HEFCEmetrics标签。

本文件由伦敦城市大学信息科学中心的埃内斯托·普列戈（Ernesto Priego）创建并共享，采用知识共享署名许可协议（Creative Commons-Attribution, CC-BY），可用于学术研究与教育用途。

本文件内的推文通过马丁·霍克斯（Martin Hawksey）开发的TAGS 6.0工具采集，文件包含3个工作表。

本归档仅收录粉丝数不少于2的用户发布的推文，已包含转推内容；已执行初步的自动去重，但仍可能需要进一步去重。时间列（D列）采用英国夏令时（British Summer Time, BST）。

请注意，现有研究与实践均表明，推特搜索应用程序编程接口（Twitter Search API）并非100%可靠。推文总量过大会影响搜索采集流程，该接口可能‘过度凸显核心用户’，无法‘准确呈现边缘性活动’（冈萨雷斯-巴伊隆等人，2012）。无法保证本文件包含指定时间段内所有带有#HEFCEmetrics标签的推文，本文件仅用于对比性、指示性的教育与研究目的。

请注意本文件中的数据可能需要进一步优化甚至再次去重，数据按“现状”提供。每条推文的内容责任由其原作者承担。本数据集旨在推动针对推特学术活动的开放研究。若以任何方式使用或引用本数据，请遵循前文的引用信息进行标注并附上相关链接。
