A #citylis 2014-2015 Term 1 Twitter Archive

This file contains an archives of Tweets corresponding to the #citylis hashtag during Term 1 of the 2014-2015 academic year (case not sensitive). #citylis is the hashtag used by the Library and Information Science scheme at City University London. 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. This file contains 4940 Tweets published publicly and tagged with #citylis between 11/09/2014 20:11 and 12/12/2014 17:16 GMT The Tweets contained in this file were collected using Martin Hawksey’s TAGS 5.1. This is a.xlsx file that 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. This dataset is shared to encourage legitimate open data research into scholarly activity on Twitter, and complied with the current Twitter Developer Agreement and Policy at the time of its creation. The data included in this dataset is also publicly accessible via the Twitter Search API; this means that unless individual tweets or accounts were deleted after publication absolutely all the data included in this dataset is already publicly, freely, openly and easily accessible elsewhere via Twitter Search. Student participants of #citylis used the hashtag in awareness of its public nature; an introductory workshop to Twitter was offered during Induction Week. Students were encouraged to create their own archives and live archives of this hashtag were also used for analysis during computer lab sessions by students taking the DITA (Digital Information and Technology Architectures) core module. Further reuse of this dataset is responsibility of the user and must comply with the current Twitter Developer Agreement and Policy. 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 the archived hashtag during the indicated period, and is shared for comparative and indicative educational and research purposes only.
