Citation studies in the humanities

  1. 1. Citation studies in the humanities Chris Alen Sula School of Information & Library Science Pratt Institute #DH2013 / Citation studies in the humanities / @chrisalensula @thisismmiller Matt Miller NYPL Labs New York Public Library
  2. 2. Background ‣ scholarly communication — the processes by which scholars share their findings, both formally (e.g., articles) and informally (e.g., tweets, letters, blogs) ‣ bibliometrics — methods for analyzing citation behaviors #DH2013 / Citation studies in the humanities / @chrisalensula @thisismmiller ‣ Bibliometrics is largely based on studies of scientific and technical corpora (Hérubel and Buchanan, 1994; Lamont, 2000), with relatively few studies in the humanities (cf. Ardanuy, 2013). (Yan & Ding, 2012)
  3. 3. Citation networks #DH2013 / Citation studies in the humanities / @chrisalensula @thisismmiller Rosvall & Bergstrom (2007)
  4. 4. Bibliometrics & humanities: Why so little? ‣ lack of data (Linmans, 2010), especially for ‣ monographs (Hammarfelt, 2011), which still form the backbone of humanities work (Larivière, et. al., 2006) ‣ older sources, which humanists cite with greater frequency than scientists (Heinzkill, 1980) ‣ lack of citations, comparatively speaking ‣ Humanists cite each other less frequently than scientists (Heinzkill, 1980; Swales, 1990; Hellqvist, 2010). ‣ Multi-authored articles are rare (Price, 1966; Pao, 1981, 1982; Sievert and Sievert, 1989; Wiberly, 1989), around 1.06 authors per article from 1980– 2007 (Linmans, 2010). ‣ Humanists do cite and co-author (Leydesdorff, Hammarfelt & Salah, 2011) and Dhers have done citation studies (Smith, 2009). #DH2013 / Citation studies in the humanities / @chrisalensula @thisismmiller
  5. 5. ‣ Humanities discourse differs from scientific discourse. ‣ more integral references, in which authors associate their own views with those they references (Swales, 1990; Hyland, 1999; Harwood, 2008) ‣ more negative references, which object to other authors’ claims (Meadows, 1974; Brooks, 1985; Cano, 1989). ‣ The mere fact that one humanist cites another says nothing about type or significance of their relationship. ‣ Understanding and tracking these these relationships would give us a richer, more nuanced view of the humanities. Part of that data can come from reference contexts, part from extra- citational information (mentions, likes, real-world relationships, etc.). #DH2013 / Citation studies in the humanities / @chrisalensula @thisismmiller Bibliometrics & humanities: Why so little?

  8. 8. Our tool: extraction #DH2013 / Citation studies in the humanities / @chrisalensula @thisismmiller ‣ Layout recognition used to extract citations and surrounding context (usually 1–2 sentences)
  9. 9. Our tool: classification ‣ Naïve Bayes classifier using NLT #DH2013 / Citation studies in the humanities / @chrisalensula @thisismmiller sample from positive training set ‣extensively discussed by ‣useful discussion ‣indebted to ‣groundbreaking work ‣result confirms the hypothesis sample from negative training set ‣contra ‣appears to overlook ‣fail to account for ‣problematic ‣is unable to
  10. 10. Data & results #DH2013 / Citation studies in the humanities / @chrisalensula @thisismmiller ‣ articles sampled for this study ‣ results of citation tool applied to sample set
  11. 11. Polarity results by discipline #DH2013 / Citation studies in the humanities / @chrisalensula @thisismmiller
  12. 12. Broader patterns? ‣ citation frequency x polarity #DH2013 / Citation studies in the humanities / @chrisalensula @thisismmiller
  13. 13. Future directions ‣ further manual inspection of articles to determine the reliability of extraction and classification ‣ further training of the sentiment classifier on larger corpora ‣ measures of inter-rater reliability for classification ‣ support for more document layouts ‣ crowdsourced PDF analysis & classifier training #DH2013 / Citation studies in the humanities / @chrisalensula @thisismmiller
