  Kipp, M.E.I. ; Beak, J. ; Graf, A.M. ; Fox, M.J.: Tagging of banned and challenged books.
  In: Knowledge organization. 42(2015) no.5, S.276-283.
  
  Abstract: We collected the tags associated with the American Library Association's Top 100 Banned / Challenged Books: 2000-2009 on LibraryThing, GoodReads and BiblioCommons and examined the tags for terms that matched the reasons given for challenging the books, the general age ranges assigned to the books, and the subject matter of the books. User tags demonstrated an awareness of censorship issues related to banned or challenged books as well as an awareness of subject areas that were potentially controversial.

  Lu, K. ; Kipp, M.E.I.: Understanding the retrieval effectiveness of collaborative tags and author keywords in different retrieval environments : an experimental study on medical collections.
  In: Journal of the Association for Information Science and Technology. 65(2014) no.3, S.483-500.
  
  Abstract: This study investigates the retrieval effectiveness of collaborative tags and author keywords in different environments through controlled experiments. Three test collections were built. The first collection tests the impact of tags on retrieval performance when only the title and abstract are available (the abstract environment). The second tests the impact of tags when the full text is available (the full-text environment). The third compares the retrieval effectiveness of tags and author keywords in the abstract environment. In addition, both single-word queries and phrase queries are tested to understand the impact of different query types. Our findings suggest that including tags and author keywords in indexes can enhance recall but may improve or worsen average precision depending on retrieval environments and query types. Indexing tags and author keywords for searching using phrase queries in the abstract environment showed improved average precision, whereas indexing tags for searching using single-word queries in the full-text environment led to a significant drop in average precision. The comparison between tags and author keywords in the abstract environment indicates that they have comparable impact on average precision, but author keywords are more advantageous in enhancing recall. The findings from this study provide useful implications for designing retrieval systems that incorporate tags and author keywords.

  Martínez-Ávila, D. ; Olson, H.A. ; Kipp, M.E.I.: New roles and gobal agents in information organization in Spanish libraries.
  In: Knowledge organization. 39(2012) no.2, S.125-136.
  
  Abstract: In a new globalized scenario, the traditional activities of information organization agents in libraries have tended to converge with those from the book industry under the presumption that most traditional library practices are not adequate for the new globalized situation. This article analyzes the nature and consequences for libraries of the links between agents from the book industry and the organizations in charge of the main library information organization systems, both at an international level and in Spain. Some of the agents whose discourses were analyzed include OCLC, the UDC Consortium, BISG, BIC, EDItEUR, DILVE, Google and Amazon. We conclude that there is evidence of an incursion of book industry practices into the information organization practices of OCLC and that collaboration between both sectors will result in an increase in universality and homogenization in library information organization practices without consideration for the nature and specific characteristics of the library and how it differs from the bookstore.

  Kipp, M.E.I.: Tagging of biomedical articles on CiteULike : a comparison of user, author and professional indexing.
  In: Knowledge organization. 38(2011) no.3, S.245-261.
  
  Abstract: This paper examines the context of online indexing from the viewpoint of three different groups: users, authors, and professional indexers. User tags, author keywords, and descriptors were collected from academic journal articles, which were both indexed in PubMed and tagged on CiteULike, and analysed. Descriptive statistics, informetric measures, and thesaural term comparison shows that there are important differences in the use of keywords among the three groups in addition to similarities, which can be used to enhance support for search and browse. While tags and author keywords were found that matched descriptors exactly, other terms which did not match but provided important expansion to the indexing lexicon were found. These additional terms could be used to enhance support for searching and browsing in article databases as well as to provide invaluable data for entry vocabulary and emergent terminology for regular updates to indexing systems. Additionally, the study suggests that tags support organisation by association to task, projects, and subject while making important connections to traditional systems which classify into subject categories.

  Kipp, M.E.I. ; Campbell, D.G.: Searching with tags : do tags help users find things?.
  In: Knowledge organization. 37(2010) no.4, S.239-255.
  
  Abstract: The question of whether tags can be useful in the process of information retrieval was examined in this pilot study. Many tags are subject related and could work well as index terms or entry vocabulary; however, folksonomies also include relationships that are traditionally not included in controlled vocabularies including affective or time and task related tags and the user name of the tagger. Participants searched a social bookmarking tool, specialising in academic articles (CiteULike), and an online journal database (Pubmed) for articles relevant to a given information request. Screen capture software was used to collect participant actions and a semi-structured interview asked them to describe their search process. Preliminary results showed that participants did use tags in their search process, as a guide to searching and as hyperlinks to potentially useful articles. However, participants also used controlled vocabularies in the journal database to locate useful search terms and links to related articles supplied by Pubmed. Additionally, participants reported using user names of taggers and group names to help select resources by relevance. The inclusion of subjective and social information from the taggers is very different from the traditional objectivity of indexing and was reported as an asset by a number of participants. This study suggests that while users value social and subjective factors when searching, they also find utility in objective factors such as subject headings. Most importantly, users are interested in the ability of systems to connect them with related articles whether via subject access or other means.
