  Wang, X. ; Erdelez, S. ; Allen, C. ; Anderson, B. ; Cao, H. ; Shyu, C.-R.: Role of domain knowledge in developing user-centered medical-image indexing.
  In: Journal of the American Society for Information Science and Technology. 63(2012) no.2, S.225-241.
  
  Abstract: An efficient and robust medical-image indexing procedure should be user-oriented. It is essential to index the images at the right level of description and ensure that the indexed levels match the user's interest level. This study examines 240 medical-image descriptions produced by three different groups of medical-image users (novices, intermediates, and experts) in the area of radiography. This article reports several important findings: First, the effect of domain knowledge has a significant relationship with the use of semantic image attributes in image-users' descriptions. We found that experts employ more high-level image attributes which require high-reasoning or diagnostic knowledge to search for a medical image (Abstract Objects and Scenes) than do novices; novices are more likely to describe some basic objects which do not require much radiological knowledge to search for an image they need (Generic Objects) than are experts. Second, all image users in this study prefer to use image attributes of the semantic levels to represent the image that they desired to find, especially using those specific-level and scene-related attributes. Third, image attributes generated by medical-image users can be mapped to all levels of the pyramid model that was developed to structure visual information. Therefore, the pyramid model could be considered a robust instrument for indexing medical imagery.

  Anderson, B.: History of the CONSER program (1986-1994).
  In: Serials review. 21(1995) no.2, S.1-16.
  
  Abstract: CONSER's comprehensive review in 1986 sets the stage for this organizational history. Significant events of the widely acclaimed cooperative serial cataloguing programme are traced through the last decade and focus on the CONSER plan, the programme's governance structure and changes in membership, the CONSER database, serials cataloguing issues, and programme documentation and publications. These developments are viewed as CONSER looks ahead to coordinate with the new programme for cooperative cataloguing, reexamine membership/governance issues, implement USMARC format integration, and address a variety of computer related issues

  Anderson, B.: CD-ROM LANs : a new challenge for reference librarians.
  In: 13th National Online Meeting. Ed.: M.E. Williams. Medford, NJ : Learned Information Inc., 1992. S.31-36.
  
  Abstract: Discusses the compatibility of CD-ROM databases and local area networks with notes on: troubleshooting, daily maintenance, CD-ROM databses versus traditional printed services, user training, and the burnout and stress which library staff face. In light of tightening budgets and limited space, LANs are challenging traditional book and periodical budgets, and placing new demands on available library resources and space.

  Anderson, B.: Expert systems for cataloging : will they accomplish tomorrow the cataloging of today?.
  In: Cataloging and classification quarterly. 11(1990) no.2, S.33-48.
  
  Abstract: The motivation of decreasing cataloging costs by minimizing the role of the professional librarian in the cataloging process ha led to experiments in the application of expert systems to cataloging. Systems have been developed to accomplish specific elements of the cataloging process through human-machine interface or through automatic reading and interpretation of title pages. All of the systems developed thus far require a human cataloger to participate in, monitor, and/or complete the cataloging process. Furthermore, the expert systems developed for descriptive cataloging are based on the logic and rules of AACR2 and its dependence on title page information, neither of which may be relevant in their current form as cataloging comes to terms with electronic publishing and full-text retrieval of information.
