The Smart Subjects tool attempts to increase broader user discovery of relevant library resources by serendipitously recommending library subjects related to a user\'s search query. The prototype tool uses large locally created subject indexes consisting of rich topical keyword content harvested from local sources. An OpenSearch interface allows this recommendation service to be integrated flexibly and easily in a variety of web applications.

  • Smart Subjects: Application Independent Subject Recommendations Tito Sierra NCSU Libraries Code4Lib 2007
  • Outline
    • Concept
    • Motivation
    • Smart Subjects Applications
    • How it Works
    • Strengths and Weakness
    • Future Plans
  • Smart Subjects Concept
    • Input:
      • User search query
    • Output:
      • A list of related library subjects
  • Smart Subjects Concept
    • Input:
      • User search query
    • Output:
      • A list of related library subjects
    • Basically a subject recommendation engine.
  • Example 1
    • Input:
    • music therapy
    • Output:
    • Music
    • Curriculum & Instruction
    • Education
    • Communication & Media
    • Psychology
    • Biochemistry
  • Example 2
    • Input:
    • asymptotic stability
    • Output:
    • Bioinformatics & Biomathematics
    • Statistics
    • Mathematics, Science & Technology Education
    • Mathematics
    • Computer Science
    • Aerospace Engineering
  • Example 3
    • Input:
    • illegal immigration
    • Output:
    • Criminology
    • Political Science
    • Public Administration
    • Biology
    • Zoology
    • Industrial Engineering
  • Example 3
    • Input:
    • illegal immigration
    • Output:
    • Criminology
    • Political Science
    • Public Administration
    • Biology
    • Zoology?
    • Industrial Engineering
  • Motivation
    • Search log analysis:
    • standard, international economic development, fines, dissertation abstracts, music therapy, ACM, wolfcopy, Oxford English Dictionary, audio, illegal immigration, schedule, interlibrary, datamonitor, chemistry, JAMA, CRC, photography, vision, wiley, ciation builder, job, academic search elite, ria, film studies, career development, sanborn maps, citation index, iee, history, industry analysis, scholarly journals, ethics, spss, petition, animal behavior, psych info, repository, ENR, diabetes, data, lrl, cancer, textbooks, wharton, Christian Science Monitor, ITTC, blah, PubMed, time magazine, nutrition, DVD, questia, conductive heat transfer, sage, newspaper
  • Motivation
    • Search log analysis:
    • Lots of topical subject queries in the long tail!
    • standard, international economic development , fines, dissertation abstracts, music therapy , ACM, wolfcopy, Oxford English Dictionary, audio, illegal immigration , schedule, interlibrary, datamonitor, chemistry , JAMA, CRC, photography , vision, wiley, ciation builder, job, academic search elite, ria, film studies , career development, sanborn maps, citation index, iee, history , industry analysis, scholarly journals, ethics , spss, petition, animal behavior , psych info, repository, ENR, diabetes , data, lrl, cancer , textbooks, wharton, Christian Science Monitor, ITTC, blah, PubMed, time magazine, nutrition, DVD, questia, conductive heat transfer , sage, newspaper
  • Motivation
    • Existing work:
    • Subject Browse portal at NCSU
  • Subject Browse at NCSU
    • Locally developed subject classification launched in Fall 2005
    • 100 subject nodes in 12 top-level categories
    • Subject nodes influenced by the university curriculum (e.g. Crop Science)
  • Subject Browse at NCSU
  • Subject Browse at NCSU
  • Smart Subjects Applications
    • Quick Search integration
    • OpenSearch interface

  • How it Works
    • Harvest available institutional data
      • Course catalog descriptions
      • Faculty publications citations
    • Create “text extract” representations for each academic department on campus
    • Index the text extracts
    • Retrieval interface queries indices
    • Retrieval algorithm crosswalks academic departments to library subject classification
  • How it Works
  • How it Works
  • How it Works
  • Technology Used
    • SWISH-E for indexing
    • PHP for retrieval processing/scoring
  • Strengths
    • Application and collection independent
    • Subject recommendations can be integrated in any library search application
    • Encourages broader, serendipitous resource discovery
  • Weaknesses
    • False positives (bad recommendations)
    • Zero hits (no recommendations)
  • Future Plans
    • Deploy new uses of Smart Subjects tool
      • Database Advisor
    • Increase the size of subject indices
      • Article table of contents data
      • Backlog of course descriptions
    • Gauge interest for a community subject recommendation platform
