  1. What are We Thinking?: Using Faceted Classification and Tagging to Enhance Subject Access to the Public Mind Elise Dunham The Roper Center for Public Opinion Research University of Connecticut SAA MDOR Meeting August 13, 2014 @elisedunham #saa14 #mdor14

  2. Roper Center Services

  3. Datasets

  4. Question Text, Response Categories, & Marginals

  5. The Power of iPOLL This day in history… Current events Clinton’s visit to UConn=Women in Politics Nixon resignation, August 8, 1974 Civil Rights Act of 1964, July 2, 1964 MH17=Air Safety in Wake of Disaster

  6. The Power of iPOLL Topics: FAMILY EQUALITY SEX GROUPS

  7. Goals Develop system for concept-based classification of manageable content Implement workflows for identifying conceptual links between content at point of acquisition/creation

  8. Benefits of Faceted Classification & Tagging • Flexible & agile • Indexer friendly • End user friendly • “Quick” startup

  9. Iterative Project Steps • Read & learn • The Accidental Taxonomist, Heather Hedden • Simmons GSLIS Taxonomy & Controlled Vocabulary course, Heather Hedden • ICPSR & NYT vocabularies • Concepts: FRSAR, LC FAST, Syntactic Indexing • Develop aboutness model to identify facets

  10. Iterative Project Steps cont’d • Develop controlled set of tags after analyzing: • Current iPOLL Topics • Topics at a Glance • User searches • Develop backward- and forward- compatible infrastructure • Assign tags to content

  11. Methodology Primary source Study Variables Topics Survey Samples Survey questions Types Sample Description Secondary source Press releases Power of iPOLLbriefs

  12. Challenges • Public opinion=inherently controversial • Tensions between theoretical purity & implementation • Survey questions are sometimes shorter than a tweet

  13. Ideas Moving Forward • Tag-a-thon • Outside review • Formal user testing/analysis • Linked data: be ready
