web search vs site search 1
Web Search VS. Site Search(1)
  • Web search is OK
    • Most successful at directing users to appropriate web site
  • Survey finds high user satisfaction

web search vs site search 2
Web Search VS. Site Search(2)
  • Notorious site search
  • A Study by Vividence Research
    • Spring 2001, 69 web sites
      • 70% eCommerce
      • 31% Service
      • 21% Content
      • 2% Community
    • The most common problems:

53% had poorly organized search results

32% had poor information architecture

32% had slow performance

27% had cluttered home pages

25% had confusing labels

15% invasive registration

13% inconsistent navigation

slide11
Why?
  • Seek an information resource based on a variety of characteristics
  • A single hierarchical structure approach
    • Hard to develop
    • Bias access

direct search vs faceted search
Direct search VS. Faceted search
  • Keyword search: Allows users to enter any number of words and shows the results as a list of titles in a certain order.
direct search vs faceted search1
Direct search VS. Faceted search
  • Keyword search: Allows users to enter any number of words and shows the results as a list of titles in a certain order.
  • Advanced search: Exposes much of metadata to user in the form of checkboxes and drop-down lists. All facet selections are ANDed together.
direct search vs faceted search2
Direct search VS. Faceted search
  • Faceted search: A successful complement to keyword searching.
    • Organize the structure of results.
    • Show previews of where to go next.
    • Seamlessly integrating free text search within the category structure.
    • Avoid empty results sets.
clustering vs faceted categories
Clustering VS. Faceted categories
  • Clustering refers to the grouping of items according to some measure of similarity.
  • Advantages:
    • Fully automatable.
    • Can be easily applied to any text collection.
    • Reveal new trends in a group of documents.

  • Standard faceted navigation:
    • Items determine which facet labels are shown.
      • Return:
        • Contain that word.
        • Assigned that label.
        • Aggregation of facet labels that are assigned to those retrieved items.
