Endeca purchase decisionEndeca purchase decision
• Lots of topical searches and poor subject access– Keyword gives too many or too few results
– leads to general distrust– Misunderstanding of authority headings
• No relevancy ranking of results
• Needed more responsiveness (speed)

• “Seams serve as perceptible boundaries that provide points of reference; without such boundaries readers get ‘lost at sea’ and don’t know were they are in relation to anything else; they can’t perceive either the extent of what they have or what they don’t have.”
-Thomas Mann

Future PlansFuture Plans• Ongoing tweaks:
– Continued usability testing; more bling– Relevance ranking algorithms & spell correction thresholds– Additional browsing options
• Endeca 2.0 ideas– FRBR-ized display (using OCLC work identifier)– Natural language entry points– Patron-generated refinements (folksonomies?)– Enrich records with supplemental Web Services content – more
usable TOCs, book reviews, etc.– The death of authority searching (not authority work!)– More integration with QuickSearch, other data repositories, and
third-party discovery tools: pointing content outward– Using Endeca for more kinds of content
