Discovery Background
– Quickly– By small development teams– Using rudimentary relevance algorithms built around
searching article titles and words within the full text– Often as a side project for companies who invest
more technical resources into ILS
First generation discovery services were developed:

EDS Background
– Years in the making– Extraordinary technical development resources pre-launch – By far the main technical focus of EBSCO post launch
(EBSCO is not diverted by ILS, instead choosing to partner with existing ILS vendors):
• 330 of 424 developers & software engineers working on EDS as of 2014
– Sophisticated relevance and value ranking algorithms refined through unparalleled end user testing
EDS is next generation technology:

Discovery Service Adoption Worldwide 2014
EBSCO stands as the front-runner, with a long lead of 5,612 library subscribers to EDS.
OCLC reports 1,717 libraries with access to WorldCat Local, though a smaller number use it as their primary discovery interface.
Ex Libris has licensed Primo to 1,407 libraries.
ProQuest reports 673 libraries using Summon.

EBSCO’sRelevance Ranking
The system has the following priorities and has
no bias toward content from any provider:
1) Match on subject headings from controlled vocabularies
2) Match on article titles
3) Match on author keywords
4) Match on keywords within abstracts
5) Match on keywords within full text
Exact Matches: Exact matches are favored over partial matches – considering also the field in which those words appear (abstract vs. full text vs. title, etc.)
Density: The number of times the word(s) appears relative to the size of
the document (more is better) – considering also the field in which those words appear (abstract vs. full text vs. title, etc.)

Evaluating the Central Index
• Is the indexed content a good fit?– Inclusion of your journals titles and holdings– Inclusion of your subscribed databases
• Richness of metadata• Ability to incorporate desired content in the
future

Concept-based Search
• EDS includes content with high-quality subject indexing using different specialized vocabularies
• Unfortunately, user search terms and precise subject indexing terms do not always align
• Opportunity exists to better leverage subject indexing for keyword-based discovery in EDS
