EBSCO Discovery Service

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:

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
