3Overview
- Applying Strategic Marketing
- Market Segmentation and Classification
- DELOS Evaluation Forum
- market-based classification
- metrics and evaluation
- development of the Meta-Library
- Helping shape the future agenda
4Strategic Marketing DL Evaluation
- How can these possibly be related?
- Business is customer-centred
- the customer is king
- First Commandment of Marketing
- WHO is buying WHAT and WHY
- Information is user-centred
- the user is king
- First Commandment of Info-Business
WHO is using WHAT and WHYWHO is buying WHAT
and WHY

6Market segmentation
- Most important aspect of strategic marketing
- Market segments must be
- highly similar within
- distinct from other segments
- described in terms of use or purchase
- reachable
- Accuracy of segmentation affects success TQM and
thus of the business

9DL Segmentation Classification
WHO is using WHAT, HOW and WHY
- WHO
- users
- demographics
- interests (subject)
- approaches
- WHAT
- data/collection
- description
- management
- HOW
- technology
- user techn.
- info. tools
- system techn.
- document techn.
- WHY
- uses (purpose)
- encounter type
WHO and WHY predetermine WHAT and HOW
10Generalised Schema for a Digital Library
11Market Segmentation and DL Metrics
- A market segment must be
- highly similar within
- distinct from other segments
- described in terms of use or purchase
- reachable
- A DL evaluation metric
- independent of other metrics
- relevant
- measurable
12Proposed DL Classification and Metrics
- Classification
- Users/uses
- user/uses
- internal, general, education, professional,
research - domain (subject area)
- info encounter
- object seeking, browsing
- purpose
- consume, analyse, synthesize
- Metric
- Users/uses
- user/uses
- number
- distribution
- domain
- distribution
- info encounter
- distribution
- purpose
- distribution
13Proposed DL Classification and Metrics
- Classification
- Data/Collection
- content
- none/partial/full
- audio, video, text
- 2D/3D
- meta-content
- biblio
- indexing/thesaurus /classification
- citation
- management
- rights, work flow, user management, maintenance
- Metric
- Data/Collection
- content
- diversity, age, size, quality (white/grey
literature) - meta-content
- media
- level of detail
- management
- doc. age, growth rate, immediacy, completeness,
maintenance intervals
14Proposed DL Classification and Metrics
- Classification
- technology
- user technology
- doc. creation, disclosure, interface, browsing,
search, printing, group/individual - information access
- retrieval, navigation, filtering, extraction,
text mining - systems structure tech.
- repository, transport models
- document technology
- doc. model, format
- Metric
- technology
- user technology
- information access
- efficiency
- effectiveness
- systems structure tech.
- document technology
15Evaluation of the Scheme
- Creation of a questionnaire from the
classification scheme - Questionnaire A
- What DLs are currently available that can be used
as test collections - Questionnaire B
- What test collections will be needed in the
future - methodology open web-based survey tool designed
by SZTAKI Kovacs Micsik - survey announced via mailing lists
- Outcome
- 3-4 response, 70 from research domain
- scheme appropriate but wording of questions
difficult
16Development of the MetaLibrary
- Extensible survey database
- Registers and classifies each submitted DL
collection - Allows identification of missing research areas
or test collections - Potentially could set the agenda for future
research - Analogy with standard marketing strategy
17Market Extension
18Conclusions Next Steps
- DL evaluation needs a broad and user-centred view
- new DL evaluation scheme
- a hierarchy of user-based metrics
- meta library of DL collections
- http//www.sztaki.hu/delos_wg21/metalib/
- extension of the meta library
- agenda setting for DL research
