Objective

Develop an open service archive environment composed by a set of interoperableservices able to

support scholars

  • in interacting with multi-disciplinary archives

  • as members of networked peer communities

Metadata

Digital

Libraries

Education

Tourism

Personalisation

  • The user creates a personal, dynamic hierarchy of folders for the storage of the records that match his information needs

  • The system learns user’s information needs (user profiling)

    by observingthe content of the folders, their organisation and the user behaviour

OAI Open Day for Europe


Personalisation

Donatella’s folder

Digital

Libraries

Metadata

Education

Tourism

Personalisation

  • New data is classified into the right topic folder automatically

The efficiency of the classifier may be improved by exploiting contextual information (e.g. the searching collection)

OAI Open Day for Europe


Donatella castelli istituto di elaborazione della informazione cnr pisa italy

  • Users get recommendations aboutnew documents and new collections that the system judges relevant according to:

    • the specific user information needs

    • the “similar users” information needs

  • Donatella:

  • (content based and collaborative)

Recommender

  • By observing the behaviour of the users and their profiles the system identifies “similar users”

Cooperative work

Shared working space

Very interesting doc

To be read

Cooperative Work

  • A shared working space can be created by groups referencing:

    • user own documents

    • collections

    • recommendations, related links, textual annotations, ratings, …

Will we be able to build a quality service

on the OAI low barrier interoperability framework?

OAI Open Day for Europe


An example

An example

  • Collection description is used by:

    • the end-user to select the collection of interest

    • the collection administrator to select the collections required to build a new collection

    • the document classifier to increase efficiency

    • the recommender system to provide information about new collections

OAI Open Day for Europe


An example1

An example

  • What should a collection description contain:

    • content descripton

    • subject

    • coverage

    • metadata formats

    • metadata language

    • content format

    • digitalized content yes/no

OAI Open Day for Europe


An example2

An example

  • Collection content description: we need to rely on the document description

    DC fields are optional

  • Collection subject: we need to know if the term in the subject field is a classification code, a free term, or term of a controlled vocabulary – the controlled vocabulary – the language of the terms

    DC is unqualified

Will be Cyclades a service for a subset of the OAI registered archives?

Background Tecnology

  • Browse - Desire (University of Dortmund)

  • Personalisation - EUROgatherer (CNR)

  • Cooperative work – CSCW, Cookpit (GMD)

OAI Open Day for Europe


Cooperative work1

Cooperative Work

  • A group of users that often access similar documents may enter into a long term relationship and eventually evolve into a working group (if only they become aware of each other)
