User wg objectives and activities
User WG Objectives and Activities

DL.org All Working Groups Meeting, Rome, 26-28 May 2010

User interoperability
User Interoperability

User Interoperability Definition

Interoperability of DLs/DLSswith regard to what is captured within each DL/DLS about users

Interoperability of usersthrough their use of the DL/DLS

User Interoperability Issues

Interoperability of DLs/DLSs with respect to users

user modeling, user profiling, user context, user management

Interoperability of users

collaboration, participation, privacy

DL.org All Working Groups Meeting, Rome, 26-28 May 2010

Interoperability of dls dlss with respect to users 1 3
Interoperability of DLs/DLSs with respect to users (1/3)

  • The “object” of interoperation

    • can be arbitrary

    • can be an attribute of the user (e.g., user credentials, user demographics)

    • can be simple (e.g., keywords)

    • or complex in structure (e.g. ontologies, queries, layouts)

    • can be at the data or at the model/schema level

DL.org All Working Groups Meeting, Rome, 26-28 May 2010

6


Interoperability of dls dlss with respect to users 2 3
Interoperability of DLs/DLSs with respect to users (2/3)

  • The “purpose” of interoperation

    • preserving user characteristics across systems (transparent user mobility from one system to the next)

    • mapping user characteristics from one system to the next (non-transparent user mobility)

    • integrating user characteristics maintained about the same user in two different systems

DL.org All Working Groups Meeting, Rome, 26-28 May 2010

7


Interoperability of dls dlss with respect to users 3 3
Interoperability of DLs/DLSs with respect to users (3/3)

  • Use cases by combining “objects” and “purposes”

    • consolidating a user’s preferences as perceived from his/her presence in multiple systems

    • retaining the user’s access rights as the system transfers him/her to another system

DL.org All Working Groups Meeting, Rome, 26-28 May 2010

Model profile heterogeneity example
Model/Profile Heterogeneity Example

  • Donatella@DL1:

    • “Research Infrastructures”  0.9

    • “Swimming”  0.3

  • Donatella@DL2:

    • “Research Infrastructures” ≤ “Swimming”

  • Contradicting or Incomparable?

  • Context dependent?

  • Reconciliation approach?

    • E.g., More info and stronger statement in DL1

DL.org All Working Groups Meeting, Rome, 26-28 May 2010

User modeling
User Modeling

  • User modeling: creating a user model for a DL that represents essential information about users

  • Interoperable user models: enable propagation of user information across different DLs

  • State-of-the-art approaches/best practices

    • Shared Format Approach, e.g., General User Model Ontology (GUMO)

    • Conversion Approach, e.g., Schema Mapping of Generic User model Component (GUC)

DL.org All Working Groups Meeting, Rome, 26-28 May 2010

10


User profiling
User Profiling

  • User profiling: collecting information about a user in order to generate user's profile, depending on the current user model

  • User profiling interoperability: supporting mechanisms of reconciliation of different/conflicting user profile characteristics

  • State-of-the-art approaches/best practices

    • Instance Mapping of Generic User model Component (GUC)

DL.org All Working Groups Meeting, Rome, 26-28 May 2010

11


User context
User Context

  • User context: “external” factors affecting user profiles regarding user interactions with a DL

  • User context interoperability: supporting compliant context descriptions and interpreting user information in a concrete way given the same context

  • State-of-the-art approaches/best practices

    • Unified User Context Model (UUCM)

    • Context-passport based on UUCM for cross-system personalization

DL.org All Working Groups Meeting, Rome, 26-28 May 2010

12


User management
User Management

  • User management: managing electronic identities that are strongly associated to users' privileges

  • User management interoperability: heterogeneous DL systems apply concrete, shared, but transparent to the end-user authentication and authorization policies

  • State-of-the-art approaches/best practices

    • OpenID

    • Security Assertion Markup Language (SAML)

    • eXtensible Access Control Markup Language (XACML)

DL.org All Working Groups Meeting, Rome, 26-28 May 2010

13


Interoperability of users
Interoperability of Users

  • Through the DL, users are able to

    • collaborate

    • communicate

    • cooperate

  • The DLS supports them in

    • knowledge sharing

    • sense making

    • identifying new and/or hidden semantics

  • The DLS preserves user privacy and generates a sense of trust

DL.org All Working Groups Meeting, Rome, 26-28 May 2010

14


Collaboration
Collaboration

  • User collaboration: enabling users to directly interact and collaborate with each other or implicitly benefit from the actions of other users in a DL or across different DLs

  • State-of-the-art approaches

    • Indirect collaboration, e.g., collaborative-based filtering, usage statistics, annotations, tags, rankings

    • Direct collaboration, e.g., collaborative tools such as chat, forums

DL.org All Working Groups Meeting, Rome, 26-28 May 2010

15


Participation
Participation

  • User participation: engaging users in active participation in the evolution of a DL, both at the content and the operational level

  • State-of-the-art approaches

    • Social networks

    • Flickr Commons (partner w/ Library Congress + 15 other institutions)

    • Noosphere serving as the PlanetMath project's software platform

DL.org All Working Groups Meeting, Rome, 26-28 May 2010

16


Privacy
Privacy

  • User privacy: controlling the degree to which user make information about their interests and activities public in the context of user communities that DLs support

  • State-of-the-art approaches

    • SemWebDL, that enables the dynamic composition of disparate and autonomous digital libraries while preserving user’s privacy
