Overview Semantic data organization and tagging Inclusive Universal Access and social tagging  Inclusive Social Tagging Analysis of current Web 2.0 services

Semantic data organization and tagging

Inclusive Universal Access and social tagging  Inclusive Social Tagging

Analysis of current Web 2.0 services

Tagging

Tagging Bringing order to things – organize, search, find Object tag

Bringing order to things – organize, search, find

Social tagging, folksonomy … … … “ tag cloud”

Data organization metadata initiatives coordinated metadata repositories & registries domain ontology taxonomy thesaurus conceptual meta-model logic theory for domain semantics social tagging categories stereotypes formal metadata, standards initial fully developed informal formal weak semantics strong semantics development structured

Universal accessibility A product or service is universally accessible, if it can be used by persons regardless of their capabilities, skills, and characteristics.  high quality of interaction; availability to anywhere, anytime; Life cycle -- requirements, analysis, design (recent) Inclusive Universal Access extension with non technology aspects Inclusion : all people on all levels (intellectual, social, personal…); user involvement in all product/service lifecycle phases Adaptability : usage scenarios flexible to adapt to user requirements, behavior, … Usability : use case focused, smooth experience; guidelines compliance (eg WCAG), privacy, security, reliability

A product or service is universally accessible, if it can be used by persons regardless of their capabilities, skills, and characteristics.

 high quality of interaction; availability to anywhere, anytime; Life cycle -- requirements, analysis, design (recent)

Inclusive Universal Access extension with non technology aspects

Inclusion : all people on all levels (intellectual, social, personal…); user involvement in all product/service lifecycle phases

Adaptability : usage scenarios flexible to adapt to user requirements, behavior, …

Usability : use case focused, smooth experience; guidelines compliance (eg WCAG), privacy, security, reliability

Metadata vs. social tagging Inclusiveness: Not inclusive Entry barriers Inclusive Inclusive All potential users (usually registration required) Important use case for all users No restrictions on tag number / meaning Decentral cooperation and coordination Social tagging All potential users Typical: strict guidelines and rules, Assumptions about the domain Effort required by first-time users. Restricted to a closed circle of persons, committees, and organizations Metadata Inclusiveness of usage Inclusiveness of creation

Inclusiveness:

All potential users (usually registration required)

Important use case for all users

No restrictions on tag number / meaning

Decentral cooperation and coordination

All potential users

Typical: strict guidelines and rules,

Assumptions about the domain

Effort required by first-time users.

Restricted to a closed circle of persons, committees, and organizations

Metadata vs. social tagging Adaptability: Provider effort User effort Adaptable Adaptable Easy adding, editing, retrieval, querying Sometimes restricted to creator Core element of social tagging No restricted dictionary Extension and adaptation are “natural” use cases Social tagging Constrained by rules and guidelines Requires research on extension mechanisms Can be adapted to changing requirements Effort may be significant (bureaucratic control mechanisms) Might break existing applications Metadata Adaptability of usage Adaptability of creation

Adaptability:

Easy adding, editing, retrieval, querying

Sometimes restricted to creator

Core element of social tagging

No restricted dictionary

Extension and adaptation are “natural” use cases

Constrained by rules and guidelines

Requires research on extension mechanisms

Can be adapted to changing requirements

Effort may be significant (bureaucratic control mechanisms)

Might break existing applications

Metadata vs. social tagging Usability: Depends on tools Depends on tools Depends on tools High usability Most important use case  particular caution for usability in tagging services Mostly implemented as Web 2.0 services resembling desktop experience Enabled through provided software service Conceptually simple task, however dependent on software quality Social tagging Depends heavily on quality of tools and documentation provided. Assumptions, rules and restrictions in the underlying domain model Metadata Usability of usage Usability of creation

Usability:

Most important use case  particular caution for usability in tagging services

Mostly implemented as Web 2.0 services resembling desktop experience

Enabled through provided software service

Conceptually simple task, however dependent on software quality

Depends heavily on quality of tools and documentation provided.

Assumptions, rules and restrictions in the underlying domain model

Principles of IST Decentral responsibility, Active participation, Interpersonal exchange, Person centeredness, Universal accessibility Depends on tools Not inclusive Entry barriers Provider effort User effort Depends on tools Inclusive Adaptable High usability

Decentral responsibility,

Active participation,

Interpersonal exchange,

Person centeredness,

Universal accessibility
