MOTIVATION

“The Semantic Web is not a separate Web but

an extension of the current one, in which

information is given well-defined meaning,

better enabling computers and people to work in cooperation. “ -- Tim Berners-Lee

PERSONAS METHODOLOGY

A persona is the archetype of the ideal group of

users for a certain product/application.

It is used to collect user specific information

(interests, goals, frustrations, etc.).



• Often done on paper

• Based on user interviews

• Containing fictional information

• Difficult to validate the information collected

against real users

• Difficult to select the right users, based on

these personas for the usability tests



What do we need to make it better ?


PERSONAS REVIEWED…

these personas for the usability tests

Microdata & RDFa Microdata

• “mechanism allows machine-readable data to be embedded

in HTML documents in an easy-to-write manner, with an

unambiguous parsing model.”

http://www.w3.org/TR/microdata/

• was initially designed as a simple subset of RDFa and

Microformats, primarily focusing on the core features of RDFa.

RDFa Lite

• “RDFa Lite is a minimal subset of RDFa, consisting of a few

attributes that may be used to express machine-readable data

in Web documents like HTML, SVG, and XML.”

http://www.w3.org/TR/rdfa-lite/

• contains all of the simplicity of Microdata coupled with the

extensibility of and compatibility with RDFa.


Microdata vs. RDFa

Microdata RDFa 1.1 Lite*

w3c working draft, part of HTML5 w3c standard as June 2012

Similar markup

Anyone can define their own custom vocabularies

Not supported datatypes of literals

Not supported XML literals.

Not supported vocab

Not supported prefix


* RDFa 1.0 was XHTML specific.

Microdata & RDFa SOLUTIONS Some existing solutions to annotation the HTML5 template:

Microdata schemas:

http://schema.org/Person

RDFa syntax using some existing vocabularies:

http://xmlns.com/foaf/spec/

http://rdfs.org/sioc/spec/




http://xmlns.com/foaf/spec/

HOW TO IMPROVE IT ?

DEVELOPED MICRODATA SCHEMAS

1. Persona - An archetype representing a fictional person or a

group of persons.

2. Scenario - a collage of events or series of actions and events,

which takes place under certain conditions.

3. Context - The circumstances that form the setting for an event or

a scenario.

4. Disability - Categories of physical or mental disabilities.

5. Other Schemas developed: UsabilityTesting, Task.

These types are developed as extensions to schema.org.


DEVELOPED MICRODATA SCHEMAS

Other existing types have been reused: Person,

Place, Event, Product, ImageObject etc.

Other types might need to be defined: Emotion,

Personality, SoftwareApplication etc.

*it can be viewed as a social role or character of a person.

IN PRACTICE …

• Using the obtained information from the personas document in

order to replicate the desired context

• The context has a direct impact on the user performance on

certain tasks


FUTURE WORK

• Automate the process of preparing the personas document

• Automatically validate persona information against real user

information

• Automatically select human (based on social network profile)

for user testing/usability testing


CONCLUSIONS

• We developed

• an HTML5 template for Personas

• several Microdata Schemas

• PersonasOnto ontology

• These vocabularies open new possibilities regarding:

• automatically validation and generation of personas

• linking the data extracted with other data in the spirit of

Linked Data initiative
