This meeting is being held as part of the Raising the Floor Consortium. The Raising the Floor membership agreement, in particular its IPR policy, applies to the contents of the meeting.
What are current practices of describing context information such as: environment, situation, time, location?
What is the relevant literature?
What research projects can we learn from?
What are relevant standards?
(by Jim Tobias)
I wonder if WHO’s International Classification of Functions is relevant to this task force:http://apps.who.int/classifications/icfbrowser/
ICF is a recognized categorization of 4 dimensions (BODY FUNCTIONS, BODY STRUCTURES, ACTIVITIES AND PARTICIPATION, and ENVIRONMENTAL FACTORS) that is intended to explain the concept of disability in terms of roles and participation.
The last 2 dimensions capture at least some of what we may be looking for; for example:
It’s not principally technological in its orientation – in fact, it could be criticized on how it treats the use of technology – but it is the conceptual framework most used in international disabilities research, and thus has a certain amount of credibility and familiarity. Even if ICF does not become our main schema, we might do well to develop at least some parallel references to it.
First, it is important to share a common understanding of the notion of context. The attached Table presents a quite common classification of the types of context proposed by Stefan Poslad. In essence, 6 types are identified related with the questions: what, who, where, when, how it is accessed and why it is useful. At a higher level, the Table groups the above questions into four categories, i.e.: Physical, Human, ICT, Goal.
In accordance with this categorization, we defined a similar subclass hierarchy for the Condition class of the User Profile Ontology (http://wiki.gpii.net/index.php/File:Conditions_v4.png - more details:http://wiki.gpii.net/index.php/Ontologies).
With respect to context description per se, a recent review paper on context modeling (and reasoning) is the following: http://dx.doi.org/10.1016/j.pmcj.2009.06.002
If you do not have access via the above link, you may find a pre-print version here: http://www.perada.eu/documents/articles-perspectives/survey-context-modeling-reasoning-techniques.pdf
In summary, the major modeling approaches are: key-value models, markup models, domain-focused models, object-role based models, ontology-based models and hybrid context models.
For the ontology-based model, notable are the SOUPA ontologies (Standard Ontologies for Ubiquitous and Pervasive Applications - http://cobra.umbc.edu/ont/soupa-ont.tar.gz) - although quite old - which may be considered as an upper-ontology framework for developing context-aware systems.
HDM: Create a table in the GPII Wiki for collecting context-describing properties from various standards, technologies and projects.
Fill table at http://wiki.gpii.net/index.php/Context_Properties with information from other projects and standards:
