Mobile devices have very limited input/output functionality

Mobile users face time-critical, goal-driven tasks Looking for a nearby gas station

Getting battlefield status updates

Mobile users are subject to more distractions Driving through busy intersections

Talking to colleagues

Facing enemy fire

… All this argues for the development of context-aware semantic web solutions

MotivationsMotivations

VisionVision

A collection of easily customizable, context-sensitive agents

Capable of leveraging any Web service

…with the proper semantic markup… Capable of leveraging contextual ontologies

Capable of eliciting, learning and re-using user preferences to

Tailor outgoing requests (“pull”) and carry out tasks in a (semi)autonomous manner “Launch and forget”

Anticipate future user needs/filter incoming information (“push”)

…and, above all, doing in so in a useful, unobtrusive manner

Technology has to be invisible

Specific ObjectivesSpecific Objectives

Extend Semantic Web tools and ontologies in support of:

Civilian mobile Internet scenarios: Approaching 1 billion mobile phone users worldwide

Ideal to promote the broad uptake of Semantic Web technologies In house expertise and ideal evaluation environment – CMU’s campus

Campus as “everyday life microcosm”

Military mobile context-aware scenarios DoD scenarios to be identified in the context of the 2002 DAML

Experiment

Planned Activities in 2002Planned Activities in 2002

Campus-based Semantic Web demonstrator that leverages CMU’s Wireless LAN and location-tracking technology Ideal for rapid prototyping and early evaluation

Contextual attributes: Location, calendar activities, weather, social context, etc.

Context-sensitive preferences

Work:

DAML-S service descriptions and editing tool (in collaboration with others) Specialized context-aware agents Both push and pull functionality Reusable rule-based preferences

2002 DAML Experiment

What we Plan to Deliver in 2002What we Plan to Deliver in 2002

Extensions of DAML+OIL ontologies and DAML-S service descriptions Capturing contextual attributes

Capturing context-sensitive preferences

Mobile service descriptions and specialized service editing & publishing tool(s)

Demonstration and evaluation of Semantic Web context-aware applications on CMU’s campus

Contribution to 2002 DAML Experiment e.g. Context-aware message filtering

Progress MetricsProgress Metrics

Usability as the ultimate success criterion How difficult/easy is it to edit and publish new services?

How difficult/easy is to customize the agents?

Are the ontologies capable of properly capturing user preferences?

Are the resulting services actually helpful…or are they just annoying?

Scalability Ability to interface with new mobile Internet services

Interactions with other DAML groups DAML-S, rules, other relevant ontologies
