Advances in sensor technology, wireless communication, and mobile

devices lead to the proliferation of sensors in our physical

environment. At the same time detailed digital models of buildings,

towns, or even the globe become widely available. Integrating the

huge amount of available sensor data into spatial models results in

highly dynamic models of the real world, often called context models.

A wide range of applications can substantially benefit from common

context models. However, context data is inherently associated with

uncertainty, which has to be taken into account by both context

management systems and applications. Appropriate ontologies, models,

and metrics are needed to specify the quality of context data,

including aspects of degradation, consistency, and trust. Those

concepts are needed on different levels of abstraction, including the

raw sensor data, observable context, as well as the high-level context

derived from other context information by means of reasoning

techniques. In addition, methods and calculi are required to assess

the quality of context data on various levels.

For an integrated context-management approach a framework is needed

that defines the appropriate abstraction levels and that provides

quality mappings between these layers. Other important issues are

application-specific quality concepts and methods to handle uncertain

context data. If context data is to be presented to human users,

appropriate visualizing techniques are required to present the data

together with its quality assessments. On the other hand, if

applications specify what level of degradation they accept, this

information can be used to optimize context management by means of

suitable relaxation techniques.

Research in context management and in particular context quality

requires an interdisciplinary approach. Therefore, the QuaCon Workshop

aims to bring together researchers from various fields to discuss

approaches to context quality and to make a consolidated contribution

towards an integrated way of treating context quality. Topics covered

by the workshop include the following:

- Models for degradation and consistency of context data

- Degradation, spatial ontologies and spatial data mining

- Trust in context data

- Methods and calculi for context quality assessment

- Frameworks and metrics for context quality

- Uncertainty in sensor data processing

- Quality-aware algorithms for context management

- Quality-aware event and stream processing

- Uncertainty in reasoning on context data

- Application-specific context quality and case studies

- Visualization of context quality

Submitted papers must not have been previously published or currently

submitted for publication elsewhere. All papers will be reviewed by

the program committee, and accepted papers will be published in the

post-workshop proceedings in the Springer Lecture Notes in Computer

Science (LNCS) Series. All paper submissions will be handled

electronically. Authors should prepare a Portable Document Format

(PDF) version of their full paper. Papers must be no longer than 10

pages and be formatted according to the LNCS guidelines [1]. Papers

not adhering to these guidelines or the page limit are subject to

rejection without review. The deadline for submitting the paper is

January 31, 2009.
