Use Cases from the Charter

Purpose/Goals (maybe these are already covered, maybe more use cases wil arise, these are what we have in charter to motivate our doing)

*Information extracted from large information networks such as the World Wide Web is typically incomplete. The ability to exploit partial information is very useful for identifying sources of service or information. For example, that an online service deals with greeting cards may be evidence that it also sells stationery. It is clear that search effectiveness could be improved by appropriate use of technologies for handling uncertainty.

*Much information on the World Wide Web is likely to be uncertain. Examples include weather forecasts or gambling odds. Canonical methods for representing and integrating such information are necessary for communicating it in a seamless fashion.

*Web information is also often incorrect or only partially correct, raising issues related to trust or credibility. Uncertainty representation and reasoning helps to resolve tension amongst information sources having different confidence and trust levels.

*The Semantic Web vision implies that numerous distinct but conceptually overlapping ontologies will co-exist and interoperate. It is likely that in such scenarios ontology mapping will benefit from the ability to represent degrees of membership and/or likelihoods of membership in categories of a target ontology, given information about class membership in the source ontology.

*Dynamic composability of Web Services will require runtime identification of processing and data resources and resolution of policy objectives. Uncertainty reasoning techniques may be necessary to resolve situations in which existing information is not definitive.

Issues and Relevance to Uncertainty (Summarize how relevant to uncertainty reasoning and representation?) quoting our chapter here could be added "when Boolean truth values are unknown, unknowable, or inapplicable" (possibly links to publications) and also "nightmare caused by proprietary uncertainty representations" possible atempts to solve the problem without uncertainty vagueness model

Assumptions/Preconditions (List the preconditions necessary for this use case to occur, including description of necessary context)

Required resources (List resources, such as data sources, ontologies, needed for scenario)

Associate methodologies that could help (Describe / point to papers ...)

recommend those aspects that are considered most important to be included in a standard representation of vagueness and uncertainty (this the main task of our XG)

Successful End (Describe what happens if this use case is successful)

Failed End (Describe what happens if this use case fails)

Main Scenario (List the sequence of events for the basic course (numbered))

Additional background information or references (Summarize/provide references to information to further describe or characterize use case)

Variations (List the alternatives that will not be further decomposed at this time)
