W3C Ubiquitous Web

Workshop on Conversational Applications
— Use Cases and Requirements for New Models of Human Language to Support Mobile Conversational Systems —

18-19 June 2010

Hosted by Openstream, Somerset, NJ, US



A number of developers of conversational voice applications feel that the model of human language currently supported by W3C standards such as SRGS, SISR and PLS is not adequate and that developers need new capabilities in order to support more sophisticated conversational applications.

Workshop Goals

The goal of the workshop is to understand the limitations of the current W3C language model in order to develop a more comprehensive model. We plan to collect and analyze use cases and prioritize requirements that ultimately will be used to identify improvements to the W3C language model. Just as W3C developed SSML 1.1 to broaden the languages for which SSML is useful, this effort will result in improved support for language capabilities that are unsupported today.

The main outcome of the workshop will be the publication of a document that will serve as a guide for improving the W3C language model.

Scope of the Workshop

Submissions must describe (1) requirements and use cases for improving W3C standards for conversational interaction and (2) how the use cases justify one or more of these topics:

Requirements for Participation

Position papers will be the basis for the discussions at the workshop. Individuals wishing to participate must submit a position paper by the date shown below. The program committee will select papers that provide insight into the requirements and use cases for improving the W3C language model.

All workshop attendees must submit a position paper. Papers must be submitted by email to <team-convapps-ws-submit@w3.org> before April 2 April 30.

Position papers must be written in English. Examples may be illustrated with non-English languages with an English explanation. All papers should be 1 to 5 pages, although they may link to longer versions or appendices. Allowed formats are valid HTML or XHTML, PDF, or plain text. Papers in any other format (including invalid HTML/XHTML) will be returned with a request for correct formatting.

Participation in the workshop is conditional upon acceptance of the position paper by the program committee.

Accepted position papers will be published on the public Web page of the workshop. Submitting a position paper comprises a default recognition of these terms for publication.

The Program Committee will ask the authors of particularly salient position papers to explicitly present their position at the workshop to foster discussion. Presenters will be asked to make the slides of the presentation available on the workshop home page in HTML, PDF, or plain text.
