Conversational Dialog Systems conducts research in automated dialog management including initiatives in natural language based dialog interfaces for navigation and enhancement of e-commerce through direct access to merchandise. The group's main efforts go towards construction of universal and application-specific dialog engines that can manage discourse history and converse in natural language over multiple channels. We build technologies, infrastructure tools and framework for supporting dialog based and customer service related multi-modal applications. Our current projects include extensive use of XML/XSL technology in building conversational interfaces for stock trading and product information systems whose goal is to resolve customer questions about merchandise, services and guide them towards products and services with desired characteristics. Our projects cover a wide range of problems e.g. information retrieval, markup of communication acts, user modeling, parsing, knowledge representation and construction of product databases.
