| Abstract | We propose an architecture for integrating discourse processing and speech recognition (SR) in spoken dialogue systems. We apply it to a distributed battlefield simulation system used for military training. According to this architecture, discourse functions previously distributed through the interface code are collected into a centralized discourse capability. The Dialogue Manager (DM) acts as a third party mediator overseeing the translation of input and output utterances between English and the command language of the backend system. The DM calls the Discourse processor (DP) to update the context representation each time an utterance is issued or when a salient nonlinguistic event occurs. For task based human computer dialogue systems, the DM consults three sources of nonlinguistic context constraint in addition to the linguistic discourse state: (1) a user model, (2) a static domain model, and (3) a dynamic backend model (BEM). We describe its four step recovery algorithm invoked by DM whenever an item is unclear in the current context or there is an interpretation error, and show how parameter settings on the algorithm can modify the overall behavior of the system from tutor to trainer. This is offered to illustrate how limited (inexpensive) dialogue processing functionality, judiciously selected, and designed in conjunction with expectations for human dialogue behavior can compensate for inevitable limitations in SR, NL processor, the backend software application, or even in the user's understanding of the task or the software system. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
