| Abstract | Time representation and temporal reasoning plays an important role in time-series analysis and prediction, which involve dealing with varying situations in terms of states of the world evolving with time. Generally speaking, the world in the discourse persists in a given state until some action(s) is carried out, or some event(s) occurs, to change it into another state. This paper presents a framework for prediction and analysis based on time-series of states. It takes a time theory that addresses both points and intervals as primitive time elements on an equal footing as the temporal basis. A state of the world under consideration is defined as a set of time-varying propositions that include properties, facts, actions, events, processes and anything else with Boolean truth-values that are dependent on time. A time-series of states is then defined as a list of states temporally ordered one after another. The framework supports explicit expression of both absolute and relative temporal knowledge. While a formal schema for expressing general time-series of states is given, allowing a time-series of states to be incomplete in various ways, the concept of complete time-series of states is also formally introduced. As the application of the proposed formalism in prediction and time-series analysis, illustrating examples are provided. |

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.
