| Abstract | Data mining is concerned with analyzing large volumes of unstructured data to discover interesting regularities or relationships which in turn lead to better understanding of the underlying processes. Existing algorithms like association rule mining, incremental mining and frequent pattern mining can be used to find out valid periodic pattern and it can't be used to find out peculiar data. In this paper, two algorithms namely Peculiarity factor algorithm and Chi-Square test algorithm are used to find out peculiar data from a temporal database which is presented in vertical format. If peculiar data are found in two different relations there is need to use a value in a key as the relevance factor in order to find out the relevance between those relations. Thus a new dataset is formed from an existing dataset after the removal of peculiar data. From a new dataset Periodic Patterns were found by applying four phase algorithms namely singular periodic pattern mining, multi-event periodic pattern mining, complex periodic pattern mining and asynchronous sequence mining. Our proposed work focuses on prediction of time series data. This can be done with the help of correlation estimation. After determining strong and weak attributes using correlation estimation only strong attributes are considered to find out how each attribute is correlated with other attributes. Based on the correlation we predicted the required attribute values under given test conditions. Based on the prediction output precision and recall are calculated and hence accuracy is measured. Experimental results on real-life datasets demonstrate that the proposed algorithm is effective and efficient to predict the time series data. |

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.
