Abstract
The present invention provides a method and a system for identifying relevant information in a data set. The method involves the identification of nodes of interest in a tree structure. A node of interest is a node that contains information, which is relevant to a pre-defined context. The method further involves the step of iteratively extracting sub-trees from the tree structure and identifying records in the extracted sub-trees. The sub-tree is a hierarchical structure that shows the relationship of each node of interest with its ancestor nodes in the tree structure. Each record is a group of sub-tree nodes and contains at least one node of interest.
