Abstract
A present invention provides a method and a system for extracting information related to a pre-defined context from data sets written in semi-structured or unstructured form, such as a natural language text. The information related to the pre-defined context is stored in an information store in accordance with a pre-defined structural arrangement. Further, the individual data values in the extracted information are assigned weights depending on their relevance to attributes of the predefined context. The operation of assigning weights to the structured information provides a measure for comparing the relevance of a plurality of structurally arranged information to the attributes of the pre-defined context.
