12. A case analysis system comprising: a processor; and a memory coupled to the processor, wherein the memory comprises: a comparison module configured to: receive a new case-based document including at least one static attribute and at least one dynamic attribute, wherein the at least one static attribute is common to a plurality of previously processed case-based documents, and wherein the at least one dynamic attribute is specific to the new case-based document; select a domain for the new case-based document based at least in part on a user input, wherein in the selected domain, a plurality of static domain attributes and a plurality of dynamic domain attributes are structured in different sets based on their occurrence and relevance to the selected domain; receiving the one or more static attributes specific attributes specific to the selected domain of the new case-based document; compare one or more static attributes of the new case-based document with corresponding static attribute of the plurality of previously processed case-based documents; and comparing the at least one dynamic attribute of the new case-based document with corresponding dynamic attribute of the sub-set of case-based documents; and an analysis module configured to: compute a static similarity score for at least one previously processed case-based document based at least in part on a mismatch option, wherein the mismatch option is associated with each new case-based document, wherein the static similarity score is indicative of similarity among static parameters; obtain a sub-set of case-based documents from the at least one previously processed case-based document based on the associated static similarity score, wherein the sub-set of case-based documents represent a group of documents similar to the new case-based document with respect to the one or more static attributes; and evaluate a dynamic similarity score for the sub-set of case-based documents based at least in part on a match category, wherein the match category is associated with each dynamic attribute associated with the selected domain.
16. The case analysis system as claimed in claim 12 , wherein the analysis module selects the sub-set case-based documents from the at least one previously processed case-based document based on a pre-determined threshold static similarity score.
