With the appealing features of cloud computing, cloud becomes an important infrastructure of enterprise IT. A large amount of data is being outsourced to the cloud. Before outsourcing the data is being encrypted. Encryption makes simple but important functionalities like search operations over cloud data difficult. The traditional and efficient plaintext keyword search technique has no effect on encrypted data. The existing searchable encryption schemes support only exact keyword search, not support semantic based search. Hence, the authors propose a search scheme wherein the semantic relationship and synonym of the query keyword are considered with the help of data structures like Semantic Relationship Library (SRL), inverted Index. The result files are displayed in order according to total relevance score.
