Keyword Search Retrieval for Structured data using RDF for E-learning application

E-learning is an interactive learning system with a computer through Internet connection. The retrieval of book details by e-learning users is generally difficult, since those data are structured. The structured data face the challenging issues in retrieval process. The schema of the data is not known to the user in order to query, which is also user friendly to the end users. Here E-learning materials may be schema-free or poorly-schematized. In this proposed work, a graphical query formulation language, called MashQL, is used in order to easily query structured data in E-learning application. Even, when the end users have limited technical background they can query and explore multiple data sources. This is the main significance of MashQL. This work aims in introducing semantic keyword search to retrieve the structured data.
