Hi, I think one problem of the existing method is that, to query on the RDF files or similar structures, we have to form SQL like queries. However, for searching in the text files, we only need to type several keywords. Can we combine the two methods and how can we combine the two methods. For instance, i only need to enter some keywords. Then, the system can handle the left process. Why do we have to learn some SQL like language for searching in the Semantic Web.
