Query: Graph based Question Answering System   In today's digital age in the dawning era of big data analytics it is not the
information but the linking of information through entities and actions which
defines the discourse. Any textual data either available on the Internet off
off-line (like newspaper data, Wikipedia dump, etc) is basically connect
information which cannot be treated isolated for its wholesome semantics. There
is a need for an automated retrieval process with proper information extraction
to structure the data for relevant and fast text analytics. The first big
challenge is the conversion of unstructured textual data to structured data.
Unlike other databases, graph databases handle relationships and connections
elegantly. Our project aims at developing a graph-based information extraction
and retrieval system.
