title: How to create semantic search engine using OWL+mysql
body: <p>I'm a beginner in Ontology but I searched a lot for my case and couldn't find a good answer.</p>
  
  <p>my case is :
  1- I've a big database which contains around 4 million records.
  2- I've an owl file for the database schema.</p>
  
  <p>now I need to establish a semantic search engine using the mapreduce, I read a lot in Jena and protege </p>
  
  <p>I don't know how to solve this problem as my database is very big.</p>
  
  <p>I tried to use Cellfie and Ontop plugins for Protege 5 , but Cellfie couldn't load my big excel file ( although I increased the Java heap), also Ontop just query my database without asserting the individuals of my classes !</p>
  
  <p>so is there a way to create a semantic search engine with mysql database ? if the answer is no, how can I combine the data in the database with the owl file ????</p>
