A New Semantic Web Approach for Constructing, Searching and Modifying   Ontology Dynamically
  Semantic web is the next generation web, which concerns the meaning of web documents It has the immense power to pull out the most relevant information from the web pages, which is also meaningful to any user, using software agents. In today's world, agent communication is not possible if concerned ontology is changed a little. We have pointed out this very problem and developed an Ontology Purification System to help agent communication. In our system you can send queries and view the search results. If it can't meet the criteria then it finds out the mismatched elements. Modification is done within a second and you can see the difference. That's why we emphasis on the word dynamic. When Administrator is updating the system, at the same time that updation is visible to the user.
