The World Wide Web search engines like Google and Yahoo are very valuable tools in information gathering. These tools provide all the relevant information of the entered keyword in text, video and audio formats arbitrarily. You can can’t get all these information unanimously using the same keywords, except that, you have to look for these items separately.
In Europe, an improved search technology has been developed in order to change the way we use keywords for search engines. Semantic search represents an emerging paradigm shift in search technology by integrating all the meta data, like text, audio and video files into one search. Using the same keyword, semantic search platform can provide all the related information in all formats. Say, you want to look for information about a famous singer, all information about him will be displayed on your screen. You can listen, watch and read everything about him with just one keyword search.
This search technology uses the concept of Ontology, which is the “collections of agreed metadata terms for a particular field or task, like medicine or accounting”. Semantic search adds more value to your search in that every bit of information is defined by potentially dozens of meaningful concepts.
