Microsoft will be announced a major revision in the future, Google also gets involved. Yesterday, Google announced the latest search function mapping knowledge (Knowledge Graph) on its official blog. Google search page on the right side adds great length of more definitive results from changes in the past text-based entry in the search results presentation, may be the most significant since a Google search on-line change.

Google previous text-based search methods, the default search page shows ten entries, although it contains links, images and other elements of the page preview, but still requires the user to read the page to judgment. The new on-line knowledge map is a richness and intuitive content, which is integrated in the right column of the search page, users can provide maps, a variety of knowledge Wikipedia entry and so on.

Knowledge Mapping undoubtedly bring great convenience for people. For example, a user searches for "taj mahal" (Taj Mahal) time, Google maps will show you the map location of the Taj Mahal, the Wikipedia description, construction-related knowledge (height, opening hours, designers, etc.), but also given the same name and taj mahal casino figures and other information, compared to the original text-based search results presentation, greatly enhance the user experience.

Behind the map with a strong knowledge repository support. Google acquired in 2010 the Metaweb, which is a focus on information on how to contact each other company, and ultimately can provide more efficient than keyword search algorithm. Google uses Metaweb technologies to Freebase, Wikipedia, CIA World Factbook and other public resources and their search for information as a database, knowledge mapping can cover all aspects.

Google Knowledge gallery on the US line will be this week, but in the early stages only supports English. But Google has been a rapid advance of the company, I believe that this innovative global popularity soon, we'll see.
