Semantic Search using knowledge graph : Google

Meet the Knowledge Graph, a brand new information seeking technology that will enrich and forever change the act of “searching”. Google has designed the Knowledge Graph in such a way, that it almost reminds us of artificial intelligence. The Graph will be able to “understand” the relationship between the words submitted into the search query and will not simply view them as a random line of characters.

Google has rolled out a minor update to its Search by Image feature, which will enable the search engine to better detect image subjects and provide users with new and more related content. Google had launched the Search by Image feature last year. 

The feature lets users upload a photo to Google search bar and use the image as a 'search item', or alternatively, use a Google image result to find similar images. Earlier, Google's search by image was able to detect photos, but then very base level. 

But now Google is integrating its Knowledge Graph into Search by Image, which will enable smart searches and provide more relevant information. This means if you upload an image of a flower, Google will not simply provide generic images of flowers but will attempt to find that particular flower. With the incorporation of Knowledge Graph, search by image results will appear as the images below:

This update is considered to be part of what will most likely be a continuously growing set of updates to make the feature the next big thing in search. To know more about the update, click here. Meanwhile, check out Google's video for all the ways you can search using an image:

“The Knowledge Graph enables you to search for things, people or places that Google knows about—landmarks, celebrities, cities, sports teams, buildings, geographical features, movies, celestial objects, works of art and more—and instantly get information that’s relevant to your query,” Amit Singhal, senior vice president of engineering at Google, said in a blog post. “This is a critical first step toward building the next generation of search, which taps into the collective intelligence of the Web and understands the world a bit more like people do.”

Google's launch of Knowledge Graph comes days after Microsoft revamped its own Bing search engine with deeper integration of social networking sites such as Facebook and Twitter. The revamped Bing includes option to feature social results from Facebook and Twitter in searches. Microsoft also added new features to Bing to make the search engine easier to use.
