Entity Disambiguation is the problem of distinguishing or differentiating between different things or entities that have the same name. Take the example of George Bush — there are six different George Bushes‘ including two US presidents on Wikipedia. Similarly there are ten different Michael Jordans‘ too ! You can also have cases where different types of entity have the same name — take the case of apple. It also refers to the fruit as well as the company. Last month Google rolled out a feature, where they distinguish and disambiguate entities when you start typing a query. You can read more about it on my research lab’s website where I have short blog on “Entity Disambiguation in Google Auto-complete“.
