Can someone comment on how to use knowledge graphs for search? I have seen some applications in NLP but I am curious how it can tie in with traditional search.
AFAIK, in Google’s case instant answer cards come from the Google’s knowledge graph, not search results. I.e. if you see some info rendered on top of search results or on the side, most likely it’s from the knowledge graph.
You can use a knowledge graph for query expansion. For example, if the query is "Dan Dan Noodles", you can expand that to "Asain Noodles", "Chinese", "Tan Tan Noodles" to achieve higher Recall in your results.
