Google Knowledge Graph of Interconnected Entities & Attributes; Improves Health Search Algorithm, Now List Possibly Related Health Conditions

Google doesn’t understand the search query, however, it only tries to match the words from the query to bring the results. So, how does Google work? Usually Google returns some very good search results, based on the keywords in the phrase and the sites / pages with significant amount of authority on those words and even word groupings, or some synonyms.

Google”s Fellow and SVP Amit Singhal says that Google doesn”t understand the question. “We cross our fingers and hope someone on the web has written about these things or topics.”

Adding, he says, Google works on building “a huge knowledge graph of interconnected entities and their attributes”. The transition from a word-based index to this knowledge graph is a fundamental shift that will radically increase power and complexity.

He explained that the word index is essentially like the index you find at the back of a book: “A knowledge base is huge compared to the word index and far more refined or advanced.”

Freebase was just the starting point: Right now Google is, he said, building the infrastructure for the more algorithmically complex search of tomorrow, and that task, of course, does include more computers. All those computers are helping the search giant build out the Google”s knowledge graph, which now has 200 million entities.”

The graph is actually an encyclopedia with structured information obtained from the web. This will help Google understand your queries, provide answers to complex questions and find more relevant results. What can you do with that kind of knowledge graph (or base)?

Right now, “Google only uses the graph to show a list of related searches for singers, actors, painters etc. As Google improves its infrastructure, the knowledge graph will be used more and more.”

“Type “Monet” into Google Search, for instance, and, along with the standard results, you”ll find a small area at the bottom: “Artwork Searches for Claude Monet.” In it are thumbnail results of the top five or six works by the master. Singhal says this is an indication that Google search is beginning to understand that Monet is a painter and that the most important thing about an artist is his greatest works,” he explains.

In other Google search news, Google announced improvements to its health searches. Now, when you search for a symptom or set of symptoms, you’ll often see a list of possibly related health conditions that you can use to refine your search. The list is generated by Google”s algorithms that analyze data from pages across the web and surface the health conditions that appear to be related to your search.

The list of health conditions you see is aggregated from what”s written on the web about the symptoms you searched. The list is not authored by doctors and of course is not advice from medical experts.

“For example, if you search for [abdominal pain on my right side], you”ll be able to quickly see some potentially related conditions and learn more about them by clicking on the links in the list,” explains google.
