Analyzing the results, Munster estimated that Siri is more than two years behind Google giving it a grade D compared to B+ for Google.
Notably, Siri uses Google to answer 60% of its queries. The rest of the answers are divided as follows: 20% of from Yelp, 14% from WolframAlpha, 4% from Yahoo and 2% from Wikipedia.
"Breaking down Siri's reliance further," Munster writes, "Google provides 100% of navigation results, 61% of information results, 48% of commerce results and 42% of local results. Among other result aggregators, Yelp provided the most local results (51%) and commerce results (51%), while WolframAlpha provided 34% of information results."
