Facebook's Graph Search has been met with mixed reviews from within the tech community, with my personal experience not being that exciting. Today Google announced major improvements into its graph search competitor Knowledge Graph, which it launched a year ago.
Google says that "The search of the future will need to answer, converse, and anticipate." At today's I/O keynote, Google announced that you'll start to get important statistics, provided by the knowledge graph. Right now, you can search for the population of India; beginning today, it will anticipate what you're likely to ask next: what's the population compared to other countries? Today, Knowledge Graph is also launching in new languages: Polish, Turkish, Simplified Chinese and Traditional Chinese.
Google also has taken a stab at Apple by launching its Siri-like Voice Search into the web. Now you can simply sit back in your chair and speak into your microphone and Google will return an audible response to your question. No need to press a button or anything. Simply say "OK Google", and state your question. Conversational voice search will be available across all platforms with Chrome.
