1. A method to display inferences according to evaluated inference strength, comprising: receiving, by a computing device, streaming audio or video data; converting, by the computing device, voice within received audio or video data to streaming text; performing a web search using two or more words within the streaming text as search terms to determine topical relatedness of the two or more words within the streaming text; when topical relatedness of the two or more words within the streaming text is above a predetermined relatedness threshold, automatically combining, by the computing device, the two or more words within the streaming text with one or more neighboring words within the streaming text to create a larger word combination, and automatically performing a web search using the larger word combination as search terms to determine topical relatedness of the larger word combination; and when topical relatedness of the two or more words or the larger word combination within the streaming text is below the predetermined relatedness threshold: automatically performing at least one web search using the two or more words or the larger word combination within the streaming text to identify, by the computing device, at least one inference regarding subject matter of the streaming text; determining, by the computing device, a strength of the at least one inference; and displaying the at least one inference by the computing device, along with the streaming text, when the strength of the at least one inference is above a predetermined strength threshold, or displaying the at least one inference by the computing device, along with the streaming text, when the strength of the at least one inference is greater than a strength of one or more other inferences identified by the computing device.
