Abstract:
1. A method for tagging original data generated by things in the Internet of Things (IoT), comprising: identifying, by a computer, based on keyword searching, one or more social media messages on a network server related to an event of interest; filtering, by the computer, the identified one or more social media messages based on a message posting time occurring in a predefined time interval about the event of interest; filtering, by the computer, the time filtered social media messages based on message content describing an event that is occurring or has just occurred; extracting, by the computer, physical location information contained in the occurring-just-occurred filtered social media messages; identifying, by the computer, data generating devices that are within a predefined distance of the event of interest based on the extracted physical location information and the data generating devices' known locations; and tagging, by the computer, original data generated by the identified data generating devices with semantic metadata based on the predefined time interval about the event of interest and the content of the occurring-just-occurred filtered social media messages.
