1. A posted information extraction control device comprising:
at least one processor that is configured to:
acquire posted information that includes at least one of characters or an image and that has been submitted over a network and includes position information for a submission origin of the posted information;
perform natural language analysis on the acquired posted information to select first posted information from the posted information, the first posted information including character string information of a location character string indicating a position;
split the first posted information into individual words and determine respective parts of speech of the individual words using machine learning;
certify whether the first posted information is submitted from within a given area based on one or more tenses of the respective parts of speech of the individual words, wherein the given area is related to the position indicated by the character string information;
extract, as second posted information, a part of the first posted information that is certified as submitted within the given area and that includes selected information, which is selected as relating to a target present within the given area;
receive longitude-latitude information that has been generated from sensor data on a user device that is a submission origin of the posted information, the longitude-latitude information having been automatically embedded in the position information included in the posted information;
compare the longitude-latitude information with the character string information indicating the position and generating thereby a comparison result;
determine a credibility of the position, which is indicated by the character string information, based on the comparison result,
request a user to provide a response to a predetermined statement upon registration by the user,
analyze the response and classify the user into a category of a plurality of user categories; and
provide a social heat map including a density level of a subset of the selected information, which relates to the target present within the given area, that corresponds to the category into which the user was classified.
