An information processing apparatus () determines whether a content (-) of a relevant account (-) associated with a target account (-) and a content (-) of a relevant account (-) associated with a target account (-) are similar. When the content (-) and the content (-) are similar, the information processing apparatus () executes predetermined processing related to the target account (-) and the target account (-).

Information processing apparatus, control method, and program

In order to extract, with high accuracy, useful information from contribution information of social media, the present invention provides a processing apparatusincluding: an acquisition unitthat acquires contribution information relating to a target area; a computation unitthat computes a degree of reliability of the contribution information, based on at least two of an activity area of a contributor of the contribution information, a degree of reliability of an estimation result of the activity area, a degree of disclosure of a profile of the contributor, an attribute of the contributor, an attribute of the activity area for the contributor, and a category of a content of the contribution information; and an output unitthat outputs the contribution information in which a degree of reliability of the contribution information is higher than a threshold value.

Processing apparatus, processing method, and non-transitory storage medium

To reduce a decrease in search accuracy in a technique for comparing feature values acquired by collecting a local feature value by patch unit, the present invention provides an image processing apparatusincluding: an image processing unitthat detects an object region occupied by an object in an image; a patch size decision unitthat decides a patch size, based on a size of the object region; a patch unit feature value-computation unitthat sets a plurality of patches having the patch size described above in the object region, and computes a patch unit feature value acquired by collecting a local feature value in a patch for each patch; and a search unitthat searches for an image similar to a query image from among a plurality of reference images by using the patch unit feature value.

Image processing apparatus, image processing method, and non-transitory storage medium

An acquiring unit acquires information of the residence of one or more second users each having a second social media account related to a first user having a first social media account. An estimating unit estimates the residence of the first user from the information of the residence of the second user. A detecting unit detects a posting area at which the first user has posted on social media. A comparing unit compares the detected posting area with the estimated residence of the first user. A determining unit determines whether the posting area is an ordinary activity area or an extraordinary activity area for the first user based on the result of the comparison.

Posting location ordinariness/extraordinariness determination system

Provided is an estimating device, an estimating method, and an estimating program that each make it possible to estimate the area of activity of a target user with a smaller amount of information. An estimating device includes a first position distribution generating unit configured to generate a first position distribution of a target user on social media based on account information of the target user, a second position distribution generating unit configured to generate a second position distribution of a friend who is friends with the target user on the social media based on account information of the friend, and an estimating unit configured to estimate an area of activity of the target user based on the generated first position distribution and the generated second position distribution.

Estimating device, estimating method, and estimating program

An information processing apparatus capable of accurately specifying identification information whose users are the same user regardless of information registered by users is provided. The information processing apparatus may include at least one memory storing instructions and at least one processor configured to execute the instructions to: acquire positional information associated with at least one piece of related identification information related to each of a plurality of pieces of identification information for identifying users in a communication service; specify hierarchized positional information indicating positional information hierarchized in accordance with a granularity level of a position based on the positional information; calculate a similarity between pieces of identification information using the hierarchized positional information; and specify the pieces of identification information belonging to the same user from among the plurality of pieces of identification information based on the calculated similarity.
