Information processing apparatus, control method, and program

Abstract

An information processing apparatus (2000) determines whether a content (30-1) of a relevant account (20-1) associated with a target account (10-1) and a content (30-2) of a relevant account (20-2) associated with a target account (10-2) are similar. When the content (30-1) and the content (30-2) are similar, the information processing apparatus (2000) executes predetermined processing related to the target account (10-1) and the target account (10-2).

1 . An information processing apparatus, comprising:
 a determination unit that determines, for a first relevant account associated with a first target account and a second relevant account associated with a second target account, whether first content data associated with the first relevant account and second content data associated with the second relevant account are similar; and   a processing execution unit that executes predetermined processing when it is determined that the first content data and the second content data are similar.   
     
     
         2 . The information processing apparatus according to  claim 1 ,
 wherein the determination unit determines whether the first content data and the second content data are similar by determining whether a distribution of a frequency of appearance of an object included in image data associated with the first relevant account and a distribution of a frequency of appearance of an object included in image data associated with the second relevant account are similar.   
     
     
         3 . The information processing apparatus according to  claim 1 ,
 wherein the determination unit determines whether the first content data and the second content data are similar by determining whether a distribution of a frequency of appearance of a word included in text data or voice data associated with the first relevant account and a distribution of a frequency of appearance of a word included in text data or voice data associated with the second relevant account are similar.   
     
     
         4 . The information processing apparatus according to  claim 1 ,
 wherein the determination unit determines whether the first content data and the second content data are similar by determining whether a distribution of a frequency of appearance of a speaker extracted from voice data associated with the first relevant account and a distribution of a frequency of appearance of a speaker extracted from voice data associated with the second relevant account are similar.   
     
     
         5 . The information processing apparatus according to  claim 1 ,
 wherein the determination unit determines whether the first content data and the second content data are similar by determining whether a distribution of a frequency of appearance of a topic extracted from content data associated with the first relevant account and a distribution of a frequency of appearance of a topic extracted from content data associated with the second relevant account are similar.   
     
     
         6 . The information processing apparatus according to  claim 1 ,
 wherein, as the predetermined processing, the processing execution unit outputs information indicating that there is a high probability that the first target account and the second target account are owned by a same person, or information indicating that there is a high probability that an owner of the first target account and an owner of the second target account belong to a same group.   
     
     
         7 . The information processing apparatus according to  claim 2 ,
 wherein, as the predetermined processing, the processing execution unit outputs the distributions generated by the determination unit.   
     
     
         8 . The information processing apparatus according to  claim 1 ,
 wherein, as the predetermined processing, the processing execution unit outputs content data that coincide or are similar among the first content data and the second content data.   
     
     
         9 . The information processing apparatus according to  claim 8 ,
 wherein the processing execution unit extracts an image region representing a characteristic part of a person included in image data and outputs the extracted image region.   
     
     
         10 . The information processing apparatus according to  claim 8 ,
 wherein the processing execution unit outputs information indicating at least one of a type, a maker, and a number of a number plate of a vehicle included in image data.   
     
     
         11 . The information processing apparatus according to  claim 8 ,
 wherein the processing execution unit outputs a name or a location of a landmark included in image data.   
     
     
         12 . A control method executed by a computer, comprising:
 a determination step of determining, for a first relevant account associated with a first target account and a second relevant account associated with a second target account, whether first content data associated with the first relevant account and second content data associated with the second relevant account are similar; and   a processing execution step of executing predetermined processing when it is determined that the first content data and the second content data are similar.   
     
     
         13 - 22 . (canceled) 
     
     
         23 . A non-transitory computer readable medium storing a program causing a computer to execute each step of a control method, the method comprising:
 a determination step of determining, for a first relevant account associated with a first target account and a second relevant account associated with a second target account, whether first content data associated with the first relevant account and second content data associated with the second relevant account are similar; and   a processing execution step of executing predetermined processing when it is determined that the first content data and the second content data are similar.   
     
     
         24 . The information processing apparatus according to  claim 3 ,
 wherein, as the predetermined processing, the processing execution unit outputs the distributions generated by the determination unit.   
     
     
         25 . The information processing apparatus according to  claim 4 ,
 wherein, as the predetermined processing, the processing execution unit outputs the distributions generated by the determination unit.   
     
     
         26 . The information processing apparatus according to  claim 5 ,
 wherein, as the predetermined processing, the processing execution unit outputs the distributions generated by the determination unit.
