Data processing apparatus, data processing method, and non-transitory storage medium

Abstract

A data processing apparatus ( 1 ) of the present invention includes a unit that retrieves a predetermined subject from moving image data. The data processing apparatus includes a person extraction unit ( 10 ) that analyzes moving image data to be analyzed and extracts a person whose appearance frequency in the moving image data to be analyzed satisfies a predetermined condition among persons detected in the moving image data to be analyzed, and an output unit ( 20 ) that outputs information regarding the extracted person.

1 . A data processing apparatus comprising:
 at least one memory storing instructions; and   at least one processor configured to execute the instructions to perform:
 detecting multiple word strings from text data; 
 grouping the word strings using similarities of the word strings to generate multiple groups of the word strings; 
 extracting a group of the word strings whose appearance frequency in the text data satisfies a predetermined condition from the multiple groups of the word strings; and 
 outputting information regarding the extracted group. 
   
     
     
         2 . The data processing apparatus according to  claim 1 , wherein
 the at least one processor is further configured to perform:   outputting the appearance frequency together with the information regarding the extracted group.   
     
     
         3 . The data processing apparatus according to  claim 1 , wherein
 the at least one processor is further configured to perform:
 generating a graph showing a change of the appearance frequency of the word strings. 
   
     
     
         4 . The data processing apparatus according to  claim 1 , wherein
 the at least one processor is further configured to perform:
 outputting information indicating presence or absence of the word strings in the text data. 
   
     
     
         5 . The data processing apparatus according to  claim 1 , wherein
 the at least one processor is further configured to perform:
 acquiring the text data from one or more servers. 
   
     
     
         6 . A data processing method comprising:
 detecting multiple word strings from text data;   grouping the word strings using similarities of the word strings to generate multiple groups of the word strings;
 extracting a group of the word strings whose appearance frequency in the text data satisfies a predetermined condition from multiple groups of the word strings; and 
 outputting information regarding the extracted group. 
   
     
     
         7 . The data processing method according to  claim 6 , comprising:
 outputting the appearance frequency together with the information regarding the extracted group.   
     
     
         8 . The data processing method according to  claim 6 , comprising:
 generating a graph showing a change of the appearance frequency of the word strings.   
     
     
         9 . The data processing method according to  claim 6 , comprising:
 outputting information indicating presence or absence of the word strings in the text data.   
     
     
         10 . The data processing method according to  claim 6 , comprising:
 acquiring the text data from one or more servers.   
     
     
         11 . A non-transitory storage medium storing a program causing a computer to perform:
 detecting multiple word strings from text data;   grouping the word strings using similarities of the word strings to generate multiple groups of the word strings;   extracting a group of the word strings whose appearance frequency in the text data satisfies a predetermined condition from multiple groups of the word strings; and   outputting information regarding the extracted group.   
     
     
         12 . The non-transitory storage medium according to  claim 11 , wherein
 the program causes the computer to perform:   outputting the appearance frequency together with the information regarding the extracted group.   
     
     
         13 . The data processing method according to  claim 11 , wherein
 the program causes the computer to perform:
 generating a graph showing a change of the appearance frequency of the word strings. 
   
     
     
         14 . The data processing method according to  claim 11 , wherein
 the program causes the computer to perform:
 outputting information indicating presence or absence of the word strings in the text data. 
   
     
     
         15 . The data processing method according to  claim 11 , wherein
 the program causes the computer to perform:
 acquiring the text data from one or more servers.
