Drawing search device, drawing database construction device, drawing search system, drawing search method, and recording medium

A drawing database construction device comprising:

• a construction title field specification unit that specifies a type of a title field existing in drawing data for database construction;
• a construction arrangement specification unit that specifies arrangement of a plurality of boxes existing in the title field on a basis of the type of the title field specified by the construction title field specification unit;
• a construction recognition unit that executes a character recognition process on each character string existing at each position in a title field existing in the drawing data;
• a construction attribute specification unit that specifies an attribute value of the drawing data represented by a character string in the box and specifies an attribute associated with the box in advance on a basis of a character recognition result by the construction recognition unit and the arrangement of the plurality of boxes specified by the construction arrangement specification unit;
• and
• a construction unit that constructs a database by storing a combination of the attribute value specified by the construction attribute specification unit, the attribute, and the drawing data in the database.

A drawing search method for causing a computer to execute processing of:

• specifying a type of a title field existing in target drawing data;
• specifying an arrangement of a plurality of boxes existing in the title field on a basis of the specified type of the title field;
• executing character recognition processing on each character string existing at each position in the title field existing in the target drawing data;
• specifying a target attribute value representing an attribute value of the target drawing data represented by a character string in the box and specifying a target attribute that is an attribute associated with the box in advance on a basis of a character recognition result and the specified arrangement of the plurality of boxes;
• and
• searching for drawing data having an attribute value similar to the attribute value of the target drawing data from a database in which the drawing data, the attribute value of the drawing data, and the attribute corresponding to the attribute value are associated with each other on a basis of the specified combination of the target attribute value and the target attribute, and outputting a search result.

A recording medium for recording a program for causing a computer to execute processing of:

• specifying a type of a title field existing in target drawing data;
• specifying an arrangement of a plurality of boxes existing in the title field on a basis of the specified type of the title field;
• executing character recognition processing on each character string existing at each position in the title field existing in the target drawing data;
• specifying a target attribute value representing an attribute value of the target drawing data represented by a character string in the box and specifying a target attribute that is an attribute associated with the box in advance on a basis of a character recognition result and the specified arrangement of the plurality of boxes;
• and
• searching for drawing data having an attribute value similar to the attribute value of the target drawing data from a database in which the drawing data, the attribute value of the drawing data, and the attribute corresponding to the attribute value are associated with each other on a basis of the specified combination of the target attribute value and the target attribute, and outputting a search result.
