Data processing system, data processing method, and data structure

A data processing method for a data processing system accessing a database and executing data processing, comprising:

• a processor for executing a program and a storage device for storing the program, wherein the database has a data structure comprising:
• a data source field;
• an extraction target data field storing extraction target data of natural language from a data source specified in the data source field;
• and
• a search target data field storing search target data that is associated with the extraction target data and that can be interpreted in the data processing, wherein
• the search target data includes first attribute information which is a character string of natural language indicating an attribute of the extraction target data;
• annotation information obtained by associating a noun phrase of natural language indicating an annotation related to the extraction target data;
• and
• second attribute information which is a character string of natural language indicating an attribute of the annotation, wherein
• the first attribute information is searched with a search character string specific to the data processing when an input character string is given, and
• the annotation information is searched based on the input character string to the data processing when the input character string is given, wherein
• in the data processing method, the processor executes extraction processing for extracting specific first attribute information of specific search target data related to the data processing and specific extraction target data corresponding to the specific search target data, and
• output processing for outputting an extraction result with the extraction processing.

A non-transitory computer-readable medium comprising a data structure searched when data processing is executed, the data structure comprising:

• a data source field;
• an extraction target data field storing extraction target data of natural language from a data source;
• and
• a search target data field storing a search target data that is associated with the extraction target data and that can be interpreted in the data processing, wherein the search target data comprises:
• first attribute information which is a character string of natural language indicating an attribute of the extraction target data;
• annotation information obtained by associating a noun phrase of natural language indicating an annotation related to the extraction target data;
• and
• second attribute information which is a character string of natural language indicating an attribute of the annotation, wherein
• the first attribute information is searched with a search character string specific to the data processing when an input character string is given, and
• the annotation information is searched based on the input character string the data processing when the input character string is given.
