Method and device for extracting chart information in file

An electronic device for extracting chart information in a file, comprising:

• a processor;
• memory;
• and
• a plurality of computer instructions stored in the memory, wherein the computer instructions, when executed by the processor, cause the electronic device to perform operations including:
• inputting, by the electronic device, a file which includes a to-be-identified page;
• parsing, by the electronic device, an underlying data stored in the to-be-identified page, and combining the underlying data into a data block according to a behavior identifier in the underlying data;
• extracting, by the electronic device, a graphic object and a word object from the data block respectively, and obtaining location information of the word object and of the graphic object in the to-be-identified page;
• identifying, by the electronic device, a chart area in the to-be-identified page according to the graphic object and the word object;
• and
• performing, by the electronic device, data fusion on the word object and the graphic object in the chart area to obtain the chart information contained in the chart area, wherein the chart information comprising one or more of a title, a legend, a scale, and a scale attribute.

A non-transitory computer readable storage medium comprising computer readable instructions that, when executed by a processor of an electronic device, cause the electronic device to perform operations including:

• inputting, by the electronic device, a file which includes a to-be-identified page;
• parsing, by the electronic device, an underlying data stored in the to-be-identified page, and combining the underlying data into a data block according to a behavior identifier in the underlying data;
• extracting, by the electronic device, a graphic object and a word object from the data block respectively, and obtaining location information of the word object and of the graphic object in the to-be-identified page;
• identifying, by the electronic device, a chart area in the to-be-identified page according to the graphic object and the word object;
• and
• performing, by the electronic device, data fusion on the word object and the graphic object in the chart area to obtain the chart information contained in the chart area, wherein the chart information comprising one or more of a title, a legend, a scale, and a scale attribute.
