ENCODING DEVICE AND ENCODING METHOD

An information processing apparatus (100) identifies a plurality of tag sections and a plurality of original text sections in input character data that includes a tag having a variable section. The information processing apparatus (100) converts each of a plurality of tags included in the plurality of tag sections into a plurality of first-type codes that respectively corresponds to tag contents of the plurality of tags. The information processing apparatus (100) converts original texts in the plurality of original text sections into a plurality of second-type codes. The information processing apparatus (100) outputs an encoded data including the plurality of first-type codes and the plurality of second-type codes, positional relationships of the plurality of tags and the original texts in the input character data being maintained with corresponding plurality of first-type codes and corresponding plurality of second-type codes in the encoded data.
