1. An information providing system, comprising:
a meta-ID estimation processing database that is built on machine learning, using a data structure for machine learning, which includes a plurality of items of training data that each include evaluation target information including image data, and a plurality of meta-IDs respectively linked with the evaluation target information via a degree of meta association, wherein the image data included in the evaluation target information includes an image showing (i) the specific device and (ii) the specific identification label for identifying the specific device:
a reference database that stores a plurality of content IDs linked with the meta-IDs, and a plurality of items of reference information corresponding to the content IDs;
a content association database storing (i) a plurality of pieces of external information, the plurality of pieces of external information comprising content which is divided in a chunk structure, and (ii) a plurality of pieces of chunk reference information, in which reference information having a different attribute than the content is divided in a chunk structure, wherein the content association database stores the plurality of pieces of external information in association with the plurality of pieces of chunk reference information, the plurality of pieces of external information corresponding to the plurality of pieces of chunk reference information on a one-to-one basis, wherein the external information includes text information, the chunk reference information includes text information, and the external information is a chunk structure of a source of the reference information;
an external information similarity calculation database built on machine learning using the plurality of pieces of external information; and
a hardware processor that is configured to:
acquire input information including first image data including text information;
look up the meta-ID estimation processing database and select a first meta-ID, among the plurality of meta-IDs, based on the acquired input information;
look up the reference database and select a first content ID from among a plurality of the content IDs which are linked with the first meta-ID;
look up the reference database and select first reference information, among the plurality of items of reference information, based on the first content ID;
acquire specific external information, wherein the specific external information includes text information;
compare the external information stored in the content association database with the acquired specific external information, and judge whether or not the external information stored in the content association database matches with the acquired specific external information;
in a case in which it is judged that the external information stored in the content association database does not match with the acquired specific external information, look up the external information similarity calculation database, and calculate an external information similarity, which is a similarity between the external information and the acquired specific external information, wherein calculating the external information similarity comprises vectorizing the specific external information and calculating the external information similarity between the specific external information and the external information based on the vectorized external information and vector operations in the external information similarity calculation database; and
select first external information from the plurality of pieces of external information, based on the external information similarity, look up the content association database, and extract the chunk reference information associated with the first external information as first chunk reference information,
wherein in a case in which it is judged that the external information stored in the content association database matches with the acquired specific external information, the hardware processor does not calculate the external information similarity.
