1. An information processing device comprising:
a hardware processor configured to:
acquire document data;
perform morphological analysis of the acquired document data, the morphological analysis comprising extracting, from the acquired document data, a plurality of morphemes included in the document data, each of the plurality of morphemes being a minimum linguistically meaningful unit of a sentence;
determine a feature representing the acquired document data based on a result of the morphological analysis and of applying a hash function, the feature comprising an array of values each obtained for a respective one of the plurality of morphemes;
output export data, to a second information processing device, that is data converted based on the determined feature;
acquire a result of first processing performed by the second information processing device based on the export data; and
perform second processing based on the result of the first processing acquired by the hardware processor,
wherein the export data comprises the feature and a search parameter generated based on the feature,
wherein the second information processing device generates a learned model through machine learning based on the feature and uses the learned model to perform the first processing, and
wherein the hardware processer is configured to acquire, as the result of the first processing, data included in the learned model that is output and satisfying a condition indicated by the search parameter.
