Even when there are many candidates for a linked entity, accuracy of estimating an entity related to a term that appears on given writing is improved. A classification device stores a first model generated by using a corpus including pieces of first writing related to predetermined entities, and a second model generated by using a corpus including the pieces of first writing. Features of terms included in the first writing are acquired from the first model. Features of the pieces of first writing are acquired from the second model. The classification device causes the first model to output first information indicating entities indicated by terms, which has similarity in a feature to a second term included in second writing, among first terms indicating the predetermined entities. The classification device causes the second model to output second information indicating entities related to pieces of writing, which has similarity in a feature to the second writing, among the pieces of first writing. The classification device determines linking of the second term based on the first information and the second information.

To reduce time and labor in identifying a similar category among a plurality of categories into which objects are classified. Based on a predetermined operation performed by a user with respect to two objects among a plurality of objects classified into some of a plurality of predetermined categories, the information processing system deduces the two objects as comparison targets. Then, based on the number of times at which the two objects are deduced as comparison targets, the information processing system determines two categories into which the two objects are respectively classified as similar categories.
