Information processing apparatus, information processing system, information processing method, and non-transitory recording medium

An information processing system comprising:

• circuitry configured to:
• receive a request from a user which designates an expert as an information type of a collection target and a character string related to the collection target;
• convert the character string to a first vector represented by distributed representation that is an expression according to a meaning contained in data to be converted;
• convert a plurality of items of document data to second vectors represented by the distributed representation, respectively, the plurality of items of document data stored in one or more memories as target data including document data created or updated by a person;
• calculate a similarity between the first vector and the second vectors for each of the plurality of items of document data;
• extract the second vector with a similarity that satisfies a predetermined requirement;
• acquire an item, corresponding to the second vector extracted, among the plurality of items of document data;
• collect identification information of the person who created or updated the item acquired as corresponding to the second vector extracted;
• and
• generate display information, the display information causing a display to display a list including the identification information of the person.
