Information processing apparatus and information processing method

An information processing apparatus storing an index including one or more data items with each of which a vectorized unstructured data item and one or more structured data items are associated,

• a processor of the information processing apparatus:
• receiving an input including a query vector that gives a condition that the vectorized unstructured data item should satisfy and a search condition that gives a condition that the one or more structured data items should satisfy;
• calculating a first scale representing closeness between the query vector and the vectorized unstructured data item associated with one of one or more data items in the index that are the one or more data items included in the index;
• calculating a second scale representing closeness between the search condition and the one or more structured data items associated with the data item in the index;
• calculating a second evaluation indicator representing closeness between the first scale and the second scale;
• and
• extracting one or more of the one or more data items in the index satisfying the query vector and the search condition according to the second evaluation indicator.

An information processing method executed by an information processing apparatus storing an index including one or more data items with each of which a vectorized unstructured data item and one or more structured data items are associated, the information processing method comprising processes of
