Abstract: A non-transitory computer-readable recording medium stores therein a generating program that causes a computer to execute a process including: receiving a word; generating a first and a second vectors according to the received word by applying a first and a second conversion parameters each to the received word; and generating a new third vector according to the word based on the generated first and second vectors.

Abstract: A non-transitory computer-readable recording medium having stored therein a learning program for causing a computer to execute a process includes: receiving a first sentence expressed in a first language and a second sentence obtained by translating the first sentence; and training a conversion parameters configured to convert each word of a received first sentence into a corresponding word of a received second sentence by utilizing machine learning.

Abstract: An apparatus acquires a plurality of text data items each including a question sentence and an answer sentence. The apparatus identifies a first word that exists in each of a plurality of question sentences included in the acquired plurality of text data items where a number of the plurality of question sentences satisfies a predetermined criterion, and identifies, from the plurality of question sentences, a second word that exists in a question sentence not including the first word and that does not exist in a question sentence including the first word. The apparatus classifies the plurality of text data items into a first group of text data items each including a question sentence in which the identified first word exists and a second group of text data items each including a question sentence in which the identified second word exists.

Abstract: A search apparatus includes a memory and a processor configured to receive question information, perform evaluation of the question information, and when a result of the evaluation satisfies a condition, output answer information extracted by searching based on the question information, the answer information being extracted from among a plurality of pieces of answer information stored in the memory, and, when the result of the evaluation does not satisfy the condition, output information for prompting input of additional information to specify detail of the question information.
