解説
問 23
Incorrectア
VR (Virtual Reality) is a technology that lets people experience computer-generated images or spaces as if they were real. It is used for immersive experiences in games and training simulations, but it is not a technology that improves the shogi software’s move-judging ability, so it is wrong.
Incorrectイ
ER (Entity Relationship) refers to concepts such as the ER diagram, which expresses the relationships among data using “entities” and “relationships” in database design. It is a technique for organizing data structures, not the core technology behind the shogi software’s improvement, so it is wrong.
Incorrectウ
EC (Electronic Commerce) is a mechanism for buying and selling goods or services over the internet, such as online shopping. It is a form of business transaction and is not a technology related to the shogi software’s thinking ability, so it is wrong.
- エ
正解 The correct answer is “エ: AI”. AI (Artificial Intelligence) is a general term for technologies that let a computer perform human-like reasoning and learning; through machine learning and deep learning it can learn patterns and evaluation functions from huge amounts of game-record data. Shogi software combines this learning ability of AI with high-speed search of board positions, raising the accuracy of its move evaluation to the point of being able to beat professional players. The technology at the core of the capability improvement that the question asks about is exactly AI, so エ is the most appropriate.
ここがポイント
- AI (Artificial Intelligence) can learn patterns and evaluation criteria from large amounts of data through machine learning and deep learning; it is the core technology that made shogi and go software strong enough to beat professionals.
- Distinguish the confusable abbreviations: VR = virtual reality, ER = entity relationship (database design), EC = electronic commerce — each has a completely different purpose.
