Specifically, the system control unit 14 of the response determination server 10 performs character conversion on a word included in a question sentence or the like as an example of character conversion means, and generates a character conversion word. For example, the system control unit 14 of the response determination server 10 replaces “n” and “yo” in “Nenshoushi” to generate a character conversion word “Nenoshiushi” and “bakuhatsu”. “Ha” and “tsu” in are replaced with each other to generate a character conversion word “defeated”.
- system control unit 14 of the response determination server 10 replaces “small” “a” and “l” to generate a character conversion word “smlal”, and “i” and “a” in “container”. And the character conversion word “contianer” is generated.
- the phrase “Nenshoshi” may be treated as a word.
- the system control unit 14 of the response determination server 10 generates a character conversion question by exchanging the acquired word and the character conversion word in the question text as an example of the character conversion question generation unit.
- the system control unit 14 of the response determination server 10 converts the word “Nenshoshi” into the character conversion word “Nenoshiushi” for the question sentence “Nenshoshi Bakuhatsuru Fumatsutsu ...”. And replace the word “Bakuhatsuru” with the character conversion word “Bakuhatsuhuru”, and so on. Generate text for transliteration questions.
- the system control unit 14 of the response determination server 10 replaces the word “small” with the character conversion word “smlal” for the question sentence “A small container filled with powder that burns ...” Processing such as replacing “container” with the character conversion word “contianer” is performed to generate a sentence of a character conversion question “A smlal contianer fliled with pwoder taht bruns... Thus, the system control unit 14 of the response determination server 10 generates a character conversion question corresponding to the question using the converted character conversion word.
- the response determination server 10 stores the correct answer, question, and character conversion question in the verification DB 12a (step S16). Specifically, the system control unit 14 of the response determination server 10 assigns a question code to each question as an example of a question storage unit or a correct answer storage unit, and the correct answer is stored in the table of the verification DB 12a as shown in FIG. , Questions, and transliteration questions. In addition to the inputted correct answer “fireworks”, the system control unit 14 of the response determination server 10 includes “Hanabi”, “Smoke”, “Hanabi”, “hanabi”, “firework”, “FIREWORK”, “fireworks”, etc. May also be stored in the verification DB 12a.
- a category code is assigned in advance for each category such as science, literature, history, etc., and the system control unit 14 of the response determination server 10 determines the category code from the category to which the correct term belongs.
- the category to which the correct term belongs may be acquired from the dictionary DB 8 when searching, or may be determined from a category dictionary that the storage unit 12 has in advance.
- the system control unit 14 of the response determination server 10 may determine the difficulty level of the question based on the length of the question text or the category, and for each user based on the user information in the member DB 22b. You may decide to. Further, the system control unit 14 of the response determination server 10 may generate a hint from a category name or the like.
- the response determination server 10 may omit step S15 and generate a character conversion question, and leave the character conversion question portion blank in the table of the collation DB 12a. .
- the response determination server 10 acquires a question composed of text information (step S5). Specifically, the system control unit 14 of the response determination server 10 accepts input of words such as “Apple” and “apple” and sentences as questions from an input unit (not shown) as an example of a question / correct answer acquisition unit. A question such as a word or a sentence stored in advance in the storage unit 12 or the like as an example of a question storage unit that stores a question including text information is read out. The system control unit 14 of the response determination server 10 functions as an example of a question / correct answer acquisition unit that acquires a question and a correct answer to the question by acquiring the question.
- the response determination server 10 performs a search using the question as a search keyword (step S6). Specifically, the system control unit 14 of the response determination server 10 generates a search query using a search keyword such as “Apple” or “apple” of the question as a search keyword, and sends it to the data search server 7 through the communication unit 11. Send.
- the data search server 7 performs a search with reference to the dictionary DB 8 and transmits a search result for the search keyword to the response determination server 10.
- the response determination server 10 may search by adding other keywords, such as “Apple association”.
- the response determination server 10 acquires a search result (step S7). Specifically, the system control unit 14 of the response determination server 10 and the system control unit 14 of the response determination server 10 receive the search result for the search keyword from the data search server 7.
- a search result for “apple” or “apple” a search result including a synonym, an associative word, a translated word, or a sentence of definition or explanation is acquired. For example, “red”, “round”, “apple”, etc. for “apple”, “red”, “round”, “pomme”, etc. are obtained for “apple”.
- the category information is also acquired.
- the response determination server 10 generates a correct answer from the search result (step S8). Specifically, the system control unit 14 of the response determination server 10 extracts a word from the search result as an example of a question / correct answer generation unit and sets it as a correct answer.
- the system control unit 14 of the response determination server 10 for example, “red”, “round”, “apple”, etc. for “apple”, “red”, “round”, “pomme” for “apple”. Etc. are correct.
- the system control unit 14 of the response determination server 10 functions as an example of a question / correct answer acquisition unit that acquires a question including text information and a correct answer to the question by generating a correct answer from the search result.
