Related-word registration device, information processing device, related-word registration method, program for related-word registration device, recording medium, and related-word registration system

A related-word registration device comprising:

• a search query obtaining means that obtains a search query including a search word entered by the user;
• a search query storing means that stores the obtained search query in association with user identification information and acquisition time of the search query;
• a search query extracting means, in the case where a predetermined user operation is detected, that extracts search queries corresponding to the user identification information of the user;
• a first search query specifying means that specifies a first search query from the extracted search queries;
• a second search query specifying means that specifies, as a second search query, a search query different from the first search query from the extracted search queries;
• and
• a related-word registering means that registers, as related words, a search word in the first search query and a search word in the second search query into a related-word database.

A related-word registration method of a related-word registration device for registering related words, comprising:

• a search query obtaining step of obtaining a search query including a search word entered by the user;
• a search query storing step of storing the obtained search query in association with user identification information and acquisition time of the search query;
• a search query extracting step, in the case where a predetermined user operation is detected, of extracting search queries corresponding to the user identification information of the user;
• a first search query specifying step of specifying a first search query from the extracted search queries;
• a second search query specifying step of specifying a second search query whose acquisition time is earlier than acquisition time of the first search query, from the extracted search queries;
• and
• a related-word registering step of registering, as related words, a search word in the first search query and a search word in the second search query into a related-word database.

A program for a related-word registration device, for making a computer function as:

• a search query obtaining means that obtains a search query including a search word entered by the user;
• a search query storing means that stores the obtained search query in association with user identification information and acquisition time of the search query;
• a search query extracting means, in the case where a predetermined user operation is detected, that extracts search queries corresponding to the user identification information of the user;
• a first search query specifying means that specifies a first search query from the extracted search queries;
• a second search query specifying means that specifies a second search query whose acquisition time is earlier than acquisition time of the first search query, from the extracted search queries;
• and
• a related-word registering means that registers, as related words, a search word in the first search query and a search word in the second search query into a related-word database.

A computer-readable recording medium which stores a program for a related-word registration device, for making a computer function as:

• a search query obtaining means that obtains a search query including a search word entered by the user;
• a search query storing means that stores the obtained search query in association with user identification information and acquisition time of the search query;
• a search query extracting means, in the case where a predetermined user operation is detected, that extracts search queries corresponding to the user identification information of the user;
• a first search query specifying means that specifies a first search query from the extracted search queries;
• a second search query specifying means that specifies a second search query whose acquisition time is earlier than acquisition time of the first search query, from the extracted search queries;
• and
• a related-word registering means that registers, as related words, a search word in the first search query and a search word in the second search query into a related-word database.

A related-word registration system having a terminal, a related-word registration device which is connected to the terminal via a network, and receives a related word from the terminal, and a related-word database which registers the related word, wherein the terminal comprises:

• a search query obtaining means that obtains a search query including a search word entered by the user;
• a search query storing means that stores the obtained search query in association with user identification information and acquisition time of the search query;
• a search query extracting means, in the case where a predetermined user operation is detected, that extracts search queries corresponding to the user identification information of the user;
• a first search query specifying means that specifies a first search query from the extracted search queries;
• a second search query specifying means that specifies a second search query whose acquisition time is earlier than acquisition time of the first search query, from the extracted search queries;
• and
• a related-word transmitting means that transmits, as related words for registration, a search word in the first search query and a search word in the second search query to the related-word registration device, and
• the related-word registration device comprises related-word registering means that registers, as related words, the search word in the first search query and the search word in the second search query received into the related-word database.
