Abstract

According to one embodiment, a record information storage module stores record information related to content recorded by an external apparatus in association with a keyword representing the content and user information. A search information storage module stores a search phrase used for searching in an external apparatus in association with user information. A search word handler extracts a predetermined number of words having high search frequency from search phrases stored in association with specific user information to generate a word list. A record information handler extracts keywords stored in association with the specific user information to generate a keyword list. A ranking processor generates ranking information indicating a word in the word list which matches a keyword in the keyword list. A communicator provides the ranking information to an external apparatus corresponding to the specific user information.

Claims

1-8. -8. (canceled)

9.

a record information storage module configured to store a keyword representing content recorded on the first apparatus in association with user information identifying a user who instructs to record the content;

a search information storage module configured to store a search phrase used for search by the second apparatus in association with user information identifying a user who instructs the search;

a search word handler configured to extract a predetermined number of words having high search frequency from search phrases stored in the search information storage module in association with user information identifying a specific user to generate a word list;

a record information handler configured to extract keywords stored in association with the user information identifying the specific user from the record information storage module to generate a keyword list;

a ranking processor configured to generate ranking information indicating a word in the word list which matches a keyword in the keyword list; and

an information provider configured to provide the ranking information to the first apparatus or the second apparatus, and display record information of content, among contents stored in the first apparatus, associated with a keyword corresponding to a word contained in the ranking information.

10. The information providing server of claim 9, further comprising a receiver configured to receive from the first apparatus or the second apparatus a request for the ranking information including at least the user information identifying the specific user, wherein

the search word handler is configured to extract the predetermined number of words having high search frequency from the search phrases stored in association with the user information included in the request, and

the record information handler is configured to extract the keywords stored in association with the user information included in the request.

11. The information providing server of claim 9, further comprising a language analyzer configured to divide the search phrase into words, wherein

the search information storage module is configured to store the search phrase as the words.

12. The information providing server of claim 9, wherein

the search information storage module is configured to store search date at which searching is performed in association with a corresponding search phrase and user information, and

the search word handler is configured to generate the word list in which the words are listed in descending order of search frequency and the search date.

13. The information providing server of claim 9, wherein the search word handler is configured to generate the word list in which a word indicating a proper noun is placed at higher order.
