Abstract

Embodiments of the present invention provide efficient systems and methods for searching a keyword. Embodiments of the present invention can be used to more quickly and comprehensively search a document for a keyword or phrase, based on the preferences and behaviors of a user, so that the returned results to the user are ranked in order of the preferences of the user. By factoring in user data such as time spent on certain content and highlighted content, the system is able to more efficiently return preferred results of a user of a keyword search.

Claims

1. A method for keyword searching, the method comprising:

collecting, by one or more computer processors, user information associated with a keyword search, wherein the user information comprises object search information, holding time information, and selecting time information, wherein the selecting time information comprises information associated with a section of a document highlighted by a user when viewing the document;

storing, by one or more computer processors, the collected user information associated with the keyword search in a memory;

receiving, by one or more computer processors, an indication of a search of content for at least one keyword;

determining, by one or more computer processors, whether the at least one keyword is associated with the collected user information associated with the keyword search in the memory; and

responsive to determining that the at least one keyword is associated with the collected user information associated with the keyword search in the memory, calculating, by one or more computer processors, a rank for the at least one keyword.

2. The method of claim 1, further comprising:

responsive to determining that the at least one keyword is not associated with the collected user information associated with the keyword search in the memory, searching, by one or more computer processors, a hard disk for information associated with the at least one keyword.

3. The method of claim 1, further comprising:

writing, by one or more computer processors, the stored collected user information associated with the keyword search in the memory to a hard disk at a predetermined time interval.

4. The method of claim 1, further comprising:

updating, by one or more computer processors, the collected user information associated with the keyword search in the memory, based on a user search request.

5. The method of claim 1, wherein calculating a rank for the at least one keyword comprises:

determining, by one or more processors, a life cycle for each of;

an object search, a holding time, and a selecting time; and

adjusting, by one or more processors, a ratio for each of the object search, the holding time, and the selecting time.

6. The method of claim 1, wherein the object search information comprises information associated with a user stopping at a keyword within a document.

7. The method of claim 1, wherein the holding time information comprises information associated with a time spent by a user reading a certain part of a document.
