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 computer program product for keyword searching, the computer program product comprising:

a non-transitory computer readable storage medium and program instructions stored on the non-transitory computer readable storage medium, the program instructions comprising;

program instructions to collect 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;

program instructions to store the collected user information associated with the keyword search in a memory;

program instructions to receive an indication of a search of content for at least one keyword;

program instructions to determine whether the at least one keyword is associated with the collected user information associated with the keyword search in the memory; and

program instructions to, responsive to determining that the at least one keyword is associated with the collected user information associated with the keyword search in the memory, calculate a rank for the at least one keyword.

2. The computer program product of claim 1, further comprising:

program instructions to, 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, search a hard disk for information associated with the at least one keyword.

3. The computer program product of claim 1, further comprising:

program instructions to write the stored collected user information associated with the keyword search in the memory to a hard disk at a predetermined time interval.

4. The computer program product of claim 1, further comprising:

program instruction to update the collected user information associated with the keyword search in the memory, based on a user search request.

5. The computer program product of claim 1, wherein the program instructions to calculate a rank for the least one keyword comprise:

program instructions to determine a life cycle for each of;

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

program instructions to adjust a ratio for each of the object search, the holding time, and the selecting time.

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

7. The computer program product 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.

8. A computer system for keyword searching, the computer system comprising:

one or more computer processors;

one or more computer readable storage media; and

program instructions stored on the one or more computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising;

program instructions to collect 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;

program instructions to store the collected user information associated with the keyword search in a memory;

program instructions to receive an indication of a search of content for at least one keyword;

program instructions to determine whether the at least one keyword is associated with the collected user information associated with the keyword search in the memory; and

program instructions to, responsive to determining that the at least one keyword is associated with the collected user information associated with the keyword search in the memory, calculate a rank for the at least one keyword.

9. The computer system of claim 8, further comprising:

program instructions to, 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, search a hard disk for information associated with the at least one keyword.

10. The computer system of claim 8, further comprising:

program instructions to write the stored collected user information associated with the keyword search in the memory to a hard disk at a predetermined time interval.

11. The computer system of claim 8, further comprising:

program instruction to update the collected user information associated with the keyword search in the memory, based on a user search request.

12. The computer system of claim 8, wherein the program instructions to calculate a rank for the least one keyword comprise:

program instructions to determine a life cycle for each of;

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

program instructions to adjust a ratio for each of the object search, the holding time, and the selecting time.

13. The computer system of claim 8, wherein the object search information comprises information associated with a user stopping at a keyword within a document.

14. The computer system of claim 8, wherein the holding time information comprises information associated with a time spent by a user reading a certain part of a document.
