Abstract

Receiving contextual data including a facial movement associated with an active document. A response associated with the active document is detected and associated with the received contextual data. A contextual metadata tag is generated based on the detected response to the active document. A contextual keyword is created that corresponds to the contextual metadata tag. Search results received in response to the query are filtered based on the contextual metadata tag.

Claims

1. A computer-implemented method for filtering document search results, the computer-implemented method comprising:

receiving contextual data comprising a facial movement associated with an active document;

detecting a response associated with the active document based on the received contextual data;

generating a contextual metadata tag based on the detected response to the active document;

receiving a query comprising a contextual keyword corresponding to the contextual metadata tag;

filtering search results received in response to the query based on the contextual metadata tag; and

displaying a list of the filtered search results.

2. The method of claim 1, wherein detecting the response comprises detecting the facial movement based on the contextual data, the contextual data further comprising a received image of a face of a user reading the active document.

3. The method of claim 1, wherein detecting the response comprises detecting an emotional response based on the contextual data.

4. The method of claim 1, comprising receiving, via a processor, contextual data comprising an image of a face of a user reading the active document.

5. The method of claim 1, comprising receiving, via the processor, contextual data comprising a location and a time associated with the active document.

6. The method of claim 1, wherein generating, via the processor, a contextual metadata tag comprises generating a mood tag corresponding to a mood of a user reading or editing the active document.

7. The method of claim 1, wherein generating, via the processor, a contextual metadata tag comprises generating a movement tag indicating a movement of a device while the active document was read or edited.

8. A computer program product for filtering document search results, the computer program product comprising a computer readable storage medium having stored thereon:

first program instructions programmed to receive contextual data comprising a facial movement associated with an active document;

second program instructions programmed to detect a response associated with the active document based on the received contextual data;

third program instructions programmed to generate a contextual metadata tag based on the detected response to the active document;

fourth program instructions programmed to receive a query comprising a contextual keyword corresponding to the contextual metadata tag;

fifth program instructions programmed to filter search results received in response to the query based on the contextual metadata tag; and

sixth program instructions programmed to display a list of the filtered search results.

9. The computer program product of claim 8, comprising program code executable by a processor to receive contextual data comprising a document accessed before or after the active document, a time, a global positioning satellite (GPS) location, or any combination thereof.

10. The computer program product of claim 8, comprising program code executable by the processor to display categories of contextual metadata tags in response to detecting that the filter search results exceed a predetermined threshold.

11. The computer program product of claim 8, comprising program code executable by the processor to generate a contextual metadata tag for the active document based on a previously active document and a subsequently active document, wherein the contextual data comprises previously active documents and subsequently active documents for the active document.

12. The computer program product of claim 8, comprising program code executable by the processor to generate a mood tag based on the contextual data, wherein the contextual data further comprises images of a face associated with the active document.

13. The computer program product of claim 8, comprising program code executable by the processor to generate a movement tag in response to detecting a change in location of a device displaying the active document.

14. A computer system for filtering document search results, the computer system comprising:

a processor(s) set; and

a computer readable storage medium;

wherein;

the processor set is structured, located, connected and/or programmed to run program instructions stored on the computer readable storage medium; and

the program instructions include;

first program instructions programmed to receive contextual data comprising a facial movement associated with an active document;

second program instructions programmed to detect a response associated with the active document based on the received contextual data;

third program instructions programmed to generate a contextual metadata tag based on the detected response to the active document;

fourth program instructions programmed to receive a query comprising a contextual keyword corresponding to the contextual metadata tag;

fifth program instructions programmed to filter search results received in response to the query based on the contextual metadata tag; and

sixth program instructions programmed to display a list of the filtered search results.

15. The computer system of claim 14, wherein the facial movement comprises an eye movement and the response comprises an emotional response detected based on the contextual data.

16. The computer system of claim 14, wherein the contextual data comprises an image of a face of a user reading the active document, wherein the detected response comprises a facial expression.

17. The computer system of claim 14, wherein the contextual data comprises a document accessed before or after the active document.

18. The computer system of claim 14, wherein the contextual data comprises a time and global positioning satellite (GPS) information.

19. The computer system of claim 14, wherein the contextual keyword comprises one of a plurality of contextual keywords displayed in response to detecting that the search results received in response to the query exceed a predetermined threshold number of search results.

20. The computer system of claim 14, wherein a processor is to store the generated metadata tag appended to the active document.
