Abstract

Systems and methods for aggregating user feedback associated with digital media files is provided. User feedback is received from a user that includes metadata which may correspond to a digital media file. A batch of such user feedback is received and may be filtered to discard any low quality user feedback entries. It then may be determined whether a user feedback entry corresponds to an existing metadata record stored as aggregated feedback. If not, the new user feedback entry is added to the aggregated feedback. If there is an existing metadata record which corresponds to the user feedback entry, the metadata contained in the entry may be used to edit the existing metadata record.

Claims

1. One or more computer storage media having computer-executable instructions embodied thereon for performing a method of aggregating user feedback of metadata, the method comprising:

maintaining a database of metadata records, the metadata records each corresponding to one or more media files;

receiving a batch of user-provided data entries from one or more users, the data entries each corresponding to a specific media file;

determining whether each data entry is of a predetermined quality; and

if a data entry is determined to be of a predetermined quality, aggregating the data entry with the database of metadata records.

2. The computer storage media of claim 1, wherein the data entries each comprise a physical ID entry and a textual entry.

3. The computer storage media of claim 2, wherein the physical ID entry comprises a table of contents (TOC) entry having one or more tracks associated therewith, and wherein the textual entry has one or more tracks associated therewith.

4. The computer storage media of claim 3, wherein each data entry is of a predetermined quality if the number of tracks associated with the TOC entry is within a predetermined threshold of the number of tracks associated with the textual entry.

5. The computer storage media of claim 3, wherein the tracks associated with the TOC entry each have a title associated therewith and wherein the tracks associated with the textual entry each have a title associated therewith.

6. The computer storage media of claim 3, wherein each data entry is of a predetermined quality if a predetermined amount of the titles associated with the TOC entry are identical to the titles associated with the textual entry.

7. The computer storage media of claim 5, wherein each data entry is of a predetermined quality if at least half of the titles associated with the TOC entry are identical to the titles associated with the textual entry.

8. The computer storage media of claim 5, wherein a data entry is of a predetermined quality if all of the titles associated with the TOC entry are identical to the titles associated with the textual entry.

9. The computer storage media of claim 1, wherein the method further comprises sending the data entry to a real time database if the data entry is determined to be of a predetermined quality.

10. A computer system embodied on at least one computer storage media having computer-executable instructions embodied thereon for performing a method of aggregating user feedback of metadata, wherein the system includes a database of metadata records stored therein corresponding to one or more media files, the system comprising:

a receiving component configured for receiving a batch of one or more user-provided data entries, the data entries each corresponding to one or more media files; and

an aggregating component configured for aggregating each data entry with the database of metadata records if the data entry corresponds to a metadata record in the database, wherein the data entry and the metadata record are not identical.

11. The computer system of claim 10, wherein the data entry comprises a physical ID entry and a textual entry associated therewith, and wherein the metadata record comprises a physical ID entry and a textual entry, and the data entry corresponds to the metadata record if the physical ID entry of the data entry corresponds to the physical ID entry of the metadata record.

12. The computer system of claim 10, further comprising a filtering component configured to filter the batch of data entries based on quality of each data entry.

13. The computer system of claim 10, further comprising a storage component configured to store a database of metadata records, the metadata records each corresponding to one or more media files.

14. The computer system of claim 10, further comprising a statistic generating component configured to generate statistics based on the stability of each metadata record.

15. One or more computer storage media having computer-executable instructions embodied thereon for performing a method of aggregating user feedback of metadata, the method comprising:

maintaining a database of metadata records, the metadata records each corresponding to one or more media files, wherein the metadata records each comprise a physical ID entry and a textual entry;

receiving a batch of user-provided data entries from one or more users, the data entries each corresponding to a specific media file, wherein the data entries each comprise a physical ID entry and a textual entry;

determining whether the physical ID entry of each data entry corresponds to a physical ID entry of a metadata record;

if it is determined that the physical entry of a data entry corresponds to the physical ID entry of a metadata record, aggregating the corresponding data entry and metadata record by editing the corresponding metadata record; and

if it is determined that the physical ID entry of a data entry does not correspond to the physical ID entry of a metadata record, aggregating the data entry by adding the data entry to the database.

16. The computer storage media of claim 15, wherein the method further comprises aggregating one or more data entries having a corresponding physical ID entry.

17. The computer storage media of claim 15, wherein each textual entry of a data entry comprises an album title, and wherein the method further comprises aggregating one or more data entries having a corresponding album title.

18. The computer storage media of claim 17, wherein the textual entry of each metadata record comprises an album title, and wherein the method further comprises determining whether the album title of a data entry corresponds to an album title of a metadata record;

and if so, aggregating the corresponding data entry and metadata record.

19. The computer storage media of claim 15, wherein each textual entry of a data entry comprises an artist entry, and wherein the method further comprises aggregating one or more data entries having a corresponding artist entry.

20. The computer storage media of claim 19, wherein the textual entry of each metadata record comprises an artist entry, and wherein the method further comprises determining whether the artist entry of a data entry corresponds to an artist entry of a metadata record;

and if so, aggregating the corresponding data entry and metadata record.
