Abstract

Disclosed are methods and apparatus for correlating metadata from a plurality of different sources. The methods and apparatus may use an order for the data sources. The metadata from each of the data sources may be divided or split into one or more chunks. The metadata from each of the chunks may be filtered and sorted, e.g., to ensure that the metadata relate to the same multimedia content. The metadata chunks from the first data source in the order and the second data source in the order may then be aligned to produce currently aligned metadata. The metadata data chunks from the next data source in the order may then be aligned with the currently aligned metadata to produce new currently aligned metadata. This process may be repeated until the metadata from all of the sources are aligned, thereby providing a set of correlated metadata.

Dependent claims

A method of correlating metadata from a plurality of different sources, the metadata relating to same multimedia content, the method comprising:

providing an order for data sources;
receiving, by one or more processors, from each of the data sources, respective metadata relating to the same multimedia content;
dividing, by the one or more processors, the metadata from each of the data sources into one or more metadata chunks;
selecting, by the one or more processors, the metadata chunks that originated from a first data source in the order;
selecting, by the one or more processors, the metadata chunks that originated from a second data source in the order;
performing, by the one or more processors, an alignment process to align the metadata chunks that originated from the first data source with the metadata chunks that originated from the second data source, thereby providing currently aligned metadata;
iteratively performing, by the one or more processors, steps (i) to (iii) until steps (i) to (iii) have been performed using the metadata from each of the data sources, wherein:
step (i) comprises selecting the metadata chunks that originated from a next data source in the order, the metadata chunks selected at step (i) having not previously been selected;
step (ii) comprises performing the alignment process to align the metadata chunks selected at step (i) with the currently aligned metadata, thereby providing updated aligned metadata;
and
step (iii) comprises defining the updated aligned metadata resulting from step (ii) as the currently aligned metadata;
and defining as correlated metadata, the currently aligned metadata produced by iteratively performing steps (i) to (ii) until steps (i) to (ii) have been performed using the metadata from each of the data sources.
