Abstract:
1. 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.
