Reducing signature matching uncertainty in media monitoring systems
Abstract:
Methods, apparatus, systems and articles of manufacture to reduce signature matching uncertainty in media monitoring systems are disclosed. Disclosed example apparatus include a signature comparator to compare first neighborhoods of monitored signatures with second neighborhoods of reference signatures to determine a first sequence of successive signature matching results, the first and second neighborhoods having respective neighborhood sizes spanning a first duration. Disclosed example apparatus also include a results selector to select between outputting the first sequence or a second sequence of successive signature matching results for an observation period based on whether discontinuous timestamps are included in the first sequence of successive signature matching results, the second sequence of successive signature matching results determined from comparisons of third neighborhoods of monitored signatures with fourth neighborhoods of reference signatures, the third and fourth neighborhoods having respective neighborhood sizes spanning a second duration of time larger than the first duration of time.
