Abstract: Examples described herein include methods and computing systems which may include examples of mapping watermark metadata to tagged signatures and matching those tagged signatures to mapped reference signatures. A tagged signature is a signature that is identified using a mapping of watermark metadata. The mapping to watermark metadata of a tagged signature (e.g., having stored data associated with the tagged signature) can include the use of a source identifier (e.g., a station identification), timestamps, a media asset identifier, and a time-in-content range. Computing systems are employed to identify media content using matched reference signatures, thereby also facilitating crediting of media content.

Abstract: Methods, apparatus, systems, and articles of manufacture to identify an episode number based on fingerprint and matched viewing information are disclosed. An example method includes processing meter data to identify a presented media based on a bumper included in a media, filtering the meter data based on the identification of the media, selecting a candidate episode, the candidate episode not associated with a known episode label, determining whether the candidate episode appears sequentially after a known episode for a threshold number of presentation locations, and labeling the candidate episode as the next sequential episode after the known episode in response to determining that the candidate episode appears sequentially after the known episode for the threshold number of presentation locations.

Abstract: Methods, apparatus, systems and articles of manufacture to identify media sources are disclosed. Example apparatus disclosed herein include an exclusivity determiner, a unique asset identifier, and a signature matcher. The exclusivity determiner is to determine whether media is exclusive to a provider. The unique asset identifier is to associate a first signature of the media with the provider if the media is exclusive to the provider. The signature matcher is to identify the provider based on a second signature, the second signature matching the first signature, the second signature extracted from media presented at a media presentation location.

Abstract: Methods, apparatus, systems, and articles of manufacture to accurately credit streaming sessions are disclosed. A meter device records streaming session information. Cluster creation circuitry trains a model by grouping information from multiple streaming sessions into clusters, wherein all streaming sessions within a given cluster have matching media and streaming sources. Model executor circuitry assigns incoming streaming session information to a cluster or to noise. Cluster creation circuitry edits the model by creating new clusters out of information from multiple streaming sessions with similar attributes that were originally labeled as noise. By only crediting streaming session information assigned to a cluster, the disclosed system avoids crediting illogical streaming session information, such as the crediting of media to a streaming source that does not offer said media.
