1. A computing system to create a reference signature asset from signature fragments, the computing system comprising:
a processor; and
a non-transitory computer-readable storage medium, having stored thereon program instructions that, upon execution by the processor, cause performance of a set of operations to:
sort a group of matched signature fragments into a first list by order of fragment start times and a second list by descending order of fragment lengths, the matched signature fragments corresponding to a same piece of media, respective ones of the matched signature fragments to represent corresponding portions of the piece of media;
select a first signature fragment from the first list and a second signature fragment from the second list, the first signature fragment and the second signature fragment to overlap by a first threshold and to collectively represent a continuous segment of the piece of media; and
in response to a determination that a difference between a segment end time of the second signature fragment and a segment start time of the first signature fragment meets a second threshold, combine the first signature fragment and the second signature fragment to create the reference signature asset.
