Classification of clustered documents based on similarity scores

A system comprising:

• memory;
• and
• one or more processors coupled to the memory, wherein the memory stores instructions operable, when executed by the one or more processors, to cause the one or more processors to perform operations comprising:
• receiving a set of clusters of documents;
• for each cluster in the set of clusters, calculating a similarity score for the cluster wherein the similarity score is based at least in part on features included in the documents in the cluster and indicates a measure of similarity of the documents in the cluster;
• for each cluster associated with a respective similarity score greater than a first threshold, identifying the cluster as satisfying a quality assurance requirement;
• for each cluster associated with a respective similarity score less than a second threshold, identifying the cluster as failing the quality assurance requirement, wherein the second threshold is less than the first threshold;
• for each cluster associated with a similarity score less than or equal to the first threshold value and greater than or equal to the second threshold value, reviewing at least a subset of documents in the cluster to determine whether the cluster satisfies the quality assurance requirement;
• and
• associating a label with each cluster in the set of clusters, wherein the label indicates whether the cluster satisfied the quality assurance requirement.

A non-transitory computer-readable storage device storing a computer program product, the computer program product having instructions operable to cause one or more data processing apparatus to perform operations comprising:

• receiving a set of clusters of documents;
• for each cluster in the set of clusters, calculating a similarity score for the cluster wherein the similarity score is based at least in part on features included in the documents in the cluster and indicates a measure of similarity of the documents in the cluster;
• for each cluster associated with a respective similarity score greater than a first threshold, identifying the cluster as satisfying a quality assurance requirement;
• for each cluster associated with a respective similarity score less than a second threshold, identifying the cluster as failing the quality assurance requirement, wherein the second threshold is less than the first threshold;
• for each cluster associated with a similarity score less than or equal to the first threshold value and greater than or equal to the second threshold value, reviewing at least a subset of documents in the cluster to determine whether the cluster satisfies the quality assurance requirement;
• and
• associating a label with each cluster in the set of clusters, wherein the label indicates whether the cluster satisfied the quality assurance requirement.
