SAAS services for automatically detecting and correcting data errors without human knowledge or input by combining artificial intelligence (AI), big data, and medical ontologies. For example, the platform integrates disparate datasets to assist stakeholders to identify hidden anomalies (potential errors) in their data. The platform can assess the risk of those potential errors and suggest next steps that range from automated corrective action to leaving the errors as is. Many of these potential errors can highlight gaps in data or processes that can be turned into monetizable insights
