A network device, system, and method are directed towards providing user context information to improve relevancy of a search result, or other content, provided to a user. A context service may provide a common retrieval interface (CRI) that reflects the capabilities available to a content service application (CSA). The CSA may provide limited information about the user to the context service and may specify user context information being sought. The context service provides at least some of the known user information to various context analysis services to request the user context information, and receives back user context information along with a confidence level indicating a percentage of confidence the context analysis service may have for the results. The context service then selects user context information based on weighted confidence levels, and provides the results to the CSA, to improve the relevancy of information provided to the user.
