The subject disclosure is directed towards a technology by which the accuracy of context-based information provided by at least one data source for received context data is increased. Correctness information received in association with usage of looked up context-based information is logged. The correctness information may be processed to increase the overall accuracy by correcting a data source, and/or by creating a blended data source that includes the most likely accurate portions (segments) from among multiple data sources as determined via the correctness information.

Increasing the accuracy of information returned for context signals

Query results are pre-cached for a substantial portion of or all queries that are likely to be issued by users. One query can be entirely different from another query, yet because corresponding query results are pre-cached, the database need not be accessed, improving response performance. Pre-cached queries are also distributed into multiple partitions to apportion work among multiple computing machines to further enhance performance and provide redundancy in case of the failure of any particular partition. Pre-cached query results are selectively refreshed so that users may enjoy up-to-date information by focusing on queries that are popular as well as queries that are old.
