Certain embodiments of the present invention provide a system and method for improved, real-time survey data processing and analysis. Certain embodiments use distributed computing techniques to perform statistical calculations for survey data, such as general purpose and multi-rater feedback data. Certain embodiments use a matrix structure coupled with hash tables for efficient processing of survey statistics across an entire survey. Certain embodiments use a criteria parser based on externally definable lexical rules to determine which survey responses belong to which groups. Certain embodiments allow coalescing of summarization requests between summarization servers to allow for peak performance across any number of surveys. Certain embodiments provide a scalable, adaptable survey processing system and method that processes survey results in real time, allowing for immediate feedback during the survey process.
