Method and apparatus for survey processing
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.
1. A real-time survey analysis system, said system comprising:
a runtime engine for receiving survey data;
at least one summarization coalescer for sorting survey data and routing said survey data to at least one statistical summarization engine, said at least one summarization coalescer sorting and routing said survey data based on at least one criterion; and
at least one statistical summarization engine for analyzing said survey data in real time to perform at least one of summarization and statistical analysis,
wherein said summarization coalescer compares a plurality of survey data with a history list of recently processed surveys to route said plurality of survey data to said at least one statistical summarization engine.
2. The system of claim 1 , wherein said at least one summarization coalescer receives a stream of survey data from a plurality of sources.
3. The system of claim 1 , wherein said survey data comprises at least one of survey completion data and new survey reporting group data.
4. The system of claim 1 , wherein said at least one criterion further comprises at least one criterion to allow said summarization coalescer to group incoming survey data in an optimal order for processing.
5. The system of claim 1 , further comprising a reporting engine for generating a new group for survey reporting.
6. The system of claim 1 , further comprising a database for storing at least one of survey data and survey reporting group definitions.
7. The system of claim 1 , further comprising a user interface for engine ring survey data.
8. The system of claim 7 , wherein said user interface further comprises a Web-based user interface.
9. A real-time survey analysis system, said system comprising:
a runtime engine for receiving survey data;
at least one summarization coalescer for sorting survey data and routing said survey data to at least one statistical summarization engine, said at least one summarization coalescer sorting and routing said survey data based on at least one criterion; and
at least one statistical summarization engine for analyzing said survey data in real time to perform at least one of summarization and statistical analysis,
wherein said at least one statistical summarization engine reads a previous summarization state from a database to mark a starting point from incremental statistic computation using said survey data.
10. The system of claim 9 , wherein said at least one summarization coalescer receives a stream of survey data from a plurality of sources.
11. The system of claim 9 , wherein said survey data comprises at least one of survey completion data and new survey reporting group data.
12. The system of claim 9 , wherein said at least one criterion further comprises at least one criterion to allow said summarization coalescer to group incoming survey data in an optimal order for processing.
13. The system of claim 9 , further comprising a reporting engine for generating a new group for survey reporting.
14. The system of claim 9 , further comprising a database for storing at least one of survey data and survey reporting group definitions.
15. The system of claim 9 , further comprising a user interface for entering survey data.
16. The system of claim 15 , wherein said user interface further comprises a Web-based user interface.
17. A method for real-time processing of survey data, said method comprising:
receiving, at a runtime engine, survey data;
sorting, by at least one summarization coalescer, the survey data and routing said survey data to at least one statistical summarization engine,
wherein said sorting and routing of said survey data are based on at least one criterion;
analyzing, by the at least one statistical summarization engine, said survey data in real time to perform at least one of summarization and statistical analysis,
wherein said at least one statistical summarization engine read a previous summarization state from a database to mark a starting point from incremental statistic computation using said survey data.
