DYNAMICALLY ENHANCING AN INSTRUMENT USING MULTI-STEM DEFINITIONS

Abstract:

An instrument such as an assessment or survey is enhanced using multi-stem definitions to allow a respondent to request alternative versions of a question. The rephrase item is formulated using a rephrase engine which accesses a bank having preexisting rephrases that are equivalent to phrases found in the instrument. The candidate selects a particular complexity level for the rephrase such as simple or elaborate. Rephrasing can be provided automatically based on a timer for answering the item. The system may set a maximum number of allowable rephrases. An analytical engine can be utilized in conjunction with the present invention to analyze requests from multiple candidates. This analysis may show that a particular item is difficult to understand, and the engine can correspondingly suggest to a moderator of the instrument that it be modified by replacing the particular item with a rephrase item.
