Abstract: Some embodiments provide a system that facilitates use of a question-and-answer system. During operation, the system determines a community value of a question submitted by a first user to the question-and-answer system. Next, the system prioritizes answering of the question by a second user in the question-and-answer system based on the community value.

Abstract: Some embodiments provide a system that facilitates use of a question-and-answer system. During operation, the system determines a business value of a question submitted by a first user to the question-and-answer system. Next, the system prioritizes answering of the question by a second user in the question-and-answer system based on the business value.

Abstract: An electronic device-controlled method can include receiving responses to a question of an online survey, determining an average daily response for the question, and determining an upper confidence level and a lower confidence level for the question. A subsequent determination can be made as to whether the question is stable based on the average daily response and upper and lower confidence levels over a specified period of time.

Abstract: The disclosed embodiments provide a system that facilitates use of an application. During operation, the system obtains an activity history of interaction between the user and the application during use of the application by the user. Next, the system applies a predictive model to the activity history to predict a probability of a user action in the application. Finally, the system facilitates subsequent real-time use of the application by the user based on the probability of the user action.

Abstract: Some embodiments provide a system that monitors use of an application. During operation, the system uses the application to track a set of interactions between a set of users and the application without impacting the performance of the application. Next, the system stores the interactions as the interactions are detected by the application. Finally, for each user from the set of users, the system periodically processes a subset of the stored interactions associated with the user to obtain an activity history for the user, wherein the activity history is used to facilitate subsequent real-time use of the application by the user.
