A system and method is provided that provides an early indication of consensus of opinion among a number of users regarding an event or observation indicated by a user. Such an opinion may be interesting to an information consumer, who may be interested in determining the outcome of the consensus relating to the event or observation, or may otherwise desire to perform surveillance or survey of a particular issue or subject. Such recognition of early events or observations may be useful in different areas, such as healthcare, finance, etc., where initial observations, if provided early, allow resulting decisions to be made much earlier. The opinion may, for instance, be used as an early indicator of problem with a product, company, etc. that would permit an information consumer to perform an action at a much earlier point than if he / she relied on traditional sources of information. Thus, such opinion information may be invaluable as a tool for monitoring events.
