    EI process starts with decision maker expressing the decision problem as a form of document. This is called initial demand in [7]. Such initial demand is 
                                                                                                                                                             
the materialized knowledge of the decision maker based on available information. Interactions among the actors on the initial demand generate knowledge that 
                                                                                                                                                             
could give mutual and clearer understanding of the decision problem goal(s). It might involve defining or explaining some basic terms that could give a clearer 
                                                                                                                                                             
picture of the perception of the decision maker, who may have formulated such decision problem, as well as identifying and understanding the goal to be 
                                                                                                                                                             
achieved. Such knowledge could be captured through annotation. Shared perceptions give more insight to possible solution as actors will have clearer 
                                                                                                                                                             
understanding of one another's perception. Individual may share their perceptions of the decision problem through annotation in a collaborative environment. 
                                                                                                                                                             
The use of annotation as a means for collaborators to share one another's perception could be done synchronously or asynchronously. With synchronous
