Graphical Perspective of Qualitative Analysis
X means the information extraction system  has the capability; X* means the information extraction system  has the ability as long as the training corpus can accommodate the required training data; ? Shows that the systems can has the ability in somewhat degree; * means that the extraction pattern itself doesn’t show the ability, but the overall system has the capability.
