Instant interactive text oriented event identifying and tracking method

The invention discloses an instant interactive text oriented event identifying and tracking method, which comprises the following two steps that: I, in the sorting stage of a turntalking theme category, the turntalking content is represented by an adaptive language feature gather representing mode and the turntalking theme category is sorted by a potential semantic analysis mode that is acquired by training with a supervision layering possibility; II, in the turntalking event identifying and tracking stage, the starting, the continuing and the ending of the event are judged according to the theme category of the turntalking, the time difference of the front and back turntalking and the compactness of the talking staff of the front and back turntalking on the social network grade, wherein (1) the invention sets forward a theory of adaptively adjusting the turntalking compactness degree valve value Th according to the fluctuation size of the time sequence data after the current turntalking, then the adaptive la
