Abstract: The present disclosure provides a method and system for automatically monitoring and identifying water seepage of a segment joint of a subway shield tunnel. The method includes: 1): grinding a water-sensitive material and then mixing with a waterproof material to form a color-developing agent; 2): coating the color-developing agent on two sides extending from a construction joint and/or a deformation joint of a tunnel lining as a center line, to form a color-developing layer; and 3) obtaining a color development feature of the color-developing layer, and identifying water seepage based on the color development feature. According to the present disclosure, a water seepage amount can be determined based on the color development feature of the color-developing layer around the construction joint and/or the deformation joint of the tunnel lining, which facilitates monitoring of the water seepage amount around the construction joint and/or the deformation joint.

Abstract: A method, apparatus and system for providing search prompt information based on a session. The method is implemented as follows. A hot word list and a session message are obtained, and a word is selected from the session message according to a preset word selecting policy. The selected word is matched with the hot word list, and a word matching the hot word list is taken as a search prompt word, and search link information is set for the search prompt word. The search prompt word is marked.
