A method carried out by a computer device, characterized by the method comprising: obtaining (S202, S5102) an address text and a fence identifier, which corresponds to the address text; performing semantic extension on the address text to obtain a plurality of extended addresses, wherein the semantic extension is a process of predicting, by deleting, extending, or replacing an address element of an address text, other more address texts that can indicate address location information similar to that of the address text; converting (S206, S5402) each of the extended addresses into corresponding geographic coordinates to obtain a plurality of possible geographic coordinates; recognizing a key address element of each of the plurality of extended addresses; wherein the recognizing the key address element of each of the plurality of extended addresses comprises: constructing a path graph corresponding to the address text and comprising two or more paths by using each address element comprised in the plurality of extended addresses as a node and using a neighborhood relationship between different address elements in a same extended address to connect a previous address element node to a subsequent address element node by a directed edge; calculating a node value of each node in the path graph and a directed edge value of each directed edge in the path graph; determining an optimal path amongst the two or more paths based on each node value and each directed edge value; and determining each address element comprised in the optimal path as the key address element; screening the possible geographic coordinates depending on whether an extended address corresponding to a possible geographic coordinate comprises all recognized key address elements and whether the possible geographic coordinate is located in a target fence corresponding to the fence identifier; and determining, according to a clustering feature of each of the screened possible geographic coordinates, one of the screened possible geographic coordinates as a processed coordinate, which is the geographic coordinate of the address text. obtaining (S202, S5102) an address text and a fence identifier, which corresponds to the address text; performing semantic extension on the address text to obtain a plurality of extended addresses, wherein the semantic extension is a process of predicting, by deleting, extending, or replacing an address element of an address text, other more address texts that can indicate address location information similar to that of the address text; converting (S206, S5402) each of the extended addresses into corresponding geographic coordinates to obtain a plurality of possible geographic coordinates; recognizing a key address element of each of the plurality of extended addresses; wherein the recognizing the key address element of each of the plurality of extended addresses comprises: constructing a path graph corresponding to the address text and comprising two or more paths by using each address element comprised in the plurality of extended addresses as a node and using a neighborhood relationship between different address elements in a same extended address to connect a previous address element node to a subsequent address element node by a directed edge; calculating a node value of each node in the path graph and a directed edge value of each directed edge in the path graph; determining an optimal path amongst the two or more paths based on each node value and each directed edge value; and determining each address element comprised in the optimal path as the key address element; screening the possible geographic coordinates depending on whether an extended address corresponding to a possible geographic coordinate comprises all recognized key address elements and whether the possible geographic coordinate is located in a target fence corresponding to the fence identifier; and determining, according to a clustering feature of each of the screened possible geographic coordinates, one of the screened possible geographic coordinates as a processed coordinate, which is the geographic coordinate of the address text.
