Abstract:
The present application discloses an information extraction method. The method includes extracting a plurality of candidate entities and a plurality of candidate attributes from a target corpus based on a plurality of entity seeds of one or more target types in an entity seeds set; establishing a plurality of correlations between the plurality of candidate attributes and a plurality of entities including the plurality of candidate entities and the plurality of entity seeds; and selecting one or more target entities from the plurality of entities and one or more target attributes from the plurality of candidate attributes based on the plurality of correlations.

Claim (Index 5):
The information extraction method of  claim 4 , wherein obtaining the ranking of the plurality of entities and the ranking of the plurality of candidate attributes comprises:\n calculating the score for each of the plurality of entities based on Equation (1): S t + 1 \ue8a0 ( e i ) = \u2211 j \ue89e S t \ue8a0 ( a j ) \u00d7 w i , j \u2211 k \ue89e w k , j ; ( 1 ) and\n calculating the score for each of the plurality of candidate attributes based on Equation (2): \n S t + 1 \ue8a0 ( a j ) = \u2211 i \ue89e S t \ue8a0 ( e i ) \u00d7 w i , j \u2211 k \ue89e w i , p ; ( 2 ) wherein S t+1 (e i ) stands for a score for an entity e i  of the plurality of entities calculated at time (t+1), S t (a j ) stands for a score for an candidate attribute a j  of the plurality of candidate attributes calculated at time t, w i , j \u2211 k \ue89e w k , j stands for the score coefficient for the plurality of entities, w i,j  stands for a weight for an edge between a node corresponding to the entity e i  and a node corresponding to the candidate attribute a j , w k,j  stands for a weight for an edge between a node corresponding to the entity e k  and a node corresponding to the candidate attribute a j , j stands for a number of edges connected to the node corresponding to the entity e i  in the entity-attribute graph, and k stands for a number of edges connected to the node corresponding to the candidate attribute a j  in the entity-attribute graph;\n S t+1 (a j ) stands for a score for the candidate attribute a j  of the plurality of candidate attributes calculated at time (t+1), S t (e i ) stands for a score for the entity e i  of the plurality of entities calculated at time t, \n w i , j \u2211 k \ue89e w i , p stands for the score coefficient for the plurality of candidate attributes, w i,p  stands for a weight for an edge between the node corresponding to the entity e i  and a node corresponding to the candidate attribute a p , i stands for the number of edges connected to the node corresponding to the candidate attribute a j  in the entity-attribute graph, and p stands for the number of edges connected to the node corresponding to the entity e i  in the entity-attribute graph.
