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 4):
The information extraction method of  claim 3 , wherein obtaining the ranking of the plurality of entities and the ranking of the plurality of candidate attributes comprises:\n calculating a score for each of the plurality of entities based on the entity-attribute graph, a score for each of the plurality of candidate attributes calculated at time t, and a score coefficient for each of the plurality of entities derived from one or more of the plurality of correlation coefficients; calculating a score for each of the plurality of candidate attributes based on the entity-attribute graph, a score for each of the plurality of entities calculated at time t, and a score coefficient for each of the plurality of candidate attributes derived from one or more of the plurality of correlation coefficients; and reiterating calculating the score for each of the plurality of entities and the score for each of the plurality of candidate attributes for a number of times.
