The invention discloses a method and system for extracting entity attribute information in a text, and the method comprises the steps: obtaining a target text, carrying out word segmentation of the target text, determining whether the target text after word segmentation contains an entity keyword or not, determining the part-of-speech of a first target segmented word in front of the entity keyword if the target text after word segmentation contains the entity keyword; determining whether the part-of-speech of the first target segmented word conforms to a preset entity attribute rule or not, if yes, adding the first target segmented word into first target entity attribute information, performing entity extraction again in the target text by using the first target entity attribute information as a parameter to obtain an extraction result, and otherwise, performing entity extraction again in the target text; determining second target entity attribute information of the target text according to the extraction result, verifying secondary entity extraction can be performed on the target text while the extracted first target entity attribute information so as to ensure the integrity of final entity attribute information, and the situation of entity extraction missing can be avoided.
Description
technical field [0001] The invention relates to the technical field of text processing, in particular to a method and system for extracting entity attribute information in text. Background technique [0002] Online encyclopedias, also known as online encyclopedias, are encyclopedias that are open to netizens on the Internet. There are two types of online encyclopedias: open and non-open. Users can use the online encyclopedia to query various information resources in a timely and convenient manner.
