Method and device for establishing knowledge base

Abstract

The application discloses a method for establishing a knowledge base, which is used for realizing automatic generation of the knowledge base and improving the accuracy of the knowledge base. The method comprises the following steps: a basic data processing layer in a computer apparatus acquires a sentence in a webpage; an excavation layer in the computer apparatus separates the words of the sentence; the excavation layer matches a pre-set sign word corresponding to a first type in the knowledge base with the separated words; when at least one separated word is successfully matched, the excavation layer adds an unknown character string adjacent to the successfully matched word in the sentence into the first type to serve as a first item; when a word in the sentence is matched with a second item of a second type in the knowledge base, the excavation layer judges whether a relationship is established between the first type and the second type; if yes, the excavation layer establishes a relationship between the first item and the second item. The application further discloses a device for realizing the method and a method and a device for searching information.

Description

technical field [0001] The present application relates to the field of computer and communication, in particular to a method and device for constructing a knowledge base. Background technique [0002] Computer and Internet technologies have been widely used, and resource sharing is its main feature. How to search for the information they need from the huge information resources is a problem that users generally care about. Therefore, information search technology emerges at the historic moment. [0003] One of the main search techniques is keyword search. The user enters a keyword in the search bar, and the search engine performs a search based on the keyword, and searches out all web pages containing the keyword as much as possible. However, a word itself has multiple meanings, and a word may also have multiple interpretations or applications in different industries and fields. Perhaps most of the meanings are distracting items for search users. Web pages based on these ...

Problems solved by technology

[0005] However, the current HowNet is manually established and organized, and usually only covers high-frequency content, and the network content covered is limited

Moreover, with the development of the network, the amount of information increases exponentially, and the speed of manual update of HowNet is far lower than the growth rate of information amount, resulting in unsatisfactory search results
