Problems solved by technology

[0005] The existing method for determining the hyponym relationship has a single hyponym relationship and weak generalization, which cannot meet the needs of entity question answering
For example, for the question "What are the famous scenic spots in Japan?", most of the answers include "Hokkaido". Using the existing method for determining the hyponymy relationship, the hyponymy relationship between "Hokkaido" and "sightseeing spots" can be obtained, but it is not obtained. "Hokkaido" has a superordinate relationship with "area". Therefore, when the question "What areas are there in Japan?" is encountered, the answer "Hokkaido" will be ignored.

Abstract

The embodiment of the invention discloses a method, a device, a server and a storage medium for determining the upper and lower position relationship. The method comprises the following steps: obtaining a first lower word set corresponding to a first upper word and the first upper word and a second lower word set corresponding to a second upper word and the second upper word; determining an inclusion relationship between the first lower word set and the second lower word set; determining a superordinate-superordinate relationship between the first superordinate word and the second superordinate word according to an inclusion relationship between the first subordinate word set and the second subordinate word set. Superior-inferior relationship is fuller and more generalized, which can meetthe needs of user entity question answering.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of the Internet, and in particular to a method, device, server, and storage medium for determining a subordinate relationship. Background technique [0002] The hyponymy relationship is a basic semantic relationship, which is often used in the construction and verification of ontologies, knowledge bases, and dictionaries. From the perspective of technical implementation, the acquisition of hyponymy relations provides important support for the acquisition of other information. The hypernym of an entity is a generalization of a class of entities with common characteristics. For example, the hypernym of "red", "yellow", and "green" is "color", and the hypernym of "car" and "truck" is "car" . With this hyponymy relationship as prior knowledge, the range of entity answers can be quickly narrowed down, which helps entity question answering algorithms to find answers quickly and accurate...
