Embodiment 1

[0033] Concrete implementation of the present invention is mainly divided into two major modules:

[0034] Module 1: Constructing a knowledge map in the field of ethnic minorities;

[0035] Module 2: Function realization of intelligent question answering system;

[0036] For Module 1, a method for constructing a knowledge map in the field of ethnic minorities is provided, including the following steps:

[0037] Step 1: Atlas Design

[0038] Designing a minority domain map is the most important step in building an app. After analyzing the ethnic structure and current situation, the present invention sets the entity categories included in the atlas to include: ethnic Chinese names, nicknames, population, distribution areas, languages, language families, language families, ethnic categories, characters, beliefs, festivals, buildings, Totem, daily diet, dietary taboos, clothing, historical figures, ethnic art, each entity category contains multiple entities. Some entities cont...

Embodiment 2

[0056] Depend on figure 1 As shown, a method for constructing a question answering system for knowledge graphs in minority areas is mainly constructed from five aspects.

[0057] Step 1: Framework design of minority knowledge;

[0058] Step 2: Acquisition of knowledge in the field of ethnic minorities;

[0059] Step 3: Integration of minority field knowledge;

[0060] Step 4: Storage of minority domain knowledge;

[0061] Step 5: Intelligent Q&A of minority domain knowledge;

[0062] Each step is described in detail below.

[0063] Step 1: According to the characteristics of ethnic minority knowledge, compare and analyze the information from encyclopedia websites and some ethnic websites, determine the fields involved in ethnic minority knowledge, unify their planning, and determine the entity categories and entity attributes in the knowledge map and entity relationship. For example, set the ethnic category, which includes 56 ethnic groups and some unidentified ethnic grou...

Abstract

The invention discloses a minority field intelligent question-answering method based on a knowledge graph, and belongs to the field of question-answering methods based on artificial intelligence. According to the technical scheme, the method comprises the following steps: designing an atlas according to correlation between entity categories; obtaining an original corpus constructed by the minoritydomain knowledge graph according to the graph design; processing the original corpus; construction of knowledge graph. The minority domain intelligent question-answering method based on the knowledgegraph has the beneficial effects that by constructing the minority domain knowledge graph, related data can be integrated and normalized, related knowledge of minority can be more reasonably appliedto practical application, and spreading of national culture is facilitated; and the knowledge graph is applied to intelligent questions and answers, so that the retrieval efficiency and the absorptionefficiency of national knowledge can be improved.

Description

technical field [0001] The invention belongs to the field of question answering methods based on artificial intelligence, in particular to a question answering method based on knowledge graphs and a question answering system for ethnic minorities based on the method. Background technique [0002] In recent years, China is a multi-ethnic country with a history of more than 5,000 years. The 56 ethnic groups are distributed all over the country with the characteristics of "living together in large groups and living in small groups", forming a big Chinese family together. Ethnic unity and common progress are the symbols of a countrys soft power. To enhance national self-confidence, enhance national identity, and ensure the long-term stability of the country, it is even more necessary for the joint efforts of the 56 ethnic groups. With the guidance of national policies and the dissemination of information, more and more knowledge about ethnic groups has been gradually accumulated...
