Research on Mongolian-Chinese Bilingual Q&A System for the Theme of the Five Livestock Based on Knowledge Graph
(five livestock)in Mongolian refers to horses,cattle,camels,sheep,and goats.In Mongolian,the proprietary vocabulary related to the Five Livestock is very rich and color-ful,with distinct ethnic characteristics.For example,the category,gender,age,hair color and temperament of the five livestock have detailed names.There are many common names or dialect lo-cal words.The five-livestock words form a complete semantic field.However,in the field of Mongo-lian information processing,it lacks search engines similar to Baidu Encyclopedia and the applica-tion of the knowledge graph technology.This paper uses structured Mongolian five animal data as the main source to extract the entities,attributes and relationships of five animal knowledge to construct a Mongolian-Chinese bilingual five animal domain Knowledge Graph,then based on this Knowledge Graph,optimize entity recognition operations using a combination of AC automata algorithm and text similarity algorithm.Through the multi-classification model determines query intention,using col-lected Mongolian Chinese bilingual question words and sentences as input for the classification mod-el,to improve the accuracy of sentence meaning analysis.TF-IDF and Embedding features are used to build classification models,they include Linear SVM,Nonlinear SVM,Naive Bayes Model,Lo-gistic Regression,Random Forest,XGBoost and LightGBM.The experiments show that the Linear SVM classification model established by embedding features has the best classification effect.We complete Mongolian and Chinese bilingual automatic question answering based on the knowledge graph,and realize the question answering system through question sentence understanding,semantic matching,answer retrieval,and other operations.We randomly select 300 Mongolian and Chinese bilingual Q&A pairs from five categories to test the system performance,the average accuracy is 89.2％.It provides a strong platform for the dissemination of Mongolian five livestock knowledge and disease questions and answers.
