Introduction to man-machine question and answer system

Introduces 2 open source human-machine question and answer systems implemented in Java:

1, Questionansweringsystem

questionansweringsystem

2, Openephyra

Ephyra is a modular and extensible framework for open domain question answering (QA).

The system retrieves accurate answers to natural language questions from the Web and other sources.

The basic ideas of the two systems are the same, with 4 major similarities:

1, are open-source projects with Java implementation;

2, are to answer natural language questions, such as these questions: testing the human-machine question and answer system intelligence of 3,760 questions;

3, all need to give accurate answers, but not like search engines just need to give the keyword matching page list can be;

4, it is necessary to retrieve text information from the Internet or other data sources.

So where is the difference?

One is for the Chinese language, one is for the English language, there are specific implementation methods such as: the use of Word segmentation algorithm, problem classification algorithm, answer extraction algorithm, answer scoring algorithm, etc. are different.
