¿µ¹®³»¿ë¿ä¾à The standard defines the different information elements and metadata structures which are formalized by the question analysis for open-domain question answering systems and provides the information recognition guidelines for each element.

The major information elements to formalize the meaning of the questions are as follows:
a) The basic question analysis information which stores the input question in natural language and the results of the analyzed question
b) Question decomposition information that decomposes the complex question into questions of minimum units and formalizes the relation between the decomposed questions.
c) Question classification information based on multiple perspectives to establish the various answering strategies for each question.
d) Information on the classification of question types based on WH-question words, which is an important clue for question analysis.
e) Question focus information related to the part of the natural language question that indicates the correct answer
f) Answers type information that limits the semantic type of the correct answers searched.
g) Question topic information that identifies the entity for the object of the question.
h) Answer constraining information that recognizes the clues that constrain correct answers.
The standard defines the metadata in JSON format that formalizes the question meaning based on the major information elements defined above for the question analysis and establishes the criteria for recognizing the values of the metadata from the natural language questions.
