To provide a question analysis method, a device, a knowledge-based question answering system, and an electronic device that allow users to directly answer raised questions in natural language.SOLUTION: A question analysis method comprises: a step of analyzing questions to obtain N linear sequences that are integers greater than 1; a step of respectively converting the N linear sequences to N topology maps; a step of calculating a semantic matching degree between each of the N topology maps and the question; and a step of selecting the topology map which has the highest semantic matching degree with the question as a query graph of the question from the N topology maps.SELECTED DRAWING: Figure 1 【課題】ユーザが自然言語の形で提起した質問に直接答えることができる質問分析方法、装置、知識ベース質問応答システム及び電子機器を提供する。【解決手段】質問分析方法は、質問を分析して１より大きい整数であるＮ個の線形シーケンスを得るステップと、Ｎ個の線形シーケンスをそれぞれＮ個のトポロジマップに変換するステップと、Ｎ個のトポロジマップの各トポロジマップと質問とのセマンティックマッチング度をそれぞれ算出するステップと、Ｎ個のトポロジマップから、質問とのセマンティックマッチング度が最も高いトポロジマップを質問のクエリグラフとして選択するステップと、を含む。【選択図】図１
