Zusammenfassung: | To provide a knowledge model creation support system making it possible to efficiently create a knowledge model.SOLUTION: A knowledge model creation support system 30 includes: an object factor acquisition unit 31 that acquires parent factors A and B and a child factor C as an object factor 31a for use in defining relationship information 24; an observation data acquisition unit 32 that acquires observation data 32a concerning factor values of the parent factors A and B and a factor value of the child factor C; a generation unit 36 that generates a conditional probability table 36b, in which a probability equivalent to the factor value of the child factor C is defined in a case where the factor values of the parent factors A and B are regarded as requirements, on the basis of the observation data 32a; and a knowledge model storage unit 38 that regards the generated conditional probability table 36b as the relationship information 24 among the parent factors A and B and the child factor C, and stores a knowledge model 4a containing the relationship information 24. When acquiring new observation data 32a, the generation unit 36 generates a new conditional probability table 36b and updates the knowledge model 4a stored in the knowledge model storage unit 38.SELECTED DRAWING: Figure 6
【課題】知識モデルを効率よく作成することができる知識モデル作成支援装置を提供する。【解決手段】知識モデル作成支援装置30は、関係性情報24を定義するための対象因子31aとして親因子A,Bおよび子因子Cを取得する対象因子取得部31と、親因子A,Bの因子値および子因子Cの因子値についての観測データ32aを取得する観測データ取得部32と、観測データ32aに基づいて、親因子A,Bの因子値を条件とした場合に子因子Cの因子値に該当する確率が定義された条件付確率表36bを生成する生成部36と、生成された条件付確率表36bを親因子A,Bと子因子Cとの関係性情報24として、関係性情報24を含む知識モデル4aを格納する知識モデル格納部38とを備える。生成部36は、新たな観測データ32aを取得した場合に、新たな条件付確率表36bを生成し、知識モデル格納部38に格納される知識モデル4aを更新する。【選択図】図6 |
