摘要
PROBLEM TO BE SOLVED: To accurately recognize a logical relation between item names of a document and a logical relation between the item name and an item value, when a lateral table, a longitudinal table, an orthogonal table or an orthogonal table having a nest structure is included in the document.SOLUTION: A logical relation recognition device 10 extracts item name nodes, and classifies a table into any one of a longitudinal table, a lateral table and an orthogonal table. The logical relation recognition device 10 acquires a logical relation in a longitudinal direction and a lateral direction in an orthogonal table. The logical relation recognition device 10 acquires a logical relation in the longitudinal direction in the longitudinal table. The logical relation recognition device 10 acquires a logical relation in the lateral direction in the lateral table. The logical relation recognition device 10 outputs data of a tree structure obtained by synthesizing the acquired logical relation.SELECTED DRAWING: Figure 5
