Abstract: An information processing system includes: a document reception unit configured to receive multiple pieces of document data; a data storage unit configured to store the received multiple pieces of document data; and a correspondence relation estimation unit configured to estimate a correspondence relation at least between an item in a first document data and an item in a second document data out of the multiple pieces of document data stored in the data storage unit. The correspondence relation estimation unit includes an item-item coupling relation extraction unit configured to extract a coupling relation among items in the first document data and a coupling relation among items in the second document data, and a word relationship extraction unit configured to extract a relevance between a word that appears in an item in the first document data and a word that appears in an item in the second document data.

Abstract: A traceability system includes: a Equipment table that stores production data of a product manufactured in a first process, in which an individual ID is appended to a product; a Equipment table that stores production data of a product manufactured in a second process, in which an individual ID is not appended to a product; a training data setting unit that creates a training data table that stores the Equipment table and the Equipment table, which are correlated with each other; a feature amount extracting unit that calculates a cycle time of a predetermined number of products manufactured in the past in the first process; a model creation section that creates a production time estimation model for estimating a production time at which a product has been manufactured in the second process on the basis of the cycle time of the products; and a production time estimating unit.

Abstract: The information processing apparatus includes a preprocessing unit that allocates the identifier to one or more collected groups, the main storage unit including a buffer having a size of the predetermined unit installed for each group, the storage unit that stores the data written in the buffer for each predetermined unit and each group, a write processing unit that acquires the data allocated to the group for each group and writes the acquired data in the buffer, determines whether or not the data of the predetermined unit has been written in the buffer, and causes the storage unit to store the data written in the buffer when the data of the predetermined unit is determined to have been written in the buffer, and a read processing unit that reads the stored data out to the main storage unit for each group, extracts the read data, and executes the process.
