Abstract: A work support apparatus includes a line and point detection unit that acquires drawing data in which a circuit indicating a connection relationship between devices is described by a character, a line, and a point, and detects the line and point based on the drawing data. A drawing sign detection unit detects a drawing sign constituting the circuit. The wiring detection unit detects a wiring connecting the drawing signs based on information on the line and point. The character detection unit detects the character. The circuit connection information generation unit generates circuit connection information. Since the circuit connection information in the same page and over pages of the drawing data is generated, the terminal component detection unit detects, as a terminal component, a wiring or first drawing sign that is not connected to a second drawing sign at least at one end.

Abstract: Provided is a technique capable of setting an appropriate link destination when there are a plurality of link destination candidates among data files. A file management system according to the present invention determines a type of a target indicated by a character string described in a data file to determine whether the target matches among data files and assigns a link among the data files when the target matches.

Abstract: A work assistance system includes a drawing, a work record table, a handwriting display determination unit, a display control unit, and input means. The drawing includes parts and handwritings. The work record table stores the handwriting for the part as the work record. The handwriting display determination unit determines, as the writing candidates, the handwritings not associated with the parts based on the work record table. The display control unit displays the writing candidates and the parts via the input means in a selectable manner on a data display unit of a terminal of a user.

Abstract: Provided is a work record extraction device that can correctly select a drawing element corresponding to handwriting even if there is a handwriting deviation when position coordinates are collated between handwritten data overwritten on drawing data by manual input and a drawing element on the drawing data. The work record extraction device according to the invention sets, around a drawing element, a boundary area including at least a part of the drawing element, determines whether handwritten data passes through at least a part of the boundary area, and determines that the handwritten data passes through the drawing element in a case where the handwritten data passes through at least a part of the boundary area.
