[Problem] To implement a work
management system that is capable of recording work results in
time series, and that is easy to introduce and can accommodate a wide range of work patterns to be managed. [Solution] The present invention is characterized by involving: a location
information transmission terminal that transmits location information of a location where work is being performed by a working entity; a log
information storage unit that receives the location information transmitted by the location
information transmission terminal, and stores the location information in
time series as log information associated with a transmission source identifier, which identifies the transmission source, and information indicating a time; and an
information analysis unit that determines the time-series
work content of the working entity by determining the work section for the location information recorded in
time series in the log information, on the basis of work area attribute information in which work section information is associated with section attribute information indicating the attributes of the work section, the work section information indicating the area of the location where the work is performed in association with the location information transmitted by the location
information transmission terminal. The present invention is also characterized in that the
information analysis unit refers to work detail determination information in which information indicating characteristics of the
movement pattern of the working entity is associated with information indicating
work content, and determines the content of the work on the basis of characteristics of the trajectory indicated by the location information.
