The content creation system comprises: an operation measurement devicethat acquires, as measurement information, a three-dimensional work operation of a model worker Rthat performs the work of the work procedure; an evaluation criterion creation devicethat creates evaluation criterion information on the work of the work procedure, based on the measurement information of the three-dimensional work operation; and a content creation devicethat creates and updates the training content, based on the measurement information of the three-dimensional work operation, the evaluation criterion information and the three-dimensional shape information of the work target device. The work management servercreates the evaluation criterion information, based on distance information of the three-dimensional work operation with respect to the three-dimensional shape in specific stage of the work procedure, on the condition that a predetermined body motion of the model worker Ris detected.

Content creation system

A content presentation system includes: a trainee terminal that presents training content to the trainee; a worker terminal used by a worker; a tool recognition device that acquires a work video of the worker and recognizes the tool being used by the worker; a determination device that determines success or failure of the work at a specific stage based on the information about the work tool recognized by the tool recognition device; and a content creation device that creates and updates the training content based on the determination result of the determination device. When the determination result is determined to be the failure of the work by the determination device, the content creation device identifies a portion of the training content corresponding to the specific stage in the work procedure and updates the portion of the training content so as to suppress a factor of the failure.

Content presentation system and content presentation method

A content presentation system includes: a training content distribution functionthat presents the training content to the trainee; a work content delivery functionthat presents a work procedure based on augmented reality; a user operation detection unitthat detects a three-dimensional operation of the site worker; a work record analysis functionthat determines success or failure of the work based on the evaluation reference information; and a content creation/updating functionthat updates the training content based on the determination result. When a predetermined body motion of the worker is detected, the work record analysis function determines whether the work has failed based on the measurement information of the model worker up to the body motion. When the work is determined to have failed, the content creation/updating function updates the training content so as to suppress the factor of the failure.

An analysis apparatus is connectable to a terminal capable of displaying web pages by accessing a web server capable of executing a web application. The analysis apparatus comprises a processor, a memory and an interface. The processor is configured to perform the following processing of: receiving at least one log concerning the web application stored in the terminal from the terminal via the interface; acquiring a plurality of kinds of use condition feature values based on the log received, the plurality of kinds of use condition feature values being information characterizing conditions of use of the web application; analyzing whether a correlation exists between a first kind of use condition feature values and a second kind of use condition feature values in the plurality of kinds of use condition feature values acquired in the processing of acquiring; and outputting an analysis result obtained by the processing of the analyzing.

Collecting log data efficiently by controlling the capturing event for an operation log on the basis of application layer information. A web server generates a response including an operation log capturing script and the information from an operation log capturing control definition table and a property capturing definition table, and sends the response to a client. In the client, the received information is forwarded from a web browser module to a script engine module. An operation log capturing module sets the information acquisition event handler on the basis of the forwarded information, captures a sequential operation log on the basis of the operations performed by a user in the web browser, and sends the captured sequential operation log to a log server. A log server module collects sequential operation log in an operation log table, and a log analysis module analyzes the collected logs.

Model data is generated from performance information sorted by day of the week, time period, and process status by a performance information analysis section and a process status analysis section. An abnormality determination section detects abnormality using appropriate model data. What the graph of an expected status is like, how much the graph of the current status that has been determined abnormal differs from the graph of the expected status, and how much the current status is like the expected status are displayed allowing a system manager to observe detailed information about abnormality determination.

Abnormality detection method, device and program

The single sign-on is implemented without requiring knowledge of a lower layer such as HTTP and HTML by using a single sign-on module which stores knowledge to store single sign-on and a single sign-on server which analyzes log-in communication of an EIS (Enterprise Information System) and selects and executes an applicable single sign-on module. Since the single sign-on can be implemented without requiring knowledge of a lower layer such as HTTP and HTML from a system engineer, the single sign-on can be implemented in a short period and at low cost.

System and method for single sign-on

The search method comprises a first step of receiving a service inquiry request; a second step of making an inquiry about policy information of a clientwho requested service and obtaining the policy information of the clientfrom a policy database; a third step of sending a request to search for a server matching the service sought after by the request and obtaining information showing the server matching the service from a registry; a fourth step of extracting a server meeting the policy information of the client obtained in the second step out of servers related to the information obtained in the third step; and a fifth step of transmitting information showing the server extracted in the fourth step to the source of the request to search for service.

In a computer system including a plurality of computers interconnected through a network, a specific computer A in the computer system manages the computer resource information and the operating condition information such as for a CPU, a file and a memory and the user resource information such as file data and a program of each computer of the computer system. When a user issues a request from a computer C to log in to the computer system, the request is reported to the computer A, and the information related to the user is returned to the computer C with reference to the user resource information held by the computer A. Then, the computer C acquires the file and the usable program held by the user in the computer system and executes a process, whereby the whole system can be used as resources of each user.

Each of a plurality of simulation programs is linked with a data conversion library and is executed as a simulation process. A data conversion process is executed in correspondence with each simulation process. In exchanging data resulted from simulation by the simulation process of one of the simulation programs with simulation processes of the other simulation programs, the data conversion process provided for a sending simulation process determines a receiving simulation process to which the data is to be sent, and sends the data to the data conversion process corresponding to the receiving simulation process. The data conversion process for the receiving simulation process performs data conversion for absorbing difference between the base of the sending simulation process and the base of the receiving simulation process, and transfers the data after the conversion to the receiving simulation process.
