An information collection and display system is provided, in which a data generation device that generates site data and a transaction data accumulation unit that stores the site data are connected. The system includes an association data accumulation unit storing association data which defines an association of each of multiple pieces of information included in the site data; an association data search unit which searches for second information associated with first information included in the pieces of information, on the basis of the association data; and a user interface that displays a connection relation of the pieces of information associated by the association data. The association data search unit searches for the second information associated with the first information displayed on the user interface and displays the first information and the second information on the user interface with the connection relation of the pieces of information.

Information collection and display system, information collection method, and information display method

A data analysis device executes: acquiring time-series data including data of multiple items from an analysis target system; extracting data of at least, one first item from the time series data; calculating a feature of a temporal change of the data of the first item; extracting data of at least one second item from the time series data; calculating a feature of at least one of a relevance between the data of the first item and the data of the second item and a relevance between the data of the multiple second items; determining a model corresponding to the analysis target system on the basis of the feature of the temporal change and the change of the relevance; and setting the parameter in the analysis target system by using the parameter setting configuration of the model.

Parameter setting method, data analysis device and data analysis system

The method includes: identifying a type of a data item in which the data is stored, using an overlap pattern indicating the type of the data item and a method for identifying the type; processing the data stored in the data item, using calculation designated for each type of the data item, and adding at least one or more new data items to the type of the data item storing the processed data; and calculating scores obtained by quantifying an amount of information displayed on a display screen for the data items including the added data items and arranging the data items on the basis of the scores.

Data processing method, data processing device, and recording medium

A trial number and a failure number of a procedure extending to the plurality of devices configuring the mobile core network are acquired, a process trial number and a failure number of a received message in the single device are acquired, and the possibility of quality degradation of the devices configuring the mobile core network is calculated on the basis of the trial number and the failure numbers.
