Abstract
Provided is an information system and an information collection method that are capable of acquiring desired site data while preventing an increase in cost. A link logic definition unit 17 holds a link logic that is definition information defining a correspondence relation between an item value of the site data and a reference value that is an external value of transaction data used for acquiring the item value. A link logic data acquisition unit 18 acquires the item value of the site data by using the link logic.
Claims8
An information system for acquiring an item value that is a value of site data based on an external value that is a value of external data, the information system comprising:
- a processor;
- and
- a memory coupled to the processor, the memory storing instructions that when executed by the processor configures the processor to:
- store a link logic model that is definition information defining a correspondence relation between the item value and a reference value that is the external value used for acquiring the item value, and
- obtain a search node and a search item to be searched from stored task information, among the site data, to search for,
- for each search item in the site data, determine whether the link logic model is necessary for acquiring the item value based on the external value,
- upon determining the link logic model is not necessary, acquire the item value from the search item,
- upon determining the link logic model is necessary,
- obtain a link logic parameter of the search item,
- create a correspondence relation table between parameters and values of the site data corresponding to the parameters,
- acquire the link logic model,
- based on the correspondence relation table, assign values of the parameters to create link logic based on the link logic model, and
- acquire the item value of the site data based on the link logic.
An information collection method performed by an information system for acquiring an item value that is a value of site data based on an external value that is a value of external data, the information collection method comprising:
- holding a link logic model that is definition information defining a correspondence relation between the item value and a reference value that is the external value used for acquiring the item value;
- obtaining a search node and a search item to be searched from stored task information, among the site data, to search for;
- for each search item in the site data, determining whether the link logic model is necessary for acquiring the item value based on the external value;
- upon determining the link logic model is not necessary
- acquiring the item value from the search item;
- upon determining the link logic model is necessary:
- obtaining a link logic parameter of the search item;
- creating a correspondence relation table between parameters and values of the site data corresponding to the parameters;
- acquiring the link logic model;
- based on the correspondence relation table, assigning values of the parameters to create link logic based on the link logic model, and
- acquiring the item value of the site data based on the link logic.
