  Here, as the first external system 20a, Yahoo! The Japanese morphological analysis API (http://api.jlp.yahoo.co.jp/MAService/V1/parse) is used. The content management system 10 transmits “appid = application ID, result = ma, sentence =“ API business ”to this API (external system 20a) by the POST method. The result is Yahoo! Returned from the API of Japanese morphological analysis, the return value is passed to the second external system 20b. In the external system 20b, Yahoo! An XML file that is a return value from the Japanese morphological analysis API is analyzed, a word (“API”) first determined as a noun is extracted, and the result is returned to the content management system 10. Next, as the third external system 20c, Yahoo! The search result of the word “API” is acquired using the search API.

  Thereafter, the content management system 10 processes the return value from the external system 20 c using a definition file or the like recorded in advance, and transmits the generated information to the user terminal device 30. In this example, the result is the same as in Example 1.

  Further, in the example of FIG. 10, a case has been described in which the return value acquired from one external system 20 or information obtained by processing the return value is used to further acquire information from another external system 20. As shown in FIG. 11, the return value obtained from any M external systems 20a,..., 20m or information obtained by processing the return value is passed to the same or another external system 20n, Information may be further acquired from the external system 20n.

  Further, by combining the present embodiment and the second embodiment, a return value acquired from any P external systems 20 or information obtained by processing return values is passed to any Q external systems 20, and this Further information may be acquired from Q external systems 20.

  By the way, a return value from an arbitrary external system 20 is obtained by using an identifier “Z” that uniquely identifies the external system 20 on the network N, and “%% API-Z: XML: element 1. The return value from the external system 20 may be extracted by a naming rule using the identifier of the external system 20 such as “element 2.... Element Z %% in the element Z-1”. The return value extracted in this way can be applied to calls to the same or another external system 20.

  For example, the value of the element AMOUNT is extracted by the external system 20a with the identifier “1” (ID = 1), and the API of the external system 20b with the identifier “2” (ID = 2) (for example, http: // gaibuapi. The case where the external system 20b operates normally when “mount” is passed to the GET parameter for jp / api) will be described.

  In this case, the return value from the external system 20a with the identifier “1” is extracted as “%% API-1: XML: AMOUNT %%”. At this time, when the value of the element AMOUNT acquired as the return value from the external system 20a is passed to the external system 20b with the identifier “2”, the parameter “amount = %% API−” is sent to the API call interface of the external system 20b. 1: XML: AMOUNT %% ", for example, by calling" http://gaibuapi.jp/api?amount=%%API-1:XML:AMOUNT%% " Is possible.
