The operation of the recipe providing system configured as described above will be described. In the description, reference numerals in FIGS. 1 to 10 are referred to.
FIG. 11 is a flowchart showing an outline of data processing of the host system 2.
The processing is started by the activation of the host system 2, and it is determined whether or not the current time is the blog search time (or time zone) (step 1101).
If the current time is the blog search time, a transmission request for the blog data 36 is made from the host system 2 to the blog management system 5 (step 1102), and the host system 2 receives the blog data 36 from the blog management system 5. (Step 1103).
It is determined from the received blog data 36 whether or not the blog has been updated (step 1104). If there is an update, the updated portion of the blog data 36 is registered in the blog / tweet storage database 9 (step 1105), and personal situation analysis processing is performed based on the updated portion of the blog data 36 (step 1106). Thereafter, the process returns to the determination of whether or not it is the blog search time (step 1101).

  If the blog is not updated in step 1104, the process returns to the determination of whether or not it is the blog search time (step 1101). For example, whether or not a blog is updated can be confirmed by receiving feed data such as RSS (RDF Site Summary).

  If it is determined in step 1101 that the current time is not the blog search time, it is determined whether it is a recipe provision time (or time zone) (step 1107). If it is the recipe provision time, search keyword extraction processing is performed (step 1108), menu recipe search processing is performed (step 1109), and transmission / reception processing for transmitting the menu recipe data 44 to the mobile terminal device 3 is performed (step 1110). Thereafter, the process returns to the determination of whether or not it is the blog search time (step 1101).

  If the current time is not the recipe provision time, it is determined whether or not the menu recipe response data has been received (step 1111), and if received, the transmission / reception processing is performed in accordance with the menu recipe response data (step 1110), The process returns to the determination of whether or not it is the blog search time (step 1101). If the menu recipe response data has not been received, the process returns to the determination of whether or not it is the blog search time (step 1101).

For example, if the title 53 is “going out” and the text 54 is “going to Nihonbashi”, “Nihonbashi” is the extracted word. Further, the process determines whether “Nihonbashi” is registered in the extracted keyword 21 of the personal interest situation database 1.

  If the extracted word does not exist in the registered extracted keyword 21, the registered word is added as the extracted keyword 21 of the personal interest situation database 1, the registration date 22 is added, and the interest level 23 is set to "1". (Step 1204). When the extracted word exists in the registered extracted keyword 21, the registration date 22 of the extracted keyword 21 is updated, and +1 is added to the interest level 23 to be updated. (Step 1205). For example, if “Nipponbashi” does not exist in the extracted keyword 21, it is newly registered. “Nihonbashi” is registered in the extracted keyword 21, the current date is registered in the registration date 22, and “1” is registered in the degree of interest. At this time, the ingredient keyword 24 remains blank.

  Next, one sentence including the extracted word is extracted from the acquired blog data (step 1206), and it is determined whether or not the interest keyword 81 in the interest keyword analysis database 12 is included in one sentence (step 1207). ). If it is included, the addition value 82 corresponding to the interest keyword 81 in the interest keyword analysis database 12 is added to the interest level 23 in the personal interest situation database 1 (step 1208).

  Further, it is determined whether or not the extracted word exists in the ingredient keyword analysis database 11 (step 1209). If it exists, the ingredient keyword 73 is registered in the ingredient keyword 24 of the personal interest situation database 1 (step 1210). ), The process ends. If it does not exist, the data having the extracted word as the extracted keyword 21 is deleted from the personal interest situation database 1 (step 1211), and the process ends.
