Or, get screen capture information.

(Calculation unit 133)
The calculation unit 133 calculates the difference between the link destination information acquired by the first acquisition unit 131 and the link destination information acquired by the second acquisition unit 132. For example, the calculation unit 133 calculates the difference based on the plurality of elements of the link destination information acquired by the first acquisition unit 131 and the plurality of elements of the link destination information acquired by the second acquisition unit 132. To do. The calculated difference may be the edit distance between the link destination information acquired by the first acquisition unit 131 and the link destination information acquired by the second acquisition unit 132. Taking the example shown in FIG. 1, the calculation unit 133 calculates the difference between the information shown by the image IM21 and the information shown by the image IM31, for example. In this case, the calculation unit 133 calculates the difference between the image IM21 and the image IM31 having information such as “vegetable juice renders carcinogens harmless”.

For example, the calculation unit 133 calculates the difference as a plurality of elements based on the change in the site capacity of the information of the link destination. Specifically, the calculation unit 133 calculates the difference based on the image capacity of the site capacity as a plurality of elements. Further, the calculation unit 133 calculates the difference as a plurality of elements based on the change in the number of images.

Here, the case where the predetermined condition is not satisfied indicates, for example, the case where the difference is within a predetermined range. The difference based on the predetermined order may be accumulated stepwise for each predetermined order, or may be reset for each predetermined order.

Here, a specific example in which the differences based on a predetermined order are accumulated step by step in a predetermined order will be described. For example, the upper limit within a predetermined range is 100. For example, when the difference due to the change in site capacity is calculated to be 30, the calculating unit 133 calculates the difference in HTML information because it is within the predetermined range. For example, when the difference due to the change in the HTML information is calculated as 50, the calculation unit 133 is within the predetermined range because the sum of the difference with the site capacity is 80. Then, the calculation unit 133 calculates the difference of the screen capture information. For example, when the difference due to the change in the screen capture information is calculated as 40, the calculation unit 133 exceeds 120, because the total of the difference based on the site capacity and the difference based on the HTML information is 120.

For example, the calculation unit 133 calculates the difference based on the inner product of the plurality of elements and the weight set for each of the plurality of elements. For example, the calculation unit 133 forms a model as shown in (1) below based on the plurality of elements x _{1 to} x _n and the corresponding weights w _{1 to} w _n of the plurality of elements to calculate the difference. Good.

y=w ₁ *x ₁ +w ₂ *x ₂ +・・・+w _n *x _n +b (1)

Here, the weight for each of the plurality of elements may be set based on the learning result. For example, when the calculation unit 133 learns that the difference based on the site capacity is more important for identifying the submission information than the difference based on the screen capture information, the calculation unit 133 sets the value of the element weight based on the site capacity. , May be larger than the value of the element weight based on the screen capture information.
