the action history acquisition means acquires a predetermined number of histories in order of closeness of browsing times in histories including user identification information of the different user to the browsing time acquired by the user identification information acquisition means.
5 . The information processing apparatus according to claim 1 , wherein
the user identification information acquisition means acquires user identification information of the different user whose history includes the page identification information included in the transmission request and a browsing time from the history storage means storing the page identification information, the user identification information, and a browsing time of the web page in association with each other, and
the action history acquisition means acquires the history including the browsing time included in a predetermined range of time from the browsing time acquired by the user identification information acquisition means from among the histories including user identification information of the different user.
6 . The information processing apparatus according to claim 1 , wherein
the user identification information acquisition means acquires user identification information of the different user whose history includes the page identification information included in the transmission request and a word from the history storage means storing the page identification information, the user identification information, and a word used when the browsed web page is searched for in association with each other, and
the action history acquisition means acquires the history including the word acquired by the user identification information acquisition means from among the histories including user identification information of the different user.
7 . The information processing apparatus according to claim 1 , wherein
the advertisement determination means determines the advertisement on the basis of the histories acquired by the action history acquisition means when the number acquired by the number acquisition means is smaller than the threshold value and a number of the histories acquired by the action history acquisition means is greater than or equal to a predetermined number.
8 . The information processing apparatus according to claim 1 , wherein
the action history acquisition means acquires the histories including user identification information of different users from the history storage means storing histories including the user identification information and division identification information identifying a division to which a transaction target that is a target of the predetermined action belongs,
the information processing apparatus further includes a calculation means that calculates a degree of tendency to do the predetermined action toward any of one or more divisions indicated by the division identification information included in one or more histories acquired by the action history acquisition means, and
the advertisement determination means determines the advertisement on the basis of the histories acquired by the action history acquisition means when the number acquired by the number acquisition means is smaller than the threshold value and the degree of tendency that is calculated by the calculation means is greater than or equal to a second threshold value.
9 . The information processing apparatus according to claim 8 , further comprising:
a second threshold value determination means that determines the second threshold value such that the smaller a number of the histories acquired by the action history acquisition means is, the smaller the second threshold value is,
wherein the advertisement determination means determines the advertisement on the basis of the histories acquired by the action history acquisition means when the number acquired by the number acquisition means is smaller than the threshold value and the degree of tendency that is calculated by the calculation means is greater than or equal to the second threshold value determined by the second threshold value determination means.
10 . The information processing apparatus according to claim 1 , wherein
the action history acquisition means acquires histories including user identification information of the different users from the history storage means storing histories including the user identification information and division identification information identifying a division to which a transaction target that is a target of the predetermined action belongs,
the information processing apparatus further includes
a calculation means that calculates a degree of tendency to do the predetermined action toward any of one or more divisions indicated by the division identification information included in one or more histories acquired by the action history acquisition means, and
a threshold determination means that determines the threshold value such that the larger the degree of tendency that is calculated by the calculation means is, the larger the threshold value is, and
the advertisement determination means determines the advertisement on the basis of the histories acquired by the action history acquisition means when the number acquired by the number acquisition means is smaller than the threshold value determined by the threshold determination means.
11 . The information processing apparatus according to claim 1 , wherein
the action history acquisition means acquires the history including user identification information of the different user from the history storage means storing the history of a user's action toward a transmitted advertisement.
