Abstract

PROBLEM TO BE SOLVED: To digitize the liking of a user who accesses a home page on the Internet by weighting access times and a stay time within a prescribed period to permit the strength of a preference degree to be larger in a later access and calculating the intensity of the preference degree. SOLUTION: The access date and time and the stay time in a home page are stored in a home page history data storage part 1 by a client (user) 11 with the Internet. A home page liking degree digitizing part 2 calculates the strength of the liking degree of the home page as a numerical value by weighting the access times and the stay time within the prescribed period, so as to permit the intensity of the preference degree to be larger in the later access based on the access time and date and the stay time which are stored in the home page history data storage part 1. Moreover, the home page preference degree digitizing part 2 is connected to the Internet 12 via a modem 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a homepage preference evaluation apparatus for quantifying a user's preference for a homepage on the Internet in order to make a man-machine interface of an Internet device intelligent.

[0002]

2. Description of the Related Art Generally, a homepage address (UR) is used as history data of a user visiting a homepage on the Internet by using history file data of a browser.
L: Uniform Resource Locator), the date and time of visit, the expiration date of history data, and the date and time of update of the homepage. As this type of browser, Microsoft Internet Explorer and Netscape Navigator are known.
Conventionally, these pieces of history data can be displayed in alphabetical order of URL, in ascending order of date and time, and in descending order of date and time.

[0003]

However, in the above-mentioned conventional example, the history data is displayed in alphabetical order of URL, in ascending order of date and time, and in descending order of date and time. There is a problem that can not be.

The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to provide a homepage preference evaluation device capable of quantifying the preference of a user who has visited a homepage on the Internet.

[0005]

According to the present invention, in order to achieve the above object, the number of visits to a homepage and the length of stay are weighted such that the more recent visits, the greater the degree of preference. is there. That is, according to the present invention,
A storage unit for storing a visit date and time and a stay time of visiting the homepage; and, based on the visit date and time and the stay time stored in the storage unit, the number of visits and the stay time within a predetermined period are set so that the more recent visits have a preference. There is provided a homepage preference evaluation apparatus having a homepage preference degree quantifying means for calculating the degree of preference of the homepage as a numerical value by weighting the degree of the degree so as to increase the degree of the degree.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a homepage preference evaluation device according to the present invention, FIG. 2 is an explanatory diagram showing a PAD of the homepage preference evaluation device of FIG.
FIG. 3 is an explanatory diagram showing the homepage process of FIG. 2 in detail, and FIG. 4 is an explanatory diagram showing the visit date process of FIG. 3 in detail.

[0007] In FIG. 1, a homepage history data storage unit 1 stores a visit date and a stay time when a client (user) 11 visits a homepage via the Internet 12. As shown in FIGS. 2 to 4, the homepage preference degree quantification unit 2 calculates the number of visits and the stay time within a predetermined period based on the visit date and time and the stay time stored in the homepage history data storage unit. The degree of preference of the homepage is calculated as a numerical value by weighting so that the degree of preference increases with the visit.
The homepage preference degree quantification unit 2 is connected to the Internet 12 via the modem 3.

FIG. 2 shows a process of calculating the user's preference level Fp for the home page of the page number p indicated by the URL. First, initialization is performed (step S1), and then a homepage process shown in detail in FIG. 3 is performed on the pth homepage to calculate a preference degree Fp of the page number p (step S2 → S3). Next, the preference degrees Fp are sorted in ascending or descending order (step S
4) Then, this preference level Fp is output (step S).
5).

In the homepage process in step S3, by executing a visit date process shown in detail in FIG.
M) The strength of preference ftp as viewed from the stay time (total visit time) tmp for the page number p on the day, and the total number of visits Nmp
Of the preference fNp viewed from the user (steps S11 to S11)
S13). The day may be from 00:00 to 24:00,
From 6:00 on the day to 6:00 on the following day, the day may be determined in advance so that one day is 24 hours in accordance with the usage form of the Internet. Next, ftp and fNp for M days are respectively added to calculate Ftp and FNp (step S14), and then the magnitude of Ftp and FNp is determined (step S15), and the larger one is determined as the preference degree Fp of the page number p. (Steps S16 and S17).

In the visit date processing in step S13,
As shown in detail in FIG. 4, the n-th stay start time is set to Tsnmp
The stay end time is Tenmp, and the stay time (visit time) tnmp tnmp = Tenmp−Tsnmp is calculated (step S21 → S22), and then,
That is, the total visit time tmp of the total number of visits Nmp on the m-th day is calculated (step S23). Next, in the preference calculation period (M days), the total visit time tmp and the total number of visits Nmp are multiplied by weights as follows, so that the more recent visits have a greater effect on the preference, as described below. By this, the strength f of the preference as viewed from the total visit time tmp of each day f
tp and the strength fNp of the preference viewed from the total number of visits Nmp of each day are calculated. ftp (m) = α · W (m) · tmp fNp (m) = W (m) · Nmp

Here, assuming that the weighting function for the number of elapsed days m is W (m), and that the strength of the preference is directly proportional to the numerical value, the function W (m) increases with the number of elapsed days m. Α is a strength fNp of the preference viewed from the total number of visits Nmp of each day, and is a coefficient for normalizing the strength ftp of the preference viewed from the total visit time tmp.

Therefore, the number of visits and the staying time are weighted so that the degree of preference increases as the number of visits increases, and M days are added, and the preference of a user who has visited a homepage on the Internet is quantified. In addition, a temporary visit can be deleted to display a page with a large number of visits and a page with a long stay time even with a single visit.

[0013]

As described above, according to the present invention, the number of visits to the homepage and the staying time are weighted so that the more recent visits, the greater the degree of preference becomes. Can be converted into numerical values of the user's preferences.
