DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for acquiring usage data of an application on an information processing apparatus.
In particular, the present invention relates to a method, a device, and a recording medium for acquiring usage data of an application on an information processing device such as a computer in order to apply to usage trend research, Internet media effect measurement, and advertising media value evaluation technology.

[0002]

2. Description of the Related Art In recent years, the W
Network services such as WW and e-mail have also penetrated ordinary households. Along with this, personal computers with a network communication function have spread, and general home appliances such as televisions with a network communication function have been integrated with computers.

[0003] In a server-client type network communication service in which an information server provides a service in accordance with a request from an information terminal, when the use status of the service is to be obtained, a method of recording the information server side at present is the mainstream. It is. Each time an information terminal makes a request to the information server, the content of the provided service, user information,
Usage data such as time is recorded in the corresponding information server.

[0004] On the other hand, the operating system on the information terminal side may have a function of recording the usage status of the service, but the usage data for each application is highly dependent on the application, so that the error data and the like are extremely limited. Only information can be obtained. FIG.
FIG. 3 is an explanatory diagram of a conventional method when an application operating on an information terminal acquires usage data.

[0005] Conventionally, when an application operating on an information terminal acquires usage data, the application shown in FIG.
The three methods of the inter-process communication method, the library replacement method, and the application modification method shown in (3) are adopted. In the inter-process communication method illustrated in FIG. 1A, a plurality of monitoring processes 1 perform data communication with each other via an operating system, and the state of a predetermined application 2 in the predetermined monitoring process 1 is changed by another monitoring process. 1 is a method that can be known.

For example, Microsoft Windows
In the sOS, an inter-process communication method called an OLE method or a DDE method can be realized. When a WWW browser is used as an application, acquiring page address information or the like being displayed by making an inquiry from an external process. Can be. The library replacement method shown in FIG. 1 (2) replaces a library, which is a group of functions called from the application 2a, with a library 2aL having a monitoring function.
In this method, the history of function calls from the application 2a can be known on the library 2aL side.

[0007] For example, Microsoft Windows
sOS Wsock32. dll is replaced with a communication library having a monitoring function with the same name as a communication library having a monitoring function. By this replacement, a history of calling various functions of the library from a WWW browser can be acquired. The application remodeling method shown in FIG. 1 (3) is a method of recording usage data necessary for the application 2b itself in the usage history file 3 by using the remodeled application 2b.

[0008]

However, FIG.
In the case of the conventional inter-process communication method shown in (1), recording and publishing of the use history generally does not directly benefit the user, so that it is difficult to implement the function as an original function of the application and only obtain limited data. There is a problem that it is often impossible.

In the case of the conventional application modification system shown in FIG. 1 (3) or the conventional library replacement system shown in FIG. 1 (2), modification must be made for each application or library. There is no problem. In addition, since a modification must be made for each application or library and then redistributed, a large cost is required.

FIG. 2 is a block diagram showing an information processing apparatus 101 for acquiring application use data according to a first embodiment of the present invention. This figure also
4 shows a state (initial processing) at the time of starting an application in the information processing apparatus 101. In this embodiment, the information processing apparatus 101 is, for example, a personal computer PC1. An application in the information processing apparatus 101 acquires usage data. Monitoring process 10 resident in information processing apparatus 101
However, when the application 20 to be monitored is started,
Issue an instruction to load the monitoring dedicated library 20L,
In response to this command, the application 20 loads the monitoring-only library 20L.

FIG. 3 is a block diagram showing a state (monitoring state) of the information processing apparatus 101 when an application is executed. The monitoring-dedicated library 20L transmits event information (information such as contents of provided services, user information, time, etc.) necessary for collecting usage data among events generated in the operating system OS between the application 20 and the operating system OS. , Interrupt,
It is acquired in a form intercepted (between the application 20 and the operating system OS) on the way, and the event is selected based on the application-specific processing described later, and the selected event is interpreted. The information is transmitted to the sequential monitoring process 10. The monitoring process 10 creates usage data based on the acquired event information, and saves the created usage data in the usage history file 30.

Here, the application-specific processing will be described. 1 that can be used to monitor 20L
There are various types of next information (event information). For example, if it is a WWW browser application,
As an event between the S-browser, for example, (event name) (meaning) WM_COMMAND {pressing a button on the browser WM_DDE_EXECUTE} ... instruction from another application WM_KEYDOWN {input from keyboard WM_SETTEXT}多数 A lot of information such as changes in character strings such as file addresses can be obtained.

However, since the data to be used is only a part of the data, information for selecting the data is required, and a process of converting the information into data required as the usage data is required. become. This is called application-specific processing. For example, among the above, when only the file address is necessary as the use data, a procedure of “extracting only the WM_SETTEXT event from a large number of events, extracting its argument, and recording it as a file address” is application-specific processing. .

Note that instead of interrupting between the application 20 and the operating system OS to acquire event information (referred to as a first method), instead of interrupting between the application 20 and the library 25, interception is performed on the way. May be used to acquire event information (referred to as a second method). These methods will be described with reference to FIG.

The first method is represented by steps A1 and A2. In step A1, event information generated by the operating system OS is stored in the monitoring-only library 20L.
Then, the event information is passed to the application 20 as step A2. The second method is a method represented by steps B1 and B2. By rewriting the first few bytes of a function such as the send function in the library 25 (step B1), the processing is jumped to the monitoring-dedicated library (step B2).
The monitoring-dedicated library acquires the arguments of functions such as the nd function.

In the library 25 shown in FIG. 3, various functions necessary for the operation of the application are shared as functions, and are stored in a file separate from the application. Therefore, the functions are not particularly limited. All of the basic processing such as reading and writing of files, transmission and reception via a network, and various screen displays is realized by the library 25.

The target of the embodiment is wsock
32. dll is a library for network communication. This library contains functions for data communication on the Internet. Email, WW
Most Internet applications, such as W browsers and file transfers, use this library. As a function, send @ send data to the destination computer recv @ receive data from the destination computer gethostname ... find the destination computer connect @ create a connection state, etc. , About 50 types are included.

FIG. 5 is a block diagram showing an information processing apparatus 102 according to a second embodiment of the present invention, and shows a state (monitoring state) when a plurality of applications are executed. The information processing apparatus 102 is configured by, for example, a personal computer PC2. As shown in the figure, one monitoring process 1
0 monitors a plurality of applications 21, 22, and 23, the monitoring dedicated libraries 21 L, 22 L, and 23 L inserted in each application 21 to 23 use the usage data generated by the applications 21 to 23 in one monitoring process. Consolidate to 10.

Next, the above-described embodiment will be described by taking as an example a case where a WWW browser is used as an application. WWW browser is a WW on the Internet
An application that obtains information stored in the W server through a network and browses the obtained information. In this case, the unit of information to be browsed is a page, and the “page” is a set of information mainly composed of one or more elements described in the HTML language. Each element constituting the above information set is provided with an address indicating a position in an information space called a URL.

A user uses a WWW browser to access a URL
You can view information by using and specifying the desired page. In addition, pages can be associated with each other by hyperlinks, and when a user presses a hyperlink displayed on the page, related information can be traced one after another. WWW is a service of a server client system, and the basic operation at the time of referring to a page is as follows.

(1) A request is sent from a browser as a client to a server. (2) The server receives the request from the client,
A page corresponding to this request is sent back as a response. (3) The browser receives the response and displays it on the screen.
This series of transmission / reception procedures is defined as the HTTP protocol.
