Description:
BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    The present invention relates to an information browse supporting method and system, and to a program for a computer to execute the information browse supporting method. The present disclosure also relates to subject matter contained in Japanese Patent application No. 2001-160019 (filed on May 29, 2001), which is expressly incorporated herein by reference in its entirety.  
           [0003]    2. Description of the Related Art  
           [0004]    Over the recent years, there have been a great number of enterprises scheming to increase an efficiency of office operations and to enhance a productivity by utilizing software (that is generally known as groupware) for enabling the operations (works) to advance in such a form that a plurality of persons share the information by use of the Internet and in-office LAN. Further, there increase needs for browsing only necessary items of information from a tremendous quantity of information opened to the public on the Internet. For example, as in the case of the clipping service for distributing news concerning the fields registered beforehand and news containing the keywords registered, a service for providing only necessary items of information to the individual (which is generally known as the personalization service) has already come into a practical stage. Moreover, there exist a great number of Web sites on which to provide a service for notifying requesters of fresh pieces of information by E-mails.  
           [0005]    The technology is easy to utilize the formation of a variety of categories and, while on the other hand, has a problem that the information to be obtained has a bias to limited categories. Further, the technology described above does not implement a function of providing a sort of care-for-others information showing mutual concerns about (psychological and physical) conditions as, e.g., family members do.  
           [0006]    Accordingly, it is a primary object of the present invention, which was devised under such circumstances, to provide an information browse supporting method and system utilized for a plurality of users to browse the information and capable of vitalizing user-to-user communications.  
           [0007]    It is another object of the present invention to provide a program executed by a computer to function as an information browse supporting system.  
         SUMMARY OF THE INVENTION  
         [0008]    To accomplish the above objects, according to one aspect of the present invention, an information browse supporting method comprises a first search condition information setting step of setting a condition, inputted by any one of a plurality of users, for searching for information suited to this user, as first search condition information on this user, a second search condition information setting step of setting a condition, inputted by any one of the plurality of users in a way that specifies other user, for searching information suited to this other user, as second search condition information on this other user on this other user, an information searching step of searching, from within browsing target information containing a plurality of information elements, for an information element with respect to a certain user in accordance with the first search condition information set in the first search condition information setting step and the second search condition information set in the second search condition information setting step, and an information presenting step of presenting to a certain user a piece of information corresponding to a searched result with respect to a certain user in the information searching step.  
           [0009]    Namely, according to the information browse supporting system of the present invention, for example, supposing that the plurality users are users A, B and C, the search for the information with respect to the user A in the information searching step, involves the use of the first search condition information set as a result of inputting the information by the user A, the second search condition information set as a result of inputting the information by the user B, and the second search condition information set as a result of inputting the information by the user C. Then, the information corresponding to the searched result in the information-searching step is presented to the user A in the information-presenting step.  
           [0010]    Thus, according to the information browse supporting system of the present invention, an intention of other user (which is coincident with a content of the information inputted by other user in a way that specifies a certain user in the second search condition information setting step), can be reflected in the information presented to a certain user. Accordingly, the use of the present information browse supporting system enables each user to indirectly recognize that other user shows a kind care for the user himself or herself by browsing the information presented to the same user. As a consequence, the user-to-user communications can be vitalized.  
           [0011]    Further, when carrying out the information browse supporting method of the present invention, the second search condition information setting step may involve setting the information inputted in such a form that any one of the plurality of users specifies other user as the second search condition information on the other user together with setting user information indicating the user who inputted the information, and the information presenting step may involve presenting to a user pieces of information on the respective information elements searched with respect to this user, and presenting a piece of information indicating a setting user of the second search condition information on the basis of the setting user information set together with the second search condition information in the second search condition information setting step with respect to the information elements searched by the second search condition information. According to the present information browse supporting system, it is feasible to actualize a platform (environment) where each user browses the information in a way of recognizing that some other user has a kind concern about this browsing user.  
           [0012]    Note that the browsing target information processed by the information browse supporting method of the present invention may be any categories of information on condition that it contains a plurality of information elements, and the information present in the information presenting step may be any categories of information on condition that it corresponds to the searched result in the information searching step. Namely, the browsing target information may be set as a group of information elements transmitted via the Internet and also as a group of information elements on broadcasting. Moreover, the information presenting step may involve presenting only the information elements searched in the information searching step and presenting the information containing both of the information representing the information elements searched in the information searching step and the browsing target information.  
           [0013]    According to the information browse supporting method of the present invention, the information-presenting step may start operating upon an indication of the user and may also start operating based on the specified schedule. Moreover, the information-searching step may operate just before the information-presenting step operates. The information presenting step and the information searching step may operate at timings independent of each other (for instance, when changing the first and second search condition information, and when changing the contents of the browsing target information, the information searching step may function, and the information presenting step may function when an indication is given from the user).  
           [0014]    Moreover, according to the information browse supporting method of the present invention, the first and second search condition information setting steps may operate based on the information inputted to an input device and may operate based on the information inputted via communication media as on the Internet and so forth. Similarly, the information-presenting step may present the information by outputting the information to an information output device such as a display device etc., and may present the information to the user.  
           [0015]    The information browse supporting method of the present invention may further comprise a second information searching step of searching, based on the second search condition information set by a certain user with respect to other user in the second search condition information setting step, for an information element suited to this other user from the browsing target information, and checking whether or not the thus searched information element is searched by the first search condition information set in the first search condition information setting step with respect to the other user, and a second information presenting step of presenting to a certain user a piece of information corresponding to a searched result and a checked result with respect to a certain user in the second information searching step.  
           [0016]    According to this method, the user who sets the second search condition information with respect to a certain user can communicate with a certain user on the basis of the information presented in the second information presenting step, and hence a group of users of the information can be organized as a small community (such as a family) that is bright and has talks full of topics.  
           [0017]    When the second information presenting step and others are added to the information browse supporting method, the first search condition information may contain one or more pieces of information consisting of a keyword and a confidential flag for indicating whether or not a permission of using this keyword is given to other user, and the second information searching step may involve performing the check about the searched information element by use of only the keyword corresponding to the confidential flag contained in the first search condition information set in the first search condition information setting step with respect to other user.  
           [0018]    According to another aspect of the present invention, an information browse supporting method comprises a first search condition information setting step of making a server set inputted by a user as a search condition corresponding to this user, a second search condition information setting step of making the server set information by a user as a search condition corresponding to a user other than this user, and a step of receiving from the server a result of searching based on the conditions set corresponding to the users in the first and second search condition information setting steps.  
           [0019]    According to a further aspect of the present invention, a program executed by a computer comprises a first search condition information setting process of setting a condition, inputted by any one of a plurality of users, for searching for information suited to this user, as first search condition information on this user, a second search condition information setting process of setting a condition, inputted by any one of the plurality of users in a way that specifies other user, for searching information suited to this other user, as second search condition information on this other user on this other user, an information searching process of searching, from within browsing target information containing a plurality of information elements, for an information element with respect to a certain user in accordance with the first search condition information set in the first search condition information setting process and the second search condition information set in the second search condition information setting process, and an information presenting process of presenting to a certain user a piece of information corresponding to a searched result with respect to a certain user in the information searching process.  
           [0020]    The computer executes this program, whereby the computer can function as a system capable of implementing the information browse supporting method of the present invention, and hence the user-to-user computer-based communications can be vitalized.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0035]    Embodiments of the present invention will hereinafter be described in depth with reference to the accompanying drawings.  
         [0036]    To start with, an outline of an information browse supporting system in one embodiment of the present invention will be explained referring to FIGS. 1 through 3. FIG. 1 is an explanatory diagram showing an outline of architecture of the information browse supporting system in this embodiment as well as showing an available mode thereof. FIGS. 2 and 3 are explanatory diagrams respectively showing a favorite information table and a helpful-care-for-others information table retained by the information browse supporting system  10 .  
         [0037]    The information browse supporting system  10  in one embodiment of the present invention is a system that implements a function as a BS (Broadcasting Satellite) digital tuner (capable of recording), a function as a Web server and a function as a Web mail server. The information browse supporting system  10  is a system installed in a connection mode of being connected to a TV  30  and an Internet  100  and further connected via a LAN (Local Area Network) cable  45  to an unknown number (including “0”) of personal computers (PCs)  40  (incorporating a Web browser). The information browse supporting system  10  is also a system based on the assumption of being used in common by family members (who will hereinafter be called users)as residents of an individual house. Note that the information browse supporting system  10  takes the same external configuration as the BS digital tuner (Set-top Box) generally available on the market.  
         [0038]    The information browse supporting system  10  is defined as a system capable of providing each user with a platform (environment) of being able to administer a user&#39;s own schedule and pieces of information (addresses and so forth) on acquaintances, and transfer and receive the information to and from other users, and providing a platform of being able to easily search for a BS digital broadcasting program suited to a user&#39;s own taste, and search for an E-mail and a Web page important to the user himself or herself among Web pages opened to the public on the Internet  100  and self-addressed E-mails (such as E-mails for advertisements) in a way that enables the user to recognize how much other users show a helpful care for the user himself or herself. Further, the information browse supporting system  10  implements a function of notifying a user taking a helpful care (solicitude) for others (who is hereinafter be called a care-taker) of a BS digital broadcasting program preferable enough to be recommended to a helpful care target (receiving) user (who is hereinafter be called a care recipient) for watching the program.  
         [0039]    Moreover, the information browse supporting system  10  is a system operable (usable) by each user through a remote controller  15  (which is hereinafter abbreviated to the RC  15 ), terminal devices (such as a personal computer, a mobile telephone, a PDA (Personal digital Assistant) and so on) capable of browsing the Web page opened to the public on the Internet  100  and the PC  40 .  
         [0040]    Note that the information browse supporting system  10  is constructed of a control unit  11  including a CPU (Central Processing Unit) and its peripheral circuits (communication circuits for a ROM, a RAM and a LAN, and a communication circuit for the Internet), a HDD (Hard Disk Drive)  12  for storing programs which the control unit  11  (CPU) functions based on, four categories of tables (which will be explained in details later on) and recorded program data, and a BS digital receiving unit  13  as a circuit for receiving the BS digital broadcast. In other words, a hardware architecture of the information browse supporting system  10  is substantially the same as that of the personal computer (main components) capable of receiving the BS digital broadcast, which has already been available on the market. Therefore, a detailed explanation of the hardware architecture of the information browse supporting system  10  is herein omitted. Further, the RC  15  is a device manufactured for the information browse supporting system  10  and having the same hardware architecture and functions as those of a remote controller attached to the existing BS digital tuner, and hence a detailed description of the RC 15  is likewise omitted.  
         [0041]    The HDD  12  of the information browse supporting system  10 , of which the actual operation (use) is started, is stored with a piece of password management table  21 , n-pieces (n is normally an integer of 2 or larger, which will be mentioned in depth later on) favorite information tables  22 , n-pieces of care-for-others information tables  23 , and n-pieces of individual information management tables  24 . Note that among these tables the table existing within the HDD  12  before the start of the actual operation is only the password management table  21  (that is, however, stored with nothing).  
         [0042]    The password management table  21  is a table for storing a user name defined as information used for identifying the user and indicating who is the care-taker, and a User ID and a password defined as pieces of information for authenticating a user identity for every user.  
         [0043]    When starting the operation of the information browse supporting system  10 , normally a specified user sets the user IDs and so forth of the users in the password management table  21 . This setting is, though its detailed description is omitted, done by use of the RC  15  or the PC  40 . Then, if information on a certain user is set in the password management table  21  when performing this setting, a favorite information table  22 , a care-for-others information table  23  and an individual information management table  24  (none of these tables is stored with anything substantial) with respect to the user concerned (precisely each table corresponding to the user ID of this user), are generated on the HDD  12 .  
         [0044]    The favorite information table  22  is, as schematically illustrated in FIG. 2, a table for storing some keywords together with confidential flags, respectively. A keyword stored in the favorite information table  22  with respect to a certain user may be defined as information used for searching for a broadcasting program suited to the taste of the user, and for a Web page and an E-mail important to the user concerned. The confidential flag may be defined as information for indicating ON/OFF states as to whether the user (reference) by other user with the corresponding keyword is inhibited or not. Further, the favorite information table  22  with respect to a certain user is structured to the user to change the contents (set the keyword etc.).  
         [0045]    The care-for-others information table  23  is, as schematically shown in FIG. 3, a table capable of storing a plurality of records (which are generically termed care-for-others information) each consisting of some keywords and a name of setting user. The keyword stored in the care-for-others information table  23  with respect to a certain user, is also used for searching for the suited-to-the-user information (the broadcasting program suited to the taste of the user and the E-mail important to the user). The care-for-others information table  23  with respect to a certain user is, however, structured to store the care-for-others information containing some keywords and the user name as a name of setting user who operates, as a user other than the user related to this table  23 , the information browse supporting system.  
         [0046]    The individual information management table  24  with respect to a certain user is stored with a schedule of this user, addresses of acquaintances of the same user, notifications from other users and an E-mail account of this user. Moreover, the individual information management table  24  with respect to a certain user is further stored with recommended program information for every care-recipient, which is defined as information on broadcasting programs preferable enough to be recommended to the care-recipient for watching the program.  
         [0047]    Based on the premise of what has been discussed so far, the functions of the information browse supporting system  10  will be specifically explained.  
         [0048]    Note that the information browse supporting system  10  involves the use of the Web page in the case of the operations through the Internet  100  and using the PC  40 . Then, as known well, the mobile telephone has a limit in terms of a size of the Web page that can be browsed by the user, and therefore the information browse supporting system  10  has an architecture capable of providing the Web pages for the mobile telephone and the Web pages for the typical computer. Further, when the information browse supporting system  10  is operated by the RC 15 , a screen for operation is displayed on the TV  30 . This screen is essentially the same as the Web page displayed on a display of the computer when operating the information browse supporting system  10  by the typical computer, and is suited to the operation with the RC  15 .  
         [0049]    In short, the information browse supporting system  10 , though operable (usable) by the user through the RC 15 , the terminal devices capable of browsing the Web pages and the PC 40 , has an architecture of implementing the functions corresponding to the categories of the devices used for the above operation. The basic operating procedures thereof are, however, the same whatever category of the device used for the operation may be. Therefore, the following discussion on the functions of the information browse supporting system  10  will be focused on a case where the device (which is hereinafter referred to as an operation terminal) used for operating the information browse supporting system  10  has no particular limit with respect to the Web pages that can be browsed.  
         [0050]    When using the information browse supporting system  10  by the operation terminal, the user inputs a predetermined URL (Uniform Resource Locator), whereby the operation terminal functions to transmit, to the LAN cable  45  or the Internet  100 , a HTTP (HyperText Transfer Protocol) request (which is hereinafter be called a log-in page request) that is to be received and processed by the information browse supporting system  10  (the control unit  11 ).  
         [0051]    On the other hand, the control unit  11  of the information browse supporting system  10  always monitors a receipt of a log-in screen request and, when receiving the log-in page request, executes processes in steps shown in FIG. 4.  
         [0052]    To be specific, when receiving the log-in page request, the control unit  11  executes a log-in information obtaining process (step S 101 ). When in this log-in information obtaining process, the control unit  11  at first transmits the log-in page data to a sender of the log-in page request. Herein, the log-in page data is defined as information for displaying a Web page (which is hereinafter called a log-in page) containing a user ID input box, a password input box, a “transmit” button and others on the operation terminal (which is hereinafter termed a processing target operation terminal) as the sender of the log-in request. Then, the control unit  11 , when obtaining the user ID and the password inputted o the processing target operation terminal (the operation terminal with the log-in page displayed receives the information transmitted when the “transmit” button is pressed, finishes step S 101  (the log-in information obtaining process).  
         [0053]    Note that when using the information browse supporting system  10  through the mobile telephone capable of browsing the Web pages, the user inputs a URL different from the URL described above to the mobile telephone, whereby a mobile telephone oriented log-in page request is transmitted to on the Internet  100 . The information browse supporting system  10  receiving this mobile telephone oriented log-in page request starts the mobile telephone oriented log-in page request corresponding to the process in FIG. 4. In step corresponding to step S 101 , the information browse supporting system  10  executes a process for displaying a Web page suited to a mobile telephone on the mobile telephone having an access thereto. Further, when using information browse supporting system  10  through the RC  15 , the user performs the operation in predetermined steps starting with clicking a menu button provided on RC 15 . The information browse supporting system  10  recognizing that the operation described above has been done, starts executing a process for the RC 15 , which corresponds to the process in FIG. 4. The information browse supporting system  10  executes a process for displaying on the TV  30  a screen capable of inputting the user ID and the password (the screen containing a software keyboard for inputting respective items of information). A relationship between steps which are explained later on and the corresponding steps in the process for the mobile telephone or the RC  15 , are the same, and therefore the following discussion does not include an explanation of the process for the mobile telephone or the RC  15 .  
         [0054]    The control unit  11  having completed the log-in information obtaining process judges whether a couple of the user ID and the password obtained is stored in the password management table  21  (step S 102 ). If this couple of information is not stored in the password management table  21  (step S 102 ; NO), the control unit  11  transmits to the processing target operation terminal a piece of information for displaying an error page defined as a Web page for notifying the accessing user (the operator of the operation terminal) of the non-storage (step S 107 ), and comes to an end of the process shown therein. Whereas if the couple of the user ID and the password obtained is stored in the password management table  21  (step S 102 ; YES), the control unit  11  executes an indication obtaining process for receiving an indication of the process of which an execution should be started from the user who inputted the user ID etc. (who is hereinafter referred to as a log-in user) (step S 103 ). When in this indication obtaining process, the control unit  11 , to start with, transmits main menu page to the processing target operation terminal, thereby displaying on the processing target operation terminal a main menu page on which the operator (i.e., the log-in user) is able to select a process executed by the information browse supporting system  10 . Then, the control unit  11 , when detecting such an event that an operation of indicating an execution of a certain process is done on the processing target operation terminal (when receiving information showing a result of selection by the log-in user, which has been transmitted by the operation terminal on which the main menu page is displayed), finishes step S 103  (an indication obtaining process), and executes in step S 104  the process of which the execution is indicated by the log-in user. In advance of a detailed discussion on the processes that may be executed in step S 104 , the function of the information browse supporting system  10  after completing step S 104  will be explained.  
         [0055]    After the completion of step S 104 , in subsequent step S 105 , the control unit  11  transmits inquiry page data, thereby displaying, on a communication target operation terminal, an inquiry page for inquiring of the log-in user whether the use of the information browse supporting system  10  continues or not. Thereafter, the control unit  11 , when the information showing the result of selection by the log-in user is transmitted from the operation terminal on which the inquiry page is displayed, finishes step S 105 . Then, the control unit  11 , if the indication by the log-in user is to continue the use (step S 106 ; continued), makes a loopback to step S 103 , and executes again the indication obtaining process. By contrast, if the indication by the log-in user is to end the use (step S 106 ; end), the control unit  11  finishes the processes starting with receiving the log-in page request in FIG. 4.  
         [0056]    The respective processes that may be executed in step S 104  will hereinafter be explained in depth.  
         [0057]    According to the present information browse supporting system  10 , the processes (that may be executed in Step S 104 ) of which executions can be indicated on the main menu page, are a favorite information setting process, three categories of care-for-others information setting processes (in a character input mode, a voice input mode and a questionnaire mode), an individual information input browsing process, a program guide browsing process, an E-mail browsing process and a Web page search browsing process.  
         [0058]    The favorite information setting process is a process of which the execution should be indicated by the user when setting and changing the keyword used for searching the broadcasting program suited to the taste of the user and the E-mail important to the user (when setting and changing the keyword in the favorite information table  22 ).  
         [0059]    When in the favorite information setting process, the control unit  11  transmits, to the processing target operation terminal, a piece of information for displaying a Web page (which will hereinafter be called a favorite information setting page) containing a plurality of text boxes for inputting respective keywords, a plurality of check boxes for specifying the confidential flags with respect to the keywords, and a “completion-of-setting” button and others. Note that the control unit  11 , if some keywords and confidential flags have already been set in the favorite information table  22  related to the log-in user, transmits information for displaying the favorite information setting page on which those keywords and flags are displayed.  
         [0060]    Then, the control unit  11 , when receiving information showing some set-by-user keywords and corresponding confidential flags which information is to be transmitted when the processing target operation terminal with the favorite information setting page displayed detects the click on the “completion-of-setting” button, rewrites the contents of the related-to-the-login-user favorite information table  22  into those corresponding to the above information, and finishes the step S 104  (the favorite information setting process).  
         [0061]    Further, among the three categories of care-for-others information setting processes of which the executions can be indicated from on the main menu page, each of the care-for-others information setting processes in the character input mode and in the voice input mode is a process of which the execution should be indicated by a user having a concern about other user.  
         [0062]    [0062]FIG. 5 shows an operating procedure of the control unit  11  when in the care-for-others information setting process in the character input mode. As shown in FIG. 5, when in the care-for-others information setting process in the character input mode, the control unit  11  at first executes a care-for-others comment obtaining process (step S 201 ). When in this care-for-others comment obtaining process, the control unit  11  transmits care-for-others comment input page data to the processing target operation terminal, thereby displaying on the processing target operation terminal a Web page (which is hereinafter be referred to as a care-for-others comment input page) containing a setting usr name display box  71 , a care-recipient name selection box  72 , a care-for-others comment input box  73 , a “register” button  74  and so on. Note that the control unit  11  has the care-for-others comment input page displayed, which contains the setting user name display box  71  where a name of the log-in user (“mother” in FIG. 6) is displayed as the care-for-others comment input page data, and the care-recipient name selection box  72  (which is a so-called drop-down list box: “Kenichi” is selected in FIG. 6) in which any one of the user names excluding the name of the log-in user himself or herself that are stored in the password management table  21 .  
         [0063]    The log-in user indicating the execution of the care-for-others information setting process in the character input mode, manipulates the care-recipient name selection box  72  on the care-for-others comment input page described above, thus displaying a name of the user about which log-in user has a concern in the care-recipient name selection box  72 . Then, the log-in user inputs what he or she has the concern about in the natural language (normal sentences) to the care-for-others comment input box  73 . Subsequently, the log-in user clicks a “register” button  74 .  
         [0064]    With such a series of operations, the operation terminal on which the care-for-others comment input page transmits, onto the network (the LAN cable  45  or the Internet  100 ), the information containing the care-for-others comment defined as character information inputted to the care-for-others comment input box  73  and the name of the care-recipient as the user name displayed in the care-recipient name selection box  72 , which information is to be received by the information browse supporting system  10 .  
         [0065]    The control unit  11  receiving the information containing the care-for-others comment and the care-recipient name finishes the care-for-others comment obtaining process (step S 201  in FIG. 5). In subsequent step S 202 , the control unit executes a process for analyzing (interpreting) a content of the care-for-others comment (which is a kind of auto summarizing process), thereby determining some keywords (e.g., “stress” and “health”) with which the information that should be browsed by a user who might be in such a psychological and physical condition as to be assumed from the content of that care-for-others comment. Note that the determination of the keyword involves the use of methods such as computing a word-to-word correlation and join degree by, for example, text mining, associative analysis etc. which are generally performed based on the natural language inputted as the comments, and determining as a keyword the word obtained as a result of this computing.  
         [0066]    Then, the control unit  11  sets the care-for-others information consisting of some keywords determined and the setting user name (the log-in user name) in the care-for-others information table  23  corresponding to the care-recipient name (step S 203 ), and finishes the care-for-others information setting process. Note that the control unit  11 , if the care-recipient information set by the same user has already existed, executes a process of setting the care-recipient information of this time as a substitute for the existing care-recipient information in the care-for-others information table  23  in this step S 203 .  
         [0067]    Moreover, when in the care-for-others information setting process in the voice input mode, the control unit  11  executes a process having substantially the same content as the care-for-others information setting process in the character input mode except for a point that the care-for-others comment is inputted by a voice. To be specific, when in the care-for-others information setting process in the voice input mode, the control unit  11 , in step corresponding to step S 201 , displays on the processing target operation terminal a Web page provided with an area (box) in which the log-in user is able to specify (select) a name of the care-recipient, and with buttons for completing the selection for the care-recipient and for indicating a start of inputting the voice. Then, the control unit  11 , when the information showing he care-recipient name is transmitted upon clicking the button concerned, shifts to a state of accepting the voice input and stores voice data for a predetermined period of time.  
         [0068]    Thereafter, the information browse supporting system  10 , in step corresponding to step S 202 , converts the stored voice data into character information, and deals with the character information as a care-for-others comment, thus determining some keywords. Then, the control unit  11  in step corresponding to step S 203 , sets some keywords determined and the setting user name in the care-for-others information table  23  corresponding to the care-recipient name acquired, and comes to an end of the care-for-others information setting process in the voice input mode.  
         [0069]    It is to be noted that this care-for-others information setting process in the voice input mode is provided in order for users unsuitable for manipulating the keyboard to easily set the care-for-others information by use of the typical computer (incorporating a microphone) and for the general users to easily set the care-for-others information by the mobile telephone on which the inputting of the character information is time-consuming.  
         [0070]    As described above, the care-for-others information setting processes in the character and voice input modes are processes of which the executions should be indicated by the user (having a desire-to-input care-for-other comments) who has the concern about the other user. By contrast, the care-for-others information setting process in the questionnaire mode is a process of which the execution should be indicated by the user who has no particular desire-to-input care-for-others comment (this sort of comment does not occur to the user).  
         [0071]    A content of the care-for-others information setting process in the questionnaire mode will be explained referring to FIGS. 7 and 8. FIG. 7 is a flowchart showing the care-for-others information setting process in the questionnaire mode. FIG. 8 is an explanatory diagram showing the care-for-others input page displayed on the processing target operation terminal when the care-for-others information setting process in the questionnaire mode is executed.  
         [0072]    As shown in FIG. 7, when in the care-for-others information setting process in the questionnaire mode, the control unit  11 , to begin with, executes a questionnaire process (step S 301 ). In this questionnaire process, the control unit  11  transmits questionnaire page data to the processing target operation terminal, thereby displaying on the processing target operation terminal a Web page (which is hereinafter called a questionnaire page) provided with, as schematically shown in FIG. 8, a setting user name display box  81 , a care-recipient name selection box  82 , an questionnaire area  83 , a “register” button  84  and so forth. The setting user name display box  81  and the care-recipient name selection box  82  provided on this questionnaire page have the same items of entries (functioning the same) as those in setting user name display box  71  and the care-recipient name selection box  72  displayed on the care-for-others comment input page (FIG. 6). Then, the questionnaire area  83  is, as obvious from FIG. 8, an area where a variety of questions are given, and answers (“1”˜“5”) to each of these questions are selectable. Further, the questions put in the questionnaire area  83  are schemed to grasp psychological and physical conditions of the care-recipient from the answers (and therefore keywords enabling the information suited to the care-recipient to be searched, can be also specified).  
         [0073]    The log-in user indicating the execution of the care-for-others information setting process in the questionnaire mode, manipulates the care-recipient name selection box  82  on the questionnaire page described above, thus displaying a name of the target user in the care-recipient name selection box  82  and selecting an answer to each question put in the questionnaire area  83 . Then, the log-in user clicks (presses) the “register” button  84 .  
         [0074]    Upon the click on the “register” button  84 , the processing target operation terminal with the questionnaire page displayed thereon transmits onto the network the information in a predetermined format that is to be received by the information browse supporting system  10 , the information containing the answers to all the questions and the care-recipient name entered in the care-recipient name selection box  82 .  
         [0075]    The control unit  11  receiving this item of information finishes the questionnaire process (step S 301  in FIG. 5). In subsequent step S 302 , the control unit  11  determines some keywords making it possible to search for the information to which the care-recipient should refer, from the answers to the respective questions that are contained in the information described above. Then, the control unit  11  enters the some keywords determined and the setting user name (the log-in user name) in the care-for-others information table  23  corresponding to the care-recipient name (step S 303 ), and finishes the care-for-others information setting process in the questionnaire mode.  
         [0076]    The next discussion will be focused on a program guide browsing process, an E-mail browsing process, a Web page browsing process and an individual information setting browsing process.  
         [0077]    The discussion starts with touching on the program guide browsing process.  
         [0078]    [0078]FIG. 9 shows operating steps of the control unit  11  when in the program guide browsing process. As shown in FIG. 9, in the program guide browsing process, the control unit  11  reads all the keywords set in the favorite information table  22  related to the log-in user, and further reads all pieces of care-for-others information (containing the keywords and the setting user name) set in the care-fore other information table  23  pertaining to the log-in user (step S 401 ). Subsequently, the control unit  11 , based on the readout keywords and service information retained at that point of time, searches for programs (of which program names and captions contain the keywords entered in the favorite information tables  22 ) and programs (of which program names and captions contain the keywords entered in the care-for-others information table  23 ) that should be, other users consider, watched by the log-in user (step S 402 ). Note that the service information indicates a broadcasting time and a title of each of the programs that are always broadcast within a predetermined period by the BS digital broadcast. Further, in this step S 402 , the control unit  11  also executes a process of determining a recommendation degree corresponding to a hit keyword count with respect to each of the searched programs. Specifically, the control units  11  executes the process of adding a value obtained by multiplying the number of hit keywords set in the care-for-others information table  23  by “1.5” to the number of hit keywords set in the favorite information table  22 , and calculating as recommendation degree a value (if over “5”, however, the value is “5”) obtained by rounding off decimals of the added value. In short, the control unit  11  computes (determines) the recommendation degree in such a procedure that if the hit keyword counts are equal, the recommendation degree of the program having a larger number of keywords in the care-for-others information table  23 , which are contained in the hit keywords, takes a larger value.  
         [0079]    Then, the control unit  11  transmits to the processing target operation terminal a piece of information for displaying a program guide page on which pieces of information on the searched programs are sorted in a format corresponding to the recommendation degrees (step S 403 ). To be more specific, in the process in this step S 403 , the program guide page as schematically illustrated in FIG. 10, i.e., the program guide page on which the programs searched in step S 402  are colored (screened by meshing in FIG. 10) corresponding to the recommendation degrees, and the programs searched by the keywords entered in the care-for-others information table  23  have padding of information (“recommended-by-mother programs) implying the keyword setting user), is displayed on the processing target terminal.  
         [0080]    Thereafter, the control unit  11  executes processes corresponding to contents of the operations on the program guide page, such as a process of displaying the program guide page with different dating, a process of displaying detailed information on the specified programs, a process of displaying a process of displaying a program guide page showing only the programs searched in step S 402 , and a process of accepting a recording reservation and a hear-and-watch reservation (step S 404  in FIG. 9). Then, when indicated to finish, the control unit  11  finishes step S 404  and the program guide browsing process.  
         [0081]    Next, the E-mail browsing process will be explained.  
         [0082]    [0082]FIG. 11 shows operating steps of the control unit  11  when in the E-mail browsing process. As shown in FIG. 11, in the E-mail browsing process, the control unit  11  receives E-mails addressed to the log-in user from a mail server subscribed by the log-in user and stores these mails according to the E-mail account entered in the individual information management table  24  of the log-in user (step S 501 ). Subsequently, the control unit  11  reads all the keywords entered in the favorite information table  22  related to the log-in user, and further reads all pieces of care-for-others information (the keywords and the setting user name) set in the care-for-others information table  23  pertaining to the log-in user (step S 502 ). Then, the control unit  11  searches for, based on these keywords, the E-mails (containing the keywords set in the favorite information table  22  or in the care-for-others information table  23 ) conceived high in reading value to the log-in user from all the E-mails received this time (step S 503 ). Further, in step S 503 , the control unit  11  executes the process of computing the recommendation degree of each of the E-mails searched in the same way as done in step S 402  described above.  
         [0083]    Then, the control unit  11  transmits to the processing target operation terminal a piece of information for displaying a receiving tray page in which titles etc. of the E-mails searched are shown in a format corresponding to the recommendation degree (step S 504 ). To be specific, in the process in this step S 504 , the control unit  11  displays on the processing target operation terminal a receiving tray page on which, as schematically shown in FIG. 12, the E-mails searched in step S 503  are colored (screened by meshing in FIG. 12) corresponding to the recommendation degree, and the E-mails searched by the keywords set in the care-for-others information table  23  contain the information indicating the keyword setting user (“mother” in FIG. 12).  
         [0084]    Thereafter, the control unit  11  executes processes corresponding to the contents of the operations on the receiving tray page, such as a process of displaying actually the contents of the E-mails on the processing target operation terminal, and a process of deleting the E-mails (step S 505  in FIG. 11). Then, when indicated to finish, the control unit  11  finishes step S 505  and the E-mail browsing process.  
         [0085]    Further, when in the Web page search browsing process, the control unit  11  searches for Web pages each containing the keywords in the favorite information table  22  related to the log-in user and in the care-for-others information table  23  from the Web pages within some Web sites previously registered y the log-in user, and determines the recommendation degrees of the respective Web pages in the steps already explained. Then, the control unit  11  displays on the processing target operation terminal a result-of-search page on which some items (which are hereinafter termed titles) of the contents of the searched Web pages are sorted in sequence of the recommendation degrees, the respective titles are displayed in a form corresponding to the recommendation degrees, and the setting user names are also displayed with respect to the titles of the Web pages searched by the keywords in the care-for-others information table  23 . Then, the control unit  11  executes processes corresponding to the contents of the operations on the result-of-search page, such as a process of displaying actually all the contents of the searched Web pages on the processing target operation terminal. Then, when indicated to finish, the control unit  11  finishes the Web page search browsing process.  
         [0086]    Next, the individual information setting browsing process will be described. Note that the individual information setting browsing process is a process of setting and browsing the contents of the individual information management table. This individual information setting browsing process involves executing processes of setting an browsing the schedules, addresses and notifications, however, contents of these processes are the same as the processes implemented by the computer into which a typical scheduler is installed, and hence the explanation thereof is omitted.  
         [0087]    When in the individual information setting browsing process, the control unit  11  transmits a piece of information for displaying a menu page for setting the individual information to the processing target operation terminal. On this menu page, there can be executed a variety of processes of setting the schedule and address and doing the browse, and a recommended program information displaying process of displaying recommended program information. When indicated to execute the recommended program information displaying process, the control unit  11  functions in steps shown in FIG. 13.  
         [0088]    To be specific, the control unit  11 , to begin with, specifies a first care-for-others information table  23  (which is the oldest in creation time) not related to the log-in user as a processing target care-for-others information table  23 , and further specifies a care-recipient (identified by the user ID stored as one element of a mapping in the process target care-for-others information table  23 ) (step S 601 ). Then, the control unit  11  judges whether or not the care-for-others information entered by the log-in user is set in the processing target care-for-others information table  23  (step S 602 ). If the care-for-others information entered by the log-in user is not set in the processing target care-for-others information table  23  (step S 602 ; NO), the control unit  11  judges whether or not there are left unprocessed processing target care-for-others information tables  23  related to users other than the log-in user (step S 607 ). If the unprocessed processing target care-for-others information tables  23  are left (step S 607 ; YES), the control unit  11  loops back to step S 601  and re-executes the processing with respect to the next care-for-others information table  23 .  
         [0089]    On the other hand, if the care-for-others information entered by the log-in user is set in the processing target care-for-others information table  23  (step S 602 ; YES), the control unit  11 , based on the keywords contained in the care-for-others information and the service information, searches for programs suited to the care-recipient (step S 603 ).  
         [0090]    If the search for the program is hit (step S 604 ; YES), the control unit  11  reads all the keywords with the confidential flags set OFF within the favorite information table  22  relative to the care-recipient specified instep S 601  (step S 605 ). Then, the control unit  11 , based on the readout keywords and the keywords used for searching, determines a recommendation degree of each of the programs searched. Subsequently, the control unit  11  stores the individual information management table  24  with pieces of information containing the determined recommendation degrees, the information on the searched programs and the hit keywords as an item of recommended program information on the care-recipient specified in step S 601  (step S 606 ).  
         [0091]    Next, the control unit  11  judges whether or not there are left the unprocessed care-for-others information tables  23  related to the users other than the log-in user (step S 607 ). If there are left the unprocessed care-for-others tables  23  (step S 607 ; YES), the control unit executes again the processes from step S 601  with respect to the next care-for-others information table  23 .  
         [0092]    Then, the control unit  11 , when completing the processes for the care-for-others information tables  23  with respect to all the users excluding the log-in user (step s 607 ; NO), transmits to the processing target operation terminal the information created based on all pieces of recommended program information stored in the individual information management table  24 , thereby displaying on the processing target operation terminal a recommended program page defined as a Web page on which pieces of information on the programs recommended to the care-recipient are displayed in sequence of the recommendation degrees together with the hit keywords in the favorite information table  22  for every care-recipient (step S 608 ). In other words, in the process in step S 608 , there is displayed, on the processing target terminal, the recommended program page on which the log-in user is able to recognize, for every recipient, the programs (searched by the keywords contained in the care-for-other information) that should be recommended to the care-recipient, and it is feasible to comprehend which part of the program is preferable to the care-recipient (wherein the keyword is comprehensible) with respect to the program (containing the keyword with the confidential flag set OFF in the favorite information table  22  of the care-recipient) among those recommended programs, to which the care-recipient shows his or her taste.  
         [0093]    Thereafter, the control unit  11  executes processes corresponding to the contents of the operations on the recommended program page of the log-in user, such as a process of storing the individual information management table  24  of other user with the information as a piece of notification inputted with the same other user specified (step S 609 ). Then, when indicated to finish, the control unit  11  finishes step S 609  and the recommended program information displaying process.  
         [0094]    As discussed above in depth, according to the information browse supporting system  10 , each user is able to easily search for the BS digital broadcasting program suited to the user&#39;s own taste, and search for the E-mail and the Web page important to the user himself or herself among Web pages opened to the public on the Internet  100  and self-addressed E-mails (such as E-mails for advertisements) in a way that enables the user to recognize how much other users show the helpful care for the user himself or herself. Further, the information browse supporting system  10  is capable of notifying the caretaker of the program preferable enough to be recommended to the care-recipient for watching the program together with the information (the keyword) showing which part of the program is preferable to the care-recipient. Moreover, each user can set confidential the keyword that the user desires to conceal from others, and therefore no problem of privacy arises.  
         [0095]    Accordingly, the user browses the information presented to the user himself or herself through the present information browse supporting system  10 , and is thereby able to recognize how other user has a concern about the user himself or herself and in turn show a kind care to other user. As a result, the group consisting of the users of the information browse supporting system  10  becomes a group of members (e.g., family members) who are bright and have talks full of topics.  
         [0096]    &lt;Modified Example&gt; 
         [0097]    The information browse supporting system  10  according to the embodiment discussed above can be modified in a variety of forms. For instance, the information browse supporting system  10  in the embodiment is the system implementing the function as the BS digital tuner and may also be configured as a system (a so-called home server) used in connection with the BS digital tuner.  
         [0098]    Further, the information browse supporting system  10  may be configured in a way that does not include the BS digital tuner at all, and may also be configured to have only a function of receiving the service information and displaying the program guide based on the service information with respect to the BS digital broadcasting program.  
         [0099]    Further, the information browse supporting system  10  is configured based on the assumption of being used in the individual house bur may be modified to execute the processes for each of a plurality of groups, and, if the unnecessary functions (such as the program recording function etc.) are removed, it follows that a server capable of providing the services described above to the members of the plurality of groups.  
         [0100]    Still further, the receiving tray page provided by the information browse supporting system  10  is structured the same as what is provided by a typical Web mail server (what is structured to neither execute the process of changing the display mode corresponding to the recommendation degree nor indicate the recommending user), the E-mail important to the user (that should be read by the user) can be easily found out by changing an E-mail importance (represented by a value of X-Priority etc. of a mail header) according to the recommendation degree.
