CROSS-REFERENCE TO RELATED PATENT APPLICATION 
       [0001]    This application claims the benefit of Korean Patent Application No. 10-2006-0125662, filed on Dec. 11, 2006, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference. 
       BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to an apparatus and a method of providing a service, and more particularly, to an apparatus and a method of providing a personalized service, in which a user generates and uses the personalized service in a web based environment. 
         [0004]    This work was supported by the IT R&amp;D program of MIC/IITA.[2005-S056-02, Development of Open API and Service Platform Technologies] 
         [0005]    2. Description of the Related Art 
         [0006]    There is no antecedent related to a technique of providing a personalized service in an open environment based on Parlay architecture. However, there exist some antecedents related to the technique of providing the personalized service in the Internet or existing neural network. 
         [0007]    There is Korean Patent No. 0543311 as an antecedent. In the antecedent, an audio file corresponding to greetings and a destination name among the destination menu information is generated and stored, after destination menu information in a text type is received from a subscriber on a web. When a service for the subscriber is requested to be provided, the previously stored greetings are transmitted, and destination announcements including destination names are transmitted so that a user can call the subscriber. 
         [0008]    There is Korean Patent No. 0420486 as another antecedent. In the antecedent, a user estimates member information that is input when the user is registered as a member, a user class according to rules defined by an administrator, and a pattern of information used by the user so as to provide the most suitable information for the user. 
         [0009]    There is Korean Patent No. 2005-0071720 as another antecedent. In the antecedent, a customized homepage is produced on the basis of a preference by receiving the preference in a layout and a style of a homepage from the user. 
         [0010]    There is Korean patent application publication No. 2004-0001346 as another antecedent. In the antecedent, an application customized for a user is provided during runtime of a service by allowing the user to select desired components among components that constitute an application when the user subscribes to the service. That is, a customized service is provided by assembling components during runtime of the service by using a service definition in which correlation between components selected by the user and an application template is defined. In the present antecedent, although it is intended to customize not data used by the application but application logic, personalization is provided by using a method in which service construction information is stored in a database and used during runtime of the service. 
         [0011]    There is U.S. Pat. No. 7,100,107B2 as another antecedent. The present antecedent patent relates to a method in which user information and preferences are gathered by using hypermedia and applied to service components that constitute a service. Like the aforementioned patent (Korean patent application publication No. 2004-0001346), in the present patent, personalization is provided by maintaining a service application provided by a service provider and applying input data of the user to the service. 
         [0012]    In the conventional techniques, personal information (for example, personal profile information, personal tastes, terminal capability, and the like) is gathered from a user, stored by using on-line or off-line means, and suitably used when the service is executed in order to provide a personalized service depending on the user. That is, the service provider prepares a service logic program, and the user inputs personal information through a service provisioning process. The data is used when the service logic is executed, and the personalized service is provided. 
         [0013]    The existing techniques are suitable for a structure of a current communication network. That is, in the structure, a service provider who owns a communication network provides a service, and a general user uses the service. In order to provide a personalized service depending on the user in the existing communication environment, the service provider gathers personal information from users through a means such as a web and uses the gathered information during runtime of the service logic program. 
         [0014]    However, in the existing techniques, limited personalization can be obtained. The service provider gathers information needed for the service in order to provide the service and uses the gathered information according to predetermined service logic. Finally, the users provides personalized information according to predetermined a scenario within a range defined by the service provider and receives a personalized service. In addition, although it is possible for the personalized service to use personal data (a phone book, a schedule, a multimedia file, and the like) stored in a personal device, the existing techniques do not provide a method of using the personal data. 
         [0015]    Current service users gradually changes from passive users to active users and requires the existing service to be slightly modified or requires completely new service to be provided. The existing method of providing personalization in the current communication environment cannot satisfy various desires of the users. 
         [0016]    In addition, in the existing communication network environment, since the service logic is constructed with a complex communication network protocol, it is possible for only experts in programming and communication networks to prepare the service logic. Since it takes long time and hard efforts to create a new service and start the service, it is difficult to successively create new services suitable for various desires of users. 
       SUMMARY OF THE INVENTION 
       [0017]    The present invention provides a method and an apparatus in which a user accesses a service portal by using a web browser of a personal device, generates a personal service using Parlay Open API, and use the generated service. 
         [0018]    According to an aspect of the present invention, there is provided an apparatus for providing a web based personalized service, the apparatus including: a service information storage unit in which information on a service including a service name and a URL for dynamically providing personal data is stored; a service generation unit which provides software used to generate a service so that a user generates the service by using the software suitable for an operating system of a personal device of the user; a service registration unit which stores the generated service, receives the information on the generated service from the user, and stores the information in the service information storage unit; and a service execution unit which provides the information on services generated by the user to the user and executes a service which is requested by the user to be executed on the basis of the information on the generated services. 
         [0019]    According to another aspect of the present invention, there is provided a method of providing a web based personalized service, the method including: (a) providing software used to generate a service so that a user generates the service by using the software suitable for an operating system of a personal device of the user; (b) storing the generated service, receiving information on the generated service including a service name and a URL for dynamically providing personal data, and storing the information; and (c) providing the information on services generated by the user to the user and executing a service which is requested by the user to be executed on the basis of the information on the services.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0028]    Now, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. 
         [0029]      FIG. 1  is a conceptual view illustrating an apparatus for providing a personalized service according to an embodiment of the present invent. 
         [0030]    Referring to  FIG. 1 , a system for providing a personalized service according to the embodiment of the present invention is constructed with a personal device  100  and a service portal  120 . The service portal  120  is connected to the personal device  100  through the Internet. The personal device interacts with a user by accessing the service portal  120  through a web browser  110 , which is installed in a mobile phone  101 , a personal digital assistant (PDA)  102 , a tablet PC  103 , a notebook computer  104 , a desktop PC  105 , and the like and displaying a web page provided by the service portal  120  on a screen. The service portal  120  provides functions of a web server for generating and providing a service and a service application server which executes the generated service. 
         [0031]      FIG. 2  is a schematic diagram illustrating an apparatus for providing a personalized service according to an embodiment of the present invention. 
         [0032]    Referring to  FIG. 2 , the service portal  120  includes a web server  200 , a service survey function unit  210 , a service customizing function unit  220 , a service generation function unit  230 , a service execution and management function unit  240 , a personal data management function unit  250 , and a service application server  260 . 
         [0033]    Both of the service customizing function unit  220  and the service generation function unit  230  provide a function of generating a personalized service. The service customizing function unit  220  serves to generate a personalized service so as to customize a predetermined part of a template for a user by providing a predetermined service template to the user. The service generation function unit  230  serves to generate a completely new service for a user. 
         [0034]    The web server  200  allows the service portal  120  to be accessed through a web browser of a personal device  100  and serves to transmit a web page requested by the user. 
         [0035]    The service survey function unit  210  is constructed with a service searching unit  211  and a service experience unit  212 . The service searching unit  211  serves to search for a desired service by allowing the user to input a keyword. The service experience unit  212  receives an experience animation for a service found by the user from an experience animation storage unit  271  and transmits the experience animation to the web browser of the user. The user controls the animation by using play, stop, and pause functions in a menu. 
         [0036]    The service customizing function unit  220  is constructed with a service customizing providing unit  221 , a service simulation unit  222 , and a service registration unit  223 . The service customizing providing unit  221  receives a template for a service requested by the user from a service template storage unit  272  and displays the template on the web browser of the user. When customizing for the user is completed, information customized by the user is transmitted to the service simulation unit  222  and the service registration unit  223 . 
         [0037]    The service simulation unit  222  receives a simulation animation corresponding to the service requested by the user from a service simulation animation storage unit  273 , applies the service customizing information transmitted by the service customizing providing unit  221  to the animation, and transmits the animation to the web browser of the user. The user controls the animation by using play, stop and pause functions in a menu. 
         [0038]    The service registration unit  223  receives information on service registration from the user. When a service name, a URL for dynamically providing personal data, a log file recording permission, a service reservation permission, a timer permission, and a service loop permission are input by the user, an input value of the user and the service customizing information provided by the service customizing providing unit  221  are applied to a service logic program of  FIG. 3 . Then, the service logic program is built and made into an execution file. Information on the service is stored in the service information storage unit  275 , after the service logic program is built. 
         [0039]    The service information storage unit  275  stores information on services generated by the user. As shown in  FIG. 6 , the service information stored in the service information storage unit  275  includes a service name, a service web page URL, a location of a service execution file, a URL for dynamically providing personal data, a log permission, and a service status. 
         [0040]    The service generation function unit  230  is constructed with a service generation unit  231 , a service upload unit  232 , and a service registration unit  233 . The service generation unit  231  serves to download software for service generation and testing tools suitable for an operating system of the personal device selected by the user to the personal device of the user. The user installs the downloaded software in the personal device after downloading the software and generates the service by using the software. In a method of generating the service, a graphic editor is used. The graphic editor is constructed with a building block palette and a canvas. A building block is a basic unit which constitutes the service and corresponds to Parlay X Open API, condition statements of a program (“if”, “goto”, “start”, “end”, and the like), or utility API (API for user I/O, file handling, timer handling, and the like). The user connects building blocks drawn on the canvas to one another by selecting a desired building block in the building block palette and dragging the selected building block. When graphical editing is completed, the editing result is stored. Code is generated as the service logic program. The generated code is a web application. After the codes are generated, the service is built in order to create an execution file. 
         [0041]    The user requests the service upload unit  232  to upload the service and uploads the service generated in the personal device  100  to the service portal  120 . After the service is uploaded, the service registration unit  233  allows the user to input a service name, a URL for dynamically providing personal data, and a log file recording permission. When the user completed the input operation, the information on the service is stored in the service information storage unit  275  by using the input value of the user. 
         [0042]    The service execution and management unit  240  is constructed with a service execution unit  241 , a service information management unit  242 , and a service deleting unit  243 . The service execution unit  241  displays a service list stored in the service information storage unit  275  on the web browser of the user. When a service is selected from the service list, the service execution unit  241  receives the service web page URL of the service from the service information storage unit  275  and transmits the web page to the web browser of the user. When the user clicks a start button in the service web page, the service execution unit  241  receives a location of a service execution file from the service information storage unit  275  and requests the service application server  260  to drive the service execution file. Then, a value of a status field of the service is modified into active in the service information storage unit  275 . When the user later selects a stop button of the service, the service execution unit  241  requests the service application server  260  to stop the service. Then, a value of the status field of the service is modified into idle in the service information storage unit  275 . 
         [0043]    When the user modifies the service information, after the service information management unit  242  receives the service information from the service information storage unit  275  and transmits the service information to the web browser of the user, the value modified by the user is stored in the service information storage unit  275 . 
         [0044]    The service deleting unit  243  deletes the information on the service in the service information storage unit  275 , when the user requests a service to be deleted. 
         [0045]    The personal data management function unit  250  is constructed with a member management unit  251 , a personal data management unit  252 , a personal data download unit  253 , and a personal data upload unit  254 . A member management unit  251  stores membership subscription and member information in the personal data storage unit  276 . The personal data to be managed by the personal data management unit  250  includes a phone book, a group phone book, a multimedia file, a schedule, call records, and the like. The personal data management unit  252  serves to add/modify/delete the personal data. The personal data download unit  253  serves to download the personal data stored in the personal data storage unit  276  of the service portal  120  to the personal device  100 . The personal data upload unit  254  serves to upload the personal data stored in the personal device  100  to the personal data storage unit  276  of the service portal  120 . 
         [0046]    The service application server  260  drives or stops a service process by a request of the service execution unit  241 . Then, the driven service process is periodically service-live-tested. When the service process is finished, a value of the status field of the service is modified into idle in the service information storage unit  275 . 
         [0047]    A web browser  280  of the personal device  100  interacts with the user by accessing the service portal  120  and displaying a web page provided by the service portal  120  on the personal device. When the personalized service of the service portal  120  requests the personal data stored in the personal device  100  to be provided during runtime, a function unit  290  of dynamically providing personal data serves to transmit requested data. The function  290  of dynamically providing personal has to be provided to the personal device as a web service or server program for communication. 
         [0048]      FIG. 3  is a schematic diagram illustrating a service template for providing service customizing according to an embodiment of the present invention. 
         [0049]    Referring to  FIG. 3 , a service template is constructed with service template construction information  300  and a service application  310 . The service is constructed with components. The components correspond to Parlay X Open API, condition statements of a program (“if”, “goto”, “start”, “end”, and the like), or utility API (API for user I/O, file handling, timer handling, and the like). 
         [0050]    The service template construction information  300  includes graphical information for graphical shape as shown  FIG. 4 . It is on types of the components which constitute the service template and component connection information. The service template construction information  300  is transmitted to the web browser of the user and displayed so that the user can perform a customizing process. The service application  310  is constructed with a service web page  311  and a service logic program  312  as service code for the service template. The service web page  311  receives a user&#39;s input needed for executing a service logic program  312  from the user, before executing the service logic program  312 . The service web page  311  provides a GUI so that the user can start the service or stop the executed service. The service logic program  312  includes logic of the service. 
         [0051]      FIG. 4  illustrates a shape of a service template displayed to user in order to provide a service customizing process according to an embodiment of the present invention. 
         [0052]    Referring to  FIG. 4 , parts  400  and  410  which a user can customize among combinations of components are alerted to the user. The user can customize the parts by modifying properties of the components  400  or selecting  410  one component among a plurality of candidate components. When the properties of the components are modified, there is provided a function of searching for member information (a phone number, a weblog/homepage URL, taste in contents) or personal data (a phone book, a group phone book, and a multimedia file) stored in a portal. 
         [0053]      FIG. 5  illustrates a format of a result value of a service customizing process according to an embodiment of the present invention. 
         [0054]    Referring to  FIG. 5 , the format of the result value is represented as a list of “(component name, {property  1 , value}, . . . , {property n, value})”. The property of the component that is not customized by the user is set as “Default”. 
         [0055]      FIG. 6  illustrates a format of service information stored in a service information storage unit  275  as a result of registration of service according to an embodiment of the present invention. 
         [0056]    Referring to  FIG. 6 , service information stored in the service information storage unit  275  includes a service name, a service web page URL, a location of a service execution file, a URL for dynamically providing personal data, a log permission, and a service status. The service information storage unit  275  includes information on the services generated by the user. 
         [0057]      FIGS. 7 and 8A  to  8 M are flowcharts illustrating a method of providing web-based personalized service according to an embodiment of the present invention.

         [0063]    When the user inputs a service customizing instruction (operation S 750 ), the service portal receives a service template list from the service template storage unit  272  (operation S 751 ). After a web page for the received service template list is transmitted to the user (operation S 752 ), when the user selects a service from the list (operation S 753 ), the service portal receives the service template construction information  300  and the service application  310  for the service selected by the user from the service template storage unit  272  (operation S 754 ) and transmits the service template construction information  300  to the user (operation S 755 ). The user completes the customizing process for parts which can be customized in the service template construction information page (operations S 756  and S 757 ). When the customizing process is completed, the service portal receives an animation corresponding to the service from the simulation animation storage unit  273  (operation S 758 ), applies the customizing information to the animation (operation S 759 ), and transmits the animation to the user (operation S 760 ). When the user completes a viewing process of the animation after controlling the animation (operations S 761  and S 762 ), the service portal transmits a web page for registering a service to the user (operation S 763 ). The user completes an input process of the user in a service registration form (operation S 764 ), the service portal applies the input value of the user for the service registration and the service customizing information to the service logic program  312  (operation S 765 ). The service program  312  is built (operation S 766 ). The input value of the user for the service registration and the information on the service execution file is stored in the service information storage unit  275  (operation S 767 ). When the service registration is completed, a message box which informs the user that the registration is completed is transmitted to the user (operation S 768 ). The service portal transmits mypage to the user (operation S 714 ) and waits for a user input (operation S 702 ). 
         [0064]    When the user inputs a service generation instruction (operation S 770 ), the service portal receives a software list for each operation system from the service generation tool storage unit  274  and transmits a web page about the list (operation S 771 ). When the user selects a software download from the list (operation S 772 ), the service portal receives the software selected by the user from the service generation tool storage unit  274  and downloads the software to the user. When the download is completed, a message box which informs the user that the download is completed is transmitted to the user (operation S 773 ). The user executes the downloaded software and installs the software in the personal device (operation S 774 ). The user completes the installation of the software and performs visual editing of the service by using a graphic editor which is the service generation tool (operation S 775 ). After the editing of the service is completed, the service is stored (operation S 776 ). Both service code and makefile are automatically created by inputting a visual form of the service by using a code generation tool (operation S 777 ). The automatically generated service code is built by using the created makefile (operation S 778 ). The built service is tested by using a service testing tool (operation S 779 ).
