An Internet Information Search System via Component Based Software Development}

The present invention relates to a component-based Internet search system based on the concept of Component Based Software Development (CBSD), and more particularly, a design method that can be applied to the design and manufacture of various search systems such as various product search systems in an e-commerce system. It is about.

Given the increasingly difficult and complicated nature of software, the need for software development based on components is on the rise. Here, a component can create a complete software system by assembling parts of a piece of software as if assembling electronic parts to produce an electronic product. A software component having an independent unit function is called a component. As illustrated in FIG. 1, an electronic board component and a software component that processes unit tasks such as a workflow component, a user interface component, a data management component, and an electronic mail component are combined to form a groupware package.

As the complexity and cost of software development increases exponentially, component-based software development techniques enable the cheapest and fastest software development through software reuse. Research is underway on frameworks, reusable components that model and partially implement data and functions that are common and commonly used by a variety of applications in specific domains. In addition, as the development of object-oriented software using UML (Unified Modeling Language) is generalized in consideration of the complexity of software, the importance of requirement analysis and design information using UML is emphasized. If software is developed based on the framework, reusability and maintainability will be greatly improved. To this end, the framework must be identified from the system requirements analysis information, and the information required to implement the framework must be extracted. do.

Hereinafter, with reference to the accompanying drawings will be described the structure and operation principle of the Internet search system according to the present invention. Figure 2 shows the overall configuration for the Internet business framework as a general component.

3 is a block diagram showing an outline of a search system according to the present invention. As shown, the entire system is largely divided into three areas: a client side, a server side, and a virtual space to be associated with the present system. In the exemplary diagram of the present system, the conceptualization of the virtual area is described in detail as a shopping mall in view of the e-commerce product search system, but this may be changed according to the application field of the Internet search system according to the present invention.

In addition, the server side includes a management division 11 composed of a seek manager component and a hot-issued component, an affiliate gatherer component and a meta information collector. Infra Division including information gathering division (12) consisting of a component (Meta Gatherer Component), a regular information gathering component (Regular Gatherer Component), and a database base service component ( 13).

On the client side of the system, a user component is provided to the user through a display device such as a monitor connected to the client computer in response to the request of various client users, and the result of information exchange using the communication means with the server. That is, it receives a user's request and queries each component. At this time, the types of request and the corresponding components are shown in [Table 1] below.

Request Component Search Request for Information Seek Manager Search for Hot Issue Information Hot-issue Data retrieval request from affiliate search engine Affiliate gatherer Rebuild Request Meta gatherer Scheduling Request Affiliate Gatherer, Regular Gathering, Hot-Issue

On the other hand, the function of each component on the server side is as follows. First, let's look at the management division (11).

The Seek Manager Component receives the Seek Request from the client through the communication means and sends it to each of the information gathering components (Affiliate Gatherer, Meta Gatherer, and Regular Gatherer) of the later information gathering division 12. Pass a seek. At this time, Query :: Query means information exchange with meta gatherer and regular gatherer, and Query :: Affiliated means interfacing with affiliated gatherer. The search results (in this example, product information) provided through each interface are sent to the user component of the client computer.

The Hot-Issue Component receives a Hot-Issue Request from a client transmitted through a communication means and outputs popular and new information. In addition, the popular & new information is regularly updated according to a schedule provided from the user component. At this time, Query :: Popular exchanges search information for popular products, Query :: News exchanges search information for new products, and schedule is an update schedule from a user component. It means the interface used to receive schedule.

We look at the Gathering Division (12). The information collection division 12 collects commodity information from three kinds of information sources. That is, product information is collected from the main internet business site (Major Biz Site), affiliated Internet business site (Affiliated Biz Site), and all range of Internet shopping malls. First, the Affiliated Gatherer Component receives the search request of the search manager component according to the user's request and requests the user search request to the affiliated system using the same search system. ) To perform the search. It also retrieves the federation system's information and updates its database on a schedule. In this case, Seek :: Seek is an interface for exchanging information according to a search request of an affiliated system from the search manager component, and Schedule is an interface for exchanging schedule information of user components provided from a client computer. do. It also includes the ability to perform non-repudiation of transmission and reception between exchange parties and authentication such as tampering, forgery and eavesdropping on sensitive information such as contract data of affiliated sites. This authentication can be basically performed according to the X.509 certificate format and digital signature algorithm, and the functions provided by the product can be used for existing commercialization such as SSL.

The Meta Gatherer Component collects information from all Internet search systems. In particular, it can perform functions for user training. That is, through the Seek :: Seek interface, information exchange between the search manager component and the search conditions is performed, and the database is updated according to the user's request through the Rebuild interface. .

Regular gathering component (Regular Gatherer Component) regularly collects information from the main search system according to the schedule (schedule) information provided from the client-side user component. The retrieved information is also updated in the database according to the schedule.

The Infrastructure Division 13 includes a DB Component, an Access Control Component, and all Infrastructure Sources (JAVA, EJB, CORBA) that contain product data information. It is composed. The DB service component is responsible for searching in local search engines and updating the database. The access control component has a matrix for determining access permission according to the user's level and the access object's level to determine the access permission of various users. In addition, when a shopping mall is conceived as a representative example of an internet business site, a conceptual framework of product information is largely composed of three entities (or contents). The first is the source of information. The source of information is further divided into three categories. It consists of producer information, commodity seller information and other information representing information on the main products and companies. The second entry represents basic information. Content information indicating the name of product, name of brand, price and function, sale price, delivery and event ) And sales-valued information and value-added information for the seller. Third, the type information indicates the country of production, and in the case of books, the technical field. Such goods information can be actively created according to a conceptual framework.

On the other hand, Internet business sites in the cyberspace can be classified into three categories. It can be divided into an affiliated Internet Business Site, a Major Internet Business Site, and all kinds of Internet Sites. In the present invention, the shopping mall is described as a typical example of such a business site. First of all, an affiliate internet business site is a shopping mall that uses the same data formats and protocols, has more reliable information, and can reduce the time required to retrieve information. In the main internet business site, the regular gathering component collects product information periodically from the main shopping mall according to a schedule defined by the user component of the client side computer. Finally, all kinds of business sites represent providing all the information that exists on the Internet. If the user is dissatisfied with the local search through the regular information gathering component or the affiliate information gathering component, the user can use the Meta Gatherer Component to display all of the cyber space. Information can be collected from the shopping mall. In this case, the user may regenerate information of the database through the rebuild interface of the meta gatherer component.

As described above, the Internet search system according to the present invention includes three categories (Managing Division, Gathering Division, and Infra Division) and eight components (user component, Seek Manager component, Hot-issue component, Affiliate Gatherer component, Meta Gatherer). component, Regular Gatherer component, DB service component, and Access Control component. The system is expressed in UML (Unified Modeling Language), which is effectively used for modeling large and complex systems.

As described above, the present invention can meet the demand for the production of high productivity and high quality software from the software market, and has the effect of enabling the user's search training.
