Description

{Apparatus and method for service trading system based on knowledge search system using questions and answers}

The present invention relates to a service transaction system and method based on question and answer knowledge search.

More specifically, Internet users regularly select experts based on the point scores of each field based on the knowledge search service in which questions are asked through internet portal sites and other users answer them, and certified experts Service retrieval system and method based on Q & A type knowledge search that enables them to commercialize the service that provides professional knowledge service through their own service page to strengthen the expertise of knowledge retrieval service itself and to create the market for service e-commerce. It is about.

In general, the Internet is an open network that can be used freely by applying a common protocol called TCP / IP (Transmission Control Protocol / Internet Protocol) to the other computer that anyone wants to access anywhere in the world. In addition to the delivery, as well as the development of compression technology and the delivery of multimedia information, various services such as e-mail, file transfer, and the World Wide Web (WWW) can be used.

As the use of the Internet is rapidly increasing in Korea and around the world, it is rapidly increasing in importance as a strategic tool for improving efficiency and productivity in all parts of the existing industry, and new business opportunities are continuously created through the Internet. The number of service providers on the Internet is increasing.

In addition, the increase in the use of the mobile Internet (Mobile Internet) using mobile phones, PDAs and IMT2000 services is rapidly increasing, and these services are exploding to match the initial growth rate of Internet users.

In other words, in recent years, the business over the Internet has been progressing to create new and improved business models such as avatar trading and question-and-answer knowledge search service beyond the initial business models such as Internet search, shopping mall, and auction. .

Among these sites, major portal sites are putting a lot of effort into a new service called knowledge search service, which accumulates new knowledge by users' questions and answers through specific knowledge not found in the existing keyword search and natural language search. . This knowledge search service asks, 'Why does Santa Claus wear red clothes?' It's a tool that can satisfy many users' curiosity and easily find difficult expertise by organizing the knowledge that is difficult to find in ordinary search, such as the answer to the question. I am getting it. In the meantime, knowledge search service is becoming a core service for portal site operators, which greatly influences user traffic and the resulting search and advertisement sales.

However, this knowledge search service is launched in a competitively similar manner in most portal sites, and there is a problem that service differentiation does not occur between portal sites. The industry is emerging as a new concern. To this end, there is an attempt to integrate a fixed specialized column commissioned by paying a specialist to a knowledge retrieval service. However, this method had a fundamental limitation that it was difficult to raise the overall level by hiring an unlimited number of experts in the expectation of continuous high cost. Another attempt has been made to service incentives, such as reimbursement of point points earned during the use of knowledge retrieval to cashable points. However, this attempt has some limitations in activating the knowledge search itself by increasing the number of questions and answers, but it has a limit in that it has no direct effect in raising the expertise of knowledge.

An example of providing a service incentive for knowledge retrieval in a somewhat different manner from this method can be found in the related art (Korean Patent Application No. 1020010048861). Based on the traffic generated in the process of sharing knowledge, this technology allows users to access a specific knowledge page and use the information to distribute revenue between the operating company and the information provider for the advertising charges incurred on that page and to place it on the knowledge page. It is a technology that implements incentives to information providers through the distribution of profits between the operating company and the information providers about the purchases of the operating company site itself connected to the page and purchased.

Firstly, this may be somewhat helpful in terms of activating knowledge search by incentivizing more questions and answers, as in the case of switching to monetizable points described above, but the more exposed Revenue is a key structure, so even if the level is somewhat lower than a complete professional answer, you can receive more profit sharing if you answer a lot of questions. There was a limit to the structure that can cause adverse effects.

Secondly, this method is statistical because the operator and the knowledge provider divide the revenue of the banner advertisement and the product sales revenue that are not related to the general service product directly from the expert provided by the expert who answered the specific knowledge page. There was a limit that only a small percentage of sales, known as, occurred, resulting in weak profit distribution. In other words, it was a feeble compensation scheme that differed significantly from the profits that can be obtained when the expert directly provides their own professional knowledge service for a fee.

Meanwhile, among the evolving Internet business models, the e-commerce industry such as Internet shopping malls and internet auctions is continuously growing due to the steady increase of users and the establishment of trust among major large companies. However, the number of users suffering from bankruptcy and fraud by many small businesses rather than large companies is increasing in proportion to its growth. As a result, new efforts are being made, such as introducing an escrow system, which is a trade protection service of payment system linked to a third-party specialized agency, in fear of losing trust of users. However, even without such an escrow system, leading e-commerce companies have secured sufficient trust from consumers, and the operator itself has acted as a trade protection service, and has smoothly relayed product transactions between sellers and consumers.

However, the current e-commerce is mainly dealing with commodities, and the transaction of services is a standardized service that can be said to be a commodity, except for financial services, which are somewhat different in nature, such as hotel reservation, ticket purchase, and voucher purchase. The service is limited to service products such as ticket reservations.

Of course, the movement to provide services on the Internet continues to be provided by individual service providers. However, although services are being provided through e-commerce, it is a system that can easily find and purchase various products in one place such as large-scale internet shopping malls. Has not yet been developed. This slow formation of the service marketplace has resulted in the fact that the distribution channels of the service companies have to be extremely limited, and the service must be built directly, so that the system built for the Internet service of the service product can be covered. Due to lack of sufficient sales, it was not activated enough except for a few websites. This aspect, in turn, aggravates consumer instability, making offline companies more preferred in fear of damage from bankruptcy or fraud. As a result, service transactions on the Internet e-commerce are needed to have a market name. It did not have a basic market size.

On the other hand, if we look at the sluggish aspects of service e-commerce, the auction site shows that the users who are accustomed to the auction are finding themselves as a professional distributor. In the e-commerce aspect of the service that is being developed but the market is not well established, such professional freelancer activities are limited only at the employment site. In other words, in the real offline society, free e-commerce is lacking in that more freelancers have more experts with expertise or skills. Indeed, freelancers with expertise have only been introduced to non-regular workers using job sites, and there is no system to sell their services in the form of e-commerce.

As a result, except for financial services, which are somewhat different in nature, the share of service transactions in total e-commerce is very small. The product bias in electronic commerce is due to the intrinsic differences between services and products. The product is standardized, the price difference by the seller is not large, while the service is difficult to be standardized except in special cases, and the price difference is remarkable according to the level of the company providing the service. In addition, the product is often separated from the producer and the distributor, so even if the distributor's credibility is not known, the same product can be purchased because the producer of the product is the same. In most cases, service companies are directly acted by the company that requested the service, so even in the same service, the customer's satisfaction is different depending on the professionalism and reliability of the service provider. As such, the service is difficult to be standardized, and the variation in service provider's expertise and reliability has been largely difficult to trade in the general form of electronic commerce.

An object of the present invention is to periodically solve the above-mentioned problems, based on the point scores for each field based on the knowledge search service of the Internet users to ask questions through the Internet portal site and answer the other users Question-and-answer knowledge that selects experts and enables certified experts to commercialize services that provide specialized knowledge services through their own service pages so that knowledge retrieval services can be strengthened and market e-commerce is formed. To provide a search-based service transaction system and method.

In general, the application for the service starts with questions and consultations with experts based on the initial questions of the consumer, so the Q & A system has a basic initial environment in the service transaction market.

Therefore, the present invention organically combines the knowledge search service and the service e-commerce market, and goes beyond the simple hobby and the level of fun knowledge search, and promotes the promotion of their services in the knowledge search system with a strong motivation to pursue profits. Provide high quality counseling to maximize the effectiveness, and based on such counseling, users can easily find practical knowledge necessary for real life through the integrated search system, and conveniently find relevant knowledge experts who can trust and apply for related services. Its purpose is to provide an environment that exists.

In addition, the sorting order in the service search may be given an incentive for active professionals by exposing the ranking to the top based on the ranking of the category of the service, or the ranking of the service product determined by the point score obtained by each expert. have.

Then, the plurality of user computers 200 receives the questions from the plurality of users who did not find the desired search results and transmits them to the operator's server computer 400, the operator's server computer 400 proceeds with these questions. Constructed as a separate field in the knowledge database to reflect the ongoing knowledge in the knowledge search.

Then, the plurality of user computers 200 checks the knowledge in progress through the knowledge search, receives the answers from the plurality of users who want to upload answers to the questions, and transmits them to the server computer 400 of the operator. The server computer 400 constructs these answers in a separate field in the progress knowledge database of the knowledge question so that they are reflected as answers in the ongoing knowledge in the knowledge search.

Then, the computer 200 of the plurality of users who asked the question receives the selection for the best answer among the multiple answers and transmits it to the server computer 400 of the operator.

The question-and-answer knowledge search process is repeatedly performed between the plurality of user computers 200 and the server computer 400 of the operator.

In addition, the plurality of user computers 200 may receive a consultation from a plurality of users who access an expert service page that provides an expert service as shown in FIG. 23 separately in the operator's site through the integrated search. The server computer 400 of the transmission, and receives the expert's answer from the operator's server computer 400 to display on the user's screen.

The plurality of user computers 200 receive expert information on service transactions and service product information from the server server 400 of the operator and display them on the screen while the user performs the integrated search. The user receives inputs required for the service application from the users and transmits them to the operator's server computer 400, receives the expert's quotation related information from the operator's server computer 400, displays them on the screen, and agrees to the quotation. It receives the service progress request information and payment information from the operator to the server computer 400 of the operator, and receives the evaluation details and the completion of the service from the user who receives the service and transmits to the server computer 400 of the operator.

The plurality of expert computers 300 are connected to the server computer 400 of the operator providing the portal service in which the question-and-answer knowledge search based service transaction service is established through the network communication network 100, and then the services are provided from the plurality of experts. Basic settings and option settings of the page are received and transmitted to the operator's server computer (400).

The plurality of expert computers 300 receive service merchandise related settings from a plurality of experts who want to commercialize their services after completing the setting of the service page, and transmit them to the server computer 400 of the operator, and the server of the operator. Receives the service consultation request from the computer 400 and displays it on the screen, receives the consultation answers from a plurality of experts, and transmits the request to the server computer 400 of the operator, and requests a service from the server computer 400 of the operator.

The operator's server computer 400 extracts and sorts the combined search results of the knowledge search and the service search according to the search terms or the search sentences received from the plurality of user computers 200, and transmits them to the plurality of user computers 200. Receives the question and answer of the knowledge search received from the user's computer 200 and the selection of the best answer received by building a database indexed to become the base data of the knowledge search, and given the knowledge point score for each activity and It stores by category and transfers the knowledge in the progress knowledge database to the completion knowledge database according to the selection of the best answer to be reflected in the knowledge search and integrated search.

A series of processes such as searching, question and answer, selection of the best answer, and settlement of knowledge points are repeatedly performed by numerous users and accumulated as basic data of knowledge search on the server server 400 of the operator.

At this time, for example, knowledge points can be given to 2 points for 1 question, 10 points for 1 answer, 2 points for the activity reflected by selecting the best answer, and 30 points for the activity selected as the best answer. If the questioner does not select the best answer or receives a report as a bad user due to an inappropriate answer that causes the user's displeasure, a penalty score may be applied and the knowledge point score may be deducted.

In addition, a question-and-answer method is provided in which a knowledge point score is provided to the top respondents by putting knowledge points.

Based on the accumulated data, the server server 400 of the operator regularly selects expert qualifications based on a pre-built expert certification qualification standard, builds a database, and notifies the expert qualifications.

In this case, the criteria for selecting the experts are to calculate the total cumulative score of the knowledge points by category to select all users who are equal to or greater than the expert certification criteria score by category, and the total users whose total cumulative scores of the knowledge points by category are in a certain highest ratio. How to allow, how to calculate the cumulative scores of the last predetermined period of the above-mentioned knowledge points by category and expert certification and knowledge point score received by inputting the expertise score of the answer when selecting the best answer separately from the knowledge point Instead, there is a method to use, and both a knowledge point score and the above-mentioned expertise score satisfy both criteria for each category or a weighted average score of the two scores for each category.

In addition, in the case of the experts who are already recognized in the society, it is possible to supplement the certification process so that professional activities can be performed by immediately omitting such certification procedures.

On the other hand, a plurality of users who have received the expert certification notice are recognized as a plurality of experts in the server computer 400 of the operator at the time of logging in of the expert qualification after receiving the expert certification notice, but the expert is not a professional work but a general user. Except for general searches or questions, any activity performed in a category other than the category for which the expertise has been certified, and the disqualification of the expert, the exception will be recognized as multiple general users.

In addition, the server server 400 of the operator according to the service page settings received from the plurality of expert computer 300 to build the information of the service page of the expert in a database that the expert can operate his own service page To be set.

At this time, the service page of the expert can be easily configured with a few clicks and related information input through the customized service setting mode provided by the corresponding portal site, which is similar to the setting method of the general portal site such as My Page, Group, Mini Homepage, etc. .

In addition, the basic settings in the service page setting process includes the initial screen greetings, history information about his or her career, and the optional settings include the choice of providing real name services and non-real name services, and self-hunting of headhunting. Whether you want to apply for eligible headhunting services, and whether you want to post advertisements for your company or your company on the service transaction page. Will be entered.

In other words, if a non-real name service is selected, the expert exposes his / her real name information only to the operator to prove that it is a reliable service without exposing his / her personal information. It will provide a credit authentication service in the form of a fee.

In addition, when applying for a headhunting service based on the career history information of the expert or the actual career information by the service transaction, additional information such as a resume required for expert headhunting must be input.

In addition, when selecting an advertising service, a professional must input information necessary for providing an advertisement that can raise a keyword advertisement on a service search related to a specialty provided by the specialist at a discounted price for a limited number of times per category.

In this case, the generated advertising costs are initially applied according to the regulations, but when the renewal later, the discount rate may be applied in consideration of the knowledge and service transaction points described later.

The server server 400 of the operator receives the service merchandise-related input information from the plurality of expert computers 300, constructs a database, and indexes the data to be the base data of the service search.

At this time, the input information related to the commercialization is the name of the service to be provided by him, the details of the work, the service period, the number of people, the service progress, the service progress period, the payment terms and the like.

Also, in the process of commodification setting, if an expert wants to form an allied product with homogeneous or heterogeneous experts that are found by using the integrated knowledge search or the separate community function provided by the portal site, the expert may have multiple experts when constructing the service product. If the ID (ID) is assigned to each task and inputted, the operator's server computer 400 stores this information and transmits a request for consent of the combined product to a plurality of experts. It will be stored as a commodity.

When the service product setting is completed, the server server 400 of the operator performs a service on a time table, which is a kind of schedule management function assigned to each expert when the number of persons participating in the service product setting is one expert, and a plurality of experts. Set and save the automatic progress status check function according to the start of the step so as to provide to the user who applied for the service as an additional service.

The server server 400 of the operator establishes an environment in which a user can easily find an expert who wants to order a service transaction in the knowledge search process based on the integrated search of knowledge search and service search.

In this case, if the user does not find the desired expert and already applies for a helper service in the form of receiving service recommendation from the users using the service transaction, the operator's server computer 400 stores the application so that other users can easily search for it. If you set up the environment to be able to do, and if you have made a recommendation answer only to users who have made a service transaction of the category, the details are stored, and the scores of the questioners and answerers for using the helper service are calculated and stored as the point scores of each user. do.

In this case, when the user applies for reverse auction of a service other than the helper service, the server server 400 of the operator stores the service reverse auction application of the user so that the search is provided, and when the experts who search for it answer the service product In addition, this information is stored and provided to the user, and when the user selects a successful bidder based on the credit rating of the applied expert as well as the simple price, the user assumes that the service has already been requested and proceeds with the service transaction.

The server server 400 of the operator constructs and indexes the expert consultation application details received from the plurality of user computers 200 and the counseling response details received from the plurality of expert computers 300, and generates a consultation-related occurrence score. Calculate and build into a database.

And, the server server 400 of the operator stores the service transaction application history when the user applies for the service goods presented in the service page of the expert, transmits the details to the computer of the expert, receives the quotation from the expert computer The quotation is sent to the computer of the user who reapplied, and when the user agrees to the quotation and requests the service to proceed, the information of the progress request is stored and transferred to the expert's computer.

In this case, if the user does not agree with the quotation, a penalty penalty equal to one negative point is charged from the service transaction point of the user.

If the expert attaches the quotation in advance when commercializing the service, the procedure of sending the expert's quotation and the user's request for progress as described above is excluded.

And, the server server 400 of the operator, if the user does not apply for a transaction of the proposed service product and requests a customized service for a specific expert who wants a customized product that is not a standardized service product, which is previously determined, the application Receives and saves the details and transmits the details to the computer of the expert, and if the expert commercializes the ordered service and submits the quotation and responds to the application for the on-demand service, the details are saved and the contents of the new product to the user who applied In addition, the proposed quotation is sent to allow the service transaction to proceed.

In addition, the server server 400 of the operator notifies the expert who has requested the information of the payment situation when a plurality of users request the service to pay the operator to pay the cost by means of credit card, bank transfer, mobile payment, etc. When the service is completed within the specified period, when the user inputs the evaluation and completion of the service through the user's computer, the user stores the information, processes the fee to send the limited service fee to the expert, and generates the points for the service transaction. Points are awarded to the user who applied for the service and the expert who provided the service.

If the expert fails to complete the service within a predetermined period of time, the server server 400 of the operator withdraws the service and refunds the service, and gives the expert a significant penalty score such as negative 30 points.

In addition, in another case in which a penalty score occurs, a method of adding a penalty score in proportion to the number of complaint reports may be added by applying the service complaint to an operator.

In addition, if the transaction is made through a professional company that guarantees sales under the escrow system, the user does not pay the operator, but pays the sales guarantee company, and only the details of the operator's server computer (400). ) Will be processed in the same way as described above, and if a refund occurs, it will be processed by the trade guarantee company for a refund.

And, the server server 400 of the operator, if the user applies for a professional headhunting service for users who are active in the portal site, the information of the headhunting job application, the user of the headhunting among experts in the field desired by the user Extract the service applicant, search according to the user's requirements, select a limited number of people with the best match of the extracted expert's information, finally select the appropriate candidates from the operator's decision, and apply the information to the headhunting service. Transfer to a user's computer.

The operator's server computer 400 periodically calculates experts' knowledge search, counseling, and transaction scores for each category according to a predetermined criterion, and cancels the experts who fail to meet the criteria and stores them in a database. Send authentication revocation information to your computer.

In this case, the criterion of expert revaluation may be based solely on the total cumulative score of the service transaction point scores, or may be based solely on the cumulative score within a period corresponding to the revaluation period. In addition, the scores of knowledge search points of the corresponding categories may be summed and used as a criterion for reassessment.

Next, an embodiment of a question-and-answer knowledge search based service transaction method according to the present invention configured as described above will be described in detail with reference to FIGS. 4 to 16.

4 to 16 are detailed flowcharts illustrating an automatic matching method of a multi-room and a chat site according to the present invention.

First, the expert is selected and certified based on the point score for each category through the question-and-answer knowledge search operation (S100).

In detail, a plurality of users access the operator's server computer 400 through the network communication network 100 to perform a full knowledge search while logging in (S110).

In this case, if the user finds a sufficient answer through the knowledge search, the process is terminated. If the user does not find a sufficient answer, the process proceeds to a process (S130) in which the knowledge question and the answer are made (S120).

That is, as shown in FIG. 9, the user registers a question (S131), reflects the question registered by the operator's server computer 400 in the progress knowledge database 461, and answers the plurality of users who search the question. Register (S132), the user who uploaded the question adopts the best answer (S134), the operator's server computer 400 calculates the knowledge point score and transfers the knowledge to the complete knowledge database (462) (S135). ).

If the user has other questions at this time, the process returns to the above-described step (S110) and repeats the above steps (S110, S120, S130), and if there are no other questions, the process goes to the next step (S150).

Based on the accumulated knowledge data, the server server 400 of the operator converts the knowledge point score of each user category (S150), selects an expert certification qualified person according to a predetermined criterion (S160), and selects the selected user. Notify the fact that the expert has been selected (S170).

In this case, the criteria for selecting the experts are to calculate the total cumulative score of the knowledge points by category to select all users who are equal to or greater than the expert certification criteria score by category, and the total users whose total cumulative scores of the knowledge points by category are in a certain top ratio How to allow, how to calculate the expert by calculating only the cumulative score of the last predetermined period of the above-mentioned knowledge point by category and receive the expertise score of the answer when selecting the best answer separately from the knowledge point, instead of the knowledge point score There is a method to use, and either the knowledge point score and the above-mentioned expertise score are used to satisfy both criteria for each category, or the weighted average score of the two scores is used for each category.

In addition, in the case of the experts who are already recognized in the society, it is possible to supplement the certification process so that professional activities can be performed by immediately omitting such certification procedures.

On the other hand, a plurality of users who have received the expert certification notice are recognized as a plurality of experts in the server computer 400 of the operator at the time of logging in of the expert qualification after receiving the expert certification notice, but the expert is not a professional work but a general user. Except for general searches or questions, any activity performed in a category other than the category for which the expertise has been certified, and the disqualification of the expert, the exception will be recognized as multiple general users.

Now, after authenticating the expert through the knowledge search through the above-described process (S100), the authenticated expert sets up a service page to which he can provide the service (S200).

First, the selected expert connects to the operator's server computer 400 through the network communication network 100 and logs in to the service setting page where he can provide services in a separate space in the portal site ( S210).

Thereafter, the expert sets a basic environment such as a greeting of an initial screen necessary for constructing a service page, history information on his / her career, menu composition, and screen composition (S220).

At this time, if a professional is reluctant to expose his or her personal information and wants a non-real name service, apply for a credit authentication service (S240), and if proceeding to a real name, go to the next step (S250) without the above-described step (S240) (S230). ).

In other words, if a non-real name service is selected, the expert exposes his / her real name information only to the operator to prove that it is a reliable service without exposing his / her personal information. It will provide a credit authentication service in the form of a fee.

After that, if the expert wants to receive the headhunting service based on his / her personal information and the actual career information generated by the service transaction, the headhunting service is requested by inputting the necessary information for the headhunting service (S260), and the subject of the headhunting is desired. If not, the process proceeds to the next step (S270) without the above-described step (S260) (S250).

That is, when applying for a headhunting service based on the career history information of the expert or the actual career information by the service transaction, additional information such as a resume required for expert headhunting must be input.

Subsequently, when a professional wants to register an advertisement related to himself at a discounted price, he / she inputs the necessary information for the advertisement registration service to apply for the advertisement service (S280), and if the advertisement service is not desired, the above-described step (S280). ) Goes to the next step (S290) (S270).

That is, when applying for a headhunting service based on the career history information of the expert or the actual career information by the service transaction, additional information such as a resume required for expert headhunting must be input.

In addition, when selecting an advertising service, a professional must input information necessary for providing an advertisement that can raise a keyword advertisement on a service search related to a specialty provided by the specialist at a discounted price for a limited number of times per category.

In this case, the generated advertising costs are initially applied according to the regulations, but when the renewal later, the discount rate may be applied in consideration of the knowledge and service transaction points described later.

Then, if the expert stores the configuration settings for their own service page, the operator's server computer 400 stores these items and set to be exposed to other users as a complete service page ( S290).

Now, after the above-described process (S200), the authenticated professional sets up his service page, and the expert who wants to commercialize the service using his expertise sets up the commercialization (S300).

First, when the expert sets the commercialization by standardizing his service, the process proceeds to the next step (S320), and if the service is not commercialized, the process proceeds to the next process (S400).

That is, the expert to set up the commercialization is connected to the expert commercialization setting page (S320), and inputs the basic settings necessary for commercialization of the service (S330).

In this case, the commercialization-related input information is the name of the service to be provided by him, the details of his work, the service period, the number of people, the service progress, the service progress period, and the payment terms.

After that, if the expert wants to form an allied product with homogeneous or heterologous experts found by using a separate community function provided by integrated knowledge search or portal site, the process proceeds to the next step (S350), and setting up the related product. If not, go to the next step (S380) (S340).

That is, the expert assigns a plurality of expert IDs (IDs) for each task at the time of constructing the service product (S350), and the server server 400 of the operator stores this information and requests a plurality of experts to agree to the combined product. Send the details (S360), all the requested specialists to enter the information of the agreement to complete the configuration necessary for the combined product (S370).

Then, when the expert completes the product registration application is stored as a formal service product in the server server 400 of the operator (S380).

In addition, the server server 400 of the operator is set so that the service schedule of the product can be set in the time table of the expert, based on the integrated search of the knowledge search and service search, the user in the knowledge search process Build an environment that can easily find a professional to order a service transaction (S390).

In other words, if the number of people involved in the service product setting is one expert, and if the number is a number of schedule management function assigned to each expert timetable (time table) is a function to check the automatic progress status according to the start of the service Set and save to provide as a supplementary service to the user who applied for.

In this case, the sorting order in the service search is configured to give incentives to experts who are actively engaged by exposing to the top ranking based on the expert ranking by category determined based on the point scores acquired by each expert or the ranking of the service products. You may.

Now, through the above-described process (S300), the expert sets the merchandising, and then a plurality of users and a plurality of experts provide a service by consulting the integrated search service of knowledge search and service search and applying for a service product. (S400).

First, a user goes through a process of searching for an expert who provides a service that he / she wants to apply using the integrated search (S410).

That is, as shown in FIG. 10, when the user executes the integrated search (S411) and wants to ask a question through the knowledge search, the process goes to the above-described step (S131). The process proceeds to the next step (S413) (S412), and performs a search by expert or product (S413).

After that, if the user finds the desired expert, the process proceeds to the next step (S440). If the user does not find the desired expert through the integrated search, the process proceeds to the process of selecting the expert (S430).

That is, the process of selecting an expert (S430), as shown in FIG. 11, first if the user uses the helper service, goes to the next step (S436), and if the user does not use the helper service (S432). Go to) (S431).

In this case, when using a helper service, when a user applies for a helper service in the form of receiving a service recommendation from users who have already used the service transaction, the operator's server computer 400 stores the application and easily searches for other users. Set the environment to enable (S436), give a recommended answer only to users who have made a service transaction of the category (S437), calculate the score of the questioner and answerer according to the use of the helper service, and save it as the point score of each user (S438), and proceeds to the next step (S440).

If the user does not use the helper service at this time, if the user applies for the service reverse auction instead, the process goes to the next step S433, and if the service reverse auction is not applied, the process returns to the above-described step S410 (S432).

Subsequently, the user applies for a reverse service auction service (S433), multiple experts participate in the auction including a quotation by putting their service goods (S434), and a successful bidder who wants to report not only the simple price but also the credit rating of the applied professional If it is selected (S435), the user is considered to have already requested the progress of the service and proceeds to step (S486) to be described later.

As such, after the user completes the selection of the expert, the user accesses the service page of the specific expert found by the user (S440), and proceeds to the expert consultation if the user desires (S450).

At this time, the expert consultation process (S450) is shown in Figure 12, if the user applies for expert consultation, the process proceeds to the next step (S452), if not applying for expert consultation to the step (S460) to be described later It goes to (S451).

Then, when the user applies for consultation to the expert (S452), the expert checks the answer (S453), and if the user evaluates the answer (S454), the operator's server computer 400 consults Settle the scores for and give counseling points to users and experts (S455), and proceeds to the next step (S460).

In this way, the expert counseling process (S450), and if the user applies for the service product transaction presented on the service page of the expert, the process proceeds to the process of applying the proposed service (S480), and if not applying the proposed service product on demand Proceed to the process of applying for services (S470) (S460).

At this time, the process of applying for the on-demand service (S470) is, as shown in Figure 13, the user does not apply for the transaction of the proposed service product, and instead of the existing standardized service products, and wants a customized product that is suitable for a specific expert When applying for the on-demand service (S471), the expert who confirmed the application details commercializes the ordered service, submits a quotation with the on-demand service application (S472), and proceeds to the next step (S483) to be described later.

And the process of applying for the proposed service transaction product (S480), as shown in Figure 14, the user checks the details of the presented service (S481), select the proposed service and apply (S482), the matter is applied to the expert Check and send a quotation (S483).

After that, if the user agrees with the quotation, the process proceeds to the next step (S485), and if the user does not agree with the quotation, the process proceeds to the following step (S493) (S484).

At this time, the user agrees to the quotation requesting the service proceeds (S485), the user pays the cost to the operator and the operator's server computer 400 notifies the expert of the payment status (S486), the next process (S490) Go to)

If the expert attaches a corresponding quotation in advance when commercializing the service, the expert's quotation sending step 483 and the user's progress request step S485 are excluded.

After the process of applying for the proposed service (S480), the process proceeds to the post-service transaction management process (S490) as shown in FIG.

This service transaction post-management process (S490), first, if the expert completes the service provision through the normal procedure, and then proceeds to the next step (S494), if the expert does not complete the service provision normally to another step (S492). Passing

In this case, if the expert service is not normally completed, the server server 400 of the operator performs the withdrawal processing and the refund of the service (S492), assigns a penalty score to the corresponding expert (S493), and proceeds to the above-described step (S410). Passing

In this case, another case in which a penalty score is generated is a penalty score added in proportion to the number of complaint reports by applying the same even when a user who receives a service submits a service complaint report to an operator.

When the expert completes the service normally in step S491, the user inputs an evaluation and completion of the service for the service (S494), and the server server 400 of the operator limits the fee to the expert. It is processed to be settled and sent (S495), and the points generated according to the service transaction are given to the user who applied for the service and the expert who provided the service, respectively (S496).

At this time, if the transaction is made through a professional company that guarantees the sale under the escrow system, in the above-mentioned step (S486), the user does not pay the cost to the operator but pays to the company that specializes in the sale and guarantee as described above. In step S495, the remaining amount including the fee of the trade guarantee company is limited and the remaining amount is remitted, and the server server 400 of the operator notifies the user and the expert in the same manner as the steps S486 and S495 described above. In the event that a refund occurs, the transaction guarantee company will process the refund.

Now after the service transaction is made through the above-described process (S400), in the server server 400 of the operator by converting the expert's knowledge transaction scores, consultation scores, service transaction scores by canceling the experts that do not meet the criteria to maintain the service It will be managed (S500).

First, when the user applies for the headhunting service, the user goes through a process of providing the headhunting service through the information (S510).

The process of providing the headhunting service (S510), as shown in Figure 16, if there is no application for the headhunting service from the user to step (S520) to be described later, the user needs to hire a professional to apply for the headhunting service If the case goes to the next step (S512) (S511).

If the user tries to apply for an expert headhunting service for users who are active in the portal site, the user stores the information of the headhunting job application and applies (S512), and the user of the server server 400 of the operator Extract the headhunting service applicant from among experts in the desired field (S513), and by analyzing the comparative analysis according to the user's requirements to select a limited number of people with the best match of the expert's information (S514), finally from the operator judges the appropriate candidate If the user selects them, the information is provided to the user who applied for the headhunting service (S515).

After the process (S510), the server server 400 of the operator calculates the knowledge point score of each expert category for maintenance of the entire service (S520), and calculates the counseling point score of each expert category (S530) ), The transaction point score of each expert category is settled (S540), and the expert is regularly re-evaluated according to a predetermined standard (S550).

In this case, the criterion of expert revaluation may be based solely on the total cumulative score of the service transaction point scores, or may be based solely on the cumulative score within a period corresponding to the revaluation period. In addition, the scores of knowledge search points of the corresponding categories may be summed and used as a criterion for reassessment.

Subsequently, when the expert requalification results in maintaining the expert qualification according to the predetermined criteria, the process returns to the above-described step (S510), and if it is not possible to maintain the expert condition because the criteria are not met, the process proceeds to the next step (S570).

In this case, if it is impossible to maintain the expert conditions because it does not meet the criteria, the server computer of the operator cancels the certification of the corresponding expert (S570), and informs the corresponding expert of the certification cancellation details (S580).

The above process (S500) may be excluded when the professional providing the service and consultation and the users using the service do not need a separate maintenance process by maintaining the service by autonomous and voluntary efforts.

As described above, according to the question-type knowledge search-based service transaction system and method, by combining the question-and-answer knowledge search and the service transaction system organically, experts can proceed professional consultation in accordance with the active motivation to seek profit Therefore, there is an advantage that the expertise of the knowledge search answer is improved. This enhanced answer results in providing a high level of service to users who use knowledge search, and the knowledge search system linked to service transactions can involve the active participation of a large number of experts. have.

In addition, according to the present invention, due to the characteristics of the service that is difficult to be standardized and difficult to measure the reliability of the seller, it is possible to form an integrated market of service transactions through the Internet by activating electronic commerce of services that have not been activated in existing Internet shopping malls or Internet auction sites. There is an advantage. In other words, since experts who have been recognized for reliability through consultation of knowledge search provide services, the initial reliability of service transactions, which was difficult to be formed in the existing e-commerce method, is established, and the commercialization of services is carried out to some extent. It has a self-supporting structure that can achieve standardization, thereby solving problems in service transactions.

In addition, according to the present invention, a small service provider such as a small product sellers with low consumer recognition in internet auctions and sellers participating as side jobs showed more results than existing offline distribution channels through sincere and active customer response. They have the advantage of improving competitiveness across the service industry by providing a service distribution channel that can achieve great results in a different position from providing offline services through active participation. In other words, in order to receive services through the Internet, investment to build a high-quality web service is necessary. Even in the situation where it is difficult to predict the effectiveness, even a small service company or a freelance expert who are difficult to make excessive investments, only sincerity and expertise If you do so, you will be able to achieve as much performance as a large service provider. In addition, this aspect can be a factor in stimulating large companies to provide better services, thereby improving competitiveness in the overall service industry.

In addition, according to the present invention, a user using a knowledge search can search for a more professional answer, can easily grasp the expert of the service related to the knowledge, and can easily apply for the services provided by the experts with confidence. There is an advantage that the satisfaction of the knowledge search service can be improved.

Herein, while the present invention has been described with reference to the preferred embodiments, those skilled in the art will variously modify the present invention without departing from the spirit and scope of the invention as set forth in the claims below. And can be changed.
