CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims the benefit of a provisional patent application with the same title, No 62/143509, filed on Apr. 06, 2015 The content of the aforementioned application, including any intervening amendments thereto, is incorporated herein by reference. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    The subject invention is an innovation in the field of online advertising (or Internet advertising), which is a form of marketing and advertising where the Internet is used as the media to deliver promotional marketing messages to consumers. It includes email marketing, display advertising, search engine marketing (SEM), social media marketing, and mobile advertising etc. Like other advertising media, online advertising involves an ecosystem with two, major players: advertiser and ad publisher. 
         [0000]    The advertiser owns and provides the ads to be displayed, and the ad publisher integrates and publishes ads into some online content. Traditional online ad publishers include online search engine providers, the owner of social network sites, the owner of regular web sites, the vendor of mobile apps, etc.
 
The media of advertising industry is rapidly evolving in the past three decades. From the traditional advertising media such as newspapers, TV, and radio, to recently thriving Internet advertising via email, web search engine, online streaming video, the market is starting another big leap—social network advertising and mobile advertising on smart devices. First of all, Internet advertising has a shift to social network advertising. Social network advertising, also called social media targeting, is a form of online advertising that focuses on social networking sites. One of the major benefits of advertising on a social networking site (e. g. such as Linkedin™, Facebook™, Twitter™, Myspace™, Friendster™, Bebo™, Orkut™, etc.) is that advertisers can take advantage of the user&#39;s demographic information and target their ads appropriately. On the other hand, mobile ads on smartphones can appear either through the Web browsers, or within mobile apps. Among many forms of online advertising schemes adapt to the mobile platform, social network advertising is the one that takes advantage of unique features of mobile devices. It gains more attention in the mobile settings as people tend to hang around with their social network friends through the mobile apps in smartphones. There are also vendors who are specialized developing social network apps mainly on smart mobile devices. The examples of such mobile apps include WeChat™, WhatsApp™, LINE™, etc.
 
         [0003]    The targeting approach of advertising is also evolving. Ads are not supposed to send to everyone. To make it effective, the advertiser always intends to send the ads to a targeted population who are potentially interested in the product or service in the ad. Online advertising, in particular, has been walked its way from traditional banner advertising to more effective targeted advertising such as behavioral targeting, which takes into account of user specific traits such as geographic locations, demographics, product purchase history, etc. It works by collecting the Internet user&#39;s behavioral features via anonymously monitoring and tracking the content read and sites visited by a user or IP when that user surfs on the Internet. A further refinement to behavioral targeting is predictive behavioral targeting, where machine learning algorithms overlay behavioral patterns with sampled data to create data-rich predicted profiles for every user. The major disadvantage of behavioral targeting are three-fold. First, this targeting approach requires the acquisitior of user&#39;s historic behavior data, which poses technical difficulty. Second, this approach entails a lag period for the user&#39;s interest. With the assumption that the user&#39;s future behavior is highly correlated with his/her past behavior, it does not consider the fact that the user&#39;s interest may have shifted many times from his/her past online behavior. Third, the user&#39;s privacy is a big concern. Many studies show that this ad targeting approach has negative impact on user experience in terms of privacy leakage. 
         [0004]    Finally, the ad publisher is evolving. Advertisers pay ad publishers for publishing ads at appropriate venues where the corresponding ad targets the right group of people. The online ad publishers mainly take advantage of machine based, automatic behavioral targeting. These publishers are paid via innovative forms of payment mode such as pay per click, pay per call, or social network friends network sharing [1]. With such advertising systems, the advertiser makes the payment to the publisher on any click or phone call generated by people that browse their websites. The online ad publishers, also search engine providers such as Google, Yahoo, and Microsoft, adopt pay per click strategy with success. Typically only the vendor of the corresponding social network, software is able to serve as the ad publisher to insert ads within the app. We argue that this type of ad publisher monopoly should be broken in order to have more diverse, versatile, and potentially more effective advertising strategy. 
         [0000]    The advertisers always seek more effective channels to distribute theirs ads. Of these channels, online advertising is widely used, across virtually all industry sectors and is steadily growing its share. In 2011, online advertising revenues in the United States surpassed those of cable television and nearly exceeded those of broadcast television [1]. Paralleling to the fact that smartphone starts to become mainstream and highly engaged mobile devices in many people&#39;s daily life, the mobile advertising spending is growing its share significantly. According to the leading industry research [2], advertisers will spend $64.25 billion worldwide on mobile in 2015, which is an increase of nearly 60% over 2014 By year 2018, this figure is expected to reach $158.55 billion, when the mobile advertising will account for 22.3% of the total advertising spending. Within the mobile app world, the use of instant messaging mobile apps is growing, and billions of people use alike mobile apps such as WeChat™, WhatsApp™, LINE™ etc. every day. Considering the advertising spending trend and huge market potential of instant messaging mobile apps, it is very promising to propose innovative forms of advertising in this sector. 
         [0005]    There are several instant messaging programs, but only a few programs worldwide that are largely used. With software of several megabytes, users can exchange with each other textual messages, send emoticons, attach pictures and even talk to each other using Voice over Internet Protocol (VoIP) technologies. This invention mainly targets developing a system to deliver precise ad item to instant messaging users and, based on the system, developing a novel business model that applies concept of mesh economy [4]. 
       SUMMARY OF THE INVENTION 
       [0006]    The following presents a simplified summary of the invention in order to provide a basic understanding of some aspects of the invention. This summary is not an extensive overview of the invention. It is not intended to identify key/critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some concepts of the invention in a simplified form as a prelude to the more detailed description that is presented later. 
         [0000]    With the development of above mentioned three areas, including the media of advertising, the ad targeting approach, and ad publisher, the subject invention provides a method, business process and computer program product that can be applied into any type of instant messaging apps for displaying advertisement (ad). We describe the invention details as follows. 
         [0007]    First, the ad is targeting to the real time conversation. When the instant messenger users have a message based conversation in a chat room/group, the system conducts data mining to extract the keywords and topic words from the live conversations. All the captured conversation messages within a time window are either preprocessed on the ad publisher&#39;s terminal, or sent to the backend Big Data processing platform. Preprocessing the live conversation content on client side not only reduce server&#39;s computing burden, but also reduce user&#39;s concern about privacy leakage. With the keywords or topic words as the input to the ad recommendation engine at the backend, the matching ads will be generated from it as the recommendations to display in the live conversation in near real time. 
         [0008]    Second, the system provides three modes for the ad publishing into the real time conversation with in the instant messaging mobile apps These three modes include: (1) the ad is released into real time conversation context automatically; (2) the ad has to get approved by the publisher before released into the real time conversion; (3) the publisher searches the ad database with topic words and/or keywords and find matching ad and release it. The individual instant messenger user acts as the ad publisher to control one of these three modes. In all three modes, the keywords and topic words can be adjusted by the ad publisher and submitted back to server application hosted in the Cloud. 
         [0009]    Third, for all of these three modes, the system supplies a User Interface (UI) to monitor recent released ad logs, and allows the publisher to adjust the score about how precise the ad recommendation was. For instance, the score ranges from 1 to 10. The backend recommendation engine can choose different machine learning models including topic analysis, semantic analysis, and keywords analysis for specific type of advertisement and chat group. Furthermore, recommendation engine can update machine learning model in near real time based on feedback. This feedback channel is claimed as benefit as applying crowdsourcing model into text analysis algorithm. The ad publisher can not only score the ad recommendation accuracy but also adjust the ad associated topics and keywords in the backend ad—keywords database. Furthermore, publisher can input topic and/or keywords to search relevant advertisement that can be released into current conversation context. 
         [0010]    Fourth, the backend Big Data platform employs sentiment analysis and opinion mining for processing data and training model. Different from normal opinion mining application, where one opinion from a single opinion holder is usually not sufficient for action, this invention a real time opinion mining, which focus more on a single opinion holder. This invention applies the concept of crowdsourcing to achieve precise ad delivery and continuously machine learning model training [5]. Current conversation context and advertisement item topic and keywords info will be sent back to backend big data processing system to optimize machine learning model. Therefore, the whole system can recommend more and more precise ad item for target conversation. Furthermore, by using topic trend analysis techniques, this invention can also predict interesting ad contents for a particular chat group. Most important, this invention uses real time conversation content for recommending ad items. Different from existing ad recommendations engines, which use user behavior data and Internet surfing history, this invention deliver precisely target ad items to users in near real time. Meanwhile, those existing traditional ad recommendation engines obviously has latency in delivering ad item to users, who may lost interests or mood on that product already. 
         [0011]    Fifth, the ad server has GUI for small or medium business owner, in-house advertising agent and advertise agents [6]. Currently, there are many third party online advertising platforms, which faces business owner, or in-house agent. This invention has function and GUI for not only business owner and in-house agent, but also all localized advertising agent, who has tight connection with those local business owners. This system also supplies these local small ad agent company a zero cost business to be started. Therefore, more small and medium business owners can put their advertisement in the system. 
         [0012]    Sixth, this invention also makes a novel business model be possible. With this invention, anyone who owns an online chat account can register to be ad publisher and earn certain income. This invention capture and process real tin e online conversation content through publishers online chat account. After processing the real time content, ad recommend engine recommend ad items and the system inject ad items into real time conversation context through publishers online chat account. Or, publishers can manually search in the system based on their understanding about the real time conversation content. 
         [0013]    Seventh, this invention also develops a system that allows ad content to be host on distributed different domain servers. For example, ad content can be hosted on advertiser&#39;s own Web portal. This is important as it could be useful in case instant messenger vendor maliciously block domain name of centralized hosted ad content servers, which share same few domain names. 
         [0014]    To summarize, the subject invention is innovative from following aspects. First takes a novel targeting approach. This approach does not collect the user&#39;s online behavioral data therefore is technically less complex to implement in terms of data acquisition. It captures and analyzes the real time, conversation context that is happening at the very moment. Therefore, this system can deliver precise advertisement content to users at the moment when they have the greatest interest on the topic. It does not track the user&#39;s online behavior and therefore free from ethical issue of violating the user&#39;s privacy. Second, it integrates advanced analytics such as text mining, sentiment analysis to extract ads from the database, and utilizes the crowdsourcing technique to optimize the recombination engine. Third, it creates a novel business model where anyone who owns an online messaging account can register to be ad publisher and earn an income. To walk around possible instant messenger vendor&#39;s against a novel way, which hosts ad content in distributed ad content server having different domain names, is introduced as well.

         [0000]    Introduction to this Invention 
         [0050]    Users of instant messaging clients have become accustomed to asking for information on the same display surface as is their instant messaging graphical user interface. For example, a user may ask for information about one brand of product. The other user in the same conversation context may help him/her by presenting a text, graphic, audio, video and/or URL linkage. These helps are all free. This invention is a system that allow any Instant Messenger user to be able to earn money by presenting precisely ad to his/her chatting partner. This invention is a system allows Instant Messenger user to do zero cost startup business and help improve ad recommendation engine in a crowd sourcing model. It is a kind of mesh economy. 
         [0051]      FIG. 1  is a block diagram illustrating one example of a system for advertising into Instant Messenger chatting context  10 . The system for advertising into Instant Messenger chatting context  10  includes, but is not limited to, devices  102 ,  104 ,  106 ,  108  (only 4 of which are illustrated). The devices include, but not limited to, non-mobile computers, wireless devices, laptop computers, mobile phones, personal information devices, personal digital/data assistants (PDA), hand-held devices etc. However, the present invention is not limited to these target electronic devices and more, fewer or others types of target electronic devices can also be used. The target devices  102 ,  104 ,  106 ,  108  function as client devices in some instances and server devices in other instances. These devices  102 ,  104  can be used by publishers to capture live chat content. 
         [0052]    Web server devices  110  (only one of which are illustrated) is a Web server farm that includes one or more web server that serves communication coming from the Internet  100 . Application server devices  112  process data coming from the front end web servers and send requests to real time data process dusters  114  and data storage devices  118   —  Batch process duster  116  fetch data from data storage devices  118  and process the data and store result back into data storage devices  118 . Data storage devices  118  includes, but is not limited to, Relational Database Management System, NoSQL database, NewSQL database, and other Big Data storage platform. 
         [0053]      FIG. 2  depicts one example of a graphical user interface running on a computing device capable of running an instant messaging client and/or web browser, according to one embodiment The whole GUI  200  holds several tabs including, but not limited to, Promoted Ad  202 , publisher performance statistics  204 , and Settings  206 , etc. Promoted Ad  202  tab includes, but not limited to, components  210 ,  212 ,  214 ,  216 ,  218 ,  220 ,  222 ,  224 ,  226 ,  228 ,  230 ,  232 ,  234 ,  236 ,  238 ,  240 , and  242 , etc. 
         [0054]      FIG. 3  is a block diagram illustrating one example of overall flow chart about how the chat context is processed and ad is recommended. An advertiser may, via a user terminal  108 , register with the website  110  to get permissions to create and set up ad campaigns. Then, an ad is selected based on real time data process  114 , which contains an ad recommendation engine running on. Real time data process  114 , make recommendation based on the data send from publisher&#39;s terminals including, but not limited to  102 ,  104 . The precisely recommended ad will be sent and displayed on users terminals include, but not limited to,  106 ,  107 . 
         [0055]    At  300 , the client application captures the conversation in real time. The real time conversation content can be captured in different ways. For instance, if the device supports a desktop web browser, a browser add-on can be developed to capture all real time internet traffic including instant messenger&#39;s real time conversation content. For another instance, it the device is a smart phone, a background service can be developed to listen on any user interface status changing info including any new message arrived. Once the real time conversation content is captured at  300 . The info can be processed in the next step. 
         [0056]    At  302 , the conversation content may or may not be preprocessed before the into will be sent to the server for getting recommended ad items. For instance, the Preprocess includes, but not limited to, sentiment lexicon generation. At  304 , the processed info is sent to backend system over the Internet  100  in a secure way. At  306 , the client application received recommended ad items from the server side. At  308 , the client application presents ad items on the GUI  200 . 
         [0057]    At  310 , if the publisher setting choose Auto Release  210 , the recommended ad items&#39; info will be presented in columns including, but not limited to,  214 ,  216 ,  218 ,  220 ,  222 ,  224 , and  226 , etc. At  222 , publishers can modify the keywords associated with this ad item. At  224 , publishers can modify the score number, which determine the precise of the recommendation. All modification is sent back to server side for updating recommendation engine model. These features are important as they allow publishers to participate on improving recommendation engine&#39;s machine learning model in a crowdsourcing way. At  316 , the ad items are released into conversation context. 
         [0058]    At  310  if the publisher choose Manual Release  212 , the publisher get opportunity review the recommended ad item. Also, the publisher can modify values at  222  and  224 .
