CROSS-REFERENCE TO RELATED APPLICATION 
     This application is a continuation-in-part of U.S. patent application Ser. No. 13/291,064 filed Nov. 7, 2011, now pending; the disclosures of which are hereby incorporated by reference in their entirety. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates generally to a method for granular tagging of multimedia content in a connected network, and more particularly, to a system that has an ability to add meaningful contextual and personalized information to the content in a granular fashion. 
     BACKGROUND OF THE INVENTION 
     With the growth of connected infrastructure, social networking has become more ubiquitous in everyday lives. A large part of our lives is being dictated by online or otherwise accessible content, and how this content is influenced by the tools and the network that connect us. Recent examples include the changes in platforms like Facebook where they are using services like Spotify to deliver content to match people&#39;s preferences, partnership of Netflix with Facebook to make their content repository more ‘social’, Hulu&#39;s existing social media tools, and other similar services. 
     While the above attempts are steps towards making content more relevant for classification, these still don&#39;t address a few fundamental issues: (a) how to pin-point specific areas in a content (video or audio) file that could highlight the usefulness of the content in a particular context, (b) some indication of the “True” reactions of individuals, groups of individuals, or a large demography of people to a particular content, or a specific area of the content, (c) a method, or platform to make such granular tagging, rating, and search of content happen in a generic and scalable way. 
     In light of above, a method and a system for a scalable platform is provided that enables granular tagging of any multimedia or other web content over connected networks. The method of the invention provides an ability to go in much more granular within a content and enable a way to add meaningful contextual and personalized information to it, that could then be used for searching, classifying, or analyzing the particular content in a variety of ways, and in a variety of applications. 
     OBJECTS OF THE INVENTION 
     It is a primary object of the invention to provide a system for tagging the content based on the individual and personal cues of the users. One example of these cues is emotional profile or emotional score of the users. 
     It is a further object of the invention to provide a method for tagging a multimedia content in a granular manner. 
     It is still a further object of the invention to provide a system that provides a uniform way of continuous and granular tagging of the multimedia content via individual cues, emotional profiles, or emotional scores. 
     A further and related object of the invention is to provide a method of tagging the content with an instantaneous Emotional Score, an instantaneous Emotional Profile, or an individual cues score based on a specific user&#39;s reaction and at a specific time stamp of the content.

     DETAILED DESCRIPTION OF INVENTION 
     In the following detailed description of embodiments of the invention, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of invention. However, it will be obvious to a person skilled in art that the embodiments of invention may be practiced with or without these specific details. In other instances well known methods, procedures and components have not been described in details so as not to unnecessarily obscure aspects of the embodiments of the invention. 
     Furthermore, it will be clear that the invention is not limited to these embodiments only. Numerous modifications, changes, variations, substitutions and equivalents will be apparent to those skilled in the art, without parting from the spirit and scope of the invention. 
     Nowadays with the increase in use of social networking and multimedia content repository, the content is rated based on the individuals liking and disliking of the content. Typically most rating and tagging of content are limited to the option whereby user manually enters the feedback either in form of “like” or “dislike”. The present invention provides a system and method that includes individual&#39;s cues, emotional scores or profiles to tag a multimedia content in a granular manner. The system combines individual cues score, emotional profile or emotional score of the user in a social networking set up to make a more powerful impact on the user&#39;s consumption habit. The present invention further extends the concept of individual cues score, Emotional Score or Emotional Profile tagging of content to a more granular level within a specific content and provides a method and a system to achieve this process in a uniform way, including ways to use such tagging for various methods of analytics and monetization models. The inclusion of individual cues scores, Emotional Scores or Emotional Profiles adds a very unique behavioral aspect to content that may then be used for searching, analytics and various kinds of monetization models for the particular content. The individual cue scores, Emotional Score or Profile is a combination of the emotion, behavior, response, attention span, gestures, hand and head movement, or other reactions or stimuli of the user collected through the sensors available in the client devices and then processed. 
       FIG. 1  illustrates a schematic representation of interacting system for individual cues score, Emotional Score or Emotional Profile based content tagging in connected network in accordance with an embodiment of the present invention. The system comprises of a plurality of (P( 1 ), P( 2 ), . . . , P(N)) connected to each other in a network through their respective client devices: client device  1   116 , client device  2   112 , and client device N  102 . The client devices  102 ,  112  and  116  are configured with a server in the cloud network  106  that is having a multimedia repository containing content  108  that are accessible by the client devices of the users. The content A  108  is accessible by the different users in the network through their respective client devices  102 ,  112  and  116 . The client devices  102 ,  112  and  116  have a module that has an inherent ability to continuously capture some critical auditory, visual, or sensory inputs from the individuals. This module is a functionality that may be a combination of the available sensors in the client device (camera/webcam, microphone, other sensors like tactile/haptic etc.) and the available processing modules present in the client devices. The client devices  102 ,  112  and  116  capture these inputs as they change in response to the individual&#39;s reaction to viewing of content A  108  that is part of connected media repository in cloud network  106 . The individual cues score, emotional score or emotional profile generator  104  of client device N  102  generates the individual reaction, individual cues score, or emotional score of the user as a result of watching the content. The individual cues score, emotional score or the emotional profile of the user N associated with the content is then used to tag the content A  108  in form of CT_PN_A. Similarly the individual cues score, emotional score or reaction of the user  1  and user  2  is also generated by their respective individual cues score generator or emotional profile generator  114  and  110 , and their scores are tagged to the content in form of CT_P 1 _A and CT_P 2 _A. As a result of this the content A  108  that has been watched by n number of users, and the individual reaction, individual cues score, or the emotional score (CT_P( 1 )_A), CT_P( 2 )_A, . . . , CT_P( 3 )_A) of each user as a result of watching the content is tagged to the content A  108 . The individual cues score or the emotional score tagged to the content is then stored in the cloud network as an update on the individual cues profile or the Emotional Profiles of the users P( 1 ), P( 2 ), . . . P(N). Alternatively, the client devices need not generate and send individual reaction, individual cues score, or the emotional score to the cloud or server, and may instead transmit data (e.g. auditory, visual, or sensory inputs from the individuals) to one or more servers which process said data to create the individual cues score or the emotional score and update the individual cues profile. 
     In an embodiment of the present invention, the content A  108  tagged by the individual cues scores, Emotional Scores, or Emotional Profiles of a number of users may be used in multiple ways to increase the relevance of the content on an application specific, user specific, or delivery specific contexts. 
     In an embodiment of the present invention the client device  102  comprises of a single module or a plurality of modules to capture the input data from the individual, to process the input data for feature extraction and a decision phase for generating the profile of the user. Some examples of these input modules may be webcams, voice recorders, tactile sensors, haptic sensors, and any other kinds of sensory modules. 
     In another embodiment of the present invention, the client devices  102 ,  112  and  116  include but is not limited to being a mobile phone, a Smartphone, a laptop, a camera with WiFi connectivity, a desktop, tablets (iPAD or iPAD like devices), connected desktops or other sensory devices with connectivity. 
     In another embodiment of the present invention, the individual cues score, emotional profile or emotional score corresponds to the emotion, behavior, response, attention span, gestures, hand and head movement, or other reactions or stimuli of the user. 
       FIG. 2  shows an exemplary illustration of granular tagging of multimedia content in accordance with an embodiment of the present invention. The example illustrates a method that enables more granular tagging of a multimedia content by the different users. The example shows an episode of a TV show  204  that is 24 minute long that has to be tagged with the emotional score in a granular manner. The episode of TV show  204  is a part of content library  202  or connected repository. The users connected in the network have an access to the content library  202  through their respective client devices, and the content library  202  consists of various channels such as Netflix/Hulu/ABC that provides a link to various multimedia contents available online. When the user watches this multimedia content, the system tags the content by his reaction or emotional score at regular intervals. The example shows a TV show  204  that has to be tagged based on emotional score in a granular manner. While the TV show  204  is being watched by the user, the content is being tagged with the emotional score of the user watching the TV show  204  in a continuous manner. The TV show  204  is divided into number of time segments, for instance scene  1   206  is for time t=0. The emotional score of the user associated with scene  1  is E 1 . Similarly scene  2   208  is for time interval t=4 min and the emotional score associated with that particular time is E 2 . Thus, the tagging of the TV show  204  results in a number of tags that are associated with the exact time stamp of a particular segment. At the end of the tagging the TV show  204  now has several reactions or Emotional Score tags that are associated with specific time segments of the show. 
     In an embodiment of the present invention, the content  204  to be emotionally tagged is divided into a number of time segments, the segments being equally spaced. When the content  204  is tagged by the emotional score of a large number of users, the average emotional score for a particular time segment of the content  204  may be created. This in turn provides a unique way to classify different part of a TV show with very useful information about the user&#39;s reactions or Emotional Score tagged with respect to time segment of the TV show. In another embodiment of the present invention the tags may be individual cues of specific users that may include attention span, gestures, head and hand movements and other sensory inputs given by the users while watching a specific content. 
       FIG. 3  illustrates a flow diagram depicting the method for tagging the content in a granular manner in accordance with an embodiment of the present invention. In an embodiment, the method include following steps: Step  302 : The online media content is stored in multimedia repository which is connected to the server in the cloud network. The multimedia repository being configured to the server has an ability to share the content in the networked environment. Step  304 : The plurality of users are connected in the network with each other and to the multimedia repository, and thus have an access to the content in the repository. Step  306 : When the user accesses the media content, the user express their feelings in form of individual cues or emotions. These individual cues or emotions are captured by the module present in client devices that generates the individual cues score, emotional score or emotional profile of the user associated with the content being viewed by the user. Step  308 : the generated individual cues score, emotional score or emotional profile of the user is tagged to the content. The individual cues score, emotional profile or emotional scores are generated in a continuous manner, and for a particular segment of the content, the score corresponding to that segment is tagged. This results in granular individual cues or emotion based tagging of the video content. Step  310 : The granular tagging of the content is done by specifically tagging the individual cues score or emotional score of the user with respect to the content being watched. Thus, the content is tagged with the individual cues score or emotional score of a large number of users. Step  312 : After generating the individual cues score or emotional score of the user associated with the media content, the granular individual cues or emotional tagging of the content is shared in the central repository. Thus, the content is having a tag from a large number of users who have watched the content. Step  314 : The granular individual cues score or emotional score of the content is then used to characterize the media content. 
     In an embodiment of the present invention, the tagged information may be used in multiple ways to increase the relevance of the content on an application specific, user specific, or delivery specific contexts. 
       FIG. 4  illustrates a user interface showing the concept of granular individual cues or emotion based tagging of multimedia content in accordance with an embodiment of the present invention. The interface  402  shows an output of the module that detects instantaneous reaction, individual cues score, or Emotional Score in a system of the invention. The interface  402  comprises of various regions that shows the outcome of the granular individual cues or emotional tagging of the multimedia content. The region  406  provides the details of video content that has been viewed by the user and is tagged thereafter. The region  406  provides the content details along with metadata that links the content to its source, and the rating given by the user with its intensity and the rating detected by the system through its module. The interface  402  shows the output to the Emotional Score generator module for a specific content (“Epic Chicken Burger Combo” (a YouTube video)). The user&#39;s reaction on watching this video is generated by the Emotion Detection module  104 . The reaction may be based on a variety of sensors (webcam, voice recording, tactile or haptic sensors, or other sensory modules). The instantaneous Emotional Score of the user is generated as a function of time as shown in region  404 . The time axis is synchronized with the time stamps of the content (“Epic Chicken Burger Combo”). The instantaneous score is the normalized Emotion displayed by the user and may have a number of different emotions at any given instance. The graph in the region  404  provides the users emotional score while viewing the content in a continuous granular manner with respect to different time segments. The interface  402  further comprises of a region  408  that provides a D-graph displaying the average value of the emotional score of content  406  and a region  410  that displays a D-graph showing the peak values for the emotional score that has been generated while the user had watched the content  406 . 
     In an embodiment of the present invention, the intensity of the detected emotions vary from the range of 0 to 1 and the different types of emotions used to predict the behavior of the user may be one of 7. The detected emotional state includes Happy, Surprised, Fearful, Normal, Angry, Disgusted, and Sad. 
     In another embodiment or application, the different emotions may be a smaller subset and may have scores in a different scale. This provides a method of tagging the content with an instantaneous Emotional Score based on a specific user&#39;s reaction and at a specific time stamp of the content. Thus, a uniform way of continuous and granular Emotional tagging of any content may be done. In another embodiment of the present invention, the tags may be individual cues scores instead of Emotional Scores. These individual cues scores may include attention span, gestures, head and hand movements and other sensory inputs given by the users while watching a specific content 
     In another embodiment of the present invention, the granular tagging of a variety of content may be done by a large number of users. The granular emotional tagging may then be used to provide a characteristic feature to large multimedia repositories that may further be used in multiple ways to characterize the content in a very granular manner. 
     Once, there is a uniform method of granular tagging of a content repository as described above, there are numerous applications of using the content tagged in the above fashion. Some of these applications are described below, and other related applications are readily apparent to the person skilled in the art based on the ideas described herein. 
     In an exemplary embodiment of the present invention, the granular emotional tagging of the multimedia content is used to identify the segment which is of concern to the users. The graph of emotional score with respect to time  404  on the reaction of content  406  being watched is used to identify the time segment of interest to the users. For instance, the different time segments of the content  306  are analyzed to find out the scene of interest, based on a query that asks to identify the segments of the video that have displayed the Emotion “Anger”&gt;0.4. This brings out the two identified segments as shown in region  412 . These kinds of queries may be generalized over a whole set of videos comprising a content repository like Netflix, or YouTube videos. 
     In another embodiment of the present invention, the system of the present invention is used to identify specific segments of videos that have displayed the highest time averaged specific Emotion (say, “Happy”), or specific segments from a repository that have scored (averaged over all users) a score of “Surprised&gt;0.6” 
     The method of the present invention may be used to create Movie Trailers for audience based on some initial feedback from a focus group. The system may be used to pick a given set of segments with the same video of content that have scored, say “Happy&gt;0.5”, averaged over all users, or all users in a specific age demography. The selected particular segment may be used for creating a movie trailer. 
     In an embodiment of the present invention, a method for analyzing a context or an event is provided. This analysis results into a system generated feedback report which include amongst others: user&#39;s emotion reactions to the context or event, user emotional profile, emotion vector etc. The user&#39;s emotions while interacting with the context or event is captured in form of user&#39;s sensory or behavioral inputs. While interacting with the context or event, the users leave their emotional traces in form of facial or verbal or other sensory cues. The client device captures various sensory and behavioral cues of the user in response to the context or event or the interaction. 
     The captured sensory and behavioral cues are mapped into several “Intermediate states”. In one of the embodiments of the invention these “Intermediate states” may be related to instantaneous behavioral reaction of the user while interacting with the “Event”. The intermediate states mark an emotional footprint of users covering Happy, Sad, Disgusted, Fearful, Angry, Surprised, Neutral and other known human behavioral reactions. The behavioral classification engine assigns a numerical score to each of the intermediate states that designate the intensity of a corresponding emotion. The system also optionally applies a second level of processing that combines the time-aligned sensory data captured, along with the “Intermediate states” detected for any sensors as described in the previous step, in a way to derive a consistent and robust prediction of user&#39;s “Final state” in a time continuous manner. This determination of “Final state” from the sensory data captured and the “Intermediate states” is based on a sequence of steps and mapping applied on this initial data (sensory data captured and the “Intermediate states”). This sequence of steps and mapping applied on the initial data (sensory data and the “Intermediate states”) may vary depending on the “Event” or the overall context or the use case or the application. The Final state denotes the overall impact of the digital content or event on the user and is expressed in form of final emotional state of the user. This final state may be different based on different kinds of analysis applied to the captured data depending on the “Event”, the context, or the application. 
     The final emotional state of the user is derived by processing intermediate states and their numerical scores. One way of arriving at the Final State may be done in the following way. For each time interval (or the captured video frame) each Intermediate State data goes through a statistical operation based on the instantaneous value of that Intermediate State and its average across the whole video capture of the user in reaction to the Event. 
       FIG. 5  illustrates a system  500  for tagging one or more context or event  508 , in accordance with an embodiment of the present invention. An account is created by a user  502  by registering in the system using a client device, wherein an authorizing module  504  is configured to authorize a request coming from the user  502  to access the one or more context or event  508 , where the one or more context or event  508  is a video file, a webpage, a mobile application, a product review or a product demo video. Once the user  502  registers himself, the user  502  can access the one or more context or event  508 . The authorizing means  504  further comprises a user opt-in where user has the option to opt-in for incentive or gamification or other selective options or a panel or can access the one or more context or event  508  directly without selecting any opt-ins. Based on the level of opt-in the user has chosen, different levels of information will be captured and analyzed. For example, if the user chooses to be in a paid Panel, then all users video captured could be stored in the Server/Database storing means  506  in the subsequent steps and used for analysis purposes. If the user chooses Incentives and Gamification option then also user videos could be stored and analyzed. If the user choosed Selective Opt-in, the user may choose not to have his video stored, but the analytics based on user video captured could still be used. If the user chooses No-Opt in then no user video information would be used, user may still give some self reported feedback to the system. These various User Opt-in options could change and mean different things in various embodiments of the system. After registration, when the user  502  interacts with the one or more context/event  508 , the user specific data, application details and content specific data is captured and stored in a storing means or a database or a server  506 . The user specific data comprises captured snapshots, emotional variation of the user  502  and a self-reporting feedback with respect to the one or more context or event. The application details includes number of mouse clicks, number of clicked hyperlink or scroll tab and the content specific data comprises information on media event, session data elapsed event, time stamp and metadata. 
     The system  500  also comprises an application module and a processing means. The application module  510  accesses the one or more context or event  508  and analyzes the captured user specific data, application details and content specific data to generate a user feedback result  512  for a complete duration for which the user has interacted with the context or event  508 . The processing means tags the user feedback result  512  with the context or event  508  in a time granular manner. 
     In an exemplary embodiment, said one or more context or event  508  may be a video file. The application module  510  accesses the video file, and captures the user specific data in real time while the user is viewing the video file. The captured user specific data is then analyzed to generate the user emotional profile or a feedback report. The user emotional profile is generated based on captured video, audio, and other user specific information from the user. The user is also provided with option to give their feedback. The user profile and the context information is then sent to the storing means or the database or the server. The user emotional profile and the feedback report generated by the system is also stored in the storing means. The storing means or the database or the server also include information on the session information and the user specific information. The session information includes media events, elapsed events, emotion vectors, time stamps. The user specific information includes user data, event data, timestamp data, metadata and user emotional profile data. 
     In another exemplary embodiment, the one or more context is a webpage. The application module allows the user to access the webpage. Thereafter, it monitors the user reactions and captures the session information. The captured user reactions and the session information is then analyzed along with the session details to generate a feedback report. The user emotional profile is generated based on captured video, audio, and other user specific information from the user. The application module then transfers the session information along with the user emotional profile and self reporting feedback together with the system generated feedback report to the storing means or server or the database. The session information includes information pertaining to an event, mouse clicks, hyperlinks on the webpage and time stamp data. The user specific information for webpage includes user emotional profile, time stamp and metadata. 
     In another exemplary embodiment of the present invention, the one or more context or the event is a mobile application. The application module configured for the mobile application data performs the function of accessing the mobile application and captures and records the user specific data and application specific data in real time to analyze the user specific data and the application data to generate user feedback result. The user emotional profile is generated based on captured video, audio, and other user specific information from the user. The application module transfers the context/application profile data in the form of mobile application generated data, user emotional profile, self reporting feedback report and the system generated feedback result to the server or the storing means or the database. The context/application profile data includes the user information, event, application information and timestamp data. The user specific information includes user emotional profile, emotional vector, timestamp and metadata. 
     In another exemplary embodiment of the present invention, the one or more content is a product review or a product demo video. The application module first accesses the product review or the product demo content. The application module monitors or captures the review session, the user reactions captured with video and/or audio, and analyzes the review session data to generate the system feedback report. The user emotional profile is generated based on captured video, audio, and other user specific information from the user. The application module then transfers the product information, user specific information, self reported feedback report and system generated feedback result to the storing means or the database or the server.
