Definitions

  • This invention relates to a system, a method of operating the system, a server device for use in the system, and to a computer program product on a computer readable medium.
  • Messenger programs are popular because they offer interaction with the user's friends. However, they don't directly support interaction in relation to a joint activity or experience, such as listening to music. Hence, except for chatting, they are programs with a very limited functionality, which are typically used in combination with some other activity, such as gaming or doing homework. Therefore, typically, a user sits behind his PC to chat with his friends and the television is switched on, to listen to music and to watch music videos. If the user doesn't like the music, he can become irritated and switch the TV off (temporarily).
  • Korean Patent Application Publication 2003/0067649 discloses a system for transferring music using a wired/wireless Internet messenger, which is designed to enable a user to work or use a messenger service while hearing a favorite song.
  • the document discloses an instant messenger system which comprises an instant messenger and a messenger database server.
  • a messenger music streaming system comprises a music media server, a music web server, and a music database server.
  • the instant messenger requests the member information, the friend information, and the member certification to the music web server in real-time.
  • the music web server finds out an effect sound and a music source file from the music database server, and sends it to the music media server.
  • the music media server sends the music source file to the messenger database server.
  • This system provides a music sample through an instant messaging program, but does so only in response to a specific selection by a single user.
  • a combined music and chat service is also disclosed in United States of America Patent Application Publication 2006/0224971, which describes a system and method for facilitating discovery and promotion of musical works via an electronic network.
  • the method comprises the steps of receiving the musical works from artists; establishing a virtual room; allowing a user to enter the virtual room and select one or more of the musical works to be played; and allowing the user to chat with a second user within the virtual room.
  • any one or a plurality of a large number of enhancement features that further facilitate the discovery and promotion of the works.
  • This system allows users to choose a musical work and listen to that work together while chatting in a "virtual room". Again, all of the music choices are made by an individual user.
  • a system comprising a plurality of client devices and a server device, the server device being arranged to operate a messaging service, and each client device being arranged to operate a messaging client and being connected to the server device, wherein the server device comprises a messenger component arranged to operate the messaging service, and to identify connected client devices, and a content selector component arranged to access data relating to a plurality of content files, to access a plurality of user profiles, at least one user profile representing a connected client device, and to select a content file, based upon the user profiles of the connected client devices.
  • a method of operating a server device comprising operating a messaging service, identifying client devices connected to the server device, accessing data relating to a plurality of content files, accessing a plurality of user profiles, at least one user profile representing a connected client device, and selecting a content file, based upon the user profiles of the connected client devices.
  • a server device comprising a messenger component arranged to operate a messaging service, and to identify connected client devices, and a content selector component arranged to access data relating to a plurality of content files, to access a plurality of user profiles, at least one user profile representing a connected client device, and to select a content file, based upon the user profiles of the connected client devices.
  • a computer program product on a computer readable medium, the product serving for operating a server device and comprising instructions for operating a messaging service, identifying client devices connected to the server device, accessing data relating to a plurality of content files, accessing a plurality of user profiles, at least one user profile representing a connected client device, and selecting a content file, based upon the user profiles of the connected client devices.
  • a service that allows people to play content files such as music clips while chatting via a messaging service.
  • the system combines on-demand-content, messenger-like functionality, and user profiles into a new service. With this service, a user can chat with his friends (just like Microsoft Messenger TM), and watch music videos, television programs, or listen to music tracks.
  • An advantage of the invention is that the content selection is based on the taste of the people who are connected to the messenger service.
  • the system has commercial opportunities, which may provide additional services to both clients and content providers, or service providers, for example because the people on-line will together pay a small fee for the music to which they are listening.
  • the music selection algorithm operated by the content selector component together with the scoring mechanisms gives feedback to the service provider about the user's music preferences. This forms useful information for the music industry.
  • the music selection can (in part) be influenced by the music industry.
  • the likelihood that a particular music video will be selected can be increased.
  • Another alternative is the use of data mining in the chat rooms by building profiles based on participant profiles and personal tastes, in order for example to provide the music industry with input for targeted advertisement campaigns.
  • the data mining results could be used by the service provider to increase the hit rates/click-through rates of advertisements.
  • the system can also be used to construct playlists for each individual user from the selected music. In this scenario the music can be presented for free, but when the users selects a song again from the playlist, a fee is requested (or he/she is directed to a purchasing service).
  • business profiles can be used to subtly adjust the selection choices, favoring certain content files.
  • the content selector component is further arranged to transmit the selected content file to the connected client devices.
  • this can be transmitted to the connected client devices to be played to those users who are chatting via the messaging client located on their local client device.
  • This transmission can be in the form of streaming data or as a single download.
  • the content selector component is arranged to transmit an identifier to the connected client devices, the identifier identifying the selected content file. This may be because the desired content file is already present on at least one of the client devices, stored on a local storage medium. Alternatively, the piece of music that has been selected may be found at a location remote from the server running the messaging service, and the client devices will retrieve the selected content from that other location.
  • the content selector component is advantageously further arranged to receive feedback on the selected content file from one or more connected client devices, and to adjust future selections accordingly.
  • This feedback mechanism can be used to update the user profile of the user who gives the feedback. It can also be used as a method of creating a user profile for a user who does not yet have one. As the users make further feedback decisions in the future, their new user profile is refined with this data.
  • the feedback can also be gathered (following the obtaining of the necessary permissions as required by law) and used to rate specific content files such as music tracks, which have potential value to actors in the chain such as record companies and television channels.
  • the content selector component when selecting a content file from the content database, based upon the user profiles of the connected client devices, is arranged to access an individual user profile for each connected client device and to generate a community user profile by combining the accessed individual user profiles.

  • the messaging service allows two or more users to communicate with each other.
  • Each client device 10 runs a messaging client in which text is entered.
  • the server 12 runs the messaging service that communicates the entered text to the connected client devices 10, for display locally on those devices 10. This all occurs in real-time.
  • the server 12 manages the connections of the client devices 10 to the messaging service and ensures that the users are identified and if necessary authenticated.
  • the server 12 also maintains a storage function of the various "threads" that are currently being run. Multiple users can be connected, and a single user can participate in multiple "chat" sessions.
  • the embodiment is implemented in a text-based chat service, it can also be used in other services, for example in audio/video chat services.
  • adding background audio/video content is well suited for text-based chat sessions, the present system is not limited to text-based messenger services and can be used advantageously to complement or enhance any messenger services with (further) audio/video feeds.
  • FIG. 2 A more detailed view of the system is shown in Figure 2.
  • Four different users 10 are connected to the server 12.
  • the users are split into two logical communities 16. This means that userl and user2 are chatting together in one community 16 and user3 and user4 are chatting together in a second community 16.
  • the server 12, as discussed above, can handle very large numbers of connected client devices simultaneously, and can process the message traffic in real-time, running multiple concurrent sessions.
  • the server 12 differs from a conventional instant messaging server in that it also has a content selection function, which is described in Figure 2 with reference to music selections, but which could equally be video files or indeed any kind of content that can be streamed or provided as a discrete file.
  • the server device 12 comprises a messenger component 18, which is arranged to operate the messaging service with the client devices 10, and is also arranged to identify connected client devices 10.
  • the messenger 18 could be distributed across several different machines.
  • the server 12 also includes a content database 20 arranged to store a plurality of content files, in this example music videos, and a profile database 22 that is arranged to store a plurality of user profiles, at least one user profile representing a connected client device 12. An initial user profile can be automatically generated, thus allowing new users to seamlessly connect to the system.
  • Access to the content database 20 is managed by a music manager component 24, and access to the profile database 22 and a business database 30 is managed by a profile manager component 26.
  • the example embodiment shown in Figure 2 shows the server device 12 provided with the databases 20 and 22, storing content and user profiles, respectively.
  • the functions of the server 12 are performed with respect to remote or distributed sources of the content and user profiles.
  • the server 12 also includes a content selector component 28 that is arranged to select a content file from the content database 20, based upon the user profiles of the connected client devices 10.
  • the content selector component 28 is arranged to access data relating to a plurality of content files and to a plurality of user profiles.
  • the data concerning the content files and the user profiles are found locally, stored on the respective databases 20 and 22 within the server 12.
  • the selector component 28 could access the data and user profiles from remote data functions and/or from distributed sources of data.
  • the content selector 28, when accessing the user profiles may actually acquire them directly from the client devices 10 as and when the users connect to the messenger 18, rather than storing the profiles locally in the database 22.
  • the accessing of the data about the content files may involve accessing data from multiple sources including files stored on the client devices 10 and/or data stored on proprietary databases or web servers, for example.
  • the selector component 28 is arranged to access an individual user profile for each connected client device 10 and to generate a community user profile by combining the accessed individual user profiles. This is then used to intelligently select a suitable music file from the database 20, which is likely to be well received by the individual users that make up a specific chat community 16.
  • novel matching content could be introduced to the session by content providers, which might also provide a click to buy function. The novel content could be based on mutually positively rated content, or content which matches the most recent taste, and/or mood settings from the users.
  • the files that are stored by the database 20 include metadata that define the contents of the individual music files. This is discussed in more detail below, with reference to Figure 6.
  • the server 12 also comprises the business profile database 30 that is arranged to store a plurality of business profiles.
  • the content selector component 28 can be configured so that when selecting the content file (whether from the content database 20 or from another source), this can be based additionally upon one or more business profiles.
  • the selector component 28 runs an algorithm to select a piece of content based upon an amalgamated profile of all the users in a current community 18. This algorithm can be biased towards certain content files on the basis of the business profiles stored in the database 30.
  • the server 12 can be run on a commercial basis where specific originators of content can pay to have their artist's work chosen by the algorithm run by the selector 28 on a more regular basis.
  • the content selector component 28 if the selected content file is stored locally in the database 20, is further arranged to transmit the selected content file to the connected client devices 10, via the messenger component 18.
  • the content can be provided on a streaming basis, or the content can be downloaded to the client device 10 for playback.
  • the users at the client devices 10 they see nothing more than that they are chatting with their friends and they are supplied with some content (a piece of music or music video) that accompanies their chat session.
  • the content selector component 28 can be arranged to transmit an identifier to the connected client devices 10, the identifier identifying the selected content file, rather than actually sending the chosen content to the client devices 10. This can be used to save bandwidth, if the specific piece of content is already present at the connected client device 10, or indeed if the user is going to acquire the content from another source such as a proprietary service.
  • the content selector component 28 is also further arranged to receive feedback from one or more connected client devices 10 on the selected content file, and to adjust future selections accordingly. As shown in Figure 2, there is a feedback loop marked
  • “getMusic/rateMusic” which allows the users to rate the content that is being supplied to them. This could be in a simple thumbs up/thumbs down manner or could be a more complicated numerical scale, for example.
  • the choices made by the users can be incorporated into the algorithm executed by the music selector 28 and/or could be used to update the user profiles of those making the feedback. Mood-based selection is also possible, on the basis that, for example, first thing in the morning a user does not wish his normal preference for heavy metal to be indulged. This allows a user to temporarily adjust his profile, which can be dropped when a session is finished.
  • An alternative implementation of the same idea would be for the individual user profile to be configured to support one or more moods as sub-profiles. Users can also make explicit music/content suggestions, allowing them to "plug" their own preferred titles.
  • Figure 3 shows an example of how a message sequence chart would look for a simple example of two users chatting in a community 16.
  • the message flow is also illustrated in the system diagram of Figure 2, which shows the names of messages against the connections between specific components of the system.
  • the community 16 is composed of two client devices 10, being userl and user2.
  • the music selector 28 makes a request "getCommunity" to ascertain the client devices 10 that are currently connected in the chat session in which userl (who made the "getMusic” request) is participating. The answer is then returned from the messenger component 18, which is running the chat session, that the current members of the session are userl and user2. This will now be used by the music selector 28 as a basis for selecting a content file to be outputted at the client devices 10 presently within the community 16 that contains userl .
  • "getProfile” requests are made by the selector component 28 of the profile manager 26 for each of the users within the community 16.
  • the profile manager 26 has continuous access to the user profile database 22, and recalls the respective user profiles for the two users, userl and user2. These are then passed to the selector component 28.
  • the selector component 28 also makes a "getBusinessprofiles” request to the profile manager 26, and receives back one or more business profiles.
  • the content selector component 28 is arranged to select a content file from the content database 20, based upon the user profiles of the connected client devices 10.
  • the selector 28 runs an algorithm that applies selection criteria based upon the user profiles of userl and user2, and any business profiles that are used.
  • the selector 28 communicates with the music manager 24 to obtain metadata about the content stored in the database 20, and this is used in conjunction with the profile information to select a music clip.
  • This music file is obtained by the music manager 24 from the database 20 and passed to the music selector 28.
  • the selector 28 then supplies the chosen music file to the connected client devices 10 within the current community 16, being userl and user2.
  • the users have the option to rate the music that is being delivered to them (either streamed or downloaded as a file) and this can be fed back to the selector 28, shown in Figure 2 and 3 as the "rateMusic" message.
  • the content selector 28 can then use this to issue an "updateProfile” message to the profile manager 26, which can adapt the user profiles of those users who participate in the feedback loop.
  • the sequence of messages shown in Figure 3 is terminated by a "goodbye" message when the current chat thread is ended.
  • a chat thread can have multiple participants, not just the two shown in the illustration of Figure 3. In the case when there are more than two participants, a single user leaving a session will not end that session, but it will affect the operation of the algorithm that the selector 28 is running. The user profile of the user that leaves the session will no longer be used to make the content selection, and in a similar fashion, as new members join the chat thread, then their user profiles will be included in the choice of content. A dynamic calculation of the content selection is occurring, as the members of the current community 16 change, caused by users leaving and joining.
  • the method of operating the server device 12 is summarized in Figure 4, which comprises, step Sl, operating the messaging service, step S2, identifying the client devices 10 connected to the server device 12, step S3, accessing data relating to a plurality of content files, step S4, accessing a plurality of user profiles, (at least one such user profile representing a connected client device 10), and finally at step S5, selecting a content file based upon the user profiles of the connected client devices 10.
  • step Sl operating the messaging service
  • step S2 identifying the client devices 10 connected to the server device 12

  • step S4 accessing a plurality of user profiles, (at least one such user profile representing a connected client device 10)
  • step S5 selecting a content file based upon the user profiles of the connected client devices 10.
  • the selected content file is then supplied to the connected client devices 10 in the current community 16.
  • the content selector 28 In relation to the accessing of data relating to content it is sufficient for the content selector 28 to know where the content resides, which might be in a central database, or stored at the client device of a user, or located somewhere on a peer2peer network. In a similar fashion, with regard to the profiles that the content selector 28 accesses, it is likewise sufficient to have the relevant information available at the actual selection time, so users might provide their respective profile when entering a session, rather than the server 12 storing the profiles. It is therefore true that there is no essential need for a central content/profile database located at the server 12.
  • Any distributed and/or centralized content databases that are accessible by the selector 28 can be combined with a central (sponsored) database of content that exists (from for example, a music vendor) and that is interleaved between the content to which the participants have access.

  • User profiles 36 and business profiles can specify scores for each attribute from -5 through 0 (neutral) to +5 in integer intervals. For example, a specific music clip may have, in its metadata 34, the song genre of "modern jazz".

Given is a set C of clips 32 and an attribute A, having values a! ... a n . Initially there is created a probability distribution where each value a, has a chance of 1/n, illustrated as follows:
  • the distribution can be adapted to increase the likelihood that a particular value will be chosen. For example, the chances will be linearly increased/decreased depending on a positive or negative score:
  • the distribution will further be changed by the value for the attribute in the community profile.
  • a value a of an attribute A is selected.
  • the set C of clips is then reduced by removing all clips having a value different from the value a for the specific attribute A. These steps are repeated for the other attributes.
  • a clip is then selected either randomly or based on other factors such as time since last used. This is the clip that will be offered to the users of the community 16.
  • a user can then score the clip, and this is fed back into the decision making process. For instance, by indicating that he does not like this type of video, this particular video, this artist, this music genre etc., the user can change the make-up of their profile 36.
  • the business profiles stored in the business profile database 30 can also be used in the algorithm executed by the content selector 28.
  • the attribute "song genre” may have values: jazz, pop, dance, classic and blues.
  • a business profile for this attribute may be [jazz -5, pop 2, dance 2, classic -4 and blues O].
  • the default distribution for this attribute is:
  • a value for the attribute "song genre" is selected. In this example it means that jazz will not be selected, and that Pop has the highest chance of being selected.
  • the content (such as a collection of videos) is reduced by removing all videos of genres other than the one selected. This algorithm is repeated for all attributes of the community profile. From the resulting collection of videos, a video is selected. This final selection from the shortlist can be made randomly, or based on some other criteria, such as business rules, or the least recently selected.
