Definitions
- This invention relates to entertainment media management systems, and, more particularly, to an apparatus and method that recommends a program to a user based on program metadata and on user profiles.
- a program is a media (most likely an electronic media such as music, television programs, digital video or a tangible item such as a book, compact disc or a live event such as a play, opera, etc.) with validity periods.
- Validity periods define time periods when the program can be delivered to users.
- Program metadata are data that describes a program.
- US Pat. No. 5,410,344 provides a system for selecting programs for presentation to a viewer.
- a neural network is an black box of processing elements with a limited number of inputs and outputs. These processing elements are able to "learn” by receiving weighted inputs that, with time and repetition, can be made to produce appropriate outputs.
- the viewer preference file is accessible only locally on the viewer terminal and contains no implicit ratings so that the value and efficiency of recommendations are limited.
- a terminal offers the ability to assist a viewer in choosing programs for viewing.
- Program recommendations are built from information on frequently viewed programs, persistent profile information and user mood information. This information is interpreted into preferred program indicators and matched with the program metadata to suggest a list of programs.
- the first limitation of this system is that it is not able to make suggestions by correlated profiles of different users.
- the second limitation is that the data gathering and analysis techniques used are adequate for a powerful terminal but not for a central profiling server with millions of users.
- a computer-readable medium is encoded with a method of profiling that collects explicit and implicit data on users related to programs that can be accessed by users and to provide program recommendations to each user.
- the system and method is designed for the server-side and limited resource terminals to set up user profiles from explicit and implicit data simultaneously on a full program schedule database as well as a specific program (e.g., movie) database.
- Schedules on program availability and program metadata are broadcast to or received on request by the user terminal through a communication medium from a central system that contains a network of physical servers (network, application, database server for example).
- a user interactively rates a program or a field of the program metadata
- this explicit rating is sent to the profiling server through the return path and is stored in the user's profile database.
- the profiling server collects information on user tastes with respect to program metadata.
- the profiling server also receives implicit information from user behavior such as user program remind actions, user purchase actions, or user monitoring information. All these implicit ratings complete the profile of each user.
- the recommendation engine of the profiling server evaluates the profile of users with the schedule of programs that are now available and that will be available in the near future.
- the recommendation engine builds recommendations of programs for users.
- the recommendation engine works with several different filtering engines such as a content filtering engine and a collaborative filtering engine and treats one user at a time in each filtering engine. Recommendations are weighted and gathered at the output of these filtering engines and a unique recommendation per program is generated by the recommendation engine for each user. Then the list of program recommendations is stored in the profile of the user. These recommendations are sent to each user terminal on terminal request or by a push from the profiling server. The user can access the resulting recommendations through a user interface that displays recommendations of the best programs for him with different scenarios such as portal, menus, tickers, virtual channels, and lists.
- An object of the invention is to provide a system and method for server-side and limited resource terminals to set up user profiles from explicit and implicit data simultaneously on a full program schedule database as well as a specific program database. Another object of the invention is to generate user program recommendations from the knowledge of the user profile itself, and also from the profiles of its neighbors that have the same tastes.

- the present invention 100 is shown as part of an expanded program delivery system 100 that delivers programs 102 and program metadata 104 from a central server 106 to a user terminal 108 through a network 110.
- the central server 106 can be located at the operator head-end and the user terminal 108 can be an operator set-top box (STB) or the television itself.
- the central server 106 can be integrated into the web and application servers and the terminal 108 can be a personal computer (PC) 114.
- the terminal 108 is a device that displays programs 102 and program metadata 104 to a user and that can interact with the user.
- the terminal 108 is usually a set-top box (STB) or the television set.
- the terminal 108 can also be a wireless device (PDAs, mobile phones, etc.).
- the system 100 operates within the context of a content or service provider system for communicating programs 102 and programs metadata 104 to users 116.
- This system 100 is composed of two parts 118 and 120.
- the first part 118 is the central server 106 that manages and delivers content to the users 116.
- the second part 120 is the user terminal 108 that receives the content and allows the user 116 to interact with the central server 106.
- a content management system 122 manages programs 102 and programs metadata 104 and is synchronized with the content delivery system 124 that sends programs 102 to the network 110, destined to the users 116.
- the content management system 122 also sends program metadata 104 to the profiling server 126.
- the profiling server 126 collects information on programs metadata 104 and on user profiles and stores these data in the program metadata database 128 and in the users profile database 130.
- the profiling server 126 is the main component of the invention: from the collected data, the server 126 builds and delivers program recommendations to each user 116. The recommendations are received by the terminal 108. A user 116 can use different terminals 108 to access its profile on the profiling server 126.
- the profiling server 126 imposes no constraints on the infrastructure of the network 110 if we assume a reasonable bandwidth adequate for the number of users 116.
- program metadata 104 may also be obtained from other sources, such as a ftp xml file or in the media itself, digitally embedded in the content and need not come from the content management system 122.
- a program 102 is described by its metadata 104. Metadata 104 of programs contain a large set of possible fields but only a few subsets of this fields are useful for the profiling server 126 and its recommendation engine 132. A more detailed description of a preferred embodiment is provided as follows.
- Program ID 218 The Program ID 218 uniquely identifies a particular program 102.
- the ID 218 can be an integer (32 bits) or a long integer (64 bits) or a string of bytes not exceeding 2000 bytes.
- Title 208 The title 208 uniquely identifies the main title of the program 102 and is defined as a string.
- the category 210 identifies the media content and media type category of a program 102.
- the media type category defines the type of program 102 such as a movie, song, a documentary, a live event, a software, etc.
- the media type category is defined in one level, which means it is one element of a list of category values.
- the media content category indicates the nature of the content of the program 102. It consists of three hierarchical level categories. For example, a program 102 might have the media content level categories of (1) sport, (2) football, and (3) Arsenal. In the case of an Electronic Program Guide (EPG), the two higher-level fields can be compatible with category fields defined in the Digital Video Broadcasting Standard (DVB). Category fields are defined as strings. Optionally, a unique ID can be added to the string definition.
- Description 220 describes the program 102 in a textual form and is defined as a string. This field is optional for the recommendation engine but useful for the users 116.
- People 212 identify the stars or other persons of interest in the program 102.
- One individual is defined by a people category and by name. Examples of people category are: actor, producer, presenter, famous, etc.
- People categories and people names are designed as strings.
- a unique ID can be added to the string definition.
- Keywords 214 describe the program 102 by a list of keywords. Each keyword represents the content of one part of the program 102. These keywords can be interpreted without the category fields. For example, a keyword might be the "Louvre” in the context of the category "documentary, travel, France". Optionally, a unique ID can be added to the string definition of the keyword.
- Parental rating 216 identifies restrictions regarding who can access the associated program 102. For example, the rating might be "users older than 13". Classification can be by age or based upon content such as violence, language, nudity and/or sex. Parental control attributes are defined as strings. Optionally, a unique ID can be added to the string definition.
- Explicit data 136 is data that are produced by a direct interaction with the user 116. Each user 116 can indicate using a rating scale his preferences on or his reaction to a specific program 102 or a program category or people or keywords. All the user ratings using the rating scale are collected by the profiling server 126 and are stored in the users profile database 130. When a user 116 purchases a program 102 or makes a remind action on a program, these actions are also stored in the user's profile database 130. Implicit data 134 is data that is monitored by the terminal 108 and sent to the profiling server 126. This data 134 is also stored in the user's profile database 130. Implicit data 134 gives information on the viewing habits of the user 116, such as which programs 102 he has watched or used, and the time of day the program was viewed.
- the user profile database 130 is structured as follows:
- the profiling server 126 collects this information. Examples of this information are: nickname, age, zip code, gender, income, etc.
- Processed data This data contains information that is generated by the profiling server 126. For example, this includes program recommendations data generated for each user.
- Aggregated data This data contains data that are extracted and aggregated based on a user profile 138. In this aggregated data, reference to an individual user 116 is lost.
- a submethod 300 acquires explicit data 136 by collecting the user's tastes by means of a rating process.
- the terminal 108 receives program metadata 104 and stores the data locally.
- the metadata is displayed when necessary or requested.
- the user can select a field 214 of a displayed program 200, assign a grade 206 for that field 214 and validate this rating using a validate button such as that on a remote control or touch screen.
- the rating 206 is saved locally on the terminal 108.
- the rating is sent to the profiling server 126 asynchronously.
- a delay can be added before the transmission of the profiling server 126 in order to facilitate the management of the load of the server.
- the profiling server 126 can activate the recommendation engine 132 and immediately returns program recommendations 204 generated from the new rating.
- Fields 222 that can be rated are the metadata 104 available for each program 200 such as title, categories, people, keywords, etc. The same rating process also applies to purchases and reminder requests acquisition.
- a submethod 400 is described for acquisition of implicit data 134 on a terminal 108.
- a time counter is initialized and the system is waiting a user action.
- the user changes a channel.
- an evaluation of the manner in which channels are changed (the "channel zapping") is performed. This evaluation determines the time spent on the previous channel.
- the duration between zapping is evaluated.
- zapping information is accepted and is saved locally 120.
- the method collects a predefined (configurable) number of channel changes/zappings on the terminal 108.
- the method sends this information to the profiling server 126 asynchronously.
- the recommendation engine 132 does not only need to know zapping information but also how long a user has watched a program 200. This information can be built from the zapping information and from the program schedule on the server side 106. However, this additional information can also be built up in the terminal 108.
- this last option has the advantage of reducing the load of the server 106.
- the initial steps 502, 504, 506 of this submethod 500 are the same as that of FIG. 4 and this submethod works in parallel with the main method shown in FIG. 4.
- an evaluation step 508 is added which evaluates the programs 200 watched. This evaluation step 508 determines how long the current program 200 of the previous channel has been watched by the user.
- a time check step 510 if the program 200 is terminated, the time the program was watched is evaluated to determine whether it exceeds the predetermined limit (which is configurable). If so, in a saving step 512, the pro gram- watched information is stored locally on the terminal 108.
- a collection step 514 the method returns to the first step 502 until the number of program 200 watched reaches a maximum.
- a subsequent step 516 after having collected a predefined (configurable) number of watched program information on the terminal 108, the information is sent to the profiling server 126 asynchronously.
- the profiling server 126 includes a core platform system 602 that synchronizes all the subsystems (132,604,606) of the profiling server 126.
- a program agent system 604 receives program metadata 104 from the content management system 122, parses the program metadata 104, converts the program metadata into an internal format as described earlier, and stores the new program metadata in the program metadata database 128. Only the program agent system 604 has to be adapted when a different content management system 122 is connected to the profiling server 126.
- a user agent system 606 is the gateway between the user terminal 120 and the users profile database 130.
- the user agent system 606 receives explicit and implicit data 136 and 134 respectively from the user terminal 120. It identifies, validates and then stores the data in the user profile database 130. If the terminal 120 requests immediate program recommendations built on the newly received data, the user agent system 606 sends the request to the core platform system 602 that activates the recommendation engine 132. The recommendation engine 132 returns the program recommendation list to the core platform system 602 that sends the recommendations to the terminal 120 through the user agent system 606.
- the core platform system 606 controls and manages program and user agent sys- terns 604 and 606, respectively, as well as the recommendation engine 132.
- the profiling system 126 has been designed as a flexible architecture.
- the engine 132 has two working modes. In a first working mode, called a low priority batch mode, the recommendation engine 132 builds new program recommendations for each user when the core platform system 602 informs it that the new program metadata 104 has been added to the program metadata database 128. Depending on the size of the user's profile database 130, the update of each user can take a long time.
- a second mode with a high priority allows the profiling system 600 to respond faster to a request of a user. In this mode, the profiling server 126 brings instant gratification of the user by giving him program recommendations related to the new rating he has sent to the profiling server 126.
- the recommendation engine 132 can easily be adapted to multi-processors and multi-servers architecture with hash coding techniques on users.
- the recommendation engine 132 selects the user it wishes to treat.
- the recommendation engine 132 reads the user profile stored in the users profile database 130. Then the recommendation engine 132 activates different filtering engines 706, 708 and 710 with that profile.
- the recommendation engine 132 supports multiple algorithms and can aggregate the result of the different filtering engines 706, 708 and 710 to a single list of program recommendations.
- the user profile in the user profile database 130 is updated. In order to accomplish this, the weighting coefficients 712, 714 and 716 are added to each respective program recom-
- Coefficients 712, 714 and 716 differ depending on the filtering engine 706, 708 or 710 to which they apply and also depending on the program content category because a filtering engine can be better adapted to one content category than another content category.
- the collaborative filtering engine 708 gives l o better results with the movie content category than with the sport content category.
- the coefficients 712, 714 and 716 can be tuned manually. They can also evolve dynamically by using a feedback adaptive algorithm well adapted to heuristic algorithms.
- the recommendation engine 132 adapts the
- the recommendation engine 132 uses two
- the content filtering engine 706 generates recommendations separately for each user while the collaborative filtering engine 708 finds correlation between the user tastes.
- the collaborative filtering requires bootstrap to start to generate recommendations while the content filtering
- the content of the filtering engine 706 can generate program recommendations as soon as at least one rating has been made by the user 116. Of course, if only a few ratings are given, the customization of the programming recommendations is low.
- One solution consists of providing a default profile when the user profile is first created.
- This default profile can be built on the basic data mentioned under the heading "Program Metadata and User Profiles", available on the user 116 and on aggregated data such as the best or the most rated programs by other users.
- Another more interesting solution is to leave the choice to the user 116 to choose, as a default profile, the profile of a famous person he likes.
- Collaborative filtering has proven useful for movie, book, music or documentaries. Content filtering has powerful availability with news, sport, people, and all strongly categorized items. In the TV context it also fits for periodic programs 102.
- the collaborative filtering engine 708 requires more intensive CPU resources than the optimized content filtering engine 706, the collaborative filtering engine 708 can only be used for a subset of all the programs 102 (e.g. movies, documentaries, music). These two algorithms respectively have proved to be well adapted to item recommendation and are complementary. Nevertheless, the recommendation engine 132 can easily integrate another filtering engine such as a more general social filtering engine 710. Each filtering engine 706, 708, 710 has access to the program metadata database 128 with the explicit and implicit data 136 and 134.
- FIG. 8 describes the internal architecture of the content filtering engine 706, custom developed according to the needs of the present invention.
- the engine 706 is optimized for structured and categorized metadata.
- program metadata 104 with a right validity period are selected in a selection step 810 and indexed in an indexing step 812 for each program field such as "title”, "people", “content category”, and "keyword” used by the engine.
- the engine 706 separates information on user tastes 802, user purchases 804, user reminder requests 806 and use monitoring information 808.
- Each information category 702, 704, 706 and 708 goes through a tuned matching engine for tastes 814 for purchases 816 for reminder requests 818 and for monitoring 820.
- Each matching engine 814, 816, 818 and 820 uses the same algorithm based on static matching rules and non-linear distance estimation between program metadata 104 and user profile fields (defined in user profiles section) but with different rules and distance estimation coefficients for each matching engine. Rules and distance estimation coefficients are based on heuristics built on the knowledge acquired through development, study, and experimentation. Use of matching rules allows the purveyor to find a balance between search (Indexes) and knowledge (Rules), the two main approaches of Al. Details on rule-based algorithm can be found in Charles Forgy, "The Rete Algorithm: A Fast Algorithm for the Many Pattern / Many Object
- a first level 830 aggregates program recommendations built from the user behavior (purchase, remind, monitoring) and a second level 832 aggregates these recommendations with the recommendations built in the taste matching engine 814.
- the matching engines (814, 816, 818 and 820) take into account at what time the program 200 has been watched, reminded and/or purchased. For example, some users 116 watch movies in the evening and news in the morning while others watch news in the evening.
- the recommendation engine 132 tries to follow this time pattern when it generates the program recommendations.
- the content filtering engine 706 generates as output a program recommendation list 906 with a grading 920 on the programs of the list 918.
- the terminal 120 is a device that displays programs 102 and program metadata 104 to a user 116, collects and sends explicit and implicit data 136 and 134, respectively, on users to the profiling server 126.
- a user 116 interacts with the profiling server 126 through the terminal 120 that displays its personal recommendations 204.
- the terminal 120 displays a program description panel 902 with information on one program on top of another.
- Metadata 104 is displayed, including the program title 908, the content category 910 and a list of people 912.
- the rating panel 904 applied on the selected item 914 ("Peter Barton" in this example) and the user 116 can change the grade of the explicit rating 916.
- Program recommendations available for the current user 116 are displayed in the recommendation panel 906.
- Each program recommendation is represented by its title 918 and its grade 920, in this case, one to five stars. Different processes of interaction can also be used.
- the program recommendations 906 can be displayed in a portal, on menus or be received by e-mail.
