A system and method for assigning user preference settings for fields in a category using selected settings for only a subset of the media category fields is disclosed. A subset of fields for a media category is defined. A base setting for each field in the subset of the category fields is established. The base setting may be a weight or preference value. The base setting may be established by the user selecting a base setting or may be a default base setting. Once a user selects the settings for the subset of category fields, a set weight for the fields in the category not in the subset is determined using the base setting. That is possible because the fields in the subset of category fields are chosen from fields that contain aspects and attributes of the other fields.

There is a need for providing a vehicular music replay system that can allow a car user to select a music source appropriate to the user's character or biological condition even from genres unknown to the user, allow even a first music source to be felt suited for the user, and consequently enhance an emotion about encounter with an unknown music source. The system stores music sources to be replayed in music source databases in association with applicable user state data reflecting a user state containing at least one of a user character, mental condition, and physical condition. The system retrieves a music source corresponding to the current user state acquired in a car. During the retrieval, a higher retrieval priority is provided for a music source having a lower replay history in the past.

A method and system for generating playlists for content items is provided. Generating a playlist involves monitoring user interaction with one or more content items as user-content interactions, determining a context associated with one or more user-content interactions, and generating a playlist of the content items based on the user-content interactions and the associated context.

The systems and methods described create a mathematical representation of each of the media objects for which user ratings are known. The mathematical representations take into account the subjective rating value assigned by a user to the respective media object and the user that assigned the rating value. The media object with the mathematical representation closest to that of the seed media object is then selected as the most similar media object to the seed media object. In an embodiment, the mathematical representation is a vector representation in which each user is a different dimension and each user's rating value is the magnitude of the vector in that dimension. Similarity between two songs is determined by identifying the closest vectors to that of the seed song. Closeness may be determined by subtracting or by calculating the dot product of each of the vectors with that of the seed media object.

In an information processing apparatus adapted to determine information, to be presented to a user, as to one or more contents, a calculation unit calculates the similarity between a first search axis, produced on the basis of information associated with the user, for use as a reference on the basis of which to present contents and a second search axis, produced on the basis of information associated with one of other users, for use as a reference on the basis of which to present contents, and a display control unit controls displaying of information associated with contents with reference to first and second search axes detected as being similar to each other.

Embodiments of a computer system to determine one or more annotation items associated with an audio file are described. During operation, the computer system provides an interactive environment in which multiple users listen to the audio file within a time interval. Next, the computer system receives one or more annotation items associated with the audio file from the multiple users. Then, the computer system displays the received one or more annotation items from the multiple users in the interactive environment, thereby enabling the multiple users to provide feedback to a given user in the multiple users.

A system, method, and machine-readable medium are disclosed for the controlled, non-real-time conveyance of digital content for playback. Digital content and associated metadata are marked, rated, categorized, and then converted into encoded digital data. The resulting encoded digital data is transmitted as a plurality of data streams through a communications facility such as a satellite, wireless, or physical network. The data streams are received by a content receiver where they are decoded into metadata and digital content for controlled conveyance and playback. A digital content management module comprising a content selection algorithm compares metadata associated with candidate digital content to a predetermined content selection profile. If the metadata matches predetermined selection parameters of the selection profile, the candidate digital content and its associated metadata are stored in a machine-readable medium for controlled conveyance and playback.

In connection with a classification system for classifying media entities that merges perceptual classification techniques and digital signal processing classification techniques for improved classification of media entities, a system and methods are provided for automatically classifying and characterizing tempo properties of media entities. Such a system and methods may be useful for the indexing of a database or other storage collection of media entities, such as media entities that are audio files, or have portions that are audio files. The methods also help to determine media entities that have similar, or dissimilar as a request may indicate, tempo(s) by utilizing classification chain techniques that test distances between media entities in terms of their properties. For example, a neighborhood of songs may be determined within which each song has similar tempo characteristics.
