Exploring Mood Metadata: Relationships with Genre, Artist and Usage Metadata
نویسندگان
چکیده
There is a growing interest in developing and then evaluating Music Information Retrieval (MIR) systems that can provide automated access to the mood dimension of music. Mood as a music access feature, however, is not well understood in that the terms used to describe it are not standardized and their application can be highly idiosyncratic. To better understand how we might develop methods for comprehensively developing and formally evaluating useful automated mood access techniques, we explore the relationships that mood has with genre, artist and usage metadata. Statistical analyses of term interactions across three metadata collections (AllMusicGuide.com, epinions.com and Last.fm) reveal important consistencies within the genre-mood and artist-mood relationships. These consistencies lead us to recommend a cluster-based approach that overcomes specific term-related problems by creating a relatively small set of data-derived “mood spaces” that could form the ground-truth for a proposed MIREX “Automated Mood Classification” task.

Exploiting Recommended Usage Metadata: Exploratory Analyses
In this paper, we conduct a series of exploratory analyses on the user-recommended usages of music as generated by 1,042 reviewers who have posted to www.epinions.com. Using hierarchical clustering methods on data derived from the co-occurrence analyses of usage and genre, usage and artist, and usage and album, we are able to conclude that further investigation of user-recommended usage metadat...
متن کاملA Semantic Space for Music Derived from Social Tags
In this paper we investigate social tags as a novel highvolume source of semantic metadata for music, using techniques from the fields of information retrieval and multivariate data analysis. We show that, despite the ad hoc and informal language of tagging, tags define a low-dimensional semantic space that is extremely well-behaved at the track level, in particular being highly organised by ar...
متن کاملHow Much Metadata Do We Need in Music Recommendation? A Subjective Evaluation Using Preference Sets
In this work we consider distance-based approaches to music recommendation, relying on an explicit set of music tracks provided by the user as evidence of his/her music preferences. Firstly, we propose a purely content-based approach, working on low-level (timbral, temporal, and tonal) and inferred high-level semantic descriptions of music. Secondly, we consider its simple refinement by adding ...

متن کاملHow to access audio files of large data bases using in-car speech dialogue systems
Today, a number of in-car speech interfaces to handle large vocabulary are available. We propose an approach that allows accessing audio data on different media carriers and in various formats in a uniform way. This uniformity is achieved by providing an audio data retrieval via metadata. Each audio file is enhanced with machine readable information about several categories (e.g. title, artist,...
