A Semantic Space for Music Derived from Social Tags
نویسندگان
چکیده
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 artist and musical genre. We introduce the use of Correspondence Analysis to visualise this semantic space, and show how it can be applied to create a browse-by-mood interface for a psychologically-motivated two-dimensional subspace representing musical emotion.

Timbral Qualities of Semantic Structures of Music
The rapid expansion of social media in music has provided the field with impressive datasets that offer insights into the semantic structures underlying everyday uses and classification of music. We hypothesize that the organization of these structures are rather directly linked with the ”qualia” of the music as sound. To explore the ways in which these structures are connected with the qualiti...
متن کاملAutomatic Hashtag Recommendation in Social Networking and Microblogging Platforms Using a Knowledge-Intensive Content-based Approach
In social networking/microblogging environments, #tag is often used for categorizing messages and marking their key points. Also, since some social networks such as twitter apply restrictions on the number of characters in messages, #tags can serve as a useful tool for helping users express their messages. In this paper, a new knowledge-intensive content-based #tag recommendation system is intr...
متن کاملMusic Mood Representations from Social Tags
This paper presents findings about mood representations. We aim to analyze how do people tag music by mood, to create representations based on this data and to study the agreement between experts and a large community. For this purpose, we create a semantic mood space from last.fm tags using Latent Semantic Analysis. With an unsupervised clustering approach, we derive from this space an ideal c...
متن کاملPredicting High-level Music Semantics Using Social Tags via Ontology-based Reasoning
High-level semantics such as “mood” and “usage” are very useful in music retrieval and recommendation but they are normally hard to acquire. Can we predict them from a cloud of social tags? We propose a semantic identification and reasoning method: Given a music taxonomy system, we map it to an ontology’s terminology, map its finite set of terms to the ontology’s assertional axioms, and then ma...
متن کاملAutotagging Music Using Supervised Machine Learning
Social tags are an important component of “Web2.0” music recommendation websites. In this paper we propose a method for predicting social tags using audio features and supervised learning. These automatically-generated tags (or “autotags”) can furnish information about music that is untagged or poorly tagged. The tags can also serve to smooth the tag space from which similarities and recommenda...
