Voice separation, along with tempo detection and quantisation, is one of the basic problems of computer-based transcription of music. An adequate separation of notes into different voices is crucial for obtaining readable and usable scores from performances of polyphonic music recorded on keyboard (or other polyphonic) instruments; for improving(More)
GUIDO Music Notation is a novel approach for adequately representing score-level music. Based on a simple, yet powerful and easily extensible formalism, GUIDO is realised as a plain-text, human-readable and platform independent format. The key feature of our design is representational adequacy: simple musical concepts can be expressed in a simple way, while(More)
— We present a binary graph classifier (BGC) which allows to classify large, unweighted, undirected graphs. This classifier is based on a local decomposition of the graph for each node in generalized trees. The obtained trees, forming the tree set of the graph, are then pairwise compared by a generalized tree-similarity-algorithm (GTSA) and the resulting(More)
We present and analyze an algorithm to measure the structural similarity of generalized trees, a new graph class which includes rooted trees. For this, we represent structural properties of graphs as strings and define the similarity of two graphs as optimal alignments of the corresponding property stings. We prove that the obtained graph similarity(More)
In this paper we describe the Salieri System, an interactive software environment for structure oriented composition, manipulation, and analysis of music. The system is built on the newly developed Salieri Language, a universal programming language based on a hierarchical model of formal music representation, combining features of traditional functional and(More)
— Most known methods for measuring the structural similarity of document structures are based on, e.g., tag measures, path metrics and tree measures in terms of their DOM-Trees. Other methods measures the similarity in the framework of the well known vector space model. In contrast to these we present a new approach to measuring the structural similarity of(More)
