FoNN: FOlk N-gram aNalysis

Targeting the goals of Polifonia WP3, FoNN contains tools to extract feature sequence data, extract musical patterns, and detect similarity within a symbolic music corpus.

Team: Dany Diamond, James McDermott, Abdul Shahid

FoNN is a software component containing tools to analyse monophonic or polyphonic music corpora in MIDI or ABC notation. The FoNN pipeline first converts corpora to feature sequence representation, then extracts n-gram patterns from user-selectable musical features at multiple levels of granularity. After running these pre-processing steps, FoNN’s music similarity module can be used to detect local-pattern-based similarity within and between music corpora. FoNN includes three search tools, each of which is highly user-customisable. They are: 1. incipit-based, 2. motif-based (finds frequent similar local patterns between scores), and 3. TF-IDF based (ranks TF-IDF vectors for all pattern occurrences in all scores).

SPARQL Anything

SPARQL Anything is a system for Semantic Web re-engineering that allows users to … query anything with SPARQL

Team: Luigi Asprino, Enrico Daga (lead), Justin Dowdy, Marco Ratta, Paul Mulholland

What should a data integration framework for knowledge engineers look like?
Recent research on Knowledge Graph construction proposes the design of a façade, a notion borrowed from object-oriented software engineering.

This idea is applied to SPARQL Anything, a system that allows querying heterogeneous resources as-if they were in RDF, in plain SPARQL 1.1.
SPARQL Anything supports a wide variety of file formats, from popular ones (CSV, JSON, XML, Spreadsheets) to others that are not supported by alternative solutions (Markdown, YAML, DOCx, Bibtex).

Features include querying Web APIs with high flexibility, parametrised queries, and chaining multiple transformations into complex pipelines.

Polifonia Corpus

Online text analysis tool for linguistic interrogation of Polifonia’s multilingual diachronic corpus.

Team: Valentina Presutti, Rocco Tripodi, Arianna Graciotti, Marco Grasso

The Polifonia Corpus is a web tool for interrogating the diachronic collection of corpora of the project, focusing on Musical Heritage (MH) and covering Italian, English, French, Spanish, German and Dutch. Natural LanguageProcessing  techniques have been used to process the corpus and produce automatic morphosyntactic, semantic and MH-specific annotations. Custom APIs have been developed and released to enable domain experts, scholars and music professionals to leverage the annotations produced to perform advanced structured queries on the corpus. The available interrogation capabilities overcome the basic keyword-based search, offering the possibility of querying the corpus by taking advantage of the advanced semantic and MH-specific information encoded in the annotation.

LHARP

Local Harmonic Agreement based on Recurrent Patterns

Team: Jacopo de Berardinis, Andrea Poltronieri

LHARP is a local method for harmonic similarity that emphasises shared repeated patterns among symbolic chord sequences, to accommodate a wide set of applications. Compared to other methods, the local nature of LHARP enables more explorative studies, as it can unveil and establish links when local harmonic patterns are found repeated in both sequences, while retaining global information to a lesser extent. Here, we demo “The Harmonic Network” — a computational tool allowing users to explore music collections by visualising LHARP (harmonic) similarities among tracks, and interacting with the resulting graph to discover nontrivial relationships among authors, composers, and pieces.

Data Wanderings

Data Wanderings is an audiovisual installation created as part of Polifonia, a research project funded by the Europe Horizon 2020 program.

Team: Art Direction: Umanesimo Artificiale, Concept: Filippo Rosati, Alex Piacentini, Data Analysis: Alex Piacentini, Andrea Poltronieri, Jacopo de Berardinis, Creative Coding: Alex Piacentini, Sound Design: Alex Piacentini, edited by: Federica Patti

The sensory journey “Data Wanderings” is a new project of Polifonia. The art installation has been open from Oct. 13 to 28, 2023 in Bologna, Italy.

‘Data Wanderings’ is a synaesthetic installation that challenges the boundaries between art and technology by transforming the rawness of data into a memorable sensorial journey. The audiovisual installation was conceived with the aim of making the user experience a physical simulation of virtual interaction with the mass of data coming from the knowledge graph of the “Polifonia” project.

Data Wanderings invites viewers to embark on a journey through the intricate labyrinth of data, to discover the secret melodies of numbers, and to embrace the creative and informative potential that lies within them.

The Choco database of Polifonia collects data on chords extracted from a series of songs. All song chords are listed in time sequence in a table, converted into a series of notes and their sound frequencies.

In the interactive installation, the eight frequencies of each chord are translated directly into pixels and they create eight mixed patterns to obtain the final “visual noise” patterns. The frequencies also produce a generative soundtrack through FM synthesis to create a crazy digital Orchestrion.

The sphere floating in the center of the screen acts as an interface with visitors and it is generated using the album and singles’ covers from which the chord data was derived. People’s movements are detected with a camera, analyzed and used to influence images and sound by controlling a low-pass filter.
