wMERA

MERA (Musical Entities Reconciliation Architecture) consist of an architecture highly configurable designed to link music-related datasuources using string comparison techniques and semantic technologies. wMERA is a prototype that implements most of MERA's features, including:

  • Graph navigation exploring alternative forms for each entity.
  • Graph navigation exploring related entities.
  • Configuration of relevancies when applying refinements to a query.
  • Configuration of minimum acceptable values for each type when scoring a result.
  • Blocking function: adaptation of q-gram indexing and TF-IDF.
  • Usage of MERA rdf graph schema
  • Set of comparison algorithms of general-purpose.
  • Set of text standardization functions.

wMERA has been developed in python 2.7 and requires the next packages:

  • rdflib
  • pymongo

The code is organized as follows:

  • Package wmera: Main package. It contains the code of the entity reconciliatory and the modules involved in that process.
    • Sub-package adapters: conversion between different implementations of q-gram indexes.
    • Sub-package controller: code to coordinate query execution with result retrieving.
    • Sub-package graph_gen: code to generate RDF graphs through consuming an interface of a parser that yields model objects. It also contains an implementation of MERA’s graph interface using RDFLib library.
    • Sub-package infrastructure: interface and implementations of the different q-gram indexes.
    • Sub-package parsers: interface of parsers that generate model objects as well as implementations to generate objects of different datasources.
    • Sub-package query_gen: code to generate serialized MERA queries in a JSON model and after parsing another JSON model.
    • Sub-package mera_core: model objects, system interfaces, matching module and string comparison packages.
    • Module facade: code to consume MERA from external apps.
    • Module factory: code to build some specific complex objects.
    • Module utils. Different utility methods.
    • Module word_utild: different utility methods focused in strings.
  • Package apps: scripts that use somehow wmera code: research experiments, graph generation, comparison of tehcniques…
  • Package test: testing code for wmera. Most of these test are integration test, and they expect to be executed in a machine running an instance of MongoDB accessible at localhost:27017.

Documentation of MERA and wMERA are still in progress. Contact with Dani Fernández for any question.
