%description
Provides Bayesian probabilistic methods for record linkage and entity
resolution across multiple datasets using the Comprehensive Hit Or Miss
Probabilistic Entity Resolution (CHOMPER) model. The package implements
three main inference approaches: (1) Evolutionary Variational Inference
for record Linkage (EVIL), (2) Coordinate Ascent Variational Inference
(CAVI), and (3) Markov Chain Monte Carlo (MCMC) with split and merge
process. The model supports both discrete and continuous fields, and it
performs locally-varying hit mechanism for the attributes with multiple
truths. It also provides tools for performance evaluation based on either
approximated variational factors or posterior samples. The package is
designed to support parallel computing with multi-threading support for
EVIL to estimate the linkage structure faster.
