CIDER-LM is an ontology matching system focused on the use of multilingual transformer models. It is inspired by CIDER (Context and Inference basED ontology alignER) but with a completely new underlying technique, design, and implementation.
The matcher has been developed using Python. We use the Maven (Java) framework MELT to wrap the Python command in a Java class for easier packaging and evaluation of the matching system.
The system obtains the label for every class and property and get a fixed length embedding. This embedding is obtained using SBERT multilingual model from the sentence-transformers. These models are trained to obtain pooled embeddings so that similar text (more than one token) is close in the embedding space and the text similarity can be computed using the cosine similarity measure.
For local execution, first install the Python virtual environment with the dependencies and then execute the EvaluateDemoPythonMatcher Java class using Maven command mvn.
Anaconda (conda), Maven (mvn) and Java need to be installed for executing the system locally.
Python dependencies are listed in the ./requirements.txt file. They are automatically installed in the Anaconda virtual environment.
conda env create -f ./environment.ymlconda activate ciderlm-envor copy the virtual environment's command to./ciderlm/oaei-resources/python_command.txt(e.g.$USER/anaconda3/envs/ciderlm-env/bin/python)
cd ciderlm- Compile:
mvn package - Execute:
mvn exec:java -Dexec.mainClass="es.unizar.sid.ciderlm.EvaluateDemoPythonMatcher"
For OAEI evaluation campaign the submission has to be a containerized web server that can perform the match.
- Execute command:
mvn clean install -Djava.net.preferIPv4Stack=true - Python, Java and Maven are installed in a container
- Dependencies are installed (see
pom.xml) -Doption is recommended to avoid network failures in the download.
CIDER-LM is developed by the SID group (University of Zaragoza).
