Unable to achieve high recall and high precision for the bigger datasets

[Murray1991]

Hello,

In the entity matching step I'm trying to combine different bag models with similarity measures for the dirty dataset "movies" in the data folder.

Unfortunately I'm unable to get high recall and high precision, could you give a good "recipe" to get good results for that dataset?

Thank you

Hi,

you can find an example of how to optimize the performance for the Dirty ER movies dataset here: https://github.com/scify/JedAIToolkit/blob/mavenizedVersion/jedai-core/src/test/java/org/scify/jedai/configuration/OptimizeDirtyMoviesDataset.java . Just make sure you unzip the profiles in the data folder.

Kind regards, George

Hi George, something isn't working as it should. Launching the algorithm, filtering for "F-Measure" string, I obtain the following
