FieldedSDM
UPDATE: FSDM was included in Galago 3.9 release under contrib module.
Fielded Sequential Dependence Model is a retrieval model for effective search of structured documents. It is a generalization of Sequential Dependence Model (SDM) by Metzler and Croft, and Mixture of Language Models (MLM) by Ogilvie and Callan.
All experiments were performed on a test collection for entity search in DBpedia using Galago.
The model is implemented in Java as a Galago traversal. Yet, we provide an implementation of MLM. You can find both implementations in galago directory.
Please see documentation
to understand how to configure Galago to use them. Or ask the authors if you experience some issues.
We provide retrieval results of our models and baselines we used in the paper in runs directory.
Please see our presentation and paper if you want to understand how models works in more detail.
