  • Probabilistic Models

    In this repository you find the implementation of the probabilistic models analysed in the paper: ``A systematic approach to normalization in probabilistic models``.

  • Pool Bias Estimators

    In this repository you find the implementation of the pool bias estimators analysed in the papers, ``Splitting Water: Precision and Anti-Precision to Reduce Pool Bias`` and ``The Curious Incidence of Bias Corrections in the Pool``.

    With Pool bias in Information Retrieval (IR) is meant the bias of a test collection against new systems that appears as side-effect of the use of the pooling technique. In this repository we find the implementation of the pool bias estimators analyzed in the SIGIR-2015 paper: “Splitting Water: Precision and Anti-Precision to Reduce Pool Bias” and in the ECIR-2016 paper: “The Curious Incidence of Bias Corrections in the Pool”.

    The application has two use cases, analysis of the test collection and run bias correction.

    The available IR measures are: P@10, P@15, P@20, P@30 and P@100.
