Towards a Basic Principle for Ranking Effectiveness Prediction without Human Assessments: A Preliminary Study


We present in this paper a preliminary study about the Observational Information Linearity (OIL) assumption as a basic principle that explains the accuracy of pseudo relevance assessments in the IR literature. The proposed model predicts the effectiveness drop curve along positions in a single ranking, the relative performance of two rankings, and converges into the traditional pseudo assessment method when considering multiple rankings and statistical independence between them.
