An experimental study on the iso-content-based angle similarity measure

摘要

An experimental study was conducted to examine and evaluate retrieval performance of the iso-content-based angle similarity measure presented in an earlier paper. Retrieval performance of the iso-content-based angle similarity measure within the angle, distance, conjunction, disjunction and ellipse retrieval models is compared with retrieval performance of the distance similarity measure and the angle similarity measure. The experimental results show the iso-content-based angle similarity measure achieves satisfactory performance.
