Literature search show that information retrieval (IR) systems on Arabic are little compared with English language. Additionally, IR systems face many problems when used with Arabic language, including, complexity and ambiguity. The performance and effectiveness of interactive query expansion (IQE) and automatic query expansion (AQE) represent a key towards improved IR systems. The performance and effectiveness of IQE compared with AQE have been examined via a series of search experiments on Arabic content. Compared with no query expansion, the experimental results showed that AQE provides enhanced performance and effectiveness, with 54% query improvement and average precision of 42.1. However, results revealed that IQE provides high performance and effectiveness compared with AQE, with 84% query improvement and average precision of 43.4.

Keywords: Arabic language, Arabic content, evaluation of information retrieval, query expansion, IQE, AQE.
