Abstract

This paper shows how the s-term ranking model [1] is extended and combined with index structures and algorithms for structured document retrieval to enhance both the effectiveness of the model and the retrieval efficiency. We explain in detail how previous work on ranked and exact retrieval can be integrated and optimized, and which adaptions are necessary. Our approach is evaluated experimentally at the INEX workshop 2004 [2]. The results are encouraging and give rise to a number of future enhancements.
