, but also semantic tags corresponding to recognized named entities or events can also be used for indexing text fragments and contribute to the relevance measure. Since extents are treated similarly to keywords in traditional models, our model will be integrated with any ranking and scalability techniques used by keyword-based models. We have implemented the ranking model in our retrieval engine, and had preliminary experiments to evaluate our model. Unfortunately, we used a rather small corpus for the experiments. This is mainly because there is no test collection of the structured query and tag-annotated text. Instead, we used the GENIA corpus (Ohta et al. , 2002) as structured texts, which was an XML document annotated with semantics tags in the filed of biomedical science. The experim...
