The paper is organized as follows. In section 2, we describe the overall architecture of our sys-tem. Section 3 discusses our improved frequency correlation-based feature, while Section 4 de-scribes in detail the document relationship heu-ristics used in our model. Section 5 rep[r]

Traditionally, information ex-traction and language understanding fields haveusually used a syntactic parser to encode globalinformation (e.g. parse tree path, governing cat-egory, or head word) over a local model.

experimental results show that our framework helps us to better understand and compare different FS methods. Furthermore, the novel method WFO generated from the framework, can perform robustly across different domains and feature numbers. In our study, we use four data sets to test our new m[r]

conducted by semiautomated, region centroid-based align-ment. The low magnitudes of these similarity values (ap-proximately in the interval [0.325,0.365]) proved that theintensity-based automatic alignment would not be robustand would very frequently fail. As a consequence, we did nota[r]
