... put into feature engineering. 5 Conclusion To avoid binary distinctions used in previous ap- proaches to automatic treebank conversion, we pro- posed in this paper a feature- based approach. Exper- iments ... a heterogeneous parser, we use feature- based parsing algorithms in order to easily incorporate features that encode source-side bracketing structures. Theoretically, any feature- based approaches ... they are referred to as target side features. This group of features are completely identical to those used in Sagae and Lavie (200 6a) . In addition, we have features extracted jointly from target-style...

Feature- based approaches transform the context of two entities into a liner vector of carefully selected linguistic features, ... Related Work Many approaches have been proposed in the literature of relation extraction. Among them, feature- based and kernel -based approaches are most popular. Kernel -based approaches exploit ... paper, we study a feature- based approach that basically integrates entity related information with context information. 3.1 Classification Features The classification is based on the following...
