... present paper we use a machine- learning ap- proach in order to add Cast3LB function tags to nodes of basic constituent trees output by a prob- abilistic parser trained on Cast3LB. To our knowl- edge, ... attributed to two main factors. Firstly, the mapping from Cast3LB tags to LFG grammat- ical functions is not one -to- one. For example three Cast3LB tags (CC, MOD and ET) are al...

... the use of learning for NERC. In- stead of using ML to construct a NERC system that will be used autonomously, the system con- structed by ML, according to our approach is used to monitor the performance ... Us- ing Machine Learning Machine learning has been used successfully to control a rule-based system that performs a dif- ferent task, namely document filtering (Wolinski...

... (84.36% in test). There- fore, we decided to adopt this as a basis in order to get an automatic clause splitting tool for Basque. But as it is known, machine learning techniques cannot be applied ... for each token, we stored whether it was followed by a comma or not. That is, for each word (token), it was stored whether a comma was placed next to it or not. Therefore, each to...

To further reduce the search space for the MDP, our tool allows the user to specify a threshold to com- bine states that occur ... of how best to influence student state. Our goal in this study is to automatically learn from this corpus which state-action patterns evoke the highest learning gain. 4 Infr...
