... background in Markov logic. We then describe our Markov Logic Net- work (MLN) for grammar error simulation. Fi- nally, we present our experiments and results. 2 Overall process of grammar error si- mulation ... statistical grammar error simulation that can incorporate this type of knowledge about language learners’ error characteristics and shows that it does in- deed...

... Jurafsky. Instead of combining the output of a set of local classifiers using ILP, we approach the problem of joint temporal relation identification using Markov Logic (Richardson and Domingos, 2006). In this 405 framework ... of these methods are often already provided in existing Markov Logic inter- preters such as Alchemy 7 and Markov thebeast. 8 4 Proposed Markov Logic Network A...
