Secondly, we use GenPropBank to train a biomedical SRL system, which uses maximum entropy as a classifier. Our experimental results show that a newswire SRL system that achieves an F1 of 85.56 % in the newswire domain can only maintain an F1 of 65.43 % when ported to the biomedical domain...
Maximum Entropy classifier [190] is a probabilistic exponential classifier which can be used to solve text classification problems such as language detection, sentiment analysis, named entity recognition and many more. The MaxEnt works on the principle of Maximum Entropy which states that from all the...

Maximum-entropy Markov model author: Emily Hua Goal: implement MEMM to predict BOI tags Information about the program: some non-ASCII chars(mainly punctuations) may break the stemmer: replace them with ASCII punc. It has two programs: MEMM_1.py and MEMM_2.py; 1 python pickle file: my_...
1.The use of state-observation transition functions rather than the separate transition and observation functions in HMMs allows us to model transitions in terms of multiple, nonindependent features of observations, which we believe to be the most valuable contribution of the present work. ...

Semantic role labeling (SRL) is a natural language processing technique that identifies the semantic roles of these words or phrases in sentences and expresses them as predicate-argument structures. We construct a biomedical SRL system called BIOSMILE that uses a maximum entropy (ME) machine-...
