Coreference resolution plays a significant role in natural language processing systems. It is the method of figuring out all the noun phrases that refer back to the identical real world entity. Several researches have been done in noun phrase coreference resolution by using certain machine learning techniques. Our paper proposes a machine learning approach using support vector machines (SVM) towards coreference resolution at document level. In this research work, 17 well-defined syntactic and semantic features including the 13 baseline features with Semantic Role labeling (SRL) have been used. The use of SVM classifier leads to a better outcome when compared to other machine learning models. The system was evaluated using a machine learning technique and a non-machine learning technique. Experiments show that addition of SRL improves the performance of the system when compared to the Decision tree model and a non machine learning approach.
