In this paper, we present four clustering algorithms for noun phrase coreference resolution. We developed two novel algorithms for this task, a fuzzy algorithm and its hard variant and evaluated their performance on two different sets of texts in comparison with an existing fuzzy and a hard clustering algorithm that are described in the literature. Our algorithms perform slightly better and do not rely on a predefined threshold distance value for cluster membership. In addition, our fuzzy clustering algorithm seems to perform better than a hard clustering on a pronoun resolution task.
