Citation Matching is the problem of identifying if two citations are essentially the same despite some differences in the order of the meta-information entities(title,authors,venue,etc) or the entities themselves (e.g. Mooney, RJ vs Mooney, Raymond etc.)
One of the paper attempting this problem using Markov Logic Networks is Joint Inference in Information Extraction.
