16. A computer program product comprising one or more computer-readable storage media, and program instructions stored on at least one of the one or more storage media, the stored program instructions comprising: program instructions to determine that tokens have been incorrectly separated due to an incorrect Natural Language Processing (NLP) operation on a corpus; and program instructions to recombine, as a part of correcting the incorrect NLP operation, the incorrectly separated tokens, the recombining comprising: program instructions to determine whether a token from an ordered set of tokens is present in a dictionary, the dictionary being related to the corpus from which the ordered set of tokens is extracted; program instructions to determine whether a compounding threshold has been reached, wherein the compounding threshold limits a number of tokens that can be agglutinated to form a compound token; program instructions to agglutinate using a processor and a memory, responsive to the token not being present in the dictionary, and responsive to the compounding threshold not having been reached, the token with a next adjacent token in the ordered set of tokens to form the compound token; program instructions to determine whether the compound token is present in the dictionary; program instructions to assign a weight to the compound token responsive to the compound token being present in the dictionary; program instructions to compute a confidence rating of the compound token, the confidence rating being a function of the weight; and program instructions to use the compound token and the confidence rating in performing an NLP operation on the corpus.
