Abstract: A computer implemented natural language processing method, the method including the steps of: analysing a sentence string within textual information to determine sub-components of the sentence string, assigning one or more unique tokens to each determined sub-component, determining a probability of use that a determined sub-component has one or more specific meanings, based on the determined probability of use, creating a valid set of unique tokens that are associated with the sentence string, and linking verb sub-components associated with one or more of the unique tokens in the valid set of unique tokens to a pre-defined limited sub-set of verbs to create an identification tuple that maps onto the sub-set of verbs.
