1. An assignment device for obtaining meaning from an input text to identify an appropriate action to be taken based on the meaning, the assignment device comprising: at least one computer programmed to implement: an assignment component configured to access a word-class table associating each of a set of words with one of a plurality of word-classes to which the respective word is a member, each of the plurality of word-classes characterizing a categorical commonality of all member words related to the definitional meaning of the member words, the assignment component determining whether each word in the input text is included in the word-class table and assigning word-class information to each word in the input text that is included in the word-class table that indicates to which word-class the corresponding word is a member, and providing word-class sequence information containing the assigned word-class information in the sequence in which the associated words appear in the input text; a linkage component configured to access a linkage table that associates a plurality of different combinations of word-class information with respective linkage information, the linkage component configured to detect if any of the plurality of combinations of word-class information are present in the word-class sequence information, and provide the associated linkage information for each detected combination; and an action component to receive the provided linkage information and configured to access an action table that associates linkage information and/or combinations of linkage information with a corresponding action, the action component configured to access the action table to detect if any action is associated with the linkage information received from the linkage component, and to activate each action detected as being associated with the linkage information.

An assignment device as claimed in claim 1 , wherein the word-class table includes a medicament class and the linkage table includes at least one combination of the medicament class and another of the plurality of word-classes, and wherein the action table includes at least one action including providing an alert when the input text includes a member of the medicament class and a member of the another of the plurality of word-classes.
