Text processing systems and methods for checking in text processing systems whether units or chemical formulas are used correctly and consistently

摘要

A method for checking in a text processing system the correct and consistent use of units, comprising the steps of: storing a list of symbols or production rules that represent units; storing criteria, that state whether or not a symbol or a combination of symbols is interpreted as a unit; specifying allowable units and allowable notations thereof; searching the text for references to units, i.e. for strings that can be interpreted as a unit or part of a unit; checking whether the strings represent an allowable notation of an allowable unit; and generating an error signal, if not. If an unallowable unit is found, this unit and the associated number(s) may be transformed into an allowable unit. An analogous method is provided for checking the use of chemical formulae.
