                    inputPattern="[ regular expression pattern used to extract terms from text ]"
                    startPattern="[ pattern that marks the beginning of the extracted term ]"
                    includeStartPattern="[ true if startPattern should be included, false(default) if it is a prefix marker ]"
                    endPattern="[ pattern that marks the end of the extracted term ]"
                    includeEndPattern="[ true if endPattern is part of extracted term, false(default) if it is a postfix marker ]" />
