space 704 and a selection of the search terms can be completed by a mouse or other selection mechanism the alternative way of interrogating the dictionary is to type the desired search term into search term selection space 705 for instance when a concept term search is selected and the word 34 computer 34 is to be the term searched the typing of the letter c into the space 705 brings up the same four selections in the dictionary search space as selecting the letter c from the string of letters 703 however as the typing continues the selection in the dictionary display space 704 diminishes first with the typing of the letter 34 o 34 cd drive vanishes from the list in dictionary space 704 and when 34 u 34 is typed 34 company 34 and 34 component 34 disappear leaving 34 computer 34 as the only selection in space 704 when the narrowing of the search field to the concept 34 computer 34 the property or attributes of the concept 34 computer 34 shown in fig6 appear in the identification space 706 if the search had been on properties rather than concepts a list of concept terms associated with the selection property term would appear in the identification space 706 with all.
