Theories distinguishing between -genuine differences- in language has been called for, and we propose that such differences can be observed through a notion of expressive mode. We outline this concept, propose how it could be operationalized and indicate a possible context for the development of a corresponding theory. Finally we consider a possible application in connection with evaluation of language revision. We illustrate this with a case, investigating possible revisions of the relational algebra in order to overcome weaknesses of the division operator in connection with universal queries.}, journal = {International Journal of Computer and Information Engineering}, volume = {2}, number = {11}, year = {2008}, pages = {3913 - 3918}, ee = {https://publications.waset.org/pdf/2020}, url = {https://publications.waset.org/vol/23}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 23, 2008}, }
