We present in this article, as a part of aspectual operation system, a generation system of iterative expressions using a set of operators called iterative operators. In order to execute the iterative operations efficiently, we have classified previously propositions denoting a single occurrence of a single event into three groupes. The definition of a single event is given recursively. The classification has been carried out especially in consideration of the duratire / non-durative character of the denoted events and also in consideration of existence / non-existence of a culmination point (or a boundary) in the events. . | ITERATIVE OPERATIONS Sae Yamada Notre Dame Seishin University Ifuku-ChÔ 2-16-9 700 Okayama Japan ABSTRACT We present in this article as a part of aspectual operation system a generation system of iterative expressions using a set of operators called iterative operators. In order to execute the iterative operations efficiently we have classified previously propositions denoting a single occurrence of a single event into three groupes. The definition of a single event is given recursively. The classification has been carried out especially in consideration of the dura-tive I non-durative character of the denoted events and also in consideration of existence I non-existence of a culmination point or a boundary in the events. The operations concerned with iteration have either the effect of giving a boundary to an event in the case of a non-bounded event or of extending an event through repetitions. The operators concerned are N F . direct iterative operators I G . boundary giving operators I . extending operator. There are direct and indirect operations the direct ones change a non-repetitious proposition into a repetitious one directly whereas the indirect ones change it indirectly. The indirect iteration is indicated with s. The scope of each operator is not uniquely definable though the mutual relation of the operators can be given more or less explicitly. 1 INTRODUCTION The system of the iterative operations which makes a part of aspectual operation system is based on the assumption that the general mechanism of repetition is language independent and can be reduced to a small number of operations though language expressions of repetition are different from language to language. It must be noticed that even in one language there are usually several means to express repetitious events. We know that il lui cognait la tẽte contre le mur and il lui a cogné deux OU trois fois la tête contre le mur the examples given by w. Pollak express the same event. We have also .
