Alignment between two domain ontologies (Case of educational orientation in mathematics education)

Aligning ontologies is of particular importance in applications requiring the inclusion of semantic interoperability, it represents a great interest in the field of heterogeneous management knowledge. We present here the construction of an alignment between two domain ontologies (E-orientation[1], Extented Math Bridge [2]), whose interest is to guide the moroccan student in his learning curriculum. Thus, during the achievement of these activities, the student is automatically redirected to the appropriate exercises suitable to his profile (skills, preferences and motivation) [3]. Our goal is to find the possibility of alignment between the two models, and to determine their corresponding levels. For alignment methodes, we used: morphosyntactic matching technique [4], the resource WordNet [5] and the measuring structural similarity [6]. We also present a discussion of the results realized.
