چکیده
Ontology mapping is the task of finding semantic relationships between entities (i.e. concept, attribute and relation) of two ontologies. In the existing literatures, many (semi-)automatic approaches have found considerable interest by combining several mapping strategies (namely multi-strategy mapping). However, experiments show that multi-strategy based mapping does not always outperform its single-strategy counterpart. We here mainly consider the following questions: For a new, unseen mapping task, should one use a multi-strategy or a single-strategy? And if the task is suitable for multi-strategy, then which strategies should be selected in the combined scenario? This paper proposes an approach of multiple strategies detection for ontology mapping. The results obtained so far show that multi-strategy detection improves both on precision and recall significantly.

We present an approach based on multiple representations and multiple queries to tackle the problem of invariance in the framework of content-based image retrieval. We consider the case of textures. This approach, rather than to consider invariance at the representation level, considers it at the query level. We use two models to represent the visual content of textures, namely the autoregressi...

AIM To study the dose-response of stage I non-small-cell lung cancer (NSCLC) in terms of long-term local tumor control (LC) after conventional and hypofractionated photon radiotherapy, modeled with the linear-quadratic (LQ) and linear-quadratic-linear (LQ-L) approaches and to estimate the clinical α/β ratio within the LQ frame. MATERIAL AND METHODS We identified studies of curative radiothera...
