Abstract Ontology matching is an important and prolific field of re-search, reflecting the growing interest of the community. This work makes a study over the different approaches and lines of research within the field of Ontology Matching, in order to help and guide new practitioners to approach the field and to determine possible lines of research. The study is based on a survey which has being conducted among the practitioners and which addresses different questions including the background, the future goals and the main achievements of the researcher. The purpose of such survey is to gain knowledge about the current state of art within the ontology matching field and on how such techniques are applied to real-life environments. From the results, the main conclusion achieved is that most researchers share the same concerns about the necessity of practical application of ontology matching techniques, due to the exist-ence of too many theoretical solutions but few applied ones.
