Our goal is to generate OWL files from complex tables with material data，using TMEDSM as a middle model.Tab.2shows the efficiency on generating ontology with 1 000 instances.We previously proposed an algorithm for transforming source data in material experiment tables to databases[4].At the size of 1 000data sets，we compare ontology algorithms with database executions，as shown in Tab.2.This approach is approximately 5times more efficient than database executions，implying efficiency to generate ontologies from tables and trees directly instead of from databases for secondary conversion.
