The ontology was created using Protege and I converted it to ACE with the help of the "Ace View" plugin. Using the resulted ACE statements I would like to provide the user with the possibility of issuing simple ACE language questions. I tried to test using the RACE Web Service, but I keep getting an error: "time_limit_exceeded. Web service call failed". I only used 10 Axioms, which is a small part of the total number I wan't to use for the final version.<br> I also tried running the "Pellet" reasoner on OWL data obtained by first transforming to ACE, then adding the ACE query and then transforming again to OWL XML with the help of APE, but I get an error because it apparently can not transform ACE questions using "What" to OWL.<br> This project is part of my Bachelor degree assignment so I need to know as soon as possible if this approach can be used. Is there any way of running RACE locally? If not, how could I get around this problem?<br> </blockquote> <br></div></div> Calin<br> <br> As Kaarel already wrote it is difficult to answer without further details. Please send me your axioms and your query. Be aware that I am in vacation in Sicily and not permanently connected to the internet.<br> <br> I just ran RACE successfully with 13 axioms and got an answer in .5 seconds.<br> <br> The error message that you got is not generated by RACE itself, but by its web-service. Try to submit your ACE axioms and your "what" questions directly in the RACE web-client. Possibly you need to prefix unknown words by their word-class. For details how to prefix see the help text of the APE web-client.<br> <br> Currently, RACE can only be used via its web-client. A public release is planned for later this year.<br> <br> Best regards.<br><font color="#888888"> <br> --- nef<br> <br> <br> </font></blockquote></div><br></div> </div></div></blockquote></div><br></div></div>
