Hi, you can also import your dependencies directly if you have a maven project. On Maven, add dependencies, and then type jena. That brings you all dependencies related to jena. (eclipse). Luis Ramos El mar, 21 jun 2022 a las 8:19, Dương Hồ () escribió: > Hi All. > I want test use Jena

Re: Apache Jena rules to find the minimum in a list of data property values

Hi dear, The issue here is the monotonic level of owl, with sparql functions you can get this information, but with owl based rules, or inference not (in a set larger than 2). The point is that to get that the reasoner (or function) should create a list, order it and extract the first or last

Hi, If I properly understand your notation, you are try to obtain an instance as an inferred class. In this case is CatPerson, a person who only has a pet of kind cat. And, as I see you defined person_1, and you say he has a cat, then you expect the system to infer he is a cat person, and
