Dear Steve Place,
thank you a lot for your very fast feedback
I am really beginner in working with Stardog and this is the reason why I am still confused.
I feel that solution will be very easy, but ...
I follow the pieces of information mentioned e. g. in tutorial - Entity Extraction and Linking (Entity Extraction and Linking | Stardog Documentation Latest) for finding out how it works.
In Preprocessing section, there is the information that some specific files (en-ner-person.bin, en-sent.bin, en-token.bin) have to be used for NER with person_movie.ttl "ontology". I think that the only one way how to add these files into the database (in the Stardog Cloud free version) is to visit the Properties section used for setting various properties of the database (named as Properties). There is e.g. empty field named as OpenNLP Models Path (docs.opennlp.models.path). Problem is that I do not know how to set the above mentioned files for this database. I feel that the whole line mentioned in tutorial (Preprocessing section) -> stardog-admin db create -o search.enabled=true docs.opennlp.models.path=/path/to/folder -n movies person_movie.ttl cannot be used directly in the OpenNLP Models Path (docs.opennlp.models.path).
If I follow the next instructions (Extracting entities section), additional file (text file named article.txt) should be used, but I do not know how to add this file into the database in the Stardog Cloud.
It seems to me that this tutorial and e. g. the next one (Unstructured Content | Stardog Documentation Latest) cannot be used for Stardog Cloud free version users.
Similarly, if I would like to use another tutorial for relations extraction (Extending BITES | Stardog Documentation Latest), I am also lost how to set all files (e. g. jar files) in Stardog Cloud.
This is the reason why I thought that e. g. NER or relations extraction are not available in the Stardog Cloud free version
Are there any tutorials which help me how to set up the database, i. e. how to set it to use additional files (*.txt, *.pdf, *.bin, *. jar, ...) in the Stardog Cloud? I think that they should be set up in the Properties section in the Cloud, but I do not know also which syntax should be used in their settings for various types of fields in the Properties section.
I am really apologize for my silly questions, but I think that Stardog has a great potential, especially in relation to the NLP, ML
Thank you very much for some advices.
