Using Protege and SWRL tab, I have the ontology mentioned hereinafter. It is composed of the Class Test and the class Shadow, where Test has three individuals t1, t2, t3. I was trying to define an SWRL rule that creates an individual of Shadow class for each existing individual of Test, the rule is
Test(?x) ^ swrlx:makeOWLThing(?new, ?x) -> Shadow(?new)
QUESTIONS:
1. Only one individual of Shadow, named fred is created, instead of three (corresponding to t1, t2, t3).
2. How to control the naming of the resulting individual which is always named fred?
Here is my ontology:

I try to get all 'subclass-of' axioms of an ontology. I tried by using the following statement.
MyOntology.getAxioms(AxiomType.SUBCLASS_OF));
Effectively, it returns the ontology 'subclass-of' axioms, except for the first 'subclass-of' axiom which links OWL:Thing with my first ontology class.
I cannot understand why this link isn't taken into account in that case ?
Please, is there any way to get all 'subclass-of' axioms including those linking OWL:Thing with other classes ?
Dear researchers,
There are some Web sources which are accessed just by Web robots and human users are unaware of them. 'robots.txt' file is a good example of such sources which is practically used as an indicator for detecting Web robots.
I would be appreciative if you let me know what are other Web sources (like files) which are just accessed by Web robots and used as an indicator for these crawlers.
I am looking for an automatic semantic annotation tool that be able to recognize mentions to instances of concepts or concepts within WordNet, it means an automatic semantic annotator which uses WordNet as base ontology.
Thank you for your time.

I am trying to find the semantic similarity between two documents....Which method/metric scales the best at present? Any related literature regarding this? Most of the metrics I found works on sentence level...any insight into document level semantic similarity measurement?
iIs there any methodology for building probabilistic ontologies ?
Hi i am trying to prepare program for ppswr sampling with distinct unit using cumulative total method for my P.hd work .pls help me to write this type of program.
How could we define and perform Sentiment Analysis based on Semantic Web technologies ? What about ontologies as a mean to express semantics ? Are they of use in the Sentiment Analysis context ?
I'm working in semantic web technologies in particular those of semantic web services: OWL-S , WSMO and SAWSDL.
I remark that SAWSDL becomes a W3C recommendation but OWL-S not yet. Knowing that, the OWL-S components have more semantic expressivity specifically the behavioral aspect of services. I'm asking why OWL-S still not a recommendation. Moreover, I remark that researches in the field of semantic web services have been almost abandoned?
I'm working on Semantic web technologies; I have developed a semantic meta-model for semantic description of e-government data and services. Because of the important volume of published data in this area, I aim to use the BigData technologies beside semantic technologies. I want to know if there are works in this context of applying semantic technologies for BigData .
I'm working with Linked Data (DBpedia in my case) and want to know whether this is the best one among others such as edge counting, information content or maybe hybrid measures.
I developed Ontology, goal and web service in wsmo framework and discover but now I want to execute this service via wsmx. How can we run it.
I am searching for some algorithm to find in-direct relations among RDF concepts e.g. relation between a 'Book' and publication date. There is no direct property that can relate these two and we have a multi-link path to find this relation i.e. 'Book' got a publication event, A publication even got property event time, Event time got a Calendar year that has a label. In short we will come up with following statements (for SPARQL)
{?book a bibo:Book}
{?event a blt:PublicationEvent}
{?book blt:publication ?event}
{?event event:time ?time}
{?time rdfs:label ?year}
Is there any implementation already available (like Jena API) that helps to find in-direct paths for connecting concepts?
Is it possible to make a system learn about semantics of words, phrases or sentences? If possible, how might this be achieved?
Does anyone know about a tool that can do A-box level comparison of two versions of the ontology ?
I would like to compare the A-box level similarities and differences between two versions of the domain ontology.
SUMO OWL=(T-Box)+(A-Box)
but, i want only T-box
I am doing a quantitative analysis, so I need a tool that can gather all data, specially text, from many websites. I found Fminer, it's very useful but not free. Can you please suggest to me any tool you know similar to Fminer?
What is the functionality of each layer of layer cake . I want to get the answer of this question with an example where starting from unicode and uri (bottom most layer) to trust (top most layer), all level is described for a sentence. thanks for your support....
Hello everybody, can you please mention some key semantic technologies (specific examples please) deployed in Digital Preservation? I am currently working on a DP project (called PERICLES - see link) and one of the main tasks is to deploy ontology-based representations for domain modeling. What other applications have you come across? Thanks a lot in advance!
As RDF and Ontology belong to two separate layers in the Semantic Web Layer cake so I want to understand the difference between these two layers? Most of the data on the internet said these two are same. Please help me to understand the difference?
I have found the one available by Uni of Manchester (http://www.w3.org/2001/sw/wiki/OntologyBrowser), but I was wondering if there are any other tools out there. Google does not seem to find any alternatives, though.
Note that I am NOT looking for an ontology editor but simply for a browser.
I have been looking for some article or presentation on the application of semantic webs and ontologies in education in China. I have not found anything until now. Does anybody know any sources related to this theme?
We are looking for a method to transform ADL files to XML format to use data mining in medical records management platforms.
My current knowledge is limited to the REA ontology, the e3-value ontology, DEMO, BMO and Enterprise ontology. I would like to discover other enterprise ontologies and connect with researcher that develop/study them.
I am currently doing research into the semantic web and ontologies, and how they can support scientific research and discovery. I am interested in taxonomies and ontologies which are used to describe scientific research. Detailed ontologies exist for many domains of scientific research, but I am looking for ontologies which describe the overall structure of scientific research disciplines. For example the “topic” structure of ResearchGate itself could be seen as a classification of research topics, although it is not a full ontology. Do any such ontologies exist?
