I  wonder why this gives me error when I use it as string

I sit Domain of FavoriteLeague as Team and Range as Literal, but still it
does not work. Error is semicolon expected,

Re: Property stored in Annotaion Section

Hi Lorenz, I have provided the whole rule in earlier messages. The error
comes when I use FACup as string. When I use it as resource, it gives the
result but in Annotation area.

// when use as string

-> (?x http://www.semanticweb.org/soccer#FavotiteLeague  "FACup" ) //it
gives error ; expected


 //when use as resource

-> (?x http://www.semanticweb.org/soccer#FavotiteLeague

//Annotation problem here

Re: Property stored in Annotaion Section

[neha gupta]

Sorry I did mistake in previous email, I used string like this

 ->  (?x  http://www.semanticweb.org/soccer#FavioriteLeague

"FACup" and it gives error.

The string value in rule I found on web from link below: he used rules like

[rule: (?S rdf:type data:serveur), (?S data:identifiant-reseau
"POLO")-> (?S data:newproperty "TEST")]

Yes Andy, I tried this and it flushed an error message. Thats why I asked
it if it is possible and if yes, in what way we can use the String in rule.

Re: Property stored in Annotaion Section

[neha gupta]

Hello Lorenz, I am sorry.

Can we use FACup as string rather than a resource. I mean it is also
possible, if allowed by rules, that we use something like this

(?x http://www.w3.org/1999/02/22-rdf-syntax-ns#type http://
www.semanticweb.org/soccer#Team) "

 + "( ?x http://www.semanticweb.org/soccer#FACupGoals  ?goals )" +

"greaterThan(?goals,30)
 + " ->  (?x  http://www.semanticweb.org/soccer#FavioriteLeague
http://www.semanticweb.org/soccer#
<http://www.semanticweb.org/soccer#FACup>"FACup"
)]";

FACup, ChampLeague etc are just some plain strings.

Re: Property stored in Annotaion Section

[neha gupta]

I want to ask Lorenz, about the Then part of the rule:

THEN-> team FavoriteLeague is FACup

FACup is the resource in my owl (just followed Create Instance tab in
Protege and Protege has give it the default URI like other resources in the
file).

Before we execute the rule, is it must that we should declare it in Java
code like we do in Jena class before using it in Rules like
OntClass team = model.getOntClass(ns + "Team")

Because I am sure the problem lies in the resource FACup (or its URI).

Regards

In simple words, do we need:

inf.getResource(URI of FACup)  ?

I did not use it so far.

Re: Property stored in Annotaion Section

[neha gupta]

I am sorry for any inconvenience I have created. I really dont know how to
create minimal code snippet or uses Github.

Coming to the problem, what I noticed is the problem is in the object i-e
FACup here.
team1  FavoriteLeague  FACup

Because I made changes and coming to the down, used different properties
(in place of  FavoriteLeague), and made the rule simple to:
If x is a Team, then x FavoriteLeague is FACup ,
If x is a Team, then x Wins is FACup etc just for simplicity.

In a nutshell, changed everything except object of rule FACup and it
appears in Annotation area so the problem for sure is in the URI of FACup.

Now about resources FACup, PremierLeague, ChampionsLeague, these are not
associated with anything in the ontology (neither Types of anything, nor
data/object assertions), rather I just created it in Protege with URI like
other resources.
URI of Team Class: http://www.semanticweb.org/soccer#Team
URI of FavoriteCategory : http://www.semanticweb.org/soccer#FavoriteCategory
and URI of FACup: http://www.semanticweb.org/soccer#FACup

So I dont know if it is mandatory to get the value of resource
http://www.semanticweb.org/soccer#FACup first before the rules executes
because simple putting it in the rules not working for me.

Sorry once again.

Hi Lorenz, the ns is wrong, how?

String ns="http://www.semanticweb.org/soccer#

Rule:

Re: Property stored in Annotaion Section

[neha gupta]

Hello Lorenz, I am sure I have used the FavoriteLeague as Data Property in
Protege and it has the same URI as other data properties and other
resources in the ontology ie  http://www.semanticweb.org/soccer#
<http://www.semanticweb.org/soccer#FACupGoals>FavoriteLeague.

I have changed the spelling of FavoriteLeague. to FavoLeague, favLeague,
but every time the same disappointing result.
My namespace is also same in whole program:

*String ns="http://www.semanticweb.org/soccer
<http://www.semanticweb.org/soccer#FACupGoals>#";*
favleague is declared as:

 *OntProperty favleague=model.getOntProperty(ns+ "FavoriteLeague");*
//All my data properties are declared like this and it works.  For ex: Goal
property
OntProperty goals=model.getOntProperty(ns+ "Goals");

Re: Property stored in Annotaion Section

[neha gupta]

I used like this

 *OntProperty favleague=model.getOntProperty(ns+ "FavioriteLeague");*
Then I wrote this rule:

(?x http://www.w3.org/1999/02/22-rdf-syntax-ns#type
http://www.semanticweb.org/soccer#Team) "

 + "( ?x http://www.semanticweb.org/soccer#FACupGoals  ?goals )" +

"greaterThan(?goals,30)
 + " ->  (?x  http://www.semanticweb.org/soccer#FavioriteLeague
http://www.semanticweb.org/soccer#FACup  )]";
//FACupe is resource in the ontology:

Then
  *inf.listStatements(null,favcat,(RDFNode)null);*


I think the problem is not in typo because I run similar rule for another
data property FavioriteStadium and it also saves in Annotation area.

Re: Property stored in Annotaion Section

Even this not works

 inf.listStatements(null,favleague,(RDFNode)null);

Gives the result but in Annotation area of Protege

Re: Property stored in Annotaion Section

[neha gupta]

I used FavioriteLeague, though I later knew the spelling is incorrect.

What you suggest Lorenz now what should I do to handle this problem because
it has stopped me to move forward in my project.

Thank you

Re: Property stored in Annotaion Section

[neha gupta]

I am sorry, in theory I know most of things, but when it come to coding, I
make mistakes.

I know Literal can be any string or integer value and resources are what we
used in our ontology (some things).

Object of property FavioriteLeague is a resource : FACup, in this case,
whose URI is



http://www.semanticweb.org/soccer#
<http://www.semanticweb.org/soccer#FavioriteLeague>FACup or
http://www.semanticweb.org/soccer#ChampLeague etc

Re: Property stored in Annotaion Section

[neha gupta]

 How should I share the ontology, the attachment is not allowed here?

 I used this to execute the rule

 for (Iterator i = inf.listResourcesWithProperty(RDF.type,
favioriteleague); i.hasNext();)
 {
 inf.listStatements(null,RDF.type, "FavioriteLeague");

}

I think the problem is here in the code.

Re: Property stored in Annotaion Section

[neha gupta]

Lorenz, what actually I did is created a data property in Protege :
"FavioriteLeague".

Then I wrote this rule:

(?x http://www.w3.org/1999/02/22-rdf-syntax-ns#type
http://www.semanticweb.org/soccer#Team) "

 + "( ?x http://www.semanticweb.org/soccer#FACupGoals  ?goals )" +

"greaterThan(?goals,30)

Re: Property stored in Annotaion Section

[neha gupta]

The data is stored in RDF/XML

 model.write(writer, "RDF/XML");

All other properties works fine and stored as data property but just this
one property is stored in Annotation area.
Some weeks ago, I face the same problem but then it was fixed by random
changes to code. I dont know in which situation this problem comes?
I did not show the code because one type of code depends on other and you
will not be able to understand it easily.

Property stored in Annotaion Section

[neha gupta]

Hi
I have a rule like this

If a team Goal>30 in a League (PremLeague, ChampLeague etc) then it is the
team FavioriteLeague.

FavioriteLeague is a data property to which teams will be assigned through
rules. But the problem here in my case is when I run the program, the
FavioriteLeague property is saved in the "Annotations" section, near
rdfs:comment and label. Also I see ManchesterCity FavioriteCategory
PremLeague in Annotation section.

Why this stored there and not as Data property of the team.?

Thank you

Add(Sum) operation about individuals not working

[neha gupta]

Hello

I have team ontology in which we need to store information about teams like
team wins, goals etc. I need to calculate the team goals in three
categories: PremiurLeague, ChampionsLeague and FA cup.(From combo box each
category should be selected)

 if (Category=="PremiurLeague"){
//get goals
int premGoals=somevalue;
team1.setPropertyValue(goals, literalvalue);

}
if (Category=="ChampLeague"){
//get goals
int champGoals=somevalue;
team1.setPropertyValue(goals, literalvalue);
}
if (Category=="FACup"){
//get goals
int FAGoals=somevalue;
team1.setPropertyValue(goals, literalvalue);
}

int total=premGoals+champGoals+FAGoals;

But it does not give me the total goals, though it gives the individual
league goals.

Note: We enter the information about teams in one or two league at one time
and of third league some other time. So its not necessary to enter
information about all three leagues at one day. *Is it the main issue
because we use setpropertyvalue() method which replaces previous values*.

Thanks and happy New Year

Re: listresourceswithproperty()

[neha gupta]

What is the difference between then in
"model.listresourceswithproperty(RDF:type,
Student )"  and

 model.listStatements(null,RDF.type, "Student"); //Student is class in our
ontology

If we want to just retrieve the list of Students (rdf:type Student), which
of the above statement is correct? Or we should write both these
statements.

[neha gupta]

Hi Soroka, it will lists both the subjects and objects of the Property p,
right?

listresourceswithproperty()

[neha gupta]

Hello, I want to ask what is the function of this method:
 listresourceswithproperty()

And is it the same as when we query SPARQL like:

Select ?x
where { ?x rdf:type ?someclass }

A simple example is highly appreciated as I did not find any solid examples
on web about it.

Thank you

Correct syntax of rules

[neha gupta]

(1) greaterThan(?score1,?score2)^(?score1, ?score3)

 (2) greaterThan(?score1,?score2)^ greaterThan(?score1, ?score3)

 In Jena rules, the ist statement is correct or the second?

"Resource as Object" in Rules

[neha gupta]

I have a rule like if a team "wins" in Etihad stadium is greater than some
threshold, Then
?team lg:FavioriteStadium lg:Etihad.

lg:Etihad is an instance/resource in my owl file, so can I use this as
object in Then part of the rule? Some one told me you can only use a Class
as object in Then part and that lg:Etihad must me a class, not resource.

Re: Infer data property values

[neha gupta]

Hello Lorenz Thanks again. My variable is like

 OntClass favVariable = model.getOntClass(ns + "FavioriteStadium");

//then Jena rule

Since I will login to the system as team1, all information saved will be
for team1. Similarly for other teams.

In my owl file, I have instances (Resources) like "Manchester, Arsenal,
Chelsea etc" for objects of my triples like:
team1  FavStadium  Manchester
team2  FavStadium  Chelsea etc

If I just write the inference model inf to the file like inf.write(), where
it will be saved? As data property?

I have saved all other properties (not in inference model, but traditional
model) like:

team1.setPropertyValue(). I dont know how to do this in the inf model case.

Infer data property values

[neha gupta]

Hello

I have a data property in my owl file: "FavoriteStadium" for a team.
Triples will be like team1  FavoriteStadium   ?stadium.

I will infer the instances using a Jena rule like if a team win % is more
in a particular stadium, it will be her favorite stadium.
I have two questions here:

1) How can I get the instances like  team1  FavoriteStadium   ?stadium.
Is it the right approach? * inf.listResourcesWithProperty(FavoriteStadium,
favVariable);*

2) *How can I then save it as data property in a file for team1*? I have
other properties like this:
team1  Wins  10
team1  Goals  150
team1  income  70%

Similarly I want to add it like
team1  FavoriteStadium  ?SomeStadium

Thanks

Re: property values

[neha gupta]

Is it a good idea to use team1.addLiteral() before team1.getPropertyValue()
just to assign some value to the property?
And then we can write team1.setPropertyValue() to assign the final value?

I want to ask why data property value "win" does not have default zero

property values

[neha gupta]

Hi
I want to get the property value and then add add/sum 2 for each team with
it.
team1(win value +2) // value is 2 here
team1(win value +2) // value is 4 here

team.getPropertyValue(Win);
//then next operation to get value and sum 2

But the issue is I get error as I have not set the value first. But if I
set value before get the value, the property "win" always show that value
and not after calculated value.
Is there any way for this issue?

resultset as string

[neha gupta]

I have a query which has output of one single string line "My name is ---,
living in city -, located in country .

After query string , I have executed the query

 Query query = QueryFactory.create(queryString);
QueryExecution qexec = QueryExecutionFactory.create(query, model) ;
ResultSet rs = qexec.execSelect() ;
I want this string to be displayed as string:
JOptionPane.showMessageDialog(null, string);

But I dont think I need while(rs.hasNext()) and convert it to string
because resultset only contain one string output at one time.
How can I display the resultset as string?

Two Models handling

[neha gupta]

I have ontology in which I want to add Team wins and goals. In this
ontology I uses only the current wins using:
team.setPropertyValue() as it over write old data.

I also need to keep track of previous team wins, goals etc so I want to
store it in another owl file and will use
team.addLiteral(). I will use another model for that i-e model2

But I dont know how to write that specific values to second ontology. I
mean I will have team.setPropertyValue() in my main model and will be
stored in my main owl file. But how can I store team.addLiteral() in my
second owl file using model2 ?

my main model to write in file is at the end of code is :
 infmodel.write(writer, "RDF/XML"); //Because I used rules

Re: Statistic of Data in owl file

[neha gupta]

Yes students here are working on projects but we are working independently.

Will it be useful if we use another owl file to store information,  apart
from our main owl file. And use team1.addLiteral() for Number of goals,
wins etc so that data might not be over written.
And in our main owl file, just use recent information using
team1.setPropertyValue().

Re: Statistic of Data in owl file

[neha gupta]

David, what if we write something like this

team1.setPropertyValue(Goals, literalvalue)

If we enter Goals next time, the previous value will be vanish, right?

Re: Statistic of Data in owl file

[neha gupta]

I want just to know is there any approach in which we can keep track of
data previously entered.
I am very sorry but I have not tried any thing related to it as I am
completely blind it? I searched the web from last three-four days but could
not found hints. That is why I asked here in the experts forum.

Statistic of Data in owl file

[neha gupta]

Good evening,
I have some team information in my ontology i-e team1 wins, goals, Euro
goals, Worldcup goals.

 team1 information will be stored like this in owl file. After one month,
again team1 information will be entered, which of course, will over write
the previous one.

Can I maintain the information previously entered *(store previous
information in some pdf, word format or any other method*) because after
one year I have to maintain some statistics of team1 and their performance
in the year?

Re: sum property values

[neha gupta]

yes because what I studied about SUM is it sum the values of single
variable.

SELECT (?worldcupgoals + ?eurogoals+ ?othergoals))
where { ?team rdf:type ont:Team . ?team ont:WorldCup_Goals ?worldcupgoals;
ont:EuroCup_Goals ?eurogoals ; ont:Other_Goals ?othergoals}

Will it works like:

I am sorry but need some details? I really have no idea how to sum multiple
values (data properties) using SPARQL, despite searched the web.

sum property values

[neha gupta]

team1  WorldCup_Goals  20
team1  EuroCup_Goals   25
team1  Other_Goals50

WorldCup_Goals,  EuroCup_Goals and Other_Goals are my properties.

How to calculate total goals of team1 using SPARQL?

Is it the right way to get int value from a property?

 RDFNode intValue =team1.getPropertyValue(wins);

Re: Fetch value from data property

[neha gupta]

"You have to get the "wins" value for "team1" first"
This is the basic problem I do not know how to get the int value from
"wins"?

"you first have to get the "team1" individual/resource."
I have individual like this:
 Individual team1 = team.createIndividual(ns + name); //name java variable.

Re: Fetch value from data property

[neha gupta]

I am sorry Lorenz sir,
Basically what I want to sum a team wins. When value is entered in text
field, it is saved as data property "Wins" value in the file i-e team1 Wins
3. Since this value 3 is stored in owl file, when another entry is made for
Wins property, say 2, I want to sum this new value with the previous value
of Wins property so that it does not stored in the file as:
team1 wins 2
team1 wins 3

*but rather it is stored as:*
*team1 wins 5*

// variable is java variable having integer value i-e 2
*Literal wins=model.createTypedLiteral(variable);*
*int win_value=wins.getInt();*

*I just want to sum win_value (i-e  2)  with the value in data property
"Wins"*

OntProperty winsProperty = model.getOntProperty(ns+ "Wins");

So without SPARQL, can we get integer value of data property Wins so that
we can do

 int total_wins= win_value+ (The value from data property Wins).

Sorry again for these types of questions, but I am learning Jena course my
own and I have not studied it in my Bachelor degree (But have to use it in
my BS project)

Fetch value from data property

[neha gupta]

Is this a proper way to fetch the int value from data property?

OntProperty value=model.getOntProperty(ns+ "Wins");

 Literal myliteral = model.createTypedLiteral(value);

   int sum=myliteral.getInt();
   sum=sum+1;

Actually I have the same query like Tina, but can you explain it in term of
a Student ontology because I understand the Student ontology more.

Like Student hasCourse ?course.
Teacher teaches ?course

Re: Construct query

[neha gupta]

Paul, thank you.

If I have Student/University ontology and the ontology does not have
"hasResearch" property can we create like this:

CONSTRUCT {?s ex:hasResearch ?research}
WHERE {?s rdf:type ex:Student;ex:hasResearch  "C-SPARQL"}

to create the property and assign instance to it?

Re: New entered value does not sum with previous value in owl file

[neha gupta]

Hello Lorenz, I have assigned the value to team1 but mistakenly typed only
team.
The Chris Dollin comment about "*setPropertyValue is /documented/ as
deleting any previous value **for that property" *
*makes sense but if I write *
team1.addLiteral(goals, p), in place of team1.setPropertyValue(goals, p)

then it saves new data and the previously saved data is also there.

Actually their are many call from other classes thats why it is useless to
copy all the code and paste here.
I tried to type the code so that you understand it. I am sorry for any

New entered value does not sum with previous value in owl file

[neha gupta]

Hello this does not sum the newly entered goals with the one already saved
in my owl file. Every time I enter new goal (integer value), new data is
saved and does not added(sum) with previously entered values.

* int goalsss = soln.getLiteral("goal").getInt() ; //return integer value*
*int totalgoals=goalsss+totalgoals;   // total goals initial value is 0*

*Literal p = model.createTypedLiteral(totalgoals);*
* team.setPropertyValue(goals, p);// here goals is property name*


OntModel model=ModelFactory.createOntologyModel();
InputStream in =FileManager.get().open("D://ont/soccer.owl");
if (in==null) {
throw new IllegalArgumentException( "File: " +  " not
there");
}   model.read(in,"");
 String ns="http://www.semanticweb.org/neha/ontologies/2016/6/
untitled-ontology-11#";

 OntClass team = model.getOntClass(ns + "Team");
OntProperty goals=model.getOntProperty(ns+ "Goals");

//Goals  are entered by admin, so I want to sum the newly entered
 //goals with previous stored in ontology.
//This is why I need integer values from these properties.

SELECT  *" +
" WHERE {  ?x rdf:type  ont:Team . ?x ont:Goals  ?goal  )
 ";


Query query = QueryFactory.create(queryString) ;
 QueryExecution qexec = QueryExecutionFactory.create(query,
model);
 ResultSet results = qexec.execSelect() ;
 while(results.hasNext()){
  QuerySolution soln = results.nextSolution() ;
 int goalsss = soln.getLiteral("goal").getInt() ;
int totalgoals=goalsss+totalgoals;
Literal p = model.createTypedLiteral(totalgoals);
 team.setPropertyValue(goals, p);// here goals is property name

Thank you Lorenz, yes I am really enjoying learning Jena and also enjoying

However, still I did not receive any guidance from my earlier question.

*how can we add/sum  data property values (newly entered) with previous
ones?*

I am sorry Lorenz for late reply. It gives me the now the integer number. I
do not know even now how, but I made some random changes to the code and it

Re: Typed value Exception

[neha gupta]

I just want to get the integer value from data property "Goals".


//Goals is already a data property in my owl file and it has integer value.
OntProperty goals=model.getOntProperty(ns+ "Goals");

How can I get this integer value for future arithmetic operations.

adding data values

[neha gupta]

I want to store team goals after each match. Team(Manchester for ex) Goals
2. Goals is data property in Protege.. After another match , another entry
of goals is entered and stored. Each time it is saved as 2, 1, 3 but  I
need to add the new value with previous ones like 2+1+3=6.

So how can we add data propert values (newly entered) with previous ones?

Thank you.

Re: Ontclass vs OntResource

[neha gupta]

I am confuse about RDF Resource, with createResource() I do not know a
class is created, an individual or a property is created?

Man drives Car.
Man and Car are classes here, drives predicates, so in this case what will
be the Resource?

Calculating numeric values of Data property in Ontology

[neha gupta]

I have data properties in my ontology as: Java score=55, another data
property C++ score=60, and lets suppose Semantic web score=80. Can we add
these three scores in Jena and if yes how?

But we have to do it for each instance of Student like student1, student2
etc

 Property prop1= model.getProperty(ns,"JavaScore");

 Property prop2= model.getProperty(ns,"C++Score");
 Property prop3= model.getProperty(ns,"Semantic webScore");

student1.addLiteral(prop, javascore);
student1.addLiteral(prop, c++score);
student1.addLiteral(prop, semanticweb score");   etc

Creating individuals if not already exists

[neha gupta]

I have created Students individuals in Jena and stored them in a file.
Every time students login, updates their information like GPA and updates
stored in the file.
Student.createIndividual(ns, stdName);

With this statement, suppose a student Neha is created with her information
in the file. Next time, she login, again a new instance will be created
when the application executes
*Student.createIndividual(ns, stdName);?*

*Is there any condition which states if the individual not already exists,
create it otherwise skip createIndividual statement?*

Re: Derefrencing URI

[neha gupta]

Hello Soroka thanks for your reply.

Actually I know these basics. I have read the owl file in Jena, run SPARQL,
execute it and display the question/answers(required output).

What I need is to download/show  the rdfs:comment or rdfs:abstract of the
ten resources(ten cities of Europe Berlin, London) from dbpedia in a
page/document .

Can I do it if I hard code them in the rdfs:comment in Protege with each
question and display it along the answer of the question?

Dear Soroka, I do not know how to use Gist etc but if this mailing list
support attachment , I can attach the owl file.. Jena code, I did not try
it because I am totally clueless how can I do it?

In one statement, my question is can I get rdfs:comments of , say ten
resources, of dbpedia using Jena methods?
Thanks.

Re: Derefrencing URI

[neha gupta]

I am working on undergrad project. The detail is I have owl file where I
included ten questions about European cities like Born city belongs to
which country? The resources/answers are imported from dbpedia in Protege
Individual tab. I then used Jena API. The questions/answers work fine.

The point where I have problem is I want a document/file etc where I
include the rdfs:comments or rdfs:abstract of these cities so that the
users knows about the resources.

I mean when users finishes all the ten questions, at the end he/she gets
rdfs:comment details about these resources in a document or so.If this is
not possible, then please suggest me some soloutions which is near to it.

I hope I conveyed my message?

Derefrencing URI

[neha gupta]

I want the rdfs:comment of European capital cities in one file using Jena.
While studied a lot about it, I still have no idea how to do this. I can do
it of individual resource using Virtuoso but combining these into one file
using Jena is currently beyond my knowledge.
Also what is Dereference URI to RDF?

Kindly if some one can help me here.

Re: query not working

URI? I have used the prefixes in my query.

User have to select taught or research in combo box and I need to filter my

When I dont use user selection and direct use like this:

select ?student where {?student my:hasClass my:taught}
it works but I need to use the string value here entered by user.

Querysoloution return same individual

[neha gupta]

Select *  + where {  ?Employee   rdf:type  emp:Employee }";This return
three individuals.

I use then it to assign to three radiobuttons but it assign one (same)
individual to all three radiobuttons. Where is the mistake in code.

while(result.hasNext()) {

 QuerySolution sol = result.nextSolution();

 RDFNode x=sol.getResource("?Employee");

Adding multiple individuals

[neha gupta]

Thank you Admin for adding me.
I am Neha and in the final semester of my Bachelor degree. My project is in
Semantic web and Jena, unfortunately.
I have read a lot about Jena and knows how to create classes and
individuals. I know how to create single individual and assign it to a
variable like

Individual janeSmith = class.createIndividual(ns + "Jane");

If we have to create two or three individuals, we will assign it to
variables and will print or do something with it.

My question here is what if we have to create hundreds of individuals and
we do not know the limit of individuals.

There are some other questions but I will try to figure it out, if could
not, will ask here.

I will be very thank full for help.
