Random error named broken line for same data, same query and same code.
Hello everyone,
I am trying to execute a SPARQL query by making a call to fuseki server
running at default port 3030. The query is as follows.

Data set used to query upon is the synthetic data generated using data
generator script available at http://swat.cse.lehigh.edu/projects/lubm/
(UBA 1.7) with command 3 university as the command line argument and name
space as http://example.com;
*Problem* : When I try to run the code to submit query using
QueryEngineHTTP I get an error mainly *broken line : some text*, and each
time I run the code to query dataset I get different type of text like
broken line (new line) : ty, broken line (new line) : www.
I tried to peep in the generated data, but I was not able to find any new
line in the file or any error.
Interestingly, when data is generated using above script UBA 1.7 with 1
university as argument I get no such error for the same query (may be
number of triples are one third when compared with 3 as argument).

Flow from Fuseki to ARQ
Hello everyone, Can any one tell me, as what ARQ (com.hp.hpl.jena.query create/make) classes/functions is called when I write a query in Fuseki 1.0.1 ? Thanking you in advance. Regards, Ankur Padia.
Possibility of manipulation in ARQ
Hello everyone, I am new to ARQ (SPARQL Engine) of Jena. I wanted to know is it possible to manipulate the subject or object part of the triple after calling execute function (e.g. execSelect) and before getting result. Moreover, is there any documentation that describes query life cycle i.e form the query string how each part of the query is handled. Thanking you, in advance. - Ankur Padia.
Need of a Data set to measure goodness of Similarity function
Hello everyone, I am a PhD student working in domain of Semantic Web. I have defined similarity function to measure the amount of overlapping between two given ontological definition. Currently I am searching a way to determine how good the defined functions are but out of luck. I have seen OAEI (Ontological Alignment and Evaluation Initiative)[1] but it focuses on the alignment which is problem that does not take lexicon under consideration (i.e. Same definition may be labelled differently for example D = A Intersection B in Ontology 1 while in other ontology it could be E = A intersection B). Even sample ontology containing derived concepts defined using only Union and Intersection is also fine. Any help or guide line would be appreciated. - Ankur Padia.
