Can't run query mode or simple-freebase mode
Hello,
When I try to run this query: ./run @mode=query @sparqlserver=localhost:3001 -formula '(fb:location.location.containedby fb:en.california)'
I get the following error: Error: Could not find or load main class edu.stanford.nlp.sempre.freebase.SparqlExecutor Command failed: java -ea -cp libsempre/:lib/ edu.stanford.nlp.sempre.freebase.SparqlExecutor -SparqlExecutor.endpointUrl http://localhost:3001/sparql -formula (fb:location.location.containedby fb:en.california)
And when I try to run simple-freebase mode: ./run @mode=simple-freebase @sparqlserver=localhost:3001
I get this error: Problem processing: freebase edu.stanford.nlp.sempre.freebase.BinaryLexicon Exception in thread "main" java.lang.RuntimeException: java.lang.ClassNotFoundException: edu.stanford.nlp.sempre.freebase.BinaryLexicon at edu.stanford.nlp.sempre.Master.getOptionsParser(Master.java:443) at edu.stanford.nlp.sempre.Main.main(Main.java:38) Caused by: java.lang.ClassNotFoundException: edu.stanford.nlp.sempre.freebase.BinaryLexicon at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:264) at edu.stanford.nlp.sempre.Master.getOptionsParser(Master.java:437) ... 1 more Command failed: java -Dmodules=core,freebase -cp libsempre/:lib/ -ea edu.stanford.nlp.sempre.Main -executor freebase.SparqlExecutor -SparqlExecutor.endpointUrl http://localhost:3001/sparql -FreebaseSearch.cachePath FreebaseSearch.cache -EntityLexicon.mid2idPath freebase.cloudapp.net:4000:freebase-rdf-2013-06-09-00-00.canonical-id-map.gz -TypeInference.typeLookup freebase.FreebaseTypeLookup -FreebaseTypeLookup.entityTypesPath freebase.cloudapp.net:4000:freebase-rdf-2013-06-09-00-00.canonicalized.en-types.gz -EntityLexicon.maxEntries 2 -FeatureExtractor.featureDomains rule -Parser.coarsePrune -JoinFn.typeInference -UnaryLexicon.unaryLexiconFilePath /dev/null -BinaryLexicon.binaryLexiconFilesPath /dev/null -Grammar.inPaths freebase/data/demo1.grammar -SparqlExecutor.returnTable -Main.interactive
These errors persist despite running ./pull-dependencies freebase make freebase
Any thoughts? osmode
Hi, osmode. Could you try running ant clean and then ant? Maybe the class was not compiled correctly.
Thanks for your quick reply, ppasupat. When I run "ant clean" and "ant", I get:

This fixed half the problem. Now I can run this query: ./run @mode=query @sparqlserver=localhost:3001 -formula '(fb:location.location.containedby fb:en.california)'
However, when I try to run: ./run @mode=simple-freebase @sparqlserver=localhost:3001
I get this error:

I'll venture a guess here and say that this is a freebase connection error ("connecting to freebase.cloudapp.net:4000 ...")
I'm able to start simple-sparql mode just fine and run a few basic queries that way: ./run @mode=simple-sparql @sparqlserver=localhost:3001
Thanks very much for all of your help ppasupat.
Has anyone recently been able to run simple-freebase mode?
I'm able to run some examples in simple-sparql mode, but I would like to use my own custom triples, and this is where I'm getting stuck. I set up an Apache Jena server to do this, but I'm having trouble finding a mode that will let me take advantage of using my own RDF client. Can anyone point me in the right direction?
@osmode ,i get the same problem with you, but i also don't know how to solve it.
The command:
./run @mode=simple-freebase @sparqlserver=localhost:3001
works if I remove the following rule from demo1.grammar:
(rule $NP (actors) (ConstantFn (fb:people.person.profession fb:en.film_actor)))
I don't know why though
Basically the Virtuoso instance on the default URL (cloudapp.net) is already dead. You can still use your local Virtuoso instance though.
For the simple-freebase mode, the cache server must also be specified. To start the cache server, run:
./run @mode=cacheserver -readOnly -capacity MAX -basePath lib/fb_data
To specify a port, add @port=[portnumber] to the command. The default port is 4000.
Then try:
./run @mode=simple-freebase @sparqlserver=localhost:3001 @cacheserver=localhost:4000
If you run the SPARQL server on another port, use that port number instead of 3001.
@argoel what is the expected output of the sentence "height of tom cruise" if i run the following: ./run @mode=simple-freebase @sparqlserver=localhost:3001
Also, do i need to comment out the (rule $NP ($Str) (LexiconFn entity fbsearch)), as it says freebase search api is deprecated.
And, do i need to download the whole freebase database?
