Re: FW: Question about Cypher

[Sherman Monroe]

John,

This is a bug related to the new Cypher Web Service. To fix it, simply find this property and uncomment it:

cypher.http.base

The documentation on it is here. You can set the value to any URI you wish to be the default namespace for URIs minted by Cypher. This property should be option however (which is why I consider it a bug).

Let me know if this helps.

I had to recreate the repositories with the '-' instead of a space.  It did not like the space in the repository name.
Attached in the error output i am now receiving.

John,

Good to hear, now find the properties similar to this at the top of the config.ini file:

rdf.repository.lexicon=org.openrdf.repository.http.HTTPRepository,http://localhost:8080/openrdf-sesame,lexicon
rdf.repository.output=org.openrdf.repository.http.HTTPRepository,http://localhost:8080/openrdf-sesame,semantic-output
rdf.repository.dictionary=org.openrdf.repository.http.HTTPRepository,http://localhost:8080/openrdf-sesame,framenet
rdf.repository.internal=org.openrdf.repository.http.HTTPRepository,http://localhost:8080/openrdf-sesame,internal

replace it with

rdf.repository.lexicon=org.openrdf.repository.http.HTTPRepository,http://localhost:8080/openrdf-sesame,mySesameLexicon
rdf.repository.output=org.openrdf.repository.http.HTTPRepository,http://localhost:8080/openrdf-sesame,semantic output
rdf.repository.dictionary=org.openrdf.repository.http.HTTPRepository,http://localhost:8080/openrdf-sesame,framenet
rdf.repository.internal=org.openrdf.repository.http.HTTPRepository,http://localhost:8080/openrdf-sesame,internal use

The documentation has not noted this changed in the install directions (but is updated in the startup properties description).

Let me know how it goes.

Thanks,

John,

You will need to delete the cypher-cypher.jar file in the <cypher home>/lib/cypher directory, and replace it with the one attached.

Please let me know if that helps.

John,

You've discovered a bug in the startup script. Please place the attached *.jar file in the <cypher home>/lib directory. I will also release the patch in the current distribution.

I suggest you use the Cypher Web Service, which will allow you to send an input string to Cypher and receive a SPARQL file back. If you have an OWL-based schema which you want to output, then you will need to create a lexicon which maps the NL output to the OWL.

Hi John,

Currently, Cypher supports pluggable Sesame SAIL implementations, several of which are:

http://users.ecs.soton.ac.uk/wf/jsm.htm
http://sjadapter.sourceforge.net/

Using a Jena SAIL will allow you to run Cypher against a Jena repository without needing to have access to a Sesame server.

What servlet container are you using? You'll need to modify the java option parameters to include:

-DCYPHER_HOME=<cypher install directory, not cypher-ws install directory>

John,

Glad to hear.

The <cypher home>/data/repository/lexicon directory contains all the words Cypher knows about. Some verbs are know, like, speak. The foaf files contains the people Cypher knows about. Try using some of those names with these verbs, e.g. Dan knows Tim. It knows the word penny, so try Tim has a penny, Tim likes pennies. Then try extending either the grammar or lexicon to cover more input patterns.

A new service will be launched in the coming months which will allow Cypher lexicons and phrase grammars to be collaborative developed and shared by a community of linguists, developers, and Cypher users.

Hi Sherman,
I have problem with new version of cyper 1.2 which I didn't have
before with version cyper 1.1.8.
I am using for test only simple 2 txt files:
a.txt:
Tim knows Nikki
Danny knows Nikki

b.txt:
who knows Nikki

When I run cyper.bat I have some errors (didn't have before with same
files, same cypher_home, same repositories and similar config file
(it's not the same in new version)) .

I am not sure if I made something wrong with new version or there is

Thanks.
