P3: Filter NIF log messages

[m1ci]

There are log messages in the NIF output. I believe most people dont care about these log messages so they generate noise. My suggestion: We create a log filter in ConversionServices that filters out NIF log messages from a Jena model. This filter is enabled by default. We create an optional GET parameter “logging=true” that disables the filter.

This is e-Entity related feature, and I do not see reason this to be part of the ConversionServices. BTW, log messages are good for debugging, also there provide very useful metadata information.

<urn:uuid:1eb52471-ce7e-4761-a161-07fb201be3ba>
    a             rlog:Entry ;
    rlog:date     "2015-04-27T13:09:22.072Z"^^xsd:dateTime ;
    rlog:level    rlog:DEBUG ;
    rlog:message  "Finished creating 1 sentence(s) with 4 word(s) " ;
    dc:creator    "org.nlp2rdf.implementation.spotlight.SpotlightWrapper" .

<urn:uuid:0ef8de6c-9517-47bd-a6eb-c20f202b006c>
    a             rlog:Entry ;
    rlog:date     "2015-04-27T13:09:22.292Z"^^xsd:dateTime ;
    rlog:level    rlog:DEBUG ;
    rlog:message  "Annotated 1 nif:Context(s)  in 224.0 ms. (avg 224.0) producing 71 triples" ;
    dc:creator    "org.nlp2rdf.implementation.spotlight.SpotlightWS" .

I wouldn't call this noise. But, yes, we can implement such logging parameter. Let's see what other say.

We can introduce this functionality in the second prototype.

no log messages in the FREME NER. The log are part of the DBpedia Spotlight implementation which we don't maintain.

[m1ci]

fixed, log messages are filtered out. The changes will be deployed in the following hours.

[m1ci]

no more log messages in the output. See http://api-dev.freme-project.eu/current/e-entity/dbpedia-spotlight/documents/?informat=text&input=Berlin+is+in+Germany&outformat=turtle

If everything is OK, please close the issue. Thanks!
