Dear DBpedia-Spotlight Users and Devs!

As I'm using dbp-spotlight for a project of mine I came across some weird behaviour. I'm using dbpsl via REST interface and I could see that if I provide the same data to it the results' similarity score I get differs though I don't alter any parameters.

*The text would be:*
/When we think about learning our ABCs, the alphabet and the basics of language come to mind---all vital for communication. Well, we live in a time when it seems the basic ABCs of Christianity are not being taught in America as they once were. Over the years, I've met many people who teach Sunday school (or lead a youth or adult Bible study) who have told me that so much of their material now seems so watered down. In fact, as someone said to me, "I'm tired of the fluff and stuff."/

*Parameters:*
"confidence": "0.0"
"support": "30"
"types": ""
"sparql": ""
"policy": "whitelist"

*(partial) Result 1:*

    {
      "URI": "http://dbpedia.org/resource/Learning";,
      "support": "523",
"types": "Freebase:/media_common/quotation_subject,Freebase:/media_common,Freebase:/projects/project_focus,Freebase:/projects,DBpedia:TopicalConcept",
      "surfaceForm": "learning",
      "offset": "20",
*"similarityScore": "0.00971667468547821",*
      "percentageOfSecondRank": "-1.0"
    },

*(partial) Result 2:*

    {
      "URI": "http://dbpedia.org/resource/Learning";,
      "support": "523",
"types": "Freebase:/media_common/quotation_subject,Freebase:/media_common,Freebase:/projects/project_focus,Freebase:/projects,DBpedia:TopicalConcept",
      "surfaceForm": "learning",
      "offset": "20",
*  "similarityScore": "0.011633150279521942",*
      "percentageOfSecondRank": "-1.0"
    },

Funny thing is that those are the only variations I get when querieng the REST interface with the said parameters and text. Additionally those fluctuations don't seem to happen when using the demo and showing the n-best candidates!

I hope we can fix this so I don't have to exclude the similarity from my equation. If there is any additional information I could provide just tell me :).

Regards,
David

P.S.: If this double-posts I apologize for spamming but I wasn't sure if I had an active subscription. So I resubscribed and sent this again.
