Google Prediction API is the most failed when it comes to NLP. Understanding the heuristics is next to impossible with it.Perhaps if you write your won genetic algorithms ,it might get the closest to detect spam and hopefully filter out spam.
Not easy as it seems since you would have to write your own model which analysis's the topic first and then filter out the spam.
If Google's Prediction API doesn't work, then I will find some other Machine Learning platform and see how well they do. If all else fails, I can attempt to figure out TensorFlow. Either way, I'm going to need the same data.Not easy as it seems since you would have to write your own model which analysis's the topic first and then filter out the spam.
Speaking practically,its impossible because model will fail most of the time since a post could be off topic but yet constructive to discussion.
That's also why I'm looking for the Topic URLs. I may be able to use the rest of the topic as context and train it to analyze the post in context.You know there are a few things bots can't beat humans at..
Some AIs are very intelligent. Especially ones on cloud platforms where there is a ton of computing power backing it.
