Now with 100% more charts!

Yeah right now its receiving ~600 per hour, but that has jumped to several thousand when something big is going down.

Also, Twitter is definitely an (albeit skewed) representation of the internet as a whole, since the vast majority of tweets I'm seeing are linking or referring to news stories, threads in this forum, posts on Reddit, etc., from either helpful bots or users.  So I see twitter as sort of a natural starting point for this type of thing.

Yes and yes.  The sentiment analysis is done with a probability classifier, so items it isn't sure of get put in a separate bin so I can manually classify them later and update the classifiers with this new knowledge.

Word about Bitcoin is overwhelmingly positive (http://www.whatdoestheinternetthink.net/bitcoin), so I have to run some statistics to see how the current mood compares to past mood.

Thanks, the font was just showing up too big, and I didn't plan for that.  Oops.


I'll send you a PM in a bit 


I wrote a trading bot last year, and with every traditional indicator I could throw at it, its neural network couldn't figure out how to predict price changes.  I would love for this to be a forward indicator, but if not, it might combine well with other indicators.  Worst case scenario it turns out to be a mildly interesting site and I learned a lot about programming 

I manually classified a few thousand items and trained the classifier(s) on those.  As of now I'm using bag of words, bigrams, and trigrams as features - classification accuracy seems to be pretty decent.

Holy crap - how did I miss that!?

That positive-to-negative ratio is about the average that I'm getting, which is comforting.  I'm hoping that the fluctuations in my results will be significant.

Either way though, the search for bitcoin returns ~300 hits, while I'm classifying a few times that amount per hour.  That number will increase as I add more places for the program to search.  My sentiment classifiers are also trained on the specific type of information that they'll be reading, e.g. tweets.

That's definitely coming up!  I was not aware that google trends did that, so I'll check that out for inspiration.

Yes, the functionality to do that is in place, but I'm still revising things and will probably update that pretty soon.  I was thinking about calculating a "global reach" or something like that.

That's definitely something I want to implement.  When I first started out, I was reading every tweet that was coming through, and you get some real gems.

Hello everyone,

I released my website www.objectivebitcoin.com earlier today, and I thought it might be of particular use to speculating efforts.

Basically what my service does is collect submitted content from various sites on the interwebs, classifies each bit of information as positive or negative, and compiles its findings into an indicator value.  The indicator is a z-score of averaged sentiment from the past x hours when compared to the distribution of the past y days.  X and Y are variable, as I'm still working on fine tuning the indicator to better correlate with price changes.

Right now the indicator is updating every hour, but I have plans to increase that resolution, as well as develop an API.

Let me know what you think - I'd be happy to hear any feedback you have.

Thanks for your feedback!

Interesting, I've tried the layout on a few browsers and they've all looked o.k. ( I'm on Firefox 19 on Ubuntu).  If you get the time, could you send me a screenshot so I know what you're dealing with?  I'm not a web designer by trade, so I'm sure there are things that need worked out.

If there's enough interest then I could probably eke out a mobile app in the future, sure.

Yes, that was a preliminary estimate of what I set it at.  I'm going to run some more correlations with price data to figure out what time period works best.  For lack of a better standard, price data is really the only measure I have to go off of to decide how valid the algorithm is...

Hi everyone  ,

I wanted to release to you a project I've been working on for the past month - www.objectivebitcoin.com.  Basically the goal is to keep up with what people are saying on social media and online communities, automatically classify the seniment of anything relevant, and compile those statistics into an indicator.

A negative value for the indicator means that sentiment is trending negative, while a positive value means that sentiment is trending positive.  The indicator is a z-score of the average sentment rating of the past hour, compared to the average sentiment rating of the past day or two. I did it this way because most of what I'm finding at the moment is overwhelmingly positive.

My algorithm is still fairly basic, and I plan to upgrade that as I work on it.  I'll also calculate a correlation value (with change in exchange rate) based on running the current algorithm on historic data.

I would be grateful for any and all feedback you may have!  I'm here to provide a service to the Bitcoin community.

I like this way of putting it.

I don't think making money is necessarily bad.

What is bad for Bitcoin is when people attempt to manipulate the market, scam, etc.

People profiting from Bitcoin by offering goods and services is what we need.  People spending those bitcoins is even better.

Interesting, I might post a bet on the Pens the next time they play.

Good luck to you and your new site!

Haha OK, fair enough.  It looks kind of sketchy to me, but ideally you could try it out by buying a very small amount and seeing if they deliver.  Considering that the smallest denomination is 10BTC, it seems like kind of a gamble.

Basically you can have a third-party or arbiter decide if the exchange was completed.
