Originally, it is:

 function isNegation(node) {
     var value;

     value = node.toString().toLowerCase();

     if (
         value === 'not' ||
         value === 'neither' ||
         value === 'nor' ||
         /n['’]t/.test(value)
     ) {
         return true;
     }

     return false;
 }

I found more negations...
for example, "please improve" is negative...
and tried to improve...

 function isNegation(node) {
     var value;

     value = node.toString().toLowerCase();

     if (
         value === 'not' ||
         value === 'neither' ||
         value === 'nor' ||
         value === 'never' ||
         value === 'nobody' ||
         value === 'none' ||
         value === 'nothing' ||
         value === 'nowhere' ||
         value === 'few' ||
         value === 'hardly' ||
         value === 'little' ||
         value === 'rarely' ||
         value === 'scarcely' ||
         value === 'seldom' ||
         value === 'please' ||
         /n['’]t/.test(value)
     ) {
         return true;
     }

     return false;
 }

But failed. The result for
"not good" = -3
"never good" = +3 (which should be -3)

Anything missed out?

The text "This product is not bad at all." will be classified as bad (based on the demo) whereas the meaning is actually good.

I am not sure how hard it would be to implement negation though, but I believe this piece of text is not uncommon so the case should be handled.

Hi, do I have to make a pull request to add to the sentiment data list?

New word is "ultimate".

Thanks

Not really sure what this is supposed to reference.

I am working on a twitter-sentiment project and I have been struggling to attach the polarity of each tweet to my data. There must be something I am not understanding. Polarity is not being attached, instead 'data.sentiment' returns undefined. Thanks for all your help. Here is my code:

tweet.stream('statuses/filter', { track: 'dallas' }, function(stream) {
stream.on('data', function (data) {
//run sentiment and attach to data
retext().use(sentiment).use(function () {
return function (cst) {
console.log(inspect(cst));
};
}).process(data.text);
data.sentiment = data.polarity;
io.sockets.emit('tweet', data);
//console.log(data.user.location);
//console.log(data.tweet.location);
console.log(data);

});
});
