kandi X-RAY | Twitter-Sentiment Summary
Sentiment analysis is the task of determining the sentiment of a given expression in natural language, It is essentially a multiclass text classification text where the given input text is classified into positive, neutral, or negative sentiment. But the number of classes can vary according to the nature of the training dataset. This project aims to build a sentiment analyzer specifically for twitter domain.

I'm trying to download this dataset from github in a colab R notebook.
I've tried using the magic !git clone https://github.com/guyz/twitter-sentiment-dataset.git
but it does not work with an R notebook.
Are there any other possibilities to retrieve the dataset?

Answered 2018-Jan-03 at 16:22Found the solution, and it was in fact simple! Posting the answer here, to help others facing a similar issue, because I was totally stuck on this for 2 days!
My issue was caused by a dependency update.
Socket.io V 2.0.0 is not backward compatible.According to the release notes:
The new (V 2.0.0) major release brings several performance improvements, but also snuck into the bottom of the release notes was this:
This release is not backward-compatible, due to:
- A breaking change related to utf-8 encoding in engine.io-parser (socketio/engine.io-parser#81)
- an update to make the socket id on the client match the id on the server-side (socketio/socket.io-client#1058)
Please note that if you are using a self-signed certificate, rejectUnauthorized now defaults to true (socketio/engine.io-client#558).
Here's the full V2 release notes: https://github.com/socketio/socket.io/releases/tag/2.0.0
The solution is to use HTTPSMake your app https, or sign your own requests, as per documentation. As a quick fix though, I just downgraded back to socket.io V 1.7.0 and it works perfectly

Answered 2019-Dec-19 at 15:22You absolutely do want the x_validation
to be related to the y_validation
, i.e. correspond to the same rows as you had in your original dataset.
e.g. if Validation takes rows 1,3,7 from the input x, you would want rows 1, 3, 7 in both the x_validation
and y_validation

QUESTION
I'm looking for a way to get a list of unique words in a column of strings in a DataFrame.
...ANSWER
Answered 2019-Nov-24 at 00:13if you have strings in column then you would have to split every sentence into list of words and then put all list in one list - you can use it sum()
for this - it should give you all words. To get unique words you can convert it to set()
- and later you can convert back to list()
But at start you would have to clean sentences to remove chars like .
, ?
, etc. I uses regex
to keep only some chars and space. Eventually you would have to convert all words into lower or upper case.
QUESTION
I'm using the Naive Bayes Classifier from nltk to perform sentiment analysis on some tweets. I'm training the data using the corpus file found here: https://towardsdatascience.com/creating-the-twitter-sentiment-analysis-program-in-python-with-naive-bayes-classification-672e5589a7ed, as well as using the method there.
When creating the training set I've done it using all ~4000 tweets in the data set but I also thought I'd test with a very small amount of 30.
When testing with the entire set, it only returns 'neutral' as the labels when using the classifier on a new set of tweets but when using 30 it will only return positive, does this mean my training data is incomplete or too heavily 'weighted' with neutral entries and is the reason for my classifier only returning neutral when using ~4000 tweets in my training set?
I've included my full code below.
...ANSWER
Answered 2019-May-26 at 22:06When doing machine learning, we want to learn an algorithms that performs well on new (unseen) data. This is called generalization.
The purpose of the test set is, amongst others, to verify the generalization behavior of your classifier. If your model predicts the same labels for each test instance, than we cannot confirm that hypothesis. The test set should be representative of the conditions in which you apply it later.
As a rule of thumb, I like to think that you keep 50-25% of their data as a test set. This of course depends on the situation. 30/4000 is less than one percent.
A second point that comes to mind is that when your classifier is biased towards one class, make sure each class is represented nearly equally in the training and validation set. This prevents the classifier from 'just' learning the distribution of the whole set, instead of learning which features are relevant.
As a final note, normally we report metrics such as precision, recall and Fβ=1 to evaluate our classifier. The code in your sample seems to report something based on the global sentiment in all tweets, are you sure that is what you want? Are the tweets a representative collection?
QUESTION
I followed the tutorial here: https://towardsdatascience.com/creating-the-twitter-sentiment-analysis-program-in-python-with-naive-bayes-classification-672e5589a7ed to create a twitter sentiment analyser, which uses naive bayes classifier from the nltk library as a way to classify tweets as either positive, negative or neutral but the labels it gives back are only neutral or irrelevant. I've included my code below as I'm not very experienced with any machine learning so I'd appreciate any help.
I've tried using different sets of tweets to classify, even when specifying a search keyword like 'happy' it will still return 'neutral'. I don't b
...ANSWER
Answered 2019-May-21 at 07:51Your dataset is highly imbalanced. You yourself mentioned it in one of the comment, you have 550 positive and 550 negative labelled tweets but 4000 neutral that's why it always favours the majority class. You should have equal number of utterances for all classes if possible. You also need to learn about evaluation metrics, then you'll see most probably your recall is not good. An ideal model should stand good on all evaluation metrics. To avoid overfitting some people also add a fourth 'others' class as well but for now you can skip that.
Here's something you can do to improve performance of your model, either (add more data) oversample the minority classes by adding possible similar utterances or undersample the majority class or use a combination of both. You can read about oversampling, undersampling online.
In this new datset try to have utterances of all classes in this ratio 1:1:1 if possible. Finally try other algos as well with hyperparameters tuned through grid search,random search or tpot.
edit: in your case irrelevant is the 'others' class so you now have 4 classes try to have dataset in this ratio 1:1:1:1 for each class.

I am using circleci to automatically deploy my python package to PyPi when a new tag is being pushed to GitHub. I've been following this tutorial
My workflow is failing with the error home/circleci/project/twitter_sentiment/bin/python: No module named twine
I've tried to make sure twine was installed prior to calling the twine command. I've also tried to call the twine command with python -m twine
From my understanding, it seems that twine is not added to the path of the container - which causes the command not found
error.
How would I go about solving this error?
