A generalised chatbot which can intelligently respond to conversation using named entity recognition (NER), sentiment analysis and an implementation of a decision system for follow up mechanism using a Seq2seq model which uses Bidirectional RNNs and Attention models.

3. IBM Watson NLU (for sentiment analysis)

We have trained our model on three different datasets (SQuAD , Cornell Movie Dialogue Corpus and a Trump Tweets Dataset) to bring about generalisation. They are included in the 'data' folder and are included through an import of the folder.

Note - First make sure that all the files required are saved in the same directory and all the required libraries are installed before running the program. For Windows -

To run it on squad

python model.py squad

To run on cornell_corpus

python model.py cornell_corpus

To run on twitter

python model.py twitter

For Linux (For Python3+ versions) -

To run it on squad

python3 model.py squad

To run on cornell_corpus

python3 model.py cornell_corpus

To run on twitter

python3 model.py twitter

The model can be trained on the user's system or the pretrained weights (.hdf5 files) included in the respective folders can be loaded to view the output.

The results of the chatbot (including the follow up) are shown below -
