HINT3: Raising the bar for Intent Detection in the Wild

This repository contains datasets and code for the paper "HINT3: Raising the bar for Intent Detection in the Wild" accepted at EMNLP-2020's Insights workshop

Published paper is available here

Update Feb 2021: We noticed in our analysis of the results that there are few ground truth labels which are incorrect. Hence, we're releasing a new version, v2 of the dataset, present inside dataset/v2 folder. All the results in the paper were obtained on the earlier version of the dataset present inside dataset/v1, which should be used to exactly reproduce the results presented in the paper.

Dataset

  • Train and Test sets for SOFMattress, Curekart and Powerplay11 are available in dataset folder for both Full and Subset variations.
  • You can also use prepare_subset_of_data.ipynb notebook to generate subset variations of full datasets. All the entailment assets generated can be downloaded from here.

EDA

We have done EDA analysis on the datasets which is accessible from the data_exploration folder.

Test set predictions

Predictions from BERT and 4 NLU platforms on test sets used for analysis in the paper are present in preds folder. Feel free to do further analysis on these predictions if you want.

Test set metrics

All the metrics from BERT and 4 NLU platforms on test sets are present in results folder for further analysis. Graphs plotted in the paper can be reproduced using analysis/plot_metrics_graph.ipynb notebook

Reproducibility Instructions

The scripts to generate training data and predicting intents based on the testing data for all the 4 platforms and BERT based classifier are inside platforms folder within their named directories.

Rasa

  • The training_data_conversion.ipynb notebook is used to convert the training set into a JSON format that Rasa mandates in order to train its model. The generated JSON file is created inside the data directory

  • In order to train a model for one particular bot, keep only that bot's JSON file inside the data directory

  • Train the model using this command: rasa train nlu

  • Once the model is trained, its tar.gz file will be stored inside the models directory based on the current timestamp

  • In order to start the NLU server, run the following command: rasa run --enable-api -m models/nlu-<timestamp>.tar.gz where nlu-<timestamp>.tar.gz is the name of the model's file created in the previous step

  • In order to generate a report against a testing set file, run the generate_preds.ipynb notebook after specifying the name of the bot. Generated predictions will be stored inside preds folder

Dialogflow

  • The training_data_conversion.ipynb file is used to convert the training set into a bunch of JSON files that Dialogflow mandates in order to train its model. The generated JSON files are stored inside the intents directory

  • Login to the Diaologflow dashboard using a Gmail account and visit https://dialogflow.cloud.google.com

  • Dialogflow allows bulk upload of the training set by importing a zip file. The compressed folder has a predefined structure. In order to create this folder, create a copy of the agent_template directory and rename the folder as per your bot name. Then, copy all the JSON files created in step 1 and paste it inside the intents folder of your agent directory. Then, open the agent.json file and edit the displayName property to specify the name of the agent of your bot. An agent is analogous to an app or a bot. Once these changes are done, compress the agent directory into a zip file

  • Create a new agent on the Dialogflow dashboard here: https://dialogflow.cloud.google.com/?authuser=1#/newAgent

  • Delete Default Fallback Intent from the intents dashboard

  • Edit the agent: https://dialogflow.cloud.google.com/?authuser=1#/editAgent/mt11-agent-ugmx/ -> Export & Import -> Import from zip -> upload the agent zip file. This will allow us to bulk upload all intents along with their respective utterances

  • Go to Edit agent -> ML settings. The default threshold value is 0.3. Change it to 0.05 and Train the model

  • Copy the CURL request from the API playground. We can get the authentication token and the model's API endpoint from this CURL request

  • The generate_preds.ipynb file will help generate predictions for the bot.

LUIS

  • The training_data_conversion.ipynb file will generate a JSON file based on the training set's CSV file

  • Login to luis.ai, go to https://www.luis.ai/applications and click on New app for conversation -> Import as JSON. Upload the JSON file generated in the first step

  • Once all the intents are uploaded, click on the Train button to train the model. Once the model is trained, click on Publish followed by selecting Production slot

  • Now, go to the Manage section of the app and copy the App ID. We will be using this App ID in the generate_preds.ipynb file to generate our prediction reports

  • Go to the settings page of your account in order to get the PREDICTION_KEY and PREDICTION_ENDPOINT used in generate_preds.ipynb file

Haptik

  • Access requests for signup on Haptik are processed via contact form at https://haptik.ai/contact-us/

  • Once you get the access, you'll be able to create bots and run predictions using the scripts provided in platforms/haptik

BERT

  • Results on BERT can be reproduced using scripts in the folder platforms/bert

  • The folder also contains config for each of the models trained on Full and Subset variations of datasets

   abstract = "Intent Detection systems in the real world are exposed to complexities of imbalanced datasets containing varying perception of intent, unintended correlations and domain-specific aberrations. To facilitate benchmarking which can reflect near real-world scenarios, we introduce 3 new datasets created from live chatbots in diverse domains. Unlike most existing datasets that are crowdsourced, our datasets contain real user queries received by the chatbots and facilitates penalising unwanted correlations grasped during the training process. We evaluate 4 NLU platforms and a BERT based classifier and find that performance saturates at inadequate levels on test sets because all systems latch on to unintended patterns in training data.",
