NER for commands extraction

Project Title: Implementation of a Deep Learning Model for Command Extraction from User Queries

Project Overview:

This project focuses on developing an advanced natural language processing (NLP) model capable of extracting actionable commands from user queries. By leveraging the capabilities of deep learning, we aim to build a robust system that can interpret and process human language with a high degree of accuracy.

Key Components:

1. Model Selection and Framework:
   • We utilize the ktrain framework, which is a lightweight wrapper for Keras, simplifying the process of building, training, and deploying deep learning models.
   • Our primary model is a BiLSTM (Bidirectional Long Short-Term Memory) combined with a BERT (Bidirectional Encoder Representations from Transformers) model. This hybrid approach takes advantage of BERT’s contextual language understanding and BiLSTM’s sequential processing capabilities.
2. Model Fine-Tuning:
   • The BiLSTM-BERT model undergoes fine-tuning to adapt to our specific task of command extraction. Fine-tuning involves training the pre-trained BERT model on our dataset to improve its performance in recognizing and extracting commands from user queries.
   • This process includes adjusting hyperparameters, optimizing the learning rate, and incorporating dropout techniques to prevent overfitting.
3. Dataset Preparation:
   • We compile a comprehensive dataset comprising various user queries, each annotated with the corresponding commands. This dataset is essential for training and evaluating the model.
   • Data augmentation techniques are applied to enhance the diversity and size of the dataset, ensuring the model generalizes well to new, unseen queries.
4. Model Training and Evaluation:
   • The training process involves multiple iterations, with regular evaluation using metrics such as precision, recall, F1-score, and accuracy to measure the model’s performance.
   • We implement cross-validation techniques to validate the model’s effectiveness and ensure it performs consistently across different subsets of the data.
5. Deployment and Application:
   • Once trained, the model is deployed as part of a larger NLP system capable of interacting with users and executing commands based on their queries.
   • The deployment phase includes integrating the model into a user interface, allowing for real-time command extraction and execution.

Outcome and Future Work:

• Research Paper Submission:

  • The findings and methodology of this project have been documented and submitted as a research paper to the MLPC 2021 challenge organized by James at ENSPY (École Nationale Supérieure Polytechnique de Yaoundé).
  • The paper detail the model architecture, training process, evaluation metrics, and results, providing valuable insights into the application of deep learning in command extraction tasks.

• Potential Enhancements:

  • Future improvements may include expanding the dataset, exploring other model architectures, and incorporating additional NLP techniques to further enhance the accuracy and robustness of the system.
  • Collaboration with other researchers and participation in related challenges can provide opportunities for continuous learning and innovation in this domain.
