Implementing Sentiment Analysis Using AI/ML Techniques
Project Highlights
Client Overview
A mid-sized e-commerce company was facing challenges in understanding the sentiment of their customers through reviews and feedback. With a growing user base, they needed a scalable sentiment analysis solution to provide valuable insights into customer behavior, helping them improve product offerings and customer satisfaction.
Challenges
The client needed a scalable sentiment analysis solution to understand customer sentiment from growing customer reviews and feedback.
- ✓Data Collection and Preparation
- ✓Feature Engineering
- ✓Model Building
- ✓Training the Model
- ✓Model Evaluation
- ✓Optimization
- ✓Improved Customer Insights
- ✓Scalability
- ✓Customizability
Solution
Implemented two approaches: one using a pre-trained BERT model and another custom model to provide scalable sentiment analysis.
- ✓We helped the client gather and label a dataset of customer reviews. The data was cleaned and pre-processed using tokenization, removing stopwords, and creating numerical features through techniques like TF-IDF.
- ✓We converted textual data into numerical vectors using methods such as Bag-of-Words (BoW), TF-IDF, and Word Embeddings (Word2Vec, GloVe).
- ✓Built multiple models, starting with traditional algorithms like Logistic Regression and Support Vector Machines (SVM). Also experimented with deep learning models such as RNNs and LSTMs.
- ✓Split the dataset into training, validation, and test sets. Trained the models while tuning hyperparameters to ensure optimal performance.
- ✓The models were evaluated based on metrics such as accuracy, precision, recall, and F1 score.
- ✓Further optimization was performed through grid search for hyperparameter tuning, and model ensembling to improve performance.
- ✓The sentiment analysis solution enabled the client to gain valuable insights from customer reviews, helping them to enhance their product offerings and improve customer satisfaction.
- ✓Both solutions were designed to handle large datasets and were easily scalable as the client’s customer base grew.
- ✓Whether using a pre-trained BERT model or building a custom model, we ensured that the solutions were adaptable to the client’s needs, giving them the flexibility to fine-tune based on new data.
