Associated with Vellore Institute of TechnologyAssociated with Vellore Institute of Technology This project involves utilizing machine learning techniques such as TF-IDF, Naive Bayes, and Logistic Regression for classification purposes. Classification Techniques: The data is classified into subclasses based on sentiment polarity, with features extracted using techniques like TF-IDF. Machine learning models like Naive Bayes and Logistic Regression are employed for sentiment analysis and depression detection. To assess the performance of the classification models, evaluation metrics such as F1 score, accuracy, precision, and recall were used. Balanced values of these metrics indicated the effectiveness of the models in accurately detecting depression signs in social media data.

2. PROBLEM STATEMENT:
• Depression is one of the most common public health concerns.
• Social media platforms have become ubiquitous in our lives, providing a wealth of data that
researchers can leverage to gain insights into mental health conditions.
• Depression is a pervasive and often undiagnosed in the initial stages.

6. RESEARCH OBJECTIVES:
•Use machine learning models and sentiment analysis techniques for early detection of depression
•Early detection of depressive symptoms in depressed people.

7. Data Collection: Gather data from social media where users express their feelings and emotions. We are using
Sentiment140 dataset containing 1.6 million tweets.
Preprocessing: Clean and preprocess the collected data, including text, emoticons, and emojis, to prepare it for
analysis. This process involves removing stopwords. user mentions, url, digits. Stemming and Tokenization is also
done in this step.
Feature Extraction: Extract relevant features from the data, such as emotional words, sentiment scores, and
linguistic patterns, to capture correlations between different aspects of users' writings and depression we are going to
TD-IDF for feature extraction.
PROPOSED SOLUTION:

8. Classification: Utilize machine learning techniques for sentiment analysis and depression detection. We
have used Logistic Regression and Naïve Bayes for classification.
Model Training and Evaluation: Train and evaluate machine learning models using the extracted
features and sentiment analysis to predict the level of depression in social media users' posts
Prediction : The last step is to test the developed model for using an unseen data.

9. ARCHITECTURE DIAGRAM OF PROJECT WORK :
The Sentiment140 dataset underwent a series of preprocessing
steps to ensure optimal performance of the classifiers.
After preprocessing the data, the next step was feature
extraction. In this study, the Term Frequency-Inverse Document
Frequency (TF-IDF) was used for feature extraction.[11]
We used Logistic regression which is a linear classifier and it is
a widely used classifier in Natural Language Processing (NLP)
[12].
We also used another classifier i.e. Naïve Bayes which assumes
conditional independence between pair of features, which is
used for sentiment analysis [13].

10. We are using Sentiment140 dataset containing 1.6 million tweets.
The dataset has two sentiments namely, negative(0) and positive(4).
The dataset is intended for use in sentiment analysis and machine learning tasks related to identifying
depressive content on Twitter.
The dataset can be utilized for training machine learning models to detect depression in social media
content, particularly on the Twitter platform.
DATASET DESCRIPTION :

11. MODULES IDENTIFIED :
Data Collection Module: Collect social media data from Sentiment140 where users expressed their
emotions and feelings.
Preprocessing Module: Clean and preprocess the collected data to prepare it for analysis.
Feature Extraction Module: Extract relevant features from the data, such as emotional words, sentiment
scores to capture correlations between different aspects of users' writings and depression
Classification Module: Utilize machine learning techniques for sentiment analysis and depression
detection,
Model Training and Evaluation Module: Train and evaluate machine learning model using the
extracted features and sentiment analysis to predict the level of depression in social media users' posts
Prediction Module : In this module, we used our classification models to predict the sentiment of an unseen
text. The new input text is first transformed into a numerical format using the same vectorizer that was used during
the training phase.

12. IMPLEMENTATION:

14. EVALUATION METRIC:
Both models performed well on the binary classification task, with Logistic
Regression achieving slightly higher accuracy. The choice between these two
models would depend on the specific requirements of the task. For instance, if the
cost of false positives is high, the Logistic Regression model would be a better
choice due to its higher precision.
