This document provides an overview and explanation of the key sections of code in the Ella chat bot application. Understanding these sections will aid in maintaining and extending the functionality of the application.
The useState hook is used to manage state variables inputText and chatHistory. These variables hold the user's input text and the chat history.
The handleSendMessage function is invoked when the user sends a message. It processes the user's input text, generates a response based on the detected mood, and updates the chat history accordingly.
The chat interface is rendered using React Native components such as View, Text, TextInput, and TouchableOpacity. Messages are displayed in a FlatList, allowing for smooth scrolling and rendering of chat history.
This file contains lists of words associated with different moods (happy, sad, angry, depressed). As well as neutral prompts. The generateResponse function analyzes the user's message to determine the mood and generates an appropriate response.
Responses for each mood are shuffled to provide variety and avoid repetitive interactions with Ella. Arrays containing responses are shuffled using the shuffleArray function.
To add new responses for a specific mood, simply append them to the respective array (happyResponses, sadResponses, etc.) in Dialog.js. The shuffleArray function will ensure that the responses are shuffled for variety.
To modify the response for system functions (e.g., clearing chat logs), update the systemFunctionResponses variable in Dialog.js.
To improve mood detection, you can expand the lists of mood-related words in Dialog.js or implement more sophisticated algorithms for analyzing user messages.
Understanding the structure and functionality of the code will facilitate maintenance and future development of the Ella chat bot application. Regularly reviewing and updating the code explanation document can help onboard new contributors and ensure consistency in code maintenance efforts.
