Introduction

In today’s interconnected world, multilingual interactions are becoming increasingly common. As individuals navigate various linguistic landscapes, they often engage in code-switching, the practice of alternating between two or more languages within a single conversation. This phenomenon poses unique challenges for automated systems designed to process and understand human language. Code-switching detection is a crucial task in natural language processing that aims to identify and analyze instances of code-switching in multilingual communication.

Background of Study

With the rise of social media and global communication platforms, code-switching has become prevalent in digital interactions. Researchers have identified various reasons for code-switching, including social identity construction, efficiency in communication, and linguistic constraints. Understanding the patterns and motivations behind code-switching can provide valuable insights into language use and social dynamics in multilingual communities.

Problem Statement

Despite the increasing importance of code-switching detection in multilingual interactions, existing research in this area is limited. Automated systems often struggle to accurately identify code-switching due to the complexity and variability of linguistic patterns. Moreover, the lack of standardized methods and datasets hinders the development of robust code-switching detection models.

Objective of Study

The primary objective of this thesis is to develop a reliable and efficient code-switching detection system for multilingual interactions. By leveraging advanced machine learning techniques and linguistic knowledge, we aim to improve the accuracy and scalability of existing code-switching detection methods.

Limitation of Study

This study is limited by the availability of annotated code-switching datasets and the generalizability of the proposed detection model. Additionally, the performance of the system may vary across different language pairs and communicative contexts.

Scope of Study

This thesis focuses on code-switching detection in written text and online communication platforms. We will primarily analyze code-switching between English and Spanish, two widely spoken languages with distinct linguistic features.

Significance of Study

The findings of this research can significantly impact the development of natural language processing technologies and enhance our understanding of code-switching behaviors in multilingual communication. By improving code-switching detection capabilities, we can facilitate more accurate language processing and translation services for diverse language users.
