Natural language processing for cross-lingual information retrieval – Complete Phd and Masters Thesis

[ad_1]

Introduction

Natural Language Processing (NLP) is a branch of artificial intelligence that focuses on the interactions between computers and humans using natural language. In recent years, NLP has gained significant attention in the field of information retrieval, particularly in the context of cross-lingual information retrieval (CLIR). With the increasing amount of multilingual content available on the internet, the need for effective cross-lingual information retrieval systems has become more critical than ever.

Background of Study

The growing volume of multilingual content on the web has created a demand for cross-lingual information retrieval systems that can effectively retrieve relevant information regardless of the language in which it is written. This has led to the development of various NLP techniques and algorithms that aim to bridge the language barrier and improve the accuracy of cross-lingual information retrieval.

Problem Statement

Despite the advancements in NLP and CLIR, current systems still face challenges such as language ambiguity, translation errors, and lack of resources for lower-resource languages. These issues hinder the effectiveness and efficiency of cross-lingual information retrieval systems and limit their applicability in real-world scenarios.

Objective of Study

The main objective of this study is to develop a novel NLP-based approach to improve the performance of cross-lingual information retrieval systems. By leveraging the latest advancements in NLP techniques and methodologies, this research aims to overcome the existing challenges in CLIR and enhance the accuracy and efficiency of information retrieval across different languages.

Limitation of Study

This study is limited by the availability of resources and the scope of languages included in the analysis. Additionally, the effectiveness of the proposed approach may vary depending on the specific domain and context of information retrieval.

Scope of Study

This study focuses on the development and evaluation of a cross-lingual information retrieval system using NLP techniques. The research will primarily target popular languages such as English, Spanish, and French, with the potential for extension to other languages in future studies.

Significance of Study

The findings of this research will contribute to the advancement of NLP and CLIR technologies, providing valuable insights for researchers, developers, and practitioners in the field. The developed system has the potential to improve cross-lingual information retrieval in various industries, including e-commerce, healthcare, and education.
