Introduction

Natural Language Understanding (NLU) is a field of artificial intelligence that focuses on the ability of machines to comprehend and interpret human language in a way that is meaningful. With the rise of virtual assistants such as Siri, Google Assistant, and Alexa, the importance of NLU in enabling these assistants to provide context-aware responses has become increasingly apparent. Context-aware virtual assistants have the ability to understand the user’s situation and environment, allowing them to provide more personalized and relevant assistance.

Background of Study

The field of NLU has seen significant advancements in recent years, with research focusing on improving the accuracy and efficiency of language understanding algorithms. The development of context-aware virtual assistants has also gained traction, with companies investing heavily in the technology to enhance user experiences. However, there are still challenges to be addressed in order to fully realize the potential of context-aware virtual assistants.

Problem Statement

Despite the progress made in NLU and context-aware virtual assistants, there are still limitations in their ability to accurately interpret and respond to user queries in real-time. This can lead to frustration and inefficiencies in user interactions with virtual assistants, ultimately affecting user satisfaction and adoption of the technology.

Objective of Study

The objective of this thesis is to explore the current state of NLU in the context of context-aware virtual assistants and to propose improvements to existing algorithms and methodologies. By addressing the limitations of current systems, we aim to enhance the overall user experience and utility of virtual assistants in various domains.

Limitation of Study

This study will focus on a specific subset of NLU techniques and will not cover all aspects of language understanding. Additionally, the research will be limited to virtual assistant platforms that are commercially available and widely used.

Scope of Study

The scope of this study includes a review of current literature on NLU and context-aware virtual assistants, the design and implementation of a prototype system, and an evaluation of the system’s performance in user interactions.

Significance of Study

The significance of this study lies in its potential to improve the functionality and usability of virtual assistants through advancements in NLU technology. By enhancing the ability of virtual assistants to understand and respond to user queries in context, we can enhance user experiences and drive greater adoption of the technology.
