This paper will give a general overview of the venture that is machine translation with particular focus on linguistic aspects. It will display history of MT and will deal with some of the major issues in the realisation of MT like the difficulty of translating prepositions or integrating semantics, as well as the importance of real world knowledge. To illustrate these difficulties with examples on a basic level, a practice test with a moderately complex translation engine provided by Google has been carried out and will be explained. Finally, I am going to introduce three of the largest and most powerful translation machines currently in use. I will also give a brief over-view of methods of MT. The aim of this paper is to show that the realisation of the primal idea of machine translation in its original sense, which was to perform translation without human intervention (except during the construction phase of the system), is still markedly far away at present and machines are still unlikely to take over the jobs of human translators.

Objectives and Key Themes
This paper aims to provide a general overview of machine translation (MT), focusing on its linguistic aspects. It explores the history of MT, examines key challenges in its development (like translating prepositions and integrating semantics), and highlights the importance of real-world knowledge in achieving accurate translations. The paper also introduces some prominent translation machines and briefly discusses MT methods.
- The history and evolution of machine translation.
- The linguistic challenges inherent in machine translation (semantics, pragmatics, real-world knowledge).
- The limitations of current machine translation technology and its distance from achieving fully autonomous translation.
- An overview of existing major machine translation systems.
- Methods employed in machine translation.
Chapter Summaries
I. Introduction: This introductory chapter defines machine translation (MT) as a specialized software system for translating between human languages, clarifying that it's not a physical machine but a computer program. It emphasizes the interdisciplinary nature of MT development, requiring expertise in informatics, linguistics, translation, and the subject matter of the texts being translated. The chapter highlights the complexities of MT, arguing that replicating the full capabilities of a human translator—including intuition and pragmatic judgment—remains a significant challenge. It underscores the fluctuating enthusiasm for MT throughout its history, reflecting the ongoing difficulties in fully automating the process.
II. The History of Machine Translation: This chapter traces the history of MT, beginning with early ideas in the 17th century and the first patent applications in the mid-1930s. It profiles key pioneers like Andrew Booth and Warren Weaver, emphasizing the early focus on intermediary languages and the evolution of approaches from direct translation to multi-stage processes involving analysis, transfer, and synthesis. The chapter details some of the initial challenges faced by MT developers, including limited computer capabilities, cumbersome input methods, and the need for sophisticated linguistic analysis that went beyond simple lexical substitution.
III. Machine Translation in Practice: This chapter delves into the practical application of MT. It presents a case study using a Google translation engine to illustrate the difficulties in achieving accurate translations, even with advanced technology. The chapter likely discusses common errors and strategies for mitigating them to improve translation quality.
IV. Linguistic Aspects in MT: This chapter explores the core linguistic challenges in MT. It delves into semantics (meaning), pragmatics (context and implied meaning), and the crucial role of real-world knowledge in accurate translation. This section likely explains how nuanced aspects of language, such as ambiguity and cultural context, pose significant hurdles for automated translation systems.
V. Computational Linguistics: This chapter examines the computational linguistics techniques involved in MT. It outlines various methods used for translation and introduces some of the most well-known and powerful MT systems, providing an overview of their design and functionality. This chapter likely explains the underlying algorithms and processes that power these sophisticated tools.

The key themes include the history and evolution of machine translation; the linguistic challenges posed by semantics, pragmatics, and the need for real-world knowledge; the limitations of current MT technology; an overview of major MT systems; and the methods employed in machine translation.
What is the definition of Machine Translation (MT) as presented in this document?
Machine Translation (MT) is defined as a specialized software system designed for translating between human languages. It's crucial to understand that it's not a physical machine but a computer program requiring expertise in informatics, linguistics, translation, and the subject matter of the texts being translated.
What are some historical milestones in the development of machine translation mentioned in the document?
The document traces MT's history from early ideas in the 17th century and the first patent applications in the mid-1930s to the contributions of pioneers like Andrew Booth and Warren Weaver. It highlights the evolution from direct translation to multi-stage processes, the challenges of limited computer capabilities, and the need for sophisticated linguistic analysis.
What are the major linguistic challenges in machine translation?
The document emphasizes the significant linguistic hurdles in MT, focusing on semantics (meaning), pragmatics (context and implied meaning), and the crucial role of real-world knowledge. The nuanced aspects of language, including ambiguity and cultural context, are presented as significant obstacles for automated translation systems.
What are some examples of commonly acknowledged translation systems mentioned?
The document mentions LOGOS, METAL, and METEO as examples of commonly acknowledged translation systems, offering a glimpse into the variety and sophistication of existing MT tools.
What is the significance of real-world knowledge in machine translation?
