摘要:

在本文中,我们提出了我们的工作之间的统计机器翻译(SMT)和基于规则的机器翻译(RBMT)系统之间的案例研究在英语-印度langugae和印度到印度langugae的角度。本研究的主要目的是进行五方面的性能比较:a)SMT和RBMT b)SMT对英语-印度语言c)RBMT对英语-印度语言d)SMT对印度语言的角度e)RBMT对印度语言的角度。通过详细的分析,我们描述了基于规则和统计机器翻译系统的发展和评价。通过详细的误差分析,指出了两种系统的相对优势和不足。基于我们的研究的观察结果是:a)SMT系统优于RBMT b)在SMT的情况下,英语到印度语的MT系统比印度语到英语的MT系统表现得更好c)在RBMT的情况下,英语到印度语的MT系统比印度语到英语的MT系统表现得更好d)SMT系统比RBMT对印度语到印度语的MT系统表现得更好。实际上,我们将看到,即使使用少量的训练语料库,统计机器翻译系统对于高质量的领域特定机器翻译也比基于规则的对应物具有许多优点。

英文摘要:

In this paper we present our work on a case study between Statistical Machien Transaltion (SMT) and Rule-Based Machine Translation (RBMT) systems on English-Indian langugae and Indian to Indian langugae perspective. Main objective of our study is to make a five way performance compariosn; such as, a) SMT and RBMT b) SMT on English-Indian langugae c) RBMT on English-Indian langugae d) SMT on Indian to Indian langugae perspective e) RBMT on Indian to Indian langugae perspective. Through a detailed analysis we describe the Rule Based and the Statistical Machine Translation system developments and its evaluations. Through a detailed error analysis, we point out the relative strengths and weaknesses of both systems. The observations based on our study are: a) SMT systems outperforms RBMT b) In the case of SMT, English to Indian language MT systmes performs better than Indian to English langugae MT systems c) In the case of RBMT, English to Indian langugae MT systems perofrms better than Indian to Englsih Language MT systems d) SMT systems performs better for Indian to Indian language MT systems compared to RBMT. Effectively, we shall see that even with a small amount of training corpus a statistical machine translation system has many advantages for high quality domain specific machine translation over that of a rule-based counterpart.
