摘要:

在本文中,我们提出了一个基本的词汇语义的僧伽罗语和隐马尔可夫模型(HMM)为僧伽罗语的词性标注。在任何自然语言处理任务中,词性分析都是一个非常重要的课题,它涉及到对语言的结构、行为和动态的分析,这些知识可以用于计算语言学分析和自动化应用。虽然僧伽罗语是一种形态丰富和黏着的语言,其中单词具有各种语法特征,但标记对于进一步分析语言非常重要。我们的研究是基于统计的方法,其中的标记过程是通过计算的标签序列概率和词的可能性概率从给定的语料库,其中的语言知识是自动提取的注释语料库。目前的标记器可以达到90%以上的准确率为已知的话。

英文摘要:

In this paper we present a fundamental lexical semantics of Sinhala language and a Hidden Markov Model (HMM) based Part of Speech (POS) Tagger for Sinhala language. In any Natural Language processing task, Part of Speech is a very vital topic, which involves analysing of the construction, behaviour and the dynamics of the language, which the knowledge could utilized in computational linguistics analysis and automation applications. Though Sinhala is a morphologically rich and agglutinative language, in which words are inflected with various grammatical features, tagging is very essential for further analysis of the language. Our research is based on statistical based approach, in which the tagging process is done by computing the tag sequence probability and the word-likelihood probability from the given corpus, where the linguistic knowledge is automatically extracted from the annotated corpus. The current tagger could reach more than 90% of accuracy for known words.
