非洲词网项目(AWN)旨在建立五种非洲语言的词网：茨瓦纳语、伊西科萨语、伊西祖鲁语、塞萨托亚语、勒博亚语(又称塞佩迪语或北索托语)和齐文达语。目前，基于英语普林斯顿词网(PWN)结构的所谓扩展模型被用来继续手工开发非洲词网。这是一项劳动密集型的工作，需要由语言专家在若干考虑因素的指导下进行，例如非洲语言中一个术语的词汇化程度。到目前为止，语言学家在没有电子资源帮助的情况下负责确定和翻译适当的语法集，因为就非洲语言而言，即使是计算机可读和电子双语词表等基本资源通常也不能免费获得。最近研究了加快人工开发同义词集并减轻人类语言专家工作量的方法。这些工作主要集中在利用双语词典中现有的最低限度的信息来确定PWN中应包括在AWN中的词组，将信息从词典传输到WordNet，并将潜在的词组提交给语言学家，供他们最后批准并纳入词网。在本文中，我们描述了为构建非洲字网而开发的方法，非洲字网是自然语言处理应用程序的潜在重要资源。调查了可以利用的可用资源和必须开发的资源，并解释了初步结果和未来计划。
The African Wordnet Project (AWN) aims at building wordnets for five African languages: Setswana, isiXhosa, isiZulu, Sesotho sa Leboa (also referred to as Sepedi or Northern Sotho) and Tshivenda. Currently, the so-called expand model, based on the structure of the English Princeton WordNet (PWN), is used to continually develop the African Wordnets manually. This is a labour-intensive work that needs to be performed by linguistic experts, guided by several considerations such as the level of lexicalisation of a term in the African language. Up to now, linguists were responsible for identifying and translating appropriate synsets without much help from electronic resources because in the case of African languages even basic resources such as computer readable and electronic bilingual wordlists are usually not freely available. Methods to speed up the manual development of synsets and ease the workload of the human language experts were recently investigated. These centred around utilising the minimal amount of information available in bilingual dictionaries to identify synsets in the PWN that should be included in the AWN, transferring information from dictionaries to the wordnet and presenting the potential synsets to linguists for final approval and inclusion in the wordnets. In this article, we describe the methodology developed for building the African Wordnets, a potentially significant resource for natural language processing applications. Available resources that could be taken advantage of and resources that had to be developed are investigated, and initial results and future plans are explained.
