动机
生物医学文献是生物信息学领域知识挖掘的重要信息来源之一。尽管英语是该领域中最广泛使用的语言，但近年来，自然语言处理社区对处理英语以外的语言的兴趣越来越大。然而，适当处理非英语文本的语言资源和工具的可用性落后。我们的研究关注的是在西班牙语，这可以被认为是一个资源不足的语言，生物医学文本处理有关的生物医学文本的语义注释。
结果
我们已经进行了实验，以评估几种方法的有效性，在西班牙语的生物医学文本的自动注释。一种方法是基于语言分析的西班牙语文本和他们的注释使用信息检索和概念消歧的方法。第二种方法利用西班牙语-英语机器翻译过程来注释英语文档并将注释转换回西班牙语。第三种方法利用这两种程序的组合。我们的评估表明，一个组合系统具有竞争优势，超过两个单独的程序。

MOTIVATION
Biomedical literature is one of the most relevant sources of information for knowledge mining in the field of Bioinformatics. In spite of English being the most widely addressed language in the field, in recent years there has been a growing interest from the natural language processing community in dealing with languages other than English. However, the availability of language resources and tools for appropriate treatment of non-English texts is lacking behind. Our research is concerned with the semantic annotation of biomedical texts in the Spanish language, which can be considered an under-resourced language where biomedical text processing is concerned.
RESULTS
We have carried out experiments to assess the effectiveness of several methods for the automatic annotation of biomedical texts in Spanish. One approach is based on the linguistic analysis of Spanish texts and their annotation using an information retrieval and concept disambiguation approach. A second method takes advantage of a Spanish-English machine translation process to annotate English documents and transfer annotations back to Spanish. A third method takes advantage of the combination of both procedures. Our evaluation shows that a combined system has competitive advantages over the two individual procedures.
