跨语言信息检索（CLIR），其中查询和文档是在不同的语言，最近已成为信息检索界的主要课题之一。本文提出了一个日/英CLIR系统，其中我们结合了联合收割机的查询翻译和检索模块。我们目前的目标是检索技术文档，因此我们的系统的性能在很大程度上取决于技术术语翻译的质量。然而，专业术语的翻译仍然存在问题，因为专业术语通常是复合词，因此新术语是通过组合现有的基础词来逐步创建的。此外，日语还经常以其特殊的表音符号来表示外来词。因此，现有的词典很难达到足够的覆盖面。为了解决第一个问题，我们制作了一个基本词的日英词典，并在逐字的基础上翻译复合词。我们还使用了概率方法来解决翻译歧义。对于第二个问题，我们使用了音译的方法，将基础词典中未列出的单词对应到目标语言中的语音对应。我们使用CLIR的测试集来评估我们的系统，并表明复合词翻译和音译方法都提高了系统的性能。
Cross-language information retrieval (CLIR), where queriesand documents are in different languages, has of late become one ofthe major topics within the information retrieval community. Thispaper proposes a Japanese/English CLIR system, where we combine aquery translation and retrieval modules. We currently target theretrieval of technical documents, and therefore the performance of oursystem is highly dependent on the quality of the translation oftechnical terms. However, the technical term translation is stillproblematic in that technical terms are often compound words, and thusnew terms are progressively created by combining existing basewords. In addition, Japanese often represents loanwords based on itsspecial phonogram. Consequently, existing dictionaries find itdifficult to achieve sufficient coverage. To counter the firstproblem, we produce a Japanese/English dictionary for base words, andtranslate compound words on a word-by-word basis. We also use aprobabilistic method to resolve translation ambiguity. For the secondproblem, we use a transliteration method, which corresponds wordsunlisted in the base word dictionary to their phonetic equivalents inthe target language. We evaluate our system using a test collectionfor CLIR, and show that both the compound word translation andtransliteration methods improve the system performance.
