本文描述了一个新颖的搜索引擎，WithAir，它为i-mode提供内容检索，这是日本最流行的手机服务。WithAir允许用户通过关键字/目的预测导航，平均只需4.4次按键即可完成典型的搜索任务。这两种导航形式分别简化了关键字输入和搜索结果输出。WithAir已经被用来搜索130万个i-mode页面，这些页面是由基于文档类型的集中爬虫收集的，它们可以区分i-mode页面和网页，准确率达到99%。此外，WithAir还提供了从130万个i-mode页面中提取的37万个区域信息页面的新鲜和详尽的搜索，精度达到93%。
This paper describes a novel search engine, WithAir that provides contents retrieval for i-mode, the most popular cell-phone service in Japan. WithAir allows users to complete typical search tasks with 4.4 keystrokes on average through keyword/purpose-predictive navigation. These two forms of navigation simplify, respectively, keyword input and search result output. WithAir has been used to search 1.3 million i-mode pages collected by document-type-based focused crawlers that can distinguish between i-mode pages and web pages with a precision of 99%. Additionally, WithAir offers fresh and exhaustive searching of 370,000 regional information pages extracted from 1.3 million i-mode pages with a precision of 93%.
