明慧--Introduction

With the prevalence of digital communication networks, increasing amount of information is being generated and exchanged electronically. To effectively address the growth in data quantity, automatic processing ‘bots’ or ‘agents’ have been developed to aid human user in filtering or summarizing raw materials. With the introduction of new web standards such as XML and semantic web [1], it is expected that search, exchange, and interaction across different platforms will become more convenient and precise.

隨著網路上數位溝通的流行，藉由電子方法的產生和交換增加資訊。在資料量中有效位址的成長，全自動化程序的機器人或代理人程式已經發展成幫助使用者過濾或概括原始資料。隨著新網路的引進，像是XML和語義網路，期待於搜尋、交換、及不同平台間的互動能夠更方便且明確。


While we celebrate and enjoy the convenience of automation, it should be cautioned that abuse of technology can result in undesirable consequences. For example, scripts to register for free e-mail accounts in quantity have proliferated to such an extent that major portal sites have adopted certain anti-automation strategy to counter-attract. Automated playing ‘bots’ in the form of plug-ins can seriously interfere with the normal operation of online games and thus take the fairness and fun away from the whole experience. A simple and effective approach to automatically tell humans and machines apart will prove valuable for the aforementioned scenarios.

當我們讚頌和享受自動化方便的同時，應該小心謹慎科技的濫用所導致不受歡迎的後果。舉例來說，免費的e-mail帳戶所登記的數量已經擴散到一個範圍，讓主要部門已經採納可信的反自動化對策去破解。而自動化機器人程式以外掛的形式利用正常指令嚴重介入於線上遊戲，且將公平性和娛樂性遠離於所有的經驗。在上述的方案中，一個簡單而有效的通道自動證實人機辨識是有價值的。
