In recent years there has been an enormous boom in Computational Intelligence in Information Systems. This paperattempts to provide rich information and professional observation about the recent progress made in adapting Chinese language processing and computing industry to the new challenges arisen from rapid advancement of the Internet as well as the worldwide proliferation of mobile devices and social media. In the process of language digitization, search engine and machine translation are the two major typical areas pertinent to large scale industrialization. Through tracing the developing trajectory of these two areasas exemplar cases, we attempt to demonstrate how language digitization as a technology and industry deals with a range of new challenges, including intelligent applications and big data, such as business intelligence, social analytics, data/text mining, machinelearning, text summarization and information retrieval. In conclusion, we are optimistic for the future of the fields in achieving even better quality based on paradigm shift away from linguistic/rule-based methods towards empirical/data-driven methods which havebeen made possible by the availability of large amounts of training data and large computational resources.
