Jeremy Webb, over at the Asia Digital Map blog, has a great list of Chinese terms for the social media web:
Location-based service: 定位服务 dìngwèi fúwù
Augmented reality: 现实增强 xiànshí zēngqiáng
Desktop client: 桌面客户端 zhuōmiàn kèhùduān
Mobile phone client: 手机客户端 shǒujī kèhùduān
App (iPhone etc.): 应用程序 yīngyòng chéngxù
…
As I’ve been using iVocabulary to study vocabulary, I added all the terms into the ProVoc (dng) format.
If you have a Mac, the file is available here (zip).
