The Language Grid is an infrastructure for enabling users to share language resources developed by language specialists and end-user communities. The users employ the resources to support their intercultural/multilingual activities. However, there is a big gap between functions provided by the language resources and those needed by the users. To bridge the gap and satisfy users' needs, this paper extends the Language Grid by adding four language service layers: system adaptation layer, combination layer, coordination layer, and user adaptation layer. By introducing the four-layers, the Language Grid can coordinate several language resources to create new language services customized to users' activities, such as back translations, multi-hop translations, and specialized translations.
