Frameworks that support general text mining, e.g., the General Architecture for Text Engineering (GATE) (Cunningham et al., 2011), provide "local interoperability" for tools available from within the framework, but there is no interoperability with tools or components available from outside the framework that the user might wish to use.
the LAPPS Grid provides interoperable access to tools in various UIMA systems as well as tools from GATE, which can be pipelined within the LAPPS Grid without the need for I/O format conversion.
