This document describes how to create a mashup using the RAD toolset to combine two existing web services. The mashup will take plain text as input, identify the language, and if it is English or Romanian, will pass the text to a text processing service to output processed text with part-of-speech tags and other details. It provides details on the existing Racai web services to be used, the steps to import them as entities in RAD, create a business view and integration service to combine them, and generate a new web service mashup.
