In this investigation we discuss powerful yet efficient retrieval mechanism for news stream. Difficulty comes from the fact how to manage incremental information while keeping efficiency. Recently random projection has been paid much attention on dynamic dimensionality reduction. We show this novel technique is really useful for querying news stream in terms of cost and accuracy. We examine some experimental results and excellent efficiency in computation and memory usage.
