Cascaded search for similar documents between mobile devices

This paper presents a novel method for searching documents which have similar topics to a given document set. It is designed for mobile device users to search for documents which have similar topic to the ones on the users own device. The algorithms are designed for slower processor and memory capacity, and small data traffic between the devices. These features allow the application in an environment of mobile devices like phones or PDA-s. The keyword list based topic comparison is enhanced with cascading, leading to a series of document searching elements specialized on documents not selected by previous stages. Details on the applied methods and experimental results are presented in this paper.
