Indexing dan Searching Document Menggunakan Metode Semantic Suffix Tree Clustering Berbasis Android

David Valentino, Adi Wibowo, Justinus Andjarwirawan


Anroid smartphone device has been involved in user’s way of living in this modern era. Smartphone device is used in user’s daily activity such as reading and storing electronic document in Pdf, Word and other file formats. User might and frequently forgot elctronic document’s directory in the smartphone.

This research aims to help user to find documents that reflect user’s keyword semantically or literally. Documents that reflect user keyword semantically or literaly will be shown. Various method is tested to minimize time use in clustering using suffix tree to semantic searching processes.

This research finds that user could find documents in the smartphone that reflect user’s keyword. Average time use for clustering about 100 documents containing 1000 word for each document is 686.7 seconds. User is able to search for document right after clustering process is done. Average time use for document searching is less than 2 seconds. Hence, thread implementation for processes decrease time consume greatly and the search result displayed to the user represents document content semantically.
