FILTERAPP: An Android-Based Profanity Control Application Using WU-Manber Algorithm with Fault-Tolerant Searching Capability

Mary Rose A. Zamora, Benilda Eleonor V. Comendador


This study utilized a multi-pattern string matching algorithm to develop an effective android-based mobile profanity control application for children. Initially, three (3) algorithms were subjected to an experiment using a simulation program to determine which algorithm has the highest accuracy rate particularly in providing a fault-tolerant search result. To analyze the performance of each algorithm, pre-defined datasets were used in the experiment for comparative analysis. Three measures were used: Precision, Recall and F-Measure. Based on the conducted experiment, Wu-Manber algorithm has the highest accuracy rate against Aho-Corasick and Set-Horspool algorithms.
