One way to block these sites is to provide a list of sites that are categorized as negative. However, the problem is that every day new sites appear that have not been listed yet. Therefore an intelligent system that can detect the content and can automatically update the list is needed. Negative content on a website can consist of text, image, and video contents that require different parsing techniques and classifiers to separate and classify such contents. Each classifier produces a probability. Hence, an algorithm that can combine these probabilities is required. Fusion algorithm can combine the probabilities of text, images, and video contents. However, the algorithm does not work on websites which have an equal proportion of negative and positive images, i.e. grey websites. These websites require specific handling such as a cascade fusion algorithm to change the sensitivity so it can reduce the level of over blocking. The results show that after the modification of the fusion algorithm, the accuracy of the classifier increased from 91.62% to 98.49% because the rate of over blocking could be reduced.<\/jats:p>","DOI":"10.3233\/web-180391","type":"journal-article","created":{"date-parts":[[2018,11,6]],"date-time":"2018-11-06T13:14:41Z","timestamp":1541510081000},"page":"233-246","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Improvement of fusion algorithm using cascade method and implementation on proxy server for replacing negative content on a porn site"],"prefix":"10.1177","volume":"16","author":[{"given":"Yosua Alvin Adi","family":"Soetrisno","sequence":"first","affiliation":[{"name":"Diponegoro University","place":["Indonesia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Selo","family":"Sulistyo","sequence":"additional","affiliation":[{"name":"Gadjah Mada University","place":["Indonesia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ridi","family":"Ferdiana","sequence":"additional","affiliation":[{"name":"Gadjah Mada University","place":["Indonesia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Teguh Bharata","family":"Adji","sequence":"additional","affiliation":[{"name":"Gadjah Mada University","place":["Indonesia"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2018,10,31]]},"reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"crossref","unstructured":"T.B.Adji Z.Abidin and H.A.Nugroho System of negative Indonesian website detection using TF-IDF and Vector Space Model in: Electrical Engineering and Computer Science (ICEECS) 2014 International Conference on 2014 pp. 174\u2013178.","DOI":"10.1109\/ICEECS.2014.7045240"},{"key":"e_1_3_1_3_2","doi-asserted-by":"crossref","unstructured":"T.B.Adji F.Rahadian H.A.Nugroho and A.G.Persada Negative content filtering based on skin texture homomorphic filter and localizations in: Electrical Engineering and Computer Science (ICEECS) 2014 International Conference on 2014 pp. 1\u20136.","DOI":"10.1109\/ICEECS.2014.7045242"},{"key":"e_1_3_1_4_2","doi-asserted-by":"crossref","unstructured":"Z.Chen O.Wu M.Zhu and W.Hu A novel web page filtering system by combining texts and images in: Proceedings of the 2006 IEEE\/WIC\/ACM International Conference on Web Intelligence 2006 pp. 732\u2013735.","DOI":"10.1109\/WI.2006.21"},{"key":"e_1_3_1_5_2","doi-asserted-by":"crossref","unstructured":"N.Dalal and B.Triggs Histograms of oriented gradients for human detection in: 2005 IEEE Computer Society Conference on Computer Vision and Pattern Recognition (CVPR 2005) Vol. 1 2005 pp. 886\u2013893.","DOI":"10.1109\/CVPR.2005.177"},{"key":"e_1_3_1_6_2","doi-asserted-by":"publisher","DOI":"10.1109\/TFUZZ.2004.825972"},{"key":"e_1_3_1_7_2","doi-asserted-by":"publisher","DOI":"10.1162\/089976698300017197"},{"key":"e_1_3_1_8_2","doi-asserted-by":"publisher","DOI":"10.4018\/jdcf.2013010103"},{"key":"e_1_3_1_9_2","unstructured":"N.Lewis Modification of Bayesian Updating where Continuous Parameters have Differing Relationships with New and Existing Data 2013 ArXiv Prepr. arXiv:13082791."},{"key":"e_1_3_1_10_2","unstructured":"B.Martinkauppi Face Colour Under Varying Illumination: Analysis and Applications University of Oulu Oulu 2002."},{"key":"e_1_3_1_11_2","unstructured":"Multi Conference on Computer Science and Information Systems et al.
