Collaborative filtering method was widely used in the recommendation system. This method was able to provide recommendations to the user through the similarity values between users. However, the central issues in this method were new user issue and sparsity. This paper discusses about how to use matrix factorization and nearest-neighbour in film recommendation systems. Both of methods will be used...
One of the most interesting interdisciplinary research topics between Geographic Information Systems and Data Mining are known as Geo-demographic analysis (GDA). Among some methods in this field, Fuzzy Geographically Weighted Clustering (FGWC) is considered as the state-of-the-art for Geo-demographic segmentation. In other hand, recent studies show that its quality of clustering achievement can be...
Every region in Indonesia has different potentials and need to be analyzed for national development considerations. This analyzed can be accomplished with clustering Indonesian regional potential data, which is collected from PODES enumeration. This data consist of both numeric and categorical attributes. However, most of clustering algorithm can be applied on either numeric or categorical data. K-prototypes...
The rising of the modern Internet brought with it heap opportunities for attackers to gain illegal benefit from spreading spam mail. Spam is irrelevant or inappropriate messages sent on the Internet to a large number of recipients. Many researchers use a large number of classification method in machine learning to filter spam messages. But, there is still limited research which evaluate the use of...
With the rapid maturity of internet and web technology over the last decades, the number of Indonesian online news articles is growing rapidly on the web at a pace we never experienced before. In this paper, we introduce a combination of rule-based and machine learning approach to find the sentences that have tropical disease information in them, such as the incidence date and the number of casualty,...
Knowledge about climate change is very important in human life. The information gained can be used to learn about time period of weather season from January to December. Indonesia is a tropical country with two weather seasons, they are summer and rainy weather. Weather information and forecasting are usually reported by Indonesian Agency for Meteorology, Climatology and Geophysics, BMKG (Badan Meteorologi...
In 2010, Global Status Report on NCD World Health Organization (WHO) reported that 60 percent of deaths in the world caused by the non-communicable diseases, and one of the non-communicable diseases that consumed a lot of attention was diabetes mellitus. Diabetes is a serious threat to the health development, because diabetes is a disease that caused most other diseases (complications), such as blindness,...
Nowadays, Web becomes an important part of organization. The huge usage data as a result of interaction of users and Web can be extracted to be knowledge applied in various application. The main problem of Web usage mining are the nature of data they deal with and the handling methods. A survey on Web usage mining was conducted with Systematic Literature Review method to identify relevant studies...
Ontology is one of the semantic technology standard that can make knowledge sharing be easier. This paper reported a development of ontology that focus in pediatrie nutrition domain. This domain was chosen because it is one of the world problem. This ontology covers children's required nutrient intake and its amount. Besides that, it also covers the effect of excess and lack of nutrition. This pediatrie...
Publicly available DNA sequence database such as GenBank managed by National Center for Biotechnology Information (NCBI) is very large and still grows exponentially. The sequence data are stored in flat file format grouped in various division based on the source taxonomy. Bacterial division alone consists of more than 100 files has size about 6 Gigabytes in total. Searching in 100 files using single...
A male fertility is influenced by several factors. One of which is the quality of the sperm. Over the last 50 years, human sperm quality decreases. It became the driving force for a male to examine his sperm. It is therefore necessary to have a method to check the sperm quality which is not only accurate, but fast and cheap. Sperm quality can be measured by, one of which, sperm count. In some medical...
Multi-agent system approach is now widely used as a solution to real-world problems, including problems in the organization model. The complexity of the organizational environment demands a model of knowledge management (KM) improvement that can create innovation and responsiveness process, this matter caused by rapid changes, so the knowledge will grow and improve continuously. Multi-agent system...
Smart grid is a new breakthrough in terms of transmission and distribution power lines from power plants. All communication data transmission that occurs on the smart grid is done digitally, making it easier for operators to control and monitor every transmission data as well as monitor any equipment connected to the smart grid. However, the use of digital technologies makes the security becomes an...
This paper reviews node failure detection method in ZigBee loop network. ZigBee network was popularly used for low power and low cost implementation of wireless data transmission. Node failure detection is needed in order to maintain the network reliability. Common node failure detection methods are based on ZigBee mesh networking capability. But in many application areas which have simple loop topology,...
