One of the diseases anticipated by doctors is hepatitis. This is because if the patient is not detected from the beginning having hepatitis, then the disease will develop into liver cancer. It can be seen that cancer is one of the deadliest diseases in the world that there are no drugs used for healing. By utilizing this increasingly developing science, researchers try to predict or classify whether a patient has suffered from hepatitis sickness based on the results of tests that have been undertaken before. One data mining technique can be used to predict Hepatitis and the method used is Naive Bayes.
The Brimob Corps is a special police force, just like the special military detachments held by the TNI such as Paskhas and so on. At present brigade corps police national is busy being discussed in the real world and cyberspace, especially on social media twitter. Many opinions about the brigade corps police national so there are positive and negative opinions. Social media twitter is now one places to spread information about brigade corps police national. This study cases uses text mining techniques with support vector machine (SVM) method which aims to classify public sentiments towards brigade corps police national on twitter. The dataset used is tweet in Indonesian with keyword “Brimob” with a total dataset of 1000 tweets. Text mining, transform, tokenize, stemming, and classification, etc. techniques are useful for building classification and analysis of sentiment. RapidMiner and Gataframework are also used to help create sentiment analysis to measure classification values. Accuracy values obtained with support vector machine (SVM) approach 86,96%, with precision values of 86,96%, and recall values of 86,96%.
Paten merupakan salah satu bagian dari Hak Kekayaan Intelektual (HKI). Dan dengan semakin banyaknya paten yang mendaftar dari berbagai negara dari tahun ke tahun, membuat peluang untuk dapat diprediksi pendaftarannya pada tahun berikutnya. Prediksi merupakan dugaan atau prediksi mengenai terjadinya suatu kejadian atau peristiwa di waktu yang akan datang. Prediksi bisa bersifat kualitatif (tidak berbentuk angka) maupun kuantitatif (berbentuk angka). Analisis regresi adalah suatu metode statistik yang mengamati hubungan antara variabel terikat Y dan serangkaian variabel bebas X1,…,Xp. Tujuan dari metode ini adalah untuk memprediksi nilai Y untuk nilai X yang diberikan. penelitian ini di dapatkan bahwa metode linear regresi layak dan efektif untuk memprediksi pendaftaran paten untuk tahun selanjutnya berdasarkan data pendaftaran dari tahun 2014 sampai tahun 2018.
Text mining can be used to classify opinions about complaints or not complaints experienced by XL customers. This study aims to find and compare classifications in the sentiments of analysis from the view of XL customers. This dataset was derived from tweets of XL customers written on myXLCare Twitter account. In text mining techniques, “transform case”, “tokenize”, “token filters by length”, “n-gram”, “stemming” were used to build classification and sentiments of analysis. Gataframework tools were used to help during preprocessing and cleansing processes. RapidMiner is used to help create the sentiment of analysis to search and compare two different classifications methods between datasets using the Naïve Bayes algorithm only and Naïve Bayes algorithm with Synthetic Minority Over-sampling Technique (SMOTE). The results of the two methods in this study found that the highest results were using the Naïve Bayes algorithm with Synthetic Minority Over-sampling Technique (SMOTE) with an accuracy of 86.33%, precision 82.85%, and recall ratio 92.38%.
The large number of merchants that make sponsorship held by the Bank reaches thousands, data mining is used to classifying thousands of data. Naïve Bayes algorithm and C 4.5 are classification algorithms in data mining. The classification results are used as determinant where the merchant deserves to receive the sponsorship program, which potentially provides the source of funds and increase the brand awareness of the company by looking at the performance, transaction amount, total nominal, average daily transaction, average transaction nominal. Comparison results show that The C 4.5 algorithm is the best model for handling case of Merchant eligibility in the Sponsorship Program. This can be proved by looking at the level of accuracy generated on the testing and validation process of the model. Both models have the same AUC value but the C 4.5 algorithm produces a superior accuracy value with a difference of 0.45% compared to Naïve Bayes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
