Many people are still confused to determine the theme of the article appropriate to the article they have. For that reason, we need a document classification algorithm that can group the articles automatically and accurately. Many classification algorithms can be used. The algorithm used in this study is naive bayes and the k-nearest neighbor algorithm is used as the baseline. The naive bayes algorithm was chosen because it can produce maximum accuracy with little training data. While the k-nearest neighbor algorithm was chosen because the algorithm is robust against data noise. The performance of the two algorithms will be compared, so it can be seen which algorithm is better in classifying documents. The comes about obtained show that the naive bayes algorithm has way better execution with an accuracy rate of 88%, while the k-nearest neighbor algorithm has a fairly low accuracy rate of 60%.</span></span>

<p>Diabetes is a major concern all over the world. It is increasing at a fast pace. People can avoid diabetes at an early stage without any test. The goal of this paper is to predict the probability of whether the person has a risk of diabetes or not at an early stage. This would lead to having a great impact on their quality of human life. The datasets are Pima Indians diabetes and Cleveland coronary illness and consist of 768 records. Though there are a number of solutions available for information extraction from a huge datasets and to predict the possibility of having diabetes, but the accuracy of their mining process is far from accurate. For achieving highest accuracy, the issue of zero probability which is generally faced by naïve bayes analysis needs to be addressed suitably. The proposed framework RB-Bayes aims to extract the required information with high accuracy that could survive the problem of zero probability and also configure accuracy with other methods like Support Vector Machine, Naive Bayes, and K Nearest Neighbor. We calculated mean to handle missing data and calculated probability for yes (positive) and no (negative). The highest value between yes and no decide the value for the tuple. It is mostly used in text classification. The outcomes on Pima Indian diabetes dataset demonstrate that the proposed methodology enhances the precision as a contrast with other regulated procedures. The accuracy of the proposed methodology large dataset is 72.9%.</p>

Penggunaan forum sebagai sarana pembelajaran telah banyak digunakan pada kalangan Mahasiswa. Forum digunakan sebagai sarana berdiskusi antar sesama anggota forum untuk membahas materi sesuai dengan judul topik. Judul topik biasanya ditentukan sesuai dengan isi materi yang akan dibahas. Judul topik yang sudah terlalu banyak di dalam sebuah forum dapat berakibat salah dalam pemilihan judul. Salah satu cara untuk mengatasinya yaitu dengan melakukan klasifikasi judul topik secara otomatis sesuai dengan isi materi. Klasifikasi teks dapat diselesaikan dengan menggunakan teknik text mining. Pada proses klasifikasi yang dilakukan yaitu dengan membagi dataset menjadi 2 (dua) bagian menjadi data latih (training) dan data uji (testing). Pada tahapan awal klasifikasi dilakukan proses pre-processing yang diawali dengan tahapan tokenisasi, kemudian dilanjutkan dengan filtering dan diakhiri dengan stemming. Ada beberapa metode yang dapat digunakan dalam klasifikasi teks antara lain naïve bayes classifier (nbc), k-nearest neighbor (k-nn), rocchio, weight adjusted k-nearest neighbor (wa k-nn) dan lain-lain. Pada penelitian ini, penulis membandingkan 2 (dua) metode yaitu nbc dan k-nn. Dari hasil perbandingan kedua metode dapat disimpulkan bahwa metode k-nn lebih baik tingkat akurasinya daripada metode nbc. Hal ini dibuktikan dengan tingkat akurasi sebesar 80% untuk metode k-nn dan sebesar 73% untuk nbc yang dihitung dengan menggunakan metode confusion matrix.
