Pos Tagging

Analisis sentimen atau opinion mining dapat digunakan untuk mengekstrak opini dari baris baris teks menjadi suatu informasi. Salah satu metode yang digunakan adalah Hidden Markov Model (HMM). HMM digunakan untuk memberikan kelas kata secara gramatikal pada suatu kalimat. Setelah kelas kata dapat ditentukan selanjutnya menentukan aturan dengan menggunakan rule based. Dengan menggunakan rule based suatu kalimat dapat ditentukan termasuk opini atau bukan. Penerapan metode Support Vector Machine digunakan untuk mengklasifikasikan opini ke dalam opini positif dan negatif. Data yang digunakan adalah data pada penangan keluhan dan pada opini online pada Unit Pelayanan Teknis Jaminan Kesehatan Bali Mandara Provinsi Bali. Hasil proses opinion mining akan diuji menggunakan metode precission, recall dan akurasi. Hasil penelitian menunjukkan presentase nilai precission, recall dan akurasi memiliki rata rata presentase sebesar 89 persen. Ini menunjukkan metode pos tagging dan SVM mampu mengklasifikasikan kalimat kedalam opini dan menentukan kalimat ke dalam opini positif dan negatifDOI: 10.24843/MITE.1601.13

Daily Lives

We propose a human behavior detect method based on our development system of multifunctional outlet. This is a low-power sensor network system that can recognize human behavior without any wearable devices. In order to detect human regular daily behaviors, we setup various sensors in rooms and use them to record daily lives. In this paper we present a monitoring method of unusual behaviors, and it also can be used for healthcare and so on. We use Hidden Markov Model(HMM), and set two series HMM input to recognize irregular movement from daily lives, One is time sequential sensor data blocks whose sensor values are binarized and splitted by its response. And the other is time sequential labels using Support Vector Machine (SVM). In experiments, our developed sensor network system logged 34days data. HMM learns data of the first 34days that include only usual daily behaviors as training data, and then evaluates the last 8 days that include unusual behaviors. Index Terms—multifunctional outlet system; behavior detection; hidden markov model; sensor network; support vector machine.

Speech Tagging

The research conduct a Part of Speech Tagging (POS-tagging) for text in Indonesian language, supporting another process in digitising natural language e.g. Indonesian language text parsing. POS-tagging is an automated process of labelling word classes for certain word in sentences (Jurafsky and Martin, 2000). The escalated issue is how to acquire an accurate word class labelling in sentence domain. The author would like to propose a method which combine Hidden Markov Model and Rule Based method. The expected outcome in this research is a better accurary in word class labelling, resulted by only using Hidden Markov Model. The labelling results –from Hidden Markov Model– are  refined by validating with certain rule, composed by the used corpus automatically. From the conducted research through some POST document, using Hidden Markov Model, produced 100% as the highest accurary for identical text within corpus. For different text within the referenced corpus, used words subjected in corpus, produced 92,2% for the highest accurary.
