			Data Mining for Political Scientists
			By: AJDA, Nov 30, 2016

	~~Data Mining for Political Scientists~~
	~~By: AJDA, Nov 30, 2016~~

	Being a political scientist, I did not even hear about data mining before I’ve joined Biolab. And naturally, as with all good things, data mining started to grow on me. Give me some data, connect a bunch of widgets and see the magic happen!

	But hold on! There are still many social scientists out there who haven’t yet heard about the wonderful world of data mining, text mining and machine learning. So I’ve made it my mission to spread the word. And that was the spirit that led me back to my former university - School of Political Sciences, University of Bologna.

	University of Bologna is the oldest university in the world and has one of the best departments for political sciences in Europe. I held a lecture Digital Research - Data Mining for Political Scientists for MIREES students, who are specializing in research and studies in Central and Eastern Europe.

	~~Lecture at University of Bologna~~

	~~The main goal of the lecture was to lay out the possibilities that contemporary technology offers to researchers and to showcase a few simple~~ text mining ~~tasks in~~ Orange. ~~We analysed Trump’s and Clinton’s~~ Twitter ~~timeline and discovered that their tweets are highly distinct from one another and that you can easily find significant words they’re using in their tweets~~. ~~Moreover~~, ~~we’ve discovered that~~ Trump ~~is much better at social~~ media ~~than~~ Clinton, ~~creating highly likable and shareable content and inventing his own hashtags~~. ~~Could that be a tell-tale sign of his recent victory~~?		Tujuan utama adalah untuk menjabarkan kemungkinan yang ditawarkan teknologi kontemporer kepada para peneliti dan menunjukkan beberapa tugas text mining sederhana di Orange. Kita menganalisa time line Trump dan Clinton di Twitter dan menemukan bahwa tweet mereka sangat berbeda satu sama lain dan kita dapat dengan mudah menemukan kata-kata penting yang mereka gunakan di tweet mereka. Selain itu, kita telah menemukan bahwa Trump jauh lebih baik di media sosial daripada Clinton, menciptakan konten yang sangat disukai dan dibagikan dan menciptakan tagar sendiri. Mungkinkah itu pertanda dari kemenangan Trump?

	~~Perhaps~~. ~~Our future,~~ data-mining ~~savvy political scientists will decide~~. ~~Below~~, ~~you can see some examples of the workflows presented at the~~ workshop.		Mungkin. Ilmuwan politik yang tidak gaptek data-mining akan menentukan masa depan kita. Di bawah ini, kita dapat melihat beberapa contoh workflow yang disajikan di workshop.

	~~Author predictions from~~ Tweet ~~content~~. ~~Logistic Regression reports on~~ 92% ~~classification accuracy and~~ AUC ~~score~~.

Regresi Logistik melaporkan akurasi klasifikasi 92% dan skor AUC. Confusion Matrix dapat menampilkan tweet yang tidak diklasifikasikan untuk Corpus Viewer, tempat kita dapat memeriksa tweet ini lebih lanjut.

	Word Cloud ~~from preprocessed tweets~~. ~~We removed stopwords and punctuation to find frequencies for meaningful words only~~.		Word Cloud dari tweet yang telah di preproses. Kita menghapus stopword (biasanya kata penhubung) dan tanda baca untuk menemukan frekuensi hanya untuk kata-kata yang bermakna.

Word Enrichment oleh Penulis. Pertama-tama kita menemukan tweet Trump dengan Select Rows dan kemudian membandingkannya dengan seluruh corpus di Word Enrichment. Widget mengeluarkan daftar peringkat kata-kata penting untuk subset yang disediakan. Kita melakukan hal yang sama untuk tweet Hillary.
