How I visualized the issues related to Sewol for 04.16 ~ 05.05

세월호 이슈 타임라인 from Hikmat on Vimeo.

In April 16 there was a big tragedy in Korea, the ferry named Sewol (세월호) sank just in few hours causing the death of hundreds of students.
After the tragedy, there were millions of tweets talking about sewol related issues. By analyzing these tweets we could see how people felt about sewol tragedy, how their opinions changed during the time, whom they blamed and how much they hoped for the survival of missing students.

We calculated TF-IDF values with Sewol keywords, and from those we selected the top issues related to this tragedy. We exported results to excel where the rows represented the date and time, and the columns represented the words.
I used 3ds max for visualization. It has MaxScript programming environment. I made a script to import the data from excel and draw the texts on 3D space, then animated their size by their TF-IDF value. The position of words are distributed randomly. Watch it and feel free to comment what you observed from the video.

here is the MaxScript code

Three essential things to do while building Hadoop environment

Last year I setup Hadoop environment by using Cloudera manager. (Basically I followed this video tutorial : http://www.youtube.com/watch?v=CobVqNMiqww ) I used CDH4(cloudera hadoop) that included HDFS, MapReduce, Hive, ZooKeeper HBase, Flume and other essential components. It also included YARN (MapReduce 2) but it was not stable so I used MapReduce instead. I installed CDH4 on 10 centos nodes, and I set the Flume to collect twitter data, and by using "crontab" I scheduled the indexing the twitter data in Hive. Anyways, I want to share some of my experiences and challenges that I faced. First, let me give some problem solutions that everyone must had faced while using Hadoop. 1. vm.swappiness warning on hadoop nodes It is easy to get rid of this warning by just simply running this shell command on nodes: >sysctl -w vm.swappiness=0 More details are written on cloudera's site 2. Make sure to synchronize time on all nodes (otherwise it will give error on n

NLP for Uzbek language

Natural language processing is an essential tool for text mining in data analysis field. In this post, I want to share my approach in developing stemmer for Uzbek language. Uzbek language is spoken by 27 million people around the world and there are a lot of textual materials in internet in uzbek language and it is growing. As I was doing my weekend project " FlipUz " (which is news aggregator for Uzbek news sites) I stumbled on a problem of automatic tagging news into different categories. As this requires a good NLP library, I was not able to find one for Uzbek language. That is how I got a motive to develop a stemmer for Uzbek language. In short, Stemming is an algorithm to remove meaningless suffixes at the end, thus showing the core part of the word. For example: rabbits -> rabbit. As Uzbek language is similar to Turkish, I was curious if there is stemmer for Turkish. And I found this: Turkish Stemmer with Snowball. Their key approach was to u

Solving java.lang.ClassNotFoundException problem while exporting Jar file from Eclipse

While running my compiled jar files on hadoop cluster I faced this error many times: Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.conf.Configuration Usually, I don't use maven and attach libraries manually to the project. The libraries that I use are mostly apache's libraries related to hadoop, hive, hbase and etc.. After successful compilation I export the project as a Jar file. I tried to export in many ways but I faced this ClassNotFoundException every time. So I realized that exporting my project with attached jar libraries is not the optimal solution for the problem. Then I found this solution on StackOverflow http://stackoverflow.com/questions/2096283/including-jars-in-classpath-on-commandline-javac-or-apt It describes the way how to add required (dependency) jar files while running the main jar. It is simple! You just put all jars into the same folder where your main jar file is and Run: >java -cp *:. com.kh.demo.RealtimeTFIDF Note
