Facing Tough Work
Written by Tenjitsu   
Tuesday, 19 February 2008

Long time, I have no chance to write interesting stories since this semester is so tough for me. I have gone to China Town and made a small trip last week, but still have no chance to write about it. And, this blog is not about my trip as well. Actually, this blog is about my workload here.

I took three courses in this semester and also work at ISI as a programmer for 8 hours a week. Here is my Todo list for every week. For the first course – Information Integration on Web – I have to read 2 - 4 papers; learn a new web integration tool and do homework; as well as review 2 – 4 papers for quiz every week. Normally, it takes one day per week to read papers and another day to finish homework and review quiz. That is only one course.

Another course is Analysis of Algorithm. Even though it is somewhat similar to my undergraduate course, I have to spend a lot of time finishing its homework every week. I have to design an algorithm to solve homework’s question, prove it, and analyze its complexity. And, it usually takes half day to finish homework and almost one day to read algorithm textbook.
The last course is somewhat painless since there are three assignments and one project (while others have homework every week). However, I have to spend a lot of time learning C++ because of the assignments. And, C++ is complicated for me.

I also spend all Wednesday working at ISI. Currently, I am maintaining a PHPBB, which is an open source web board. It is not so tough, but it takes time as well. Moreover, I have to spend time doing companies research and applying for a summer intern too.
Thus, this semester is so rough. I have to say that I am so tried, but hope that it will be passed as good as possible.
 

The Semantic Web
Written by Tenjitsu

Nowadays, the World Wide Web becomes much more dominant from the one in five years ago since it allows individual to be a publisher and express his or her own idea. Before this era, the WWW used to belong to large organizations or companies as well as its contents are very limited to texts and images. Then, the growing of internet technology, especially the uploading bandwidth, lets everyone easier publish their stories, images, or even videos to the world, as we can see from the exponential growth of many web sites namely MySpace.com, Youtube.com, or Flickr.com. However, from many experts’ view, we only utilize about 25% of its power.

The Semantic Web is intended to be the future of the WWW in order to utilize its all potential. This concept was initiated by Tim Berners-Lee – the investor of the World Wide Web – and others. In their vision, the characteristic of today WWW contains one major problem which is WWW is designed for human to read. At the first glance, the previous statement should not be a problem since WWW is obviously designed for human. However, when the WWW is growing to tremendous size, it is tough for us as a human to read all information in the Internet. We therefore need the help of computer to read that information and retrieve only handful interesting ones for us. Thus, the WWW should not be readable only by human but also by computer software. Web sites will then become tremendous valuable resources that we can write infinite software utilizing them.

For example, if I would like to make an appointment with a physician, I can search his information on the Internet, call his front desk, and ask for available times. What if his available times are not match with mine? Then, I have to repeat this tedious process again with a new physician. In the future, with The Semantic Web, however, each physician will have his/her own identity in the WWW. Then, I can use software (called Agent) to search for information (since this information is in machine-readable format). The Agent also know my schedule and then can find the best match as well as make an appointment for me. This example is a very simple application which we will gain from The Semantic Web.
The WWW is a very young technology and it needs us to shape its future. Presently, there is no one know what it will become in the future. But, a lot of people, especially researchers, try to gradually develop it to benefit humanity most. What do you think about the WWW in the future? Which feature of it will benefit you most?
