Enjoy it.

p.s. I hate the “huge” e-mail “rubbish” from the original DBWorld mailing list.
Thus, I have unsubcribed it, and created this rss for me, you and one who favors RSS reader.

Improve user experience

With the developping of the Internet, web search become more and more important. Meanwhile, the requirement of advanced users is also increasing. For example, the users need better user experience to support their searching task on the web. But, how can we do? It comes to a part of my research. I want to give the users better user experience when they search the web, via the current data mining techniques. Especially, we often call it web mining in the current information retrieval field.

Focusing on this topic, I did some experimental computation, analysis, implementation of our web search supporting system (ZmSearch), and concluded a research paper in the end. The title is “Using An Interactive Interface to Support Web Search for Improving User Experience“, which is to appear in the 1st IEEE International Conference on the Applications of Digital Information and Web Technologies (ICADIWT’08), this August in Czech Republic. I have to perform a presentation to introduce my contribution in the paper during the conference days from August 4 to 6. Here, firstly wish myself good luck and having a good trip.

As the future work, I have to go into the analysis of relevant keywords, and pay more attention to support the users to search the web more easily, conveniently and quickly. Of course, I still attempt to pay more efforts to help the users to find out the marginal information or knowledge more easily, and to repeat their selft-learning, and so on.

Okay, keep fighting for the better future as possible as I can.

Excelで作った図をepsへ変換

論文を書くとき、Texを使わなければならない。でも、Texで認識できる統計図や曲線図などは、epsフォーマットしかうまく使われてない。確かに、Texで書かれた文書はすごく綺麗だ。でも、それぞれの要件が制限されてしまうので、とっても面倒だ。例えば、当面の話題だと、eps図を作る方法がいくつかある。R/GNUPlot/inkscapeなどの専用ソフトでeps図がうまく作れるというのは、確実だと思う。ただ、それぞれを使うのは手間がかかる。又は、MSのExcelでまず図を作って、JPGへ変換し、更にJPGからepsへ変換しなければならない。というまずい流れがあると思っていた。流れだけ面倒ではなく、それで作ってきたEPSファイルの質量もどんどん悪くなってしまう。EPSファイルを再度Texに入れてから、最後には全然見づらいし、恐らく見えなくなる可能性も高い。

Excelで簡単に統計図を作れるため、変換されてきたepsファイルに関する質量も上がれるため、昨日論文を作成するとき、一回作り方を見直してみた。やったっっょ!下記の手順で進めば、高質量のeps図を簡単に作りになる。

  1. Excelで統計図を作成し、それに右クリックしてから、「グラフウィンド」を出す
  2. 出してきたグラフウィンドでのタイトルバーに右クリックし、PDFCreatorで印刷する
  3. 印刷から生成したpdfファイルをAdobe Acrobatで開き、名前付けで保存(Save As)
  4. それで、EPSフォーマットを選択し、変換しながら保存する

ここまで、綺麗なEPSファイルが作られた。(Bitmapからの文字化だけじゃないものよ、是非確認しよう)

このようなやり方は簡単であるだけど、R/GNUPlotなどに対して、熟練であれば、やっぱりそれぞれを使ったほうがプロだと思う。

Meebo/AjaxTrans/Project Euler

Recently, I am busy in coding for my personal research, with proposing a system named zmsearch. Of course, I want to publish it as soon as possible and provide service to everybody. But it seems no so very easy. Anyway, everything must go along its schedule, not only this single work, but also must submit 3 papers for three different purposes.

When I was trying to find out some easier methods to solve my problems, I found these interesting things as follows. Just write it down as memo.

1. Meebo

I’m sure that you should ask what Meebo is? Please read the following information reserved by official.

Meebo is a web based IM that lets you log into your IM networks from any computer with a browser and internet connection with no firewall issues. It employs technologies (like AJAX) to make it act more like a desktop application, which dramatically improves usability. Many users enjoy the benefits of a native DHTML application, as it does not consume as many system resources as a Java applet (such as ICQ2Go or Yahoo Web Messenger). Meebo also offers other services such as a chat room client and a personal IM client for your personal/corporate web pages.
Some users are also experimenting with setting meebo as their Active Desktop page to use meebo like a native Windows application for their instant-messaging purposes.

It seems very good and a very powerful aggregation for some kinds of IM tools. I like it because it seems green software, unnecessary to install any thing, only to prepare a browser and to make sure you can connect to Internet. And then keep your MSN, Yahoo!Talk, Google Talk and Meebo online at the same time.

2. AjaxTrans

AjaxTrans is an online translation tool written by Joel Parish, a seventeen-year-old boy studying at high school senior from Camarillo, California. How surprised! Its most focused feature is that AjaxTrans was developed via Ajax/javascript. Click here to try it and certainly you can click here to get more details about this supper guy! Besides, there is an online documents published by wiki

3.Project Euler

The last one is about Project Euler –

Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve. Although mathematics will help you arrive at elegant and efficient methods, the use of a computer and programming skills will be required to solve most problems.
The motivation for starting Project Euler, and its continuation, is to provide a platform for the inquiring mind to delve into unfamiliar areas and learn new concepts in a fun and recreational context.

So far as now, 172 mathematical or computer programming problems have been provided in this project. What I am thinking about this project? If I found it three years ago, maybe I could lead STU-ACM/ICPC team to much better in the ranking, and lead all our members to reach another upper grade. 画像をダウンロードするには、ここを右クリックします。プライバシー保護を促進するため、この画像はインターネットから自動的にダウンロードされません。 :) If I still had enough time, I am willing to solve all these problems in the project.

CPU cost comparison

I’m sorry for a long time no update, today I wanna give a figure and point out the surprise of CPU cost comparison between addition and multiplication under modern CPU chip. Even though it’s a fact, I still cannot trust it, just because the integer’s addition computation has became as fast as multiplication. In other words, with the development on hardware integration and CPU chip manufacture, addition computation hasn’t any advantage comparing with multiplication so far as now. According to our researchful requirement, I figured out this comparison in the following figure.

What do you think about this surprised result? Please leave your comments, thanks. Maybe your good advices will help our research toward well progressing.
