每天走在地铁里，都能看到很漂亮的海报。海报上的小哈利（芬特，好像也是yu cheng qing&yi nengjing的儿子的名字）终于不再幼齿，逐渐长大；有点美少年的意思了。我对这一点很满意。于是也有了要去看看的想法。
就是这么一个长相平凡（甚至lower than everage）的男人，不用抬手，甚至看都不用看你一眼，就可以对你下了蛊。
嗯。刚刚去baidu 了一下（再次点名表扬一下自己的品味。hoho），据说是影片暴力镜头太过云云。也许我看到的是剪过的版本。我看到的暴力的场景，一律选择了非常合适的音乐（对不起，词汇贫乏，只会用非常合适），演员的动作的节奏和画面的节奏都处理得非常好。在看的时候，第一次想到暴力的美学几个字。个人觉得比sin city好！sincity用了黑白两色，比较容易有冲击感，但是深入人心就不足。
Brief Content of the Interview
Here is the interview to TimBerners-lee by Andrew Updegrove.
The topics include:
"Questions and Answers: Our interview was intended to help those that do not yet have the Semantic Web in focus gain an understanding of what the Semantic Web will (and will not) be, what we can look forward to using it for, and how it is likely to become real. Our questions were divided into the following six categories:
- Vision: Why build a Semantic Web now, rather than add other capabilities at this point in time, and what new capabilities will the Semantic Web have?
- Status: Who is already committed to create the Semantic Web, and how do we get the rest on board?
- Critics: What has worked well and what has not proceeded so smoothly in developing Semantic Web standards, and what are the things that critics don’t “get” about the Semantic Web?
- Business Reality: What are the biggest challenges to bringing the Semantic Web into being?
- Infrastructure: Will other standards be needed in the future to take full advantage of the Semantic Web, and who will develop them?
- Users: What will it be like to use the Semantic Web?
1.in the Semantic Web, it is not necessary for every page having a corresponding metadata(encoding in RDF/OWL). That is, we have pages for people only; have metadata for machines only (of course people can read /use directly), and have pages plus their metadata.
2.In the recent years, W3C has contributed mostly in providing an infrastructure on how to describe knowledge by machine in distributed environments. not on how to create metadata. It is like to define the TCP/IP protocol stack instead to build applications based on TCP/IP
"CSB: What are the limitations of the Semantic Web – what will it enable someone to do, and what will it not permit us to do?
TBL: The goal of the Semantic Web initiative is to create a universal medium for the exchange of data where data can be shared and processed by automated tools as well as by people. The Semantic Web is designed to smoothly interconnect personal information management, enterprise application integration, and the global sharing of commercial, scientific and cultural data. We are talking about data here, not human documents.
The Semantic Web is not about the meaning of English documents. It’s not about marking up existing HTML documents to let a computer understand what they say. It’s not about the artificial intelligence areas of machine learning or natural language understanding -- they use the word semantics with a different meaning.
It is about the data which currently is in relational databases, XML documents, spreadsheets, and proprietary format data files, and all of which would be useful to have access to as one huge database.
Still No Killer App?
When asked on the Killer app of SW, we response by: SW itself is a killer app. But it's not a good answer of course.
In fact, it is hard for us to find a good application. Why?
1. if we set the scenario to be the interoperation among several enterprise, we lose the feature of distribution, which is the most significant different of SW/RDF/OW to the XML.
2.if we try to find a scenario benefits the entire web. Intuitively we will start off by finding the usefulness of the SW to the ordinary people, which, almost immediately equals to, to make use of metadata connected with web pages.
Many researchers work on this point now. But the results are not so inspiring. I think it is because the problem is complicated and far from be used widely. (Think I will look into it later ).
Fortunately, the work from web2.0 will help.
The most important of all is , I think, the SW is mainly about the machines, not about the connection of webpage to metadata. So SW will not make the connecting work more easier, excepting we have a language for metadata/knowledge(of course it is important). On the contrary, it is the connecting will made the SW more convictive.

Finally, I am here talking about folksonomy, ontology and tagging again,because the topic I am ready to explore turned out to have be published in an European conference in Dec, 2005.
The professor I worked with said it is a striking info for us......The idea, the experiment and the method are all quite similar to what we are going to do.
The lesson is, you should be quick!
Here you can find the paper, if interested in.
After paining and moaning to my friends for several days. Finally I calm down and think over them again. And here comes the initial work.
Many discussions arised on Folksonomy and Semantic Web,
Folktologies -- Beyond the Folksonomy vs. Ontology Distinction ;
http://ecolab.ruc.edu.cn/blog/zhangsr.php?itemid=132 (In Chinese);
among which the statements from wikipedia inteste me the most.
Take tagging, the possibly most popular form of folksonomy , as an example. The wide spreading and growth of tagging proved, instead of debased, the fundamental idea of semantic web: add machine readable metadata will make a better web for human being.
Thus, the most valuable part of folksonomy lies in its guiding us the way to add metadata to the web (Regrettebly, the machine is far from satisfaction on this task.)
Tagging is just an start point. By tagging, we get "metadata soup".
What's the next? It is what google base done. Google base involved people in, create metadata and knowledge!

A website that explains RDF and its functions to the outsided world.
As the author, Joshua Tauberer, said:
" The problem I was trying to fix is that, as
far as I've seen, we need to do a much better job of explaining to the outside world just why RDF is so simple and useful. We're not going to
reach a Semantic Web any time soon unless more people know about and understand RDF. "
The article "Quick Intro to RDF" is so well written. Clear and hitting the point. I would like to recommend all the beginners of SW and RDF to this article.
- "RDF isn't strictly an XML format, it's not just about metadata, it has little to do with RSS, and it's not as complicated as you think."
- "RDF is a method designed for expressing knowledge in a decentralized world and is the foundation of the Semantic Web, in which computer applications make use of distributed, structured information spread throughout the Web."
- "Everything at all mentioned in RDF means something, whether a reference to something concrete in the world, an abstract concept, or a fact. Standards built on RDF describe logical inferences between facts and how to search for facts in a large database of RDF knowledge"
- "RDF applications can put together RDF files posted by different people around the Internet and easily learn from them new things that no single document asserted. It does this in two ways, first by linking documents together by the common vocabularies they use, and second by allowing any document to use any vocabulary"

Can`t input chinese because I am working on an apple with only english and japanese input method.
It`s a desk top apple. of course it is cool. but I am not familiar with it till now. The keyboard is a littel bit small (expecially it is in japanese layout) and the UI is not familiar. O.K. O.K. anyway, I am old and out. I will choose working on MS windows till there are reasons other than fashion or in or evil MS. @¥@
I write three letters during my weekend, now I feel relief and comfortable.
Wanghao has mentioned that Floyd has a theory that one will be happy and peaceful if and only if he gets well with( in chinese we use the word: gao3ding4.) the most closet 10 peoples around him. I agreed with him, and again, this theory is proved true now.
Recently there is a theory with the name "6-dimension space". In short it argues that u can get to know anyone along a path with at most 6 people. But why I bother to know the people has nothing to do with me. Suppose I can get to know Bush in this way, can I persuade him stopping the war? redicuios. en.. maybe I am the people labed by inactive. ok, I am lazy and feel enough with no more than 20 people around me.
1st letter to Del.icio.us. explain my experiments to the staff. and just to see if they are mercy enough as to permitting my usage of their data. And till now I just get the confirmation letter but not the response. So I started my programe again, this time with only one thread. This thread has been survived for 20 hours at the time I left my dorm. My heart bleeding, because the frequent I/O made my hard disk noise....
2nd letter to prof Xu. My advisor in Peking Univ. Haven`t contact with him for a long time.
3rd letter is finished at about 2:00am this morning. To my advisor here in tokyo univ. Because I am trapped by myself. That is I am so eager to working on my previous topic, but prof. assigned me a new one. I am not opposit to it, just I need time and concentrate. One time one job. :D (In fact, professor has talked with me after the mail. He is so kind ^_^ and now I felt relief. need not worrying and wanderring, and go on with my resesarch. hoho)
So the world is so beautiful today~~ lalalala...

今天碰到实验室的前成员，我们update自己的最近情况，我说我写了一个crawler抓del.icio.us的数据。will说：you write a crawler YOURSELF？迷笛说：That's not SO difficult。中华人民共和国北京大学计算机系毕业的女学生也是计算机系毕业的学生好不好。
