15 (and counting) Ways to Explore ISWC 2010 Data

This year at ISWC, when we worked on the metadata, we have a Data Consuming task force to develop tools that can browse/visualize the data many different ways, e.g., faceted browser, filter browser and mobile browser.

As soon as we have the basic dataset published, we immediately get feedback from people on off-the-shelf tools that can work with the data. The list is quickly growing. I collected the screen shots of some working instances (including tools the metadata committee has built) in a slides. I have no doubt that the number “15″ will be changed when the main conference begins …. in 2.5 hours! So expect some updates very quick.

P.S. 今天 Semantic MediaWiki 1.7.0 发布。

用语义维基来写应用

摘要:语义网应用适合于那种数据不断动态变化的情况。另外一个特点,就是它可以打破应用间的界限,打破服务间的界限。用语义维基(Semantic Wiki)做应用的一些例子,本身谈不上什么价值,只是这种思路,我觉得以后可能会有用。

注:关于语义维基基础,参《一个Semantic Media Wiki简短教程》(2009-07-21)

今天和人聊到语义网应用的一些特点,我举了用语义维基(Semantic Wiki)做应用的一些例子。下面引用的,大部分来自我以前的一篇文章:

维基中不可承受之轻

The Unbearable Lightness of Wiking

这是我2010年5月在Spring SMW Conference 2010 (MIT)上的一个幻灯片。总结了KAHT项目(由DARPA支持)关于语义维基(Semantic Wiki)可用性的一个实验的结果。我们发现,普通用户的语义建模能力,很难产生有意义的语义数据。这不仅是系统本身(Semantic MediaWiki)的问题,更深刻的,是人的认知能力的问题。很多在知识表现学者想当然的问题,在“普通人”,会有完全不同的,“千奇百怪”的想法。

Towards Webtop [2008]

http://tw.rpi.edu/wiki/Blog:Baojie/Item-50

http://tw.rpi.edu/weblog/2008/07/25/towards-webtop/

2008-07-25

Some of our Tetherless World researchers including me have just written a short paper to sell the idea of constructing a “webtop” using semantic technologies. In short, a webtop is a desktop on the web, that does similar jobs such as managing files, doing word processing, managing contacts, scheduling tasks, emailing, etc. Please see some examples of webtops with pretty GUIs.

Almost one decade ago, there has been hot for a while for the concept of “network computer”. At that time, a network computer means some low-end computer with limited storage and computational capacity that relying on the network to get great power. The webtop idea reminds me of network computer as they, while are different in many aspects, share the same idea of powering users with networked infrastructure. Ten years ago, this vision was tested with physical computers but largely failed, while today, with the advance of technologies, is revived by allowing users to create virtual computers that only exist on the websphere. I have many reasons to believe this time it will not only survive, but also prevail.

语义网与推荐(3)推荐系统基础

Recommender Systems http://www.slideshare.net/T212/recommender-systems-1311490 【非常基础】

资源:DL-Learner

一些关于从ABox学习TBox的资源。

目的:语义压缩。所有的Machine Learning,在本质上都是压缩算法。

DL-Learner: http://dl-learner.org/Projects/DLLearner/OnePageIntroduction

Jens Lehmann:http://jens-lehmann.org [publications]

略读了一下,感觉不是很有说服力(convincing)。对所谓Re nement Operator,觉得没有什么特别的。由于这本质是一个搜索问题,文中却没有什么讨论搜索策略。没有和统计方法和信息论结合,我觉得是很大的弱点。

Expressive Query Answering For  Semantic Wikis

May 11th, 2001 at Cambridge Semantic Web Meetup

#1 Welcome

#2 Semantic Wiki as a Data Store

Semantic wikis have been increasingly popular in the past a few years. Their popularity may be attributed to many features of “wikiness”, such as being collaborative, simple, easy to learn, informality-tolerate, and evolving-capable. A semantic wiki allows you to start from unstructured, raw data, and gradually adding structures or even semantics to the data by yourself or by others. This approach often works better than many other knowledge management approaches for non-expert users.

为什么Context很重要

最近两个消息都说明了Context(背景,环境,域)的重要性

TriQuint是我很关注的一个股票。一个新闻说:TriQuint’s quarterly revenue falls 11% to $224.3m

这看起来是个坏消息。但是,如果你对半导体行业熟悉,你会发现几乎所有的公司第一季度的收入都会比上年第四季度低,TriQuint也不例外。你把这个下降本身放在历史数据这个context下看,再正常不过,无非是圣诞旺销季后的季节性变化而已。

RDF的语义

2008-09-04

这个讲义是基于RDF的官方语义(Hayes,2004)【题外话,这个Hayes是个老顽童】

更多资料看: http://tw.rpi.edu/wiki/index.php/RDF_and_OWL_Semantics

[slideshare id=4661990&doc=2008-09-04rdfsemantics-100701160820-phpapp02]

【我一直有想法把RDF,OWL和RIF的语法,语义串起来整理一遍。网上系统的中文资料好像还没有。英文的有一本Foundations of Semantic Web Technologies,最好。不过我觉得因为作者是逻辑学家,还是有点难。如果能有一个更深入浅出的讲义,最好。】

总结我为ISWC 2010做元数据负责人(metadata chair)的经验,兼RuleML 2011元数据展望。一直想做这事,一直懒。主要是为我自己查找方便,可能比较天马行空。因为很多原始资料是英文的,所以抱歉就不翻译了。

RDF and Context (域)

昨天决定把Context翻译成域。今天接着说说用RDF来表示Context,主要是帮我自己理清思路。

去年做了一点这个方向的工作,参加了RDF Next Step Workshop。这是幻灯片:

语义网:走向下一代杀手级应用
