I had a special lecture today for Bio-Medical Equipment Technician students today at the Institute of Engineering, Pulchowk campus. It was a good experience to explore and share Web applications in the Biomedical field. It is interesting to see that there are so many applications, resources and Open data available in the biomedical domain.
Here are my slides

Just came back from the Aid Transparency Barcamp, Kathmandu. I had a talk on Linked data and Semantic Web Technologies for Aid Transparency. It was a mixed group of audience, with both developers and non-technical people. I guess that the presentation was a bit too much for the non-technical side (sorry for that :-P).
There are many things in the slides, so sharing them here for everyone’s reference. The developers may play with the tools and datasets. Perhaps someone could use Tim’s linked data and demonstrate some interesting app. (Thanks Tim ;-))
Some major questions/concerns from the audience –
* This seems too technical, does the user need to understand all this? (No)
* What will the user see as linked data, web pages? or something different? (ya basically web pages, but driven by data from different linked sources)
But most importantly,
* What problem does linked data address? (Thanks Simon for helping me answer this .. you can put complex queries which need data from across various sources, further you can reuse/link to existing data and similarly others can reuse/link to your data)
Towards the end Simon pointed out that we still need small concrete example applications (in aid transparency) to really convince people (at different levels) to provide (linked) open data, not just demos or visualizations. Agree.
Perhaps the developers/industry can build something really useful for some stakeholder to prove the potential of linked open data.

Feel quite free after finishing the final defense for my PhD 🙂 (July 27, 2009 @ NII, Tokyo)
It went quite smoothly. Thanks to the evaluation committee for constructive comments. And it was nice to have a good number of interested audience. Thank you all for coming!
Here are the slides for my presentation, in case useful to anyone. The thesis is all about information sharing anyway 😉

I am back after presenting my paper in ASWC 2008, Bangkok, Thailand. I presented the following paper about StYLiD in the “Ontologies and tags” session.
Consolidating User-Defined Concepts with StYLiD
You can find my presentation slides here.
The conference was successful overall and an interesting experience for all. Congratulations to the organizers who made the conference a success inspite of the recent political troubles which forced the conference to be postponed to 2009, and some people could not make it to the new schedule too. It was a good conference with many high quality interesting papers. It was an enjoyable conference with various light moments and beautiful cultural shows.
It was nice to be back in Thailand again. I also visited AIT, from where I graduated, to meet some faculty and some of my colleagues who are still there. It was a great nostalgic feeling. I was lucky, I also got to attend an invited talk by Dr. Ramanathan Guha from Google, on the same day, in a full-packed room at AIT.

I am back from Karlsruhe, Germany after presenting StYLiD at the poster and demo session of ISWC 2008. My paper titled “Consolidating User-defined Concepts with StYLiD” was published in the proceedings CEUR-WS Volume 401. I have also uploaded the paper and the poster.
I prepared some screencast videos to demostrate StYLiD. I will try to post them online soon. Making screencasts proved to be a good idea as the internet connection at the venue was so intermittent 😉
It was a good opportunity for me to attend such an important conference. Prof. Martin Hepp came along and watched my demo in detail and took a picture of the entire poster – an honor for me. He also asked me specific questions and thanks for his comments. He had rightly noted that I have been referring to and citing his works like myOntology and FolksOntology 🙂
There were also other people interested in StYLiD. Luckily my stall was located next to other interesting demos like LENA (a linked data browser) and Thinkbase (a graphical interface to Freebase). However, I could not show my demo in detail to everyone, I realized that it takes time.
I will have more time to explain my work at ASWC 2008, Bangkok where I will present StYLiD as a full research paper.

Social Web Incubator Group
Good to see the Social Web incubator group charter. Great start! Harry Halpin had talked about it when he visited Tokyo and had a meeting with some W3C members here along with prof. Hideaki Takeda and I from NII. I feel that a group like this can play a very important role in identifying and addressing practical challenges that are still hindering the adoption of open semantic standards in the social web. While movements like Data portability, SIOC and FOAF have been very successful in the Semantic Web world, many issues like privacy, authentication, ownership, security, trust etc should still be addressed if such standards are to be publicly accepted. Otherwise, people feel safe and comfortable within walled data gardens while social web companies prefer to hold their customers and their data.
The mission of the Social Web Incubator Group, part of the Incubator Activity, is to explore the development of open standards for social data portability built on existing W3C standards and standards developed by the community, and to promote these solutions within the W3C.

I got an opportunity to present my paper titled “StYLiD: Structured Information Sharing with User-defined Concepts” in the annual conference of Japanese Business Model Society (Biz-model 2008) held at the university of Tokyo, October 11, 2008. Thanks to assoc. prof. Yutaka Matsuo for organizing the session on “Web technology and business models”. My presentation was special because it was the only presentation in English in the conference :-P. However, the audience seemed to be quite interested and I received some important questions, including some in Japanese that were translated to me in English 🙂
It would be interesting to explore business models or practical applications for StYLiD and receive suggestions from the business community in the future as well. It would be better to serve applications to targeted groups who are really in need rather than trying hard to motivate general people to contribute.
Here are my paper and presentation slides.

Yesterday I presented my paper titled “Information Sharing on the Social Semantic Web” in the Second NEA-JC Workshop on Current and Future Technologies. NEA-JC stands for Nepal Engineers’ Association – Japan Chapter. I made a general introduction to the social web and the Semantic Web, with the general audience from all backgrounds in mind. The paper has been written for non-technical audience. I am glad to see the interest shown by all in this area.
In general people understand what is the social web as there are many example sites many of them are actually using today. However, people find it hard to imagine what the Semantic Web is really like. There are rarely any sites that ordinary people are really using that could be used to cite examples of Semantic Web technologies. People are not satisfied by just understanding the vision and principles of the Semantic Web. People want to see the Semantic Web but its still hard to show to non-technical people.
I hope in the near future we will also have enough Semantic Web sites, just like the social or Web 2.0 sites today, so that people really see, understand and benefit from the Semantic Web. I feel that day will come soon with the social Semantic web, rather than pure Semantic Web technologies only. The social Semantic Web can be as common as the social web today if the social web community and the Semantic Web community work in cooperation.
Below are the links for the PDF and presentation slides.

MediaShift Idea Lab . Ensuring Content in User Driven Conversations
A user-driven system does not have value unless users contribute contents. It is good news that 80-20 rule is observed in this case (it is enough to have 20% of the users as active contributors and rest 80% can be passive readers). However, it is very difficult to entice this 20% users. It is not enough to have an easy-to-use interface to ensure that users will contribute – users simply don’t care. The blog post mentions some important tactics to deal with this.
It is even more difficult to entice users into contributing structured data. The associated cost is higher than that for unstructured contents. So the benefit also has to be much greater. We need more tactics for enticing users to contribute structured data.
