Research Activities on Semantic Web Technology in Japan

Semantic Web Committee 2001- It aims to survey trends on Semantic Web Technologies and

promote broad uses of them. It organizes annual (Japanese) Semantic Web Conferences

which show the latest trends of SW technologies every year. In 2011 and 2012, the theme of the conference focused on

LOD. Its members are mainly industrial people.

Special Interested Group on Semantic Web and Ontology (SIG-SWO) in JSAI (the Japanese Society for Artificial Intelligence) 2002-

It organizes domestic workshops 2 or 3 a year. (Total:27) The state of recent workshops:

Presentations: 7-10 Participants: 30-60 (Academic : Industrial = 7 : 3 )

Linked Open Data Challenge Japan http://lod.sfc.keio.ac.jp/challenge2011/ http://lod.sfc.keio.ac.jp/challenge2012/

Backgrounds and Motivationsfor Linked Data Challenge Japan

2006- Linked (Open) Data Activity were started and becoming very active in

Western countries. e.g. DBPedia was presented at ISWC2007 and WWW2007

2009-2010 Trend repot about Linked Data Activity in overseas as by Semantic

Web Committee (of Japan). The committee members were aware of the need to catch

up the activity in Japan. 2011 Mar.

The first announcement about Linked Open Data Challenge Japan 2011 and recruitment of Executive Committee members in (Japanese) Semantic Web Conference 2011.

2011 June The first Executive Committee Meeting.

2011 Oct. The submission site was opened!

2012 Mar. The awards ceremony for Linked Open Data Challenge Japan 2011.2012/08/16 IASLOD 2012 9

Goal and Methods Goal

To promote Linked Open Data, that is, publishing open data and linking them across domains.

As the multiplier effect of them, to create new valuable technologies and services.

Methods – Sub goals Organizing a contest as an opportunity in which people who

work on LOD can present their activities and results. Designing of schema (Rules) for the LOD Challenge.

To provide technical information about LOD. Making and publishing materials about basic techniques of LOD.

Cultivating new communities of people from a variety of different fields to work on.

Organizing events/seminars named LOD Challenge Day.

Linking Data, Linking People

Problems No project

We had to recruit committee members. All members are volunteers.

No Founding We had to find sponsors.

No Data We had no published open data participant can use.

Cf. Open Data Challenge in EU, Challenge.gov in US.

No (explicit) community We were very concerned about how many

submissions we could have. What we have…

High ambition that we have to do it NOW!2012/08/16 IASLOD 2012 11

Differences between LOD Challenge Japan and other LOD contests appears in differences of the datasets.

We can see which domains are advanced in LOD, which datasets are required now, etc.

It reflects the “NOW” of Japan every years. This is one of meaningful reason to continue the LOD

News on LOD in JapanJapanese Public Open Data

2012.7. 4 IT Strategic Headquarters in Japan published “e-

government open data strategies” . Basic principles

① The governments themselves publish public data positively. ② Publish data in machine readable formats. ③ Promote to use for no matter commercial or not ④ Quickly start to open data form public ones. And the results

step by step.

2012. 7. 27 Open Data Promotion Consortium was established.

CKAN in Japanese was stated. http://data.linkedopendata.jp/

2012/08/16 IASLOD 2012 34

Towards Japanese LOD Foundations Some of the submitted applications aim to provide

basic technologies independent of domains. Kinds of basic technologies which they provide.

Developing LOD (3) Convert Table data / bibTex to RDF.

Searching and Visualizing LOD (4) Finding link between resources in different LOD.

They could be foundations for Japanese LOD.

Summary What we did

Total 73 submissions by 84 persons/groups. There are many high quality submissions.

It was very successful! The participants could be a LOD community in

Japan. We could one of our purposes.

What we learn Linking people is very important for linking data.

Future works Linking between submissions. (There is a few example in

2011) Creating LOD communities in Local (not Tokyo) areas. Increasing participants from other domains (including general

computer sciences) and ordinary people (non-experts).2012/08/16 IASLOD 2012 37

Future plans Future plans

Linked Open Data Challenge Japan 2012

Committee member are working very actively! New track: Visualization track. New sponsors and data provide partners will be

confirmed. Now, we can use datasets and ideas submitted in

2011!

Planed events LOD Challenge Day in Tokyo and Nagoya. Open data Hackathon in Sabae. Joint event with JIST 2012, Nara.

LOD Challenge Asia? We need your help!
