Open Data starts with making available the data that you already have, in whatever format.

Conceptual overview

“Open”

material (data) is open if it can be freely used, reused and redistributed by anyone

“Government data”

data and information produced or commissioned by government or government controlled entities.

Linked Open DataIntroduction in Plain English

“The Semantic Web isn't just about putting data on the web. It is about making links, so that a person or machine can explore the web of data.  With linked data, when you have some of it, you can find other, related, data” - TBL.

The Semantic Web & Linked DataOverview

5StarsOpen linked data

★★

★

★★★

★★★★

★★★★★

Make your stuff available on the Web

Make it available as structured data

Use open, standard formats (instead of excel)

Use a open data format – URLs, descriptions

Link your data to other people’s data

… Linked Data provides the means to reach the goal of the Semantic Web – “the emergence of a Web of Data”

Google’s Semantic SearchCase Studies

People should be able to ask questions and we should understand their meaning, or they should be able to talk about things at a conceptual level. ... A lot of people will turn to things like the semantic Web as a possible answer to that.“ - Google Vice President of Search Products & User Experience Marissa Mayer

21

an initiative launched on 2 June 2011 by Bing, Google and Yahoo! to "create and support a common set of schemas for structured data markup on web pages."

http://schema.org/docs/full.html

The Knowledge Graph is a collection of information sources thathelp discern a user’s specified intent with each individual query.The graph is actually an encyclopedia with structured information obtained from the web. (currently, 200 million entities)

Freebase is an open, Creative Commons licensed repository of structured data of almost 22 million entities. An entity is a single person, place, or thing connected by a graph.

Apple’s SiriCase Studies

Ask Siri how Apple recorded the best quarter in history for a tech company, and her answer

should be: "Me."

22

Siri (Speech Interpretation and Recognition Interface) is an intelligent personal assistant and knowledge navigator which works as an application for Apple's iOS.

A Brief History- In December 2007 Siri, Inc. was formed by Dag Kittlaus (CEO), Adam Cheyer (VP Engineering), and Tom Gruber (CTO/VP Design).- Siri Inc. went after funding and by November 2009 it had secured $15.5 million investment, resulted in the creation of the first Siri application, which debuted on the iPhone 3GS in February 2010.- Siri acquired by Apple; iPhone becomes the Virtual Personal Assistant

Knowledge Navigator (1987)a concept described by former Apple Computer CEO John Sculley in his 1987 book, Odyssey.

Active OntologyCase Studies

A processing formalism where distinct processing elements are arranged according to ontology notions; an execution environment.

Basic concepts * Ontology : A data structure - Formal representation for domain knowledge - Classes, attributes, relations * Active Ontology : A processing environment - Processing elements arranged according to

ontology notions - Communication channels

Conceptual overview

Data.gov, along with a number of other data-related sites of the government such as USAspending.gov and Apps.gov, are slated to be shut down due to budget cuts. The current annual budget of $37 million will be reduced to $2 million. – (Guardian April 11)

고려 사항Reality Check in Korea

데이터 민감성 : WikiLeaks vs Open Data

29

서비스 범위 : Domestic vs International

데이터 플랫폼 : 정부 vs 민간 vs 커뮤니티

데이터 내용 : 통계 /수치 데이터 vs 정보형 데이터

데이터 형식 : human-readable vs machine-readable

정부의 역할 : 시스템 구축 vs 생태계 구축 - 통제가 아닌 효율적인 서비스 지향- 데이터 공개 및 연계를 위한 로드맵 수립

- 정부기관의 데이터 소유 인식 전환 필요- 자발적인 참여와 소비를 촉진하는 전략 필요

- 데이터 범주에 따른 차별화된 공개 전략- 데이터의 활용에 따른 최적화된 서비스 모델

- 서비스 범위에 따른 구축비용 /운영 모델- 국제 표준에 기반한 데이터 접근 서비스 제공

- 통계 기반 시각화에 한정된 모델 지양- 데이터 특성에 맞는 기술 적용 모델 수립

- 지능적인 데이터 매쉬업 지원을 위한 데이터 모델링 검토

Vision of Government Open DataConceptual Architecture

“realise significant economic benefits by enabling businesses and non-profit organisations to build innovative applications and websites using public data.”

(Ding et al., 2012)

31

Roadmap of linked open government dataConceptual Architecture

“the combination of machine power and human power and deliver higher-quality data to a wide range of data consumers via visualization, mashups, and more.”

(Ding et al., 2012)

Data on the WebSummary

Data is information about things

32

Data is something machines can process

Data drives applications (e.g. web sites, mobile services)

Data is relations among things
