Web of Data

Membangun Web of Data

Tim-Barness Lee:

oOne star - make your stuff available on the Web

(whatever format)

oTwo stars - make it available as structured data (e.g.

Excel instead of image scan of a table)

oThree stars - non-proprietary format (e.g. CSV instead

of Excel)

oFour stars - use URLs to identify things, so that people

can point at your stuff

oFive stars - link your data to other people's data to

provide context

Semantic Search

Semantic search seeks to improve search accuracy by understanding searcher’s

intent and the contextual meaning of terms as they appear in the searchable

dataspace, whether on the Web or within a closed system, to generate more

relevant results (wikipedia)

Tools that usually work without the necessity of a local browser. It is a

subcategory of “Special Browser”. They retrieve the data on the Web directly,

dereferencing the URIs.

Open Data

Open data is data that can be freely used, reused and redistributed by anyone -

subject only, at most, to the requirement to attribute and sharealike.

Availability and Access: the data must be available as a whole and at no more than a

reasonable reproduction cost, preferably by downloading over the internet. The data

must also be available in a convenient and modifiable form.

Reuse and Redistribution: the data must be provided under terms that permit reuse

and redistribution including the intermixing with other datasets.

Universal Participation: everyone must be able to use, reuse and redistribute - there

should be no discrimination against fields of endeavour or against persons or groups.

For example, ‘non-commercial’ restrictions that would prevent ‘commercial’ use, or

restrictions of use for certain purposes (e.g. only in education), are not allowed.
