ODW-2013 – 24-Apr-2013

National Library of Latvia (NLL)

• Digital Library “Lettonica”– http://www.lnb.lv/en/digital-library

• Linked Open Data [Publishing]– being added into NLL’s systems

• Examples:– authority data– digital object management system– digital text corpus + named entity database

IMCS, University of Latvia

• Institute of Mathematics and Computer Science (IMCS)– http://www.lumii.lv/resource/show/170

• Open Data– making it easier for people to work with data

(discover, transform, visualize, ...)– interested in collaboration on open data projects

Make it simpler

• working with data must be as easy as possible– *frictionless* (as Rufus says)

• need a data eco-system– [work with] data more useful data

= motivation for the Data Journalism / Data Processing Tool [proposal]

Data Processing Tool

• The Idea:– a tool (or set of tools) covering the whole workflow

• repeatability, provenance, data publishing

– make it easy for people to use open data• graphical modeling, visualization, natural language

• Data Journalism (one of the use cases)– discovery– transformation (clean, filter, integrate, ...)– interpretation (visualization, ...)– developing a story– publishing

Research @ IMCS

• semantic web– data modeling, mapping RDBMS data to RDF, ...

• network analysis and visualization [tools]– http://www.slideshare.net/CaptSolo/exploring-th

• computational linguistics– named entity and relationship extraction– natural language interfaces

in the context of Data Web

• important [for the web]:– data discovery– data publishing

• publish the data along with the story– make it easy to publish data as a part of the data

journalism workflow– make data discoverable for re-use– [automatically] maintain provenance info
