The estimated total cost of digitising the collections of Europe’s

museums, archives and libraries, including the audiovisual material

they hold is approximately €100bn, or €10bn per annum for the next 10

years, factoring in a cumulative efficiency gain of 0.5%

per annum.

The Research & Development Budget for the Joint Strike Fighter

programme is estimated at €40.34bn.

It would cost between 10% and 40% of the Joint Strike Fighter R&D

budget to digitise every eligible title in Europe’s libraries

Highlighting search terms

So far, okay. Similar functionality to other national and regional digital libraries of newspapers

But what was the user response to an aggregation of European newspaper libraries ?

Results of Usability Testing: http://www.europeana-newspapers.eu/wp-content/uploads/2014/05/The-European-Library-Newspaper-Archive-Usability-testing-Report-April-2014.pdf

“Aggregated view of content

from many sources highly valued.

There was a strong positive reaction to the availability of

the archive.”

“Many saying they would be keen to return to the site as

the content expands.”

“Ability to search over geographic map was highly valued”

Plenty of quibbles about design

- positions of advanced options- re-order list of results- manipulating facets

Much greater expectations of functionality once logged in

For example,Saved searches

New content notification

“Much of the value of the site to participants was provided by the images of the documents.

Participants expected to be able to save a 'local' copy once they

had located content of relevance.

As no download facility is provided, this led to some frustration and undermined the overall potential value of the site for some

participants.”

Timetable for rest of project

Now – Protype version of interface shared with project

Throughout 2014 - Ongoing creation of OCR, and other

related technical work (OLR, Named Entities)

Throughout 2014 – Live version of website improved /

usability testing / added content

Autumn 2014 - Final project conference

Late 2014 - Newspaper browser completed with content and

tools from project

Things the users didn’t say(but we thought they would)

Why can’t I edit the text ?

(Our sample was researchers/ maybe it is other communities interested in crowdsourcing?)

Note: If time permits, The European Library will develop some crowdsourcing feature

Can I download text for data mining?

Remember: Digital Humanists are still a small percentage of humanists and users

Note: Many, although not all, of the texts are marked public domain, so this is feasible in legal terms

Number of digitised pages in interface: c.2m

Number of digitised pages in European libraries: c.130m

Number of physical pages in European libraries: 1.5bn+

Quantities of newspapers – a) in project b) digitised in total c) in physical libraries

The project digital library is only a fraction of the newspaper

archive of the continent, indeed the world

As libraries, how should we represent that

absence to users ?

Should such absence be represented in the interface itself ?

Vast

white

spaces in the list of results ?

….. Difficult to represent ‘archival gaps’ when seen in the context of how little has been digitised - creates a

needle in the haystack ….

One placeholder for several metadata records ?

But in many cases the metadata does not even

exist, so a search interface has less to work with

Standardised information for

every digital resource for representing collections, extent of content, licencing and re-use conditions

Standardised information? For every digital resource produced in the world ?

Are you kidding ?

Charts and graphs external to the interface ?

Graphs are the most obvious way of adding context

but still very reliant on the library producing such charts

How to derive a representative (random) sample from a digital collection?

Pieter Francois, winner of BL Labs competition 2013:

“How representative are the historical texts humanities scholars study of the overall body of ‘surviving’ texts that are held in the various library collections?”

There are other issues in the project content too

Major issues

OCR quality varies Different licensing statements from

different countries Date of copyright boundaries different in

each country

There are other issues in the interface too

Minor Issues

Some pages (2m by 2015) have articles segmentation

Some library content has named entity extraction effecting search results

What impact do OCR errors have when text mining a large digital collection?

Source: http://homepages.inf.ed.ac.uk/balex/publications/slides-DATeCH.pdf

10M pages, 7 billion words – how much you are actually ignoring when using only the “good” OCR

How should we allow users better ways to

understand the digital library ?

What role can the API play in this?

Can opening up the data in the digital library and allowing it to explored in different ways ?

Traditional Model With an API

Interface(Created by Library)

Data(Published by Library)

Interface(Created by Third Party)

Data(Published by Library)

API – Application Programming Interfaces

Pioneering work of Trove API(or rather of Tim Sherratt)

Interface(Created by Library)

Data(Published by Library)

Trove Newspapers site as published by National Library

of Australia, and based on data provided by Libraryhttp://trove.nla.gov.au/newspaper

Trove Newspapers statistics develolped by third party, based

on data provided by libraryhttp://wraggelabs.com/shed/trove/graphs/

Interface(Created by Third Party)

Data(Published by Library)

Headline Roulette, developed by third party, based on data

provided by libraryhttp://wraggelabs.com/shed/headline-

Sounds great !But … ?

How many people in this audience would now how to build an interface on top of API?

How many users do you know who could build on top of an API ?

That is the problem I leave you to discuss

Thank you.
