Why historians should be
interested:
Old New CHANGE
Analogue resources Digital resources
SCALE
Small data Big data
Close reading Distant reading TECHNOLOGY

the Big Data revolution?
Big data and claims about a paradigm change in the
humanities

Patterns and structures: a new essentialism?

Based upon changes of scale & method: humanities
supposedly becoming more ‘scientific’ > results can be
checked and replicated, but can they? Interpretation.

Politics: funding & valorisation

“One of the problems confronting data enthusiasts in
the humanities is that we feel a need to convince our
more old-fashioned colleagues about what can be done.
But our role as advocates of data shouldn't mean that
we lose our critical sense as scholars.
[....] there is a risk that we look more carefully at the
technical components of the datasets than the
historical context of the information that they represent.

January 2013).

Searching digital libraries & archives…

composition of resources, selection…

example of Compactmemory: a great resource on
German-Jewish history

Die Sammlung umfasst die 110 wichtigsten jüdischen
Zeitungen und Zeitschriften des deutschsprachigen Raumes
aus den Jahren 1806-1938. Die Periodika repräsentieren die
gesamte religiöse, politische, soziale, literarische oder
wissenschaftliche Bandbreite der jüdischen Gemeinschaft.
but be aware of selection: focus on elites and organisations that
highlight German Jewry’s process of emancipation :
• classical vision in historiography on German Jewry?
• reinforcement of existing master narratives?

Processing and searching data on your own
computer…

data?
data = computer-processable information

Many digital libraries/archives:
un-/semi-structured data

Digital editions: bridging the gap with XML

•Google/ Bing/ Yahoo
• er is veel meer ...
• resultaten verschillen per zoekmachine
• en er is een filter bubbel
•--> kortom: weten wat je zoekt en zoekstrategie cruciaal

Some definitions of data mining:

At its simplest, data mining is the process of extracting
new knowledge (usually in terms of previously unknown
patterns) from sets of data already in existence.
Jonathan Hagood

Data mining (the analysis step of the "Knowledge Discovery in
Databases" process, or KDD), an interdisciplinary subfield of
computer science, is the computational process of discovering
patterns in large data sets involving methods at the intersection
of artificial intelligence, machine learning, statistics, and
database systems.
The overall goal of the data mining process is to extract
information from a data set and transform it into an
understandable structure for further use.
Wikipedia

Examples of projects and techniques

an n-gram is a contiguous sequence of n
items from a given sequence of text or speech

data?
data & data mining ≠ neutral

“What is too often forgotten, though, is that our
digital helpers are full of ‘theory’ and ‘judgement’
already. As with any methodology, they rely on sets
of assumptions, models, and strategies. Theory is
already at work on the most basic level when it
comes to defining units of analysis, algorithms, and
visualisation procedures.”
Bernhard Rieder and Theo Röhle, ‘Digital Methods: Five
Challenges’ in: David M Berry ed., Understanding Digital
Humanities (Houndmills: Palgrave Macmillan, 2012) 67-85,
70.
