Similarities between technologies Ontologies: DTD and ERD Data formats: XML or formats in relational databases Manipulations: XSLT and SQL

Critique of technologies Critical thinking about tools and techniques: “Critical Digital Humanities” All techniques also have limitations; they are based on assumptions which may be questioned XML, for instance, assumes that all texts have a hierarchical structure

Digital Humanities Focus on the various ways in which the computer can be used to investigate traditional questions in the humanities “things […] that could not be done feasibly without the computational power and storage modern computers provide” (Philip Burns, Day of DH 2013)

It brings computational techniques to bear on traditional humanistic questions It studies the phenomenon of computation from a humanities perspective, and aims to understand the implications of using computers in humanities research

Critical Digital Humanities cf. Alan Liu “Where is Cultural Criticism in the Digital Humanities?” or David Berry, The Philosophy of Software Social and cultural implications of software, cf. Langdon Winner Effects on the research agenda

Differences with traditional research The work is of a practical nature (‘more hack and less yack’) It leads to different (non-textual) forms of output Difficult to make such results count in assessment of scholarly productivity Collaborative form of research New questions? GIS

Institutionalisation at LU Centre for Digital Humanities Leiden University Centre for Data Science Centre for Digital Scholarship GIS

Digital Text and Data Processing Relatively new specialisation Distant reading; Quantitative analyses of literature Programming in Perl Statistical analyses using R No prior knowledge is needed

Individual research projects

Seminar 13 december A second ’hackathon’ Based on the same data set Implemented as a relational database SQL to analyse the data and to make visualisations
