4 Characteristics of digital models □ “a set of ontological commitments” □ Expressed in a “formal language” □ Based on a “fragmentary theory of intelligent reasoning” and “shaped by the need for efficient computation ” John Unsworth, “What is Humanities Computing and What is Not?”, 2002.

5 Text encoding □ Ontology: DTD □ Formal language: XML □ Manipulations: XSLT

6 Artificial Intelligence □ Reliant on algorithms □ Alan Turing’s concept of “The Universal Machine” □ John Searle’s “Chinese Room Argument”Chinese Room Argument

7 Assignment 2

8 □ Exports from UBL catalogue □ Records contain data books and about correspondence □ Groups firstly work separately on assignments; results discussed during presentations Research project during the Seminar

9 MARC-XML SVG

10 XPath □ Language for finding information in an XML document □ Nodes and tokens □ Xpath expressions are always interpreted in a context

11 e.g. if context is set at “literatureList”: item/fullTitle/title

12 e.g. All elements below “imprint”: item/imprint/*

13 e.g. Elements on any location //title

14 e.g. Selecting the value of an attribute: item/language/@languageCode

15 e.g. Selecting only if a condition is true: item/language[ @languageCode = ‘eng’ ]

16 Counts the number of elements on a particular location count() function

20 □ Use to select all the elements of the same type on a certain level □ Takes @select, to point to the node □ Note: changes the context of its children!

21 □ Use to sort a list alphabeticaly or numerically, by the element in the @select attribute □ must be the direct child of (or )

22 □ Select an element on the condition that it is present Date:
