  21. 21. NLP development methodology Step 1 find out what the ‘mark up’ should be (from historians) Step 2 ask historians to mark up some documents manually Step 3 use some of these examples to develop an NLP system that does ‘the same’ Step 4 use the rest to evaluate its performance (in progress)

  27. 27. NLP – layered pattern matching Token layer: identify semantic types and intrinsic properties (eg gender) of known individual words (not all of these types feature in the final output). Some types are inferred – eg unknown capitalised words are proper nouns.
  28. 28. NLP – layered pattern matching Token layer: identify semantic types and intrinsic properties (eg gender) of known individual words (not all of these types feature in the final output). Some types are inferred – eg unknown capitalised words are proper nouns.
  29. 29. NLP – layered pattern matching Lexical layer: identify simple lexical phrases – groups of tokens that act as individual units. Promote other individual tokens to lexical items (with lexical types).
  30. 30. NLP – layered pattern matching Lexical layer: identify simple lexical phrases – groups of tokens that act as individual units. Promote other individual tokens to lexical items (with lexical types).
  31. 31. NLP – layered pattern matching Syntax layer: build (local) syntactic structure to identify basic constituents of the sentence.
  32. 32. NLP – layered pattern matching Phrasal layer: use part-of-speech tags to build lexical items into local syntactic/semantic structures. These have lots of unbound arguments – like jigsaw pieces waiting to be slotted together.
  33. 33. NLP – layered pattern matching Phrasal layer: use part-of-speech tags to build lexical items into local syntactic/semantic structures – and then ’collapse’ all the equals relations.
  34. 34. NLP – layered pattern matching Semantic layer: build semantic relationships by gluing the pieces together. Again, first we use equals relations to capture the structure
  35. 35. NLP – layered pattern matching Semantic layer: build semantic relationships – and then we collapse them down
  36. 36. How did we do? Grant by Thomas son of Josce goldsmith and citizen of York to his younger son Jeremy of half his land lying in length from Petergate at the churchyard of St. Peter to houses of the prebend of Ampleford and in breadth from Steyngate to land which mag. Simon de Evesham inhabited;
  37. 37. How did we do?
  38. 38. Historians vs NLP • NLP has to be told very clearly what it is looking for • NLP has to make a lot of information explicit that people don’t notice • NLP sees ambiguity where people do not – Really struggles with coordination and attachment • NLP is programmed by computer scientists (or sometimes statisticians), not historians • NLP can do it, but it definitely needs help !
  39. 39. Reconstructing spatial relationships from charters: a collaboration between Data Mining and Historical Topography Stefania Merlo Perring, Sarah Rees Jones, York Arno Knobbe, Leiden
  40. 40. This presentation will : • Introduce the process used by Data Mining to reproduce the methodology of historic topography • Discuss the results and further potentials • Reflect on how Data Mining of charters and cartularies can add new meanings to Diplomatics

  52. 52. Free from previous hierarchies People, sites and events: all are nodes in a network
  53. 53. New indexes and catalogues
  54. 54. Conclusions/suggestionsfor debate • People, institutions, things and technical devices represented as nodes (actors) in a network are freed from previous categories and hierarchies (Actor- Network-Theory, Callon 1991, Latour 1992, 2005) • Nodes and patterns in a network are starting points for analysis and can generate new research questions and insights • Networks connecting information from different fonds have potential for creating alternative virtual archives • These can be created for a person or for a place (e.g. grouping charters concerning the same location)
