1. Finding Connections: Musical Collections and Social Networks Tim Crawford & Ben Fields (Goldsmiths)
2. Early Music Online & ECOLM EMO (Early Music Online): c. 300 music sources printed before 1600 includes 28 lute sources in tablature (1,087 pieces), each of which contain arrangements of vocal music 3 keyboard tablature books (c. 230 pieces) ECOLM (Electronic Corpus of Lute Music): c. 3,000 pieces in tablature, encoded in TabCode to allow playback, transcription, analysis & searching includes 10 lute books from EMO (c. 500 pieces - soon)
3. Music ingestion and data correction Optical Mensural Music & Tablature Recognition -> Encoded music, but needs: Correction of (inevitable) OCR errors Collation Metadata – supplied by BL, but needs: Parsing MARC structure into a relational database Correction of (inevitable) human errors Alignment with encoded music
4. Tools for musicologists or librarians Web-based, because: Needs no special installations Just require a modern computer and internet Access to databases and other external resources well supported Graphical interfaces, images, audio, interaction are the norm Even music notation is (now) easy to render – as Laurent Pugin showed us earlier
5. Music ingestion and data correction Optical Tablature Recognition in ECOLM (Gamera) Encoded music Correction of (inevitable) OCR errors Collation Metadata Cleaning up structure Correction of (inevitable) human errors Alignment with encoded music
6. ECOLM Tablature editor
7. Music ingestion and data correction Optical Tablature Recognition in ECOLM Encoded music Correction of (inevitable) OCR errors Collation of corrections from two experts Metadata Cleaning up structure Correction of (inevitable) human errors Alignment with encoded music
8. ECOLM Collator
9. Music ingestion and data correction Optical Music (& Tablature) Recognition Encoded music Correction of (inevitable) OCR errors Collation Metadata Cleaning up structure Correction of (inevitable) human errors Alignment with encoded music
11. What music is contained in this image? Where do pieces begin and end on the page? Where are the other voice-parts?
12. Music ingestion and data correction Optical Mensural Music Recognition (Aruspix)! Encoded music (MEI)! Correction of (inevitable) OCR errors! Collation! Metadata! Cleaning up structure! Correction of (inevitable) human errors! Alignment with encoded music

14. A madrigal for four voices (score)
15. EMO Collator
16. ECOLM Search Searches within ECOLM Metadata Content External searches Audio EMO (RISM, etc. – one day)
17. social-network analytics and music Social Network Analytics: methods to describe and analyse complex networks that concern social relationships
18. social-network analytics and music Music curation and the Web
19. Tools I use •networkX •iGraph •graphViz •Gephi •postgresql
20. Common Techniques •diameter •average degree •shortest path problem (common solution: Dijkstra’s algorithm) •edge betweenness •community segmentation
