Early  Music  Online  (EMO,  JISC  Rapid  Digi&sa&on,  2011)  

Digi&sed  from  archival  microfilms  and  newly  catalogued  by  the  BL  300  books  of  16th-­‐century  printed  music  Roughly  10,000  pieces  of  music  Most  is  vocal  music  in  partbooks,  not  scores  About  30  books  in  various  forms  of  tablature  (mostly  lute,  but  also  guitar  and  keyboard);  including  many  arrangements  of  vocal  music

EMO  metadata  

BL  MARC  records  exported  as  XML  New  cataloguing  includes  a  range  of  types  of  musicological,  bibliographical  and  historical  informa&on  Also  o[en  includes  details  of  physical  condi&on,  prin&ng  history  and  ownership  Lists  musical  contents  with  composers  where  known,  but  does  not  describe  detailed  loca&ons  of  musical  items  in  the  part-­‐books  Names  can  include  composers,  poets,  printers,  publishers,  sponsors,  dedicatees,  owners  (early  and  modern)

SLICKMEM  Objec&ves    Establish  concept-­‐lists  for  EMO  person  names,  places,  dates,  and  work-­‐&tles;  evaluate  exis&ng  ontologies;  basic  RDF  of  EMO  metadata    Express  similar  concepts  in  EMO  metadata  with  Similarity  Ontology    Link  EMO/ECOLM  metadata  to  external  resources    Extract  music  features  (pitch/  &me,  chroma)  from  encoded  lute  and  vocal  music;  test  geometric  &  n-­‐gram  pa`ern-­‐matching  across  EMO/ECOLM  Develop  pilot  Music  Descrip&on  Ontology  to  express  musical  features

Sources  of  error  

OCR  errors  (necessitate  human  interven&on)  Cataloguers  have  to  deal  with:  

16-­‐c  spelling  conven&ons  (not  really  errors  as  such)  Prin&ng  errors  and  conven&ons,  abbrevia&ons,  etc.  Some  names  exis&ng  in  a  wide  variety  of  forms  The  same  musical  work  exis&ng  under  various  &tles  

Cataloguers  some&mes  make  mistakes,  too!

Authority  lists  

BL  uses  the  Library  of  Congress  Name  Authority  files  for  personal  names  There  are  very  few  such  lists  for  musical  works  Rela&vely  li`le  of  the  music  in  EMO  has  been  recorded  What  about  the  rest?

Music  Informa&on  Retrieval  (MIR)  

We  can  use  symbolic  MIR  methods  to  ascertain  iden&ty  of  musical  works  and  disambiguate  conflicts  Similar  techniques  can  be  used  for  music  analysis  and  recogni&on  of  musical  quota&ons  Also  provides  means  to  link  with  external  resources,  such  as  RISM  OPAC  Publishing  cumula&ve  results  of  these  inves&ga&ons  will  provide  a  useful  resource

Future  work  

Hopefully,  EMO  will  soon  expand  to  include  over  2,000  early  printed  music  books  at  BL  Match  score-­‐content  with  recordings  (combining  symbolic  MIR  with  audio  MIR)  Link  EMO  data  with  BBC  Early  Music  Show  archive  as  proof  of  concept  for  wider  linking  of  broadcast  music  with  scores  and  other  resources
