UNEDITED NOTES

DPLA: placename resolution

• matching against Geonames
• staff discomfort
• lack subject expertise in aggregated data

Entity recognition

• use entire record as context for resolution
• points vs. shapes in geo entity resolution
• crowdsourcing opportunity?
• OCLC - several passes through data, information from multiple sources (ISNI, VIAF, etc.)
• need public feedback for last 20%
• refine algorithms based on crowdsourcing feedback
• machine transformation and confidence rating – mark that is machine-generated, with date

(new group)

strings --> things

• need string info in perpetuity
• accuracy, testability of ambiguity
• places ... think maps ...
• people
• dates ... map interface
• subjects

libraries divide and conquer entity cataloging

post-processing tools

• human mediation
• less human mediation
• hybrid models – e.g., obit project
• akin to OCR post-processing

accuracy tools

• page rank algorithm
• BibFrame converter – work accuracy?

entity extraction

• from metadata – how structured is it?
• lots of text – algorithms better

how motivate users to take tools/data for a spin?

what if we had no metadata and started only with full text?

(new group)

challenges

• solutions – would be awesome

parsing MARC to find translaters and role

• roles as strings should be things

person reconciliation

• requires human review
• resolve ambiguity in identity, roles, contributions
• predicates restrict detail
  • e.g., performer vs. violinist

crowd sourcing

• simple problems or too complex, requires experts?

music parsing

image identity

(new group)

UCSD – mix of auto & manual review

CERL – name, spelling & disambiguation

HBS – URIs provided by authority vendor

Create local auth record/URI for strings with no auth?

Feed into LC or OCLC for needed authorities?

Improve cataloging tools with type-ahead entity resolution
