• Extract manifestations and items from records
• Identify and split aggregative records
• Cluster record set to identify works
• Cluster work sets to identify expressions
• Create entities from the clusters

Obstacles to the Automatic Creation FRBR Model Instances• Inconsistency of data in catalogs:
– Identical information is represented differently in different records (attributes, syntaxes)
– Erroneous data
• Incompleteness of data in catalogs:– Information necessary for clustering has not been
captured in the records

Obstacles to the Automatic Creation FRBR Model Instances• Inconsistency of data in catalogs:
– Identical information is represented differently in different records (attributes, syntaxes)
– Erroneous data
Might be resolved automaticaly,for example, through authority files

captured in the records

An increasingly interconnected environment
• 為何環境有越來越多的連結需求– 數位時代圖書館需有更多的系統支援– 聯盟的成立及其他的合作計畫迫使系統需連結– 需與非圖書館單位連結,如校園入口網站或教
學系統– 跨應用系統的單一授權服務
