Fusepool ﬁnal public workshop!
Brussels, June 25th – Johannes Hercher, Free University Berlin, University Library
Context
I care for metadata Ugh!  
Your OPAC sucks
We
cooperate…
How to link Library Data
with the „Oceans“ of WWW ?
German
National Library
published authority
data

Example
a search in subject index (with GND Identifiers)
a search in full text http://primo.fu-berlin.de
• GND = Thesaurus for
subject indexing in Germany
• Search with GND limited to 
local resources

• search beyond the local
holdings => easier, more reliable
• suggest content using
semantic relations  
( GND is a Thesaurus ! )
You* should use
identiﬁers
*publishers, authors, aggregators
Assigning IDs  
is time consuming
- Reality -
Assigning IDs  
is fun
- Vision -

Questions & Tasks
• Could machines do the subject indexing? 
-> Use SMA to enrich DBpedia pages with GND IDs
• Can we support Librarians in subject indexing?  
-> Build Annotator Prototype  
 
https://github.com/jhercher/LEE/

Demonstrator
AnnotatorApp:  
filters stoppwords and
displays Library entities
for your text

Review concepts and
start a search using concept id’s

How to Fusepool

Workﬂow
1. Select a subset of GND Subject Headings using SPARQL
2. Import Subject Headings
3. Conﬁgure SMA dictionary component
4. Import documents (Graph)
5. Batch matching of documents with dictionaries using
Fusepools DLC
6. Review results and build services on top

• GND Dictionary includes: articles, prepositions, adjectives…
• Acronyms („IM, DES“) -> activate „Case Sensitivity“
• Not every match is useful in the context („August, Defeat“)

Drawback:  
Quality of annotations
depend on text input

Feedback

Why Fusepool?
1. Ready for the Semantic Web"
• can handle graphs (clerezza, TDB,…)
• Data i/o using REST
2. String Matching SMA"
• Import & conﬁguration of dictionaries (e.g. a Thesaurus)
• batch matching & annotation using Data Life Center (DLC)
3. Easy to install Builds at http://jenkins.fusepool.info

Conclusion
!
• Fusepool: Infrastructure to build new services
• … better linking beyond the aquarium(s)
• TODO:
• build tailored interfaces for annotation, search, recommender
• improve the dictionaries

Thank You!
