Linking Library Data with Fusepool

ContextI 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 tolocal 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


Workflow1. 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

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!
