ARCHITECTURE, LIBRARY AND INFORMATION SCIENCE

Some Topics & Trends


Challenges for Libraries

•  Increasing informaJon volume

•  New data / media formats, e.g. 3D models

•  Document aggregaJons, enhanced publicaJons, increasingly hybrid, need for data exploraJon

•  WWW: extending search space (instead catalog silos), affecJng scienJfic communicaJon and publicaJon (eScience)

-‐ Facing the 21st Century

13.11.14 NLUS 1st Workshop, HTW Chur Dr. Ina Blümel, TIB & HS Hannover

NLUS Topics: relaJon of actors/things

•  Library services for architects?

•  Library architecture? (usage, „3rd place“, organisaJon of spaces and services)

EXPLORING ARCHITECTURE

Access to 3D document aggregaJons: ContextualizaJon enabling exploraJve search Taking informa0on to users, understanding users‘ needs


ExploraJon

•  Objects •  Places •  Actors •  Events •  Concepts

•  Aggregated documents •  Contained data

ExploraJve search and browsing must try to face and tackle the challenges posed by the brain – Human minds are able to link 1) everything, 2) everywhere, and in 3) any Jme period

Graph based modeling

•  Using •  RDF/RDFS •  SKOS, DC, DCterms, FOAF •  FRBRoo/CIDOC-‐CRM,

alternaJve EDM •  + few arch.-‐related

datasets

Towards mapping human associaJons


Some notes

•  ConnecJng architects, buildings, places, .. •  Without language barrier •  Linked Open Data •  Re-‐usable in any applicaJon •  (VIVO) •  HarvesJng from privatly curated web pages


Similarity

10

•  Similarity as key point for the generaJon of suggesJons •  Cannot be considered isolated from context, more simply: "Similarly, with

respect to which aspects?“ •  different similarity contexts may lead to completely different suggesJons

Open quesJons

ClassificaJon might use AAT Geny Vocabulary, DBPedia Ontology and/or Wikidata ..

Research QuesJon

ENRICHMENT WITH METADATA OF DIFFERENT SEMANTIC LEVELS: DATA-‐ AND DOMAIN-‐SPECIFIC EXTRACTION METHODS

#content


What‘s inside?

§  no explicitly available informaJon (few well defined enJJes like in textual data) à need for metadata, but

§  poor metadata annotaJon available, therefore à  Need for indexing and classificaJon algorithms •  (tailored to domain data and community requirements)

17

opened in CAD editor… Machine view: definiJon of verJces / faces, no semanJcs


Research QuesJon

Digging for semanJcs

AutomaJc cuwng into floors, extracJon of room strucure

¨  Technical + content based metadata ¤  Total number of floors à building type ¤  Amount of windows, doors, … ¤  Floor area ¤  …

OPEN ISSUES


•  3D makerspaces. Problem of surfaces

•  Open Data in architecture? •  Plaxorms, data sharing, trends


More challenges + discussion •  Need for improving coherence and alignment of existing (domain

related) ontologies towards a unified knowledge graph •  Need for reliable information about content, provenance,

availability, data types contained in or temporal evolution of distributed datasets

à  Role for Libraries: curation of dataset catalogs containing

meaningful metadata about domain related datasets (independent of their original intention) –  Facilitate selection of schemes for auto classification to gradually

enrich models with semantics Some tasks go bener with crowdsourcing or NER of textual context – let’s combine!

–  Enabling humans to explore suitable data


§  Relations between entities that are relevant to the information object

§  allow exploratory search , browsing and search suggestions.

Searching

•  User knows neither object nor desired informaJon exactly •  .. does not know necessary query for the so-‐called "known-‐item“ •  Request cannot be formulated exact, only fuzzy

„Nobody understands me :(“

"I remember my mom telling me that her grand-‐grand ma once went to this nice place in Europe to visit the world's fair. People spoke French and she saw this huge tower made of steel. Mom told me the name of the architect, but I can't remember it." à Suitable search query?
