4. Benefit
• Better interpretation of topics through ontologies
• Qualified hits for your search
• Thematic interpretation leads to more turn over
requirement:
Without well maintained metadata you will not get sufficient
search results within the semantic search
6. Booksearch today
• Even very popular book searches (opac, VLB, amazon, etcetera.)
use only search functionalities in bibliographic metadata:
• Means:
– author
– title
– and key words
7. Book search today
• Qualität of search result depends on quality of search strings
• Minor problems in formulating the search striing lead to big problems
in the search result
• Orthographic mistakes
– franz geuenthner no hits / franz guenthner 50 hits
• Morphologic mistakes
– They have six childrens
• Syntactic mistakes
– The professor said on Monday he would give an exam.
– The chicken is ready to eat.
8. goal: more than metadata
Next to static metadata you
receive dynamic extracted
associations as part of your
individual search.
13. future challenges / research
• Identification of existing ontologies
• Tools for indexing full text
• Scalable and high performance database for
handling term indexes with millions of Terms in an
ontology
• Tools for manual developments of ontologies
