Exploring Semantic Means

This 2009 New York Semantic Web Meetup presentation discusses the potential of the semantic web to enhance knowledge connectivity and improve exploratory search processes. It emphasizes the significance of understanding user intent in information retrieval and the necessity of a human-computer information retrieval model that fosters user engagement and responsibility. It also highlights examples and applications of exploratory search, underscoring that exploration is crucial for the advancement of semantic technology.

8. © 2009 Endeca Technologies, Inc. All rights reserved. 8 exploratory search what i really care about what you should care about too especially if you see more to information seeking than google
9. © 2009 Endeca Technologies, Inc. All rights reserved. 9 what would google do? information Need query select from results rank using IR model USER: SYSTEM: tf-idf PageRank
10. © 2009 Endeca Technologies, Inc. All rights reserved. 10 assumptions of relevance-centric approach • self-awareness • self-expression • model knows best • answer is a document • one-shot query
11. © 2009 Endeca Technologies, Inc.

16. © 2009 Endeca Technologies, Inc. All rights reserved. 16 tags provide summarization and guidance
17. © 2009 Endeca Technologies, Inc. All rights reserved. 17 my information need evolves as i learn
18. © 2009 Endeca Technologies, Inc. All rights reserved. 18 how did we do that? • wisdom of crowds • corpus analysis • scope the problem • target exploratory search
19. © 2009 Endeca Technologies, Inc. All rights reserved. 19 if you prefer sports to computer science
20. © 2009 Endeca Technologies, Inc. All rights reserved. 20 a more current slide…
21. © 2009 Endeca Technologies, Inc. All rights reserved. 21 hcir can get fancy
22. © 2009 Endeca Technologies, Inc. All rights reserved. 22 and there’s query structure side of semantics
23. © 2009 Endeca Technologies, Inc. All rights reserved. 23 a more current example All reviewers Reviewers Under 18
24. © 2009 Endeca Technologies, Inc.

25. © 2009 Endeca Technologies, Inc. All rights reserved. 25 still in private beta…
26. © 2009 Endeca Technologies, Inc. All rights reserved. 26 following the information scent
27. © 2009 Endeca Technologies, Inc. All rights reserved. 27 to explore the news
28. © 2009 Endeca Technologies, Inc. All rights reserved. 28 in closing let’s not quibble over protocols exploration is the killer app for semantic tech it’s real, and it’s fabulous!
