what semantic means to (people who pay) me using linguistic and statistical approaches to derive meaning from unstructured text using semantic web approaches to represent meaning in content and query structure

exploratory search what i really care about what you should care about too especially if you see more to information seeking than google

what i really care about

what you should care about too

especially if you see more to information seeking than google

what would google do? information Need query select from results rank using IR model USER: SYSTEM: tf-idf PageRank

assumptions of relevance-centric approach self-awareness self-expression model knows best answer is a document one-shot query

self-awareness

self-expression

model knows best

answer is a document

one-shot query

human-computer information retrieval don’t just guess the user’s intent optimize communication increase user responsibility and control require and reward human intellectual effort “ Toward Human-Computer Information Retrieval” Gary Marchionini

don’t just guess the user’s intent

optimize communication

increase user responsibility and control

require and reward human intellectual effort

google scholar him?

hcir-inspired interface

tags provide summarization and guidance

my information need evolves as i learn

how did we do that? wisdom of crowds corpus analysis scope the problem target exploratory search

wisdom of crowds

corpus analysis

scope the problem

target exploratory search

if you prefer sports to computer science

a more current slide…

hcir can get fancy

and there’s query structure side of semantics

a more current example All reviewers Reviewers Under 18

one last example “…As an example, I may be interested in the tensions between government and newly nationalized banks over the bonus culture that taxpayers are now funding (a hot topic in the UK currently)…” --a commenter at The Noisy Channel, in a discussion of exploratory search for news

still in private beta…

following the information scent

to explore the news

in closing let’s not quibble over protocols exploration is the killer app for semantic tech it’s real, and it’s fabulous!
