1
Ontos Project n Ontology Parser n Data Frame/Ontology Definition n Relevance Detection n Coarse Structure Detection n Constant/Keyword Matching n Database Instance Generator n Other Techniques n Programming Projects
2
Ontology Parser n Essentially complete –Can use clean-up –Documentation n Will change as we refine our data frames
3
Data Frames/Ontology Def n n Value & Required Context n Confidence-Enhancing Context n Lexicons n Macros n On-The-Fly Lexicons n Local Refinement n Evaluation Strategy
4
Data Frames (The Future) n Define Operators n Define Transformations –e.g., canonicalize dates n Define Common Libraries
5
Relevance Detection or Ontology-Enabled Spider n Intelligent Gatherer of Pages n Query Language Issues
6
Coarse Structure Detection n Record Boundary Detection n Nested Structure Detection –Narrow the portion of the ontology and the portion of the document we’re considering at a given time.
7
Constant/Keyword Matching n Finish Translation to New Data Frame –Macro/Lexicon/On-the-Fly Lexicon Matching I should do this –Context Expression Matching Someone else could jump in here n Work on Efficiency Issues n Implement Multiple Passes Someone else could help with this
8
Database Instance Generator n Rewrite Heuristics in Java n Rewrite Heuristics Declaratively –Perhaps we can write these directly in OSM’s Harmony language n Take Advantage of More Constraints –E.g., general constraints, co-occurrence constraints, etc.
9
Other Techniques We Can Apply n Natural Language Processing n Artificial Intelligence n …
10
Ontos-Related Java Programming Projects n Graphical Data Frame/Ontology Editor n Graphical Display of Results n Rewrite OROMatcher Library?
11
Rearchitect n Be sure we’re not monolithic
