  1. The START InformationAccess System Boris Katz http://www.ai.mit.edu/projects/infolab/

  2. The Problem: • Finding information on line • Two Approaches: • 1. Keyword search (search engines, e.g., AltaVista) • 2. Natural language processing

  3. What’s Wrong with Keyword Search?

  4. What’s Right About Natural Language Processing?

  5. What’s Wrong with Natural Language Processing (today)? • 1. Too hard • Full-text NL understanding still beyond reach • Intersentential reference • Paraphrasing • Summarization • Common sense implication • 2. Too slow • 3. Not all information is language • Most Web resources are not textual • Maps and Images • Sound and Video • Multimedia • Web resources are distributed across numerous non-traditional databases

  6. What is START? • START (SynTactic Analysis using Reversible Transformations) provides multimedia information access using natural language. • Natural language • Natural language is human language. You don’t have to learn a special language to use START. Ask your questions in English; enter information using English. • Multimedia access using natural language annotations • START lets you use English to access any kind of information: text, pictures, movies, and more. • “Just the right information” • START gives you the answer you want without including a thousand others. • Virtual collaboration • START retrieves information from its own knowledge base and from databases all over the Web.

  7. Natural Language • Natural language is human language. You don’t have to learn a special language to use START. Ask your questions in English; enter information using English

  8. Multimedia Access Using Natural Language Annotations • START lets you use English to access anykind of information: text, pictures, movies, and more.

  9. Just the Right Information • START gives you the answer you want without including a thousand other answers.

  10. Virtual Collaboration • START retrieves information from its own knowledge base and from databases all over the Web.

  11. Natural Language Annotations • Bridge the gap between our ability to analyze natural language sentences and other information and our desire to access the huge amount of data now available on the Web. • Annotations are collections of natural language sentences and phrases that describe the content of various information segments. • START • analyzes these annotations • creates the necessary representational structures • produces special pointers to the information segments summarized by the annotations.
