• Paraphrase set no longer changes w/ pagination
• Various instance-of queries are now collapsed together.

Oct 25

• Improved results UI to highlight paraphrase info and display system reasoning from question to extracted relations.
• Discussed w/ Stephen, feedback:
  • Add a paraphrase section at top of page to highlight top paraphrases, w/ accordion to display all paraphrases.
  • Add accordion effect to results section, display top paraphrase's results by default, collapse rest.
  • Add a "query interpretation" under each executed paraphrase.
  • Save screen area where possible around freebase card.
• Discussed w/ Michael, feedback:
  • Reduce lines around paraphrase results section.
  • Don't close one accordion section when another is opened.
  • Improve display of sentences - at least number them. Maybe center justify and truncate.
  • Maybe remove "Extracted Synonyms" section.
  • Support "What do we know about X?" questions?

Oct 18

• Upgraded UI toolkit to latest version of Twitter Bootstrap
• Upgraded to most recent development snapshot of Paralex backend.

Oct 17

• Next Steps:
  • Shift focus away from research/backend towards demo/UI until a stable demo is available.
  • Implement results page UI by 10-23
• Completed:
  • Created UI demo mockups and received feedback from Stephen and Oren:
    • UI Mockups
  • Chose example query set to satisfy constraints:
    • Non-trivial to parse
    • Handled well by paralex
    • Answerable in the triplestore
  • Example queries are:
    • Foods from Africa?
    • Is there any cure for cancer?
    • Are there any famous people from Detroit?
    • How fast are cheetahs?
    • Sources of Antioxidants?
    • Is Obama married and to who?

Oct 9

• Analyzed improved paraphrase template scores from Tony
• Discussed UI layout with Stephen:
  • Show list of answers as in current demo.
  • Clicking an answer should reveal paraphrases that lead to the answer.
  • Clicking a paraphrase should expand to show sentences that contain triples used to derive the answer.

Current Goals:

• Find set of example questions with high-quality paraphrases by Oct 11
• Mockup results UI by Oct 16
