  • Coordinating presentation slides and scholarly
    papers
  • Align set of slides to set of paragraphs
  • Difficult as alignment is not monotonic, nil
    alignments possible

  • LINC 2.0 (J. Prabawa)
  • - How to build a better library catalog interface
    using AJAX
  • - 4 key areas of user design change overview
    details, AJAX grid, tabs, suggestion bar,
  • - Usability studies for evaluation
  • - JCDL 2007 short paper

3
Posters
  • Scenario Template Generation (L. Qiu)
  • Joint work with Tat-Seng Chua
  • Create template of slots for articles from
    multiple different event reports
  • Uses EM based context sensitive clustering
  • Phrase-based Statistical MT (H. Setiawan)
  • Joint work with Haizhou Li (I2R)
  • Focus on function words to reorder arguments
    (e.g., English preposition above to Chinese
    postposition ? )
  • Record Linkage using Web resources (Y. F. Tan)
  • - Joint work with Dongwon Lee (PSU)
  • - How to best combine disparate info from various
    sources of web evidence
  • Math IR (J. Zhao)
  • - Working on indexing, retrieving mathematical
    information
  • - Key problem co-ref between formula name
    Pythagorean theorem and equation form and
    variants.
  • Graph-Based Text Summarization (Z. Lin)
  • - Joint work with Wee Sun Lee
  • - Using incrementally built graphs and PageRank
    to build better generic and update summarization
    systems

Aligning slides to scholarly papers
  • Why do it?
  • Slides can be seen as a dual and/or summary of
    papers
  • Useful as a learning and comprehension aid
  • See OCW example in Leslie and Tomas lecture
    notes
  • Whats the goal?
  • A digital library of slides/papers and their
    fine-grained alignment to scholarly papers (an
    extension of CiteSeer or Rexa)
  • What data to use?
  • Seeded with CiteSeer data (thanks to CL Giles),
    merged in DBLP
  • Searched for corresponding ltppt, pdfgt
    presentation using Google API

7
SlideSeer Demo
  • Proof of concept
  • 10 presentation/paper pairs manually aligned
  • Allows focus on one medium with other in context
  • Allows full slideshow mode
  • Navigation using mouse, keyboard shortcuts
  • Search using Lucene IR package

8
Next steps
  • Planning to hook up current work in progress
  • 2 stage CRF/SVM re-ranking citation segmentation
    algorithm
  • Automatic keyphrase extraction program
  • Automatic synthetic image classification
  • Automatic de-deduplication module
  • Partnering with Simone Teufel (Cambridge, UK) to
    do argumentative zoning of documents
  • What is a citation used for?
