Hot NLP Problems
• Graphical Methods for NLP – Social network analysis
• Text categorization– Sentence / Citation function
• Sequence Labeling– Reference string parsing
• Bayesian Models– Topic Models
• Summarization– Survey Paper Generation

The Anthology as Corpus
Why use newswire?– Because our funding agencies want it
Let's build a corpus from our own publications!– Test domain adaptation techniques– Characterize what’s special about scientific discourse– Help ourselves and others understand our research better
Start with the largest freelyavailable NLP research archive
27-31 May 2008 LREC 2008 (Marrakech, Morocco)

The Anthology Reference Corpus
Scholars have already been using scientific articles as input
But datasets largely disparate
Results not comparable
Goal: unify such work by agreeing to work on a central dataset (à la TREC)
27-31 May 2008 LREC 2008 (Marrakech, Morocco)

The ACL ARC
Consists of most articles available as of February 2006 that have extractable text
Papers 10,921Total References 152,546References to articles 38,767 (25.4%)inside ACL ARCReferences to articles 113,779 (74.6%)outside ACL ARC

What’s included now
Version 2008 03 25:– PDFs for all 10,921 articles
– <Title, Author, Booktitle> metadata tuples
– Noisy, text extracted output from the PDFs• Using non-OCR based extractor (pdfbox)
27-31 May 2008 LREC 2008 (Marrakech, Morocco)

The road ahead
1. Improve data quality
2. Establish subsets for smaller experiments
3. Build and release open-source tools
4. Enlarge coverage of newer materials
5. Release major revisions (infrequently)
Achieving the goals of the Linked Anthology Proposal
27-31 May 2008 LREC 2008 (Marrakech, Morocco)
11
Future data (near-term)
Inter-document– Manually cleaned citation graph
from the ACL Anthology Network
Intra-document – Citation to reference string matching
Document– Automatic keyphrase generation– OCR based text extracted output
(much cleaner)

Tools in development by partners
Automatic Reference Segmentation:• ParsCit: Open-source reference string parser; also LREC 08
Automatic Survey Article Generation• iOpener: summarization of articles at different expertise levels
Automatic Reference-Article matching• Record Linkage: using web data to match articles
Citation Function Classification• What’s the purpose of a citation?
Next big application• Your work here: please join us – this should be a community wide effort
