Report on the 3rd Learning Language in Logic Workshop (LLL-01)
Strasbourg, France, September 8-9, 2001

Lubos Popelinsky

 

The Learning Language in Logic Workshop (LLL-01), held on 8-9 September 2001 in Strasbourg, France was the third in a series of LLL workshops. The previous two were held in 1999 in Bled, Slovenia, and in 2000 in Lisboa, Portugal. The LLL workshop was co-located with the ILP-01, with which it shared a joint session.

The program of the workshop split into two parts. Work-in-progress papers were presented in the afternoon of September 8.

Six papers (out of the 8 submitted) addressed different topics in computational linguistics. The first session focused on current research trends in learning categorial grammars and contained the following papers:

• From Logic to Grammars via Types
  Dudau-Sofronie D., Tellier I., Tommasi M.
• Learning Rigid Lambek Grammars and Minimalist Grammars from Structured Sentences
  Retore C., Bonato R.
• Identification reversible dependency tree languages
  Besombes J., Marion J.-Y.

The second session addressed current applications of ILP in NLP and contained the following papers

• A Rule-Based Tagger Development Framework
  Alexin Z. et al.
• Part-of-Speech Tagging by Means of Shallow Parsing, ILP and Active Learning
  Nepil M., Popelinsky L., Zackova E.
• Interactive Background Knowledge Acquisition for Inducing Differences among Documents
  Nakabasami C.

The session on September 9 was a joint session of LLL-01 and ILP-01. Dan Roth, the invited speaker of LLL-01, presented a novel approach to relational learning in NLP, based on constructing many features and learning efficiently from them. This was a very interesting talk and the ILP community would do well to pay this work more attention. The rest of this morning session consisted of papers from ILP-01, which included two talks related to LLL:

• Automated Parser Construction from a Treebank by means of TBL and ILP
  Miloslav Nepil
• Deductive and Inductive Reasoning on Semi-Structured Documents Modelled with Hedges
  Akihiro Yamamoto, Kimihito Ito, Akira Ishino & Hiroki Arimura

The number of participants registered for LLL-01 was 32.

The proceedings of LLL-01 have been released as a technical report at the Faculty of Informatics, Masaryk University, Brno:
