From: Sebastian Pado <>
Subject: Shallow Semantic Parser, New Release

Dear all,

This is to announce the release 1.1 of Shalmaneser (a SHALlow seMANticparSER), a system for automatic sense assignment and semantic rolelabeling. Shalmaneser comes with pre-trained FrameNet classifiers forEnglish and German. (Further details below.)

Improvements over the previous release (1.0) include:

- Pre-trained English classifiers for FrameNet release 1.3 (i.e. improvedcoverage and accuracy)- Support for TreeTagger as POS Tagger for both English and German- Removal of numerous bugs

You can download the software from this URL:

Again, please let us know if you have any questions, comments, or suggestions!

Best,Sebastian Pado and Katrin Erk

--Purpose of Shalmaneser

Shalmaneser has been developed with two uses in mind: research inapplications that use shallow semantic parses, and research on bettershallow semantic parsing. So Shalmaneser can be used either as a 'blackbox' to obtain semantic parses for free text, or as a research platformthat can be extended to new parsers, languages, or classification paradigms.

Features of Shalmaneser

- Shallow semantic parser: word sense disambiguation for predicates, plussemantic role labeling- Input: plain text. Syntactic processing integrated- Classifiers available: trained on FrameNet data for English and German(System also applicable to other frameworks)- System output can be viewed graphically in the SALTO viewer: System realized as a toolchain of independent modules communicatingthrough a common XML format, hence extensible by further modules- Interfaces for addition/exchange of parsers, learners, features
