Projecting RMRS from TIGER Dependencies
نویسندگان
چکیده
We present a method for automatic RMRS semantics construction from dependency structures, following the semantic algebra of Copestake et al. (2001). We have applied this method to a subset of the TIGER Dependency Bank for German (Forst et al., 2004) to obtain a semantic treebank for (HPSG) parser evaluation. We describe the semantics construction mechanism and give evaluation figures from manual validation of the treebank. These indicate high precision of the automatic RMRS construction process.

The TIGER 700 RMRS Bank: RMRS Construction from Dependencies
We present a treebank conversion method by which we construct an RMRS bank for HPSG parser evaluation from the TIGER Dependency Bank. Our method effectively performs automatic RMRS semantics construction from functional dependencies, following the semantic algebra of (Copestake et al., 2001). We present the semantics construction mechanism, and focus on some special phenomena. Automatic convers...
متن کاملTiger 700
This paper documents the TIGER 700 RMRS Treebank which has been obtained as the result of a software project. The treebank is a semantic projection from a subset of the TIGER Dependency Bank and was derived automatically, using treebank conversion methods. In a second phase, it will be manually validated and corrections will be made as necessary, supported by an interactive editing tool.
متن کاملAcquiring Ontological Relationships from Wikipedia Using RMRS
We investigate the extraction of ontologies from biological text using a semantic representation derived from a robust parser. The use of a semantic representation avoids the problems that traditional pattern-based approaches have with complex syntactic constructions and long-distance dependencies. The discovery of taxonomic relationships is explored in a corpus consisting of 12,200 animal-rela...
متن کاملDiscosuite - A parser test suite for German discontinuous structures
Parser evaluation traditionally relies on evaluation metrics which deliver a single aggregate score over all sentences in the parser output, such as PARSEVAL. However, for the evaluation of parser performance concerning a particular phenomenon, a test suite of sentences is needed in which this phenomenon has been identified. In recent years, the parsing of discontinuous structures has received ...
متن کاملDependency and (R)MRS
Note: for current purposes, this document lacks a proper introduction, in that it assumes readers know about MRS and RMRS. The MRS and RMRS languages are successful in allowing grammar writers to construct underspecified compositional semantics for a variety of languages. They can be used with feature structure formalisms, but also in a separate semantic module with other styles of syntax. RMRS...
