RmrsDmrsComparison Tool

Cambridge University Computer Laboratory MPhil in Computer Speech Text and Internet Technology (CSTIT) Individual Project

A DMRS comparison tool developed as part of the DELPH-IN tool kit

The ‘RmrsDmrsComparison’ tool operates on DMRS syntactic representation of sentences in XML format and stores them in memory using efficient data structures. These files contain many sentences each with many associated parses. The tool has five different usages triggered by different command line arguments.

The packing and unpacking tool output the internal representation to an XML file in packed and unpacked DMRS representations respectively. The structural comparison function takes two sets of DMRS sentences and identifies which sentences are the same, different or partially match. Structural similarity identification compares two parses for common nodes and links and finally the duplicate node and link identification tool finds duplicate nodes and links within a parse.

An overview of related software and specifications can be found at the DELPH-IN home page and wiki.

Full implementation details and explanation of the packed DMRS framework and related functions can be found in thesis.pdf in the downloads section of this site.

A brief overview of the tool can be found in the online usage documentation.
