DIMwid

DIMwid (Decoder Inspection for Moses using widgets) is a tool presenting Moses' different chart/stack outputs in a readable tabular view.

Installation

In order to run DIMwid you need to install PyQt, Qt 4.8 and Python 2.7. Other versions have not yet been tested. Linux/Unix users simply install these packages using their package-manager or built them from source. Windows can skip the installation of Qt since PyQt itself does cover everything, except Python.

Usage

Users are recommended to read the accompanying paper "DIMwid -- Decoder Inspection for Moses (using Widgets)" appearing in PBML XY.

DIMwid is able to read multiple decoder outputs of the Moses translation system. These include the standard trace outputs for both phrase- and syntax-based decoding, the search-graphs for both, the "level 3 verbose" output for phrase-based and a special trace output (available as a Moses fork at : https://github.com/RobinQrtz/mosesdecoder) for all possible translations for syntax-based decoding.

After producing the outputs from Moses, start DIMwid by running DIMwid.py and first select your format and after that your file. If you have chosen the wrong file or format an error message will appear. Otherwise you will see the first sentence. Cells can be inspected by either double-clicking, opening a new window with the full content, or hovering over the cell, showing a tooltip with the first 20 lines of the cell's content.

If needed, the user can restrict the number of rules per cell, using the "Cell Limit" spinbox.

Navigating through the sentences of the input file can be done by either using the "Next" and "Prev" buttons, or choosing a certain sentence number using the lower left spinbox and clicking the "GoTo" button.

Moses

Information about Moses can be found here: http://statmt.org/moses/

The used flags for the output are: * -t for phrase-based trace * -T for syntax-based trace * -v 3 for phrase-based verbose level 3 * -output-search-graph for both search graphs * -Tall for the Moses fork's new feature
