Evaluation

We provide three scripts for evaluation.

Graph Evaluation

This calculates precision, recall, and F-score over edges.

python3 tools/evaluation/graph-eval.py --gold gold-files --auto system-files

The expected format for output files is:

anything.../filename:line-number line-number -

For example:

blah-blah/2004-11-15.annotation.txt:1000 1000 -
blah-blah/2004-11-15.annotation.txt:1001 1001 -
blah-blah/2004-11-15.annotation.txt:1002 1002 -
blah-blah/2004-11-15.annotation.txt:1003 1002 -
yaddah_yaddah/2004-11-15.annotation.txt:1004 1003 -
yaddah_yaddah/2004-11-15.annotation.txt:1005 1003 -

Conversation Evaluation

This calculates a range of cluster metrics. It requires the Google OR Tools.

python3 tools/evaluation/conversation-eval.py gold-file system-file

The expected format for output files has each cluster on one line:

anything.../filename:line-number line-number line-number line-number ...

For example:

blah-blah/2004-11-15.annotation.txt:1000
blah-blah/2004-11-15.annotation.txt:1001
yaddah_yaddah/2004-11-15.annotation.txt:1002 1003 1004 1005

It also has the option to specify the set of metrics to use.

DSTC 8 Evaluation

This is the code being used in DSTC 8. It is run with:

python3 tools/evaluation/dstc8-evaluation.py --gold data/dev/*anno* --auto example-run.out

For a model trained as described in the source code README, that should give:

92.15   1 - Scaled VI
74.19   Adjusted rand index
40.53   Matched clusters precision
41.26   Matched clusters recall
40.89   Matched clusters f-score

The expected format is the same as for graph-eval.py

Annotator Agreement

This is the code we used to calculate agreement between annotators. It expects to receive a list of filenames as arguments, where files are named:

DATA.annotation.ANNOTATOR

Results are printed for each pair of annotators.

Significance Testing

This uses a permutation test, comparing two sets of annotations. It is run with:

./tools/evaluation/significance.py \
  gold-file
  --auto0 system0-output-files
  --auto system1-output-files

Format Conversion

These are a set of tools for converting annotations:

Tool Purpose
output-from-py-to-graph.py Convert the output of the model into our graph format.
graph-to-cluster.py Convert a set of links into a set of conversations with Union-Find.
cluster-to-messages.py Print out the actual messages that a set of conversations correspond to.
graph-to-messages.py Do both graph-to-cluster and cluster-to-message at once.
output-from-cpp-to-graph.py Convert the output of the C++ model into our graph format.

Preprocessing

Download IRC data

./download-raw-data.sh will download all available IRC data from the Ubuntu channel. Note, this includes some days in which there is no data or the files have other issues.

Convert to ASCII

We converted downloaded files to ascii in two steps:

  1. Run make-txt.py to convert as much as possible (this will handle most cases of things like accents).
  2. Use tr -cd '[:print:]\\n\\t' < filename > filename.ascii to delete remaining non-ascii characters.

Tokenise

We have two tokenisation scripts (preliminary experiments with off-the-shelf tokenisers gave poor results). The easiest one to run is the one we’ve prepared for DSTC 8:

./dstc8-tokenise.py --vocab vocab.txt --output-suffix .tok ASCII-FILENAME

The other (tokenise.py) has additional options that are generaly not needed.

Run to convert text to tokens with unk symbols.
