Pre-requisites

In order to run the script you would need to:

* use python3.9,
* have python package Munkres installed (use `pip install munkres`).

Latest version

The latest version of the code is v2020.2.0 which can be found in branch: TYPEMETRIC-v2020.2.0.

How to run the scorer

The main scoring script is at: tools/scorer/score_submission.py.

Usage of the scorer

score_submission.py [-h] [-l LOG] [-r RUN] [-v] [-S {pretty,tab,space}] log_specifications gold system scores

Score RUFES output

positional arguments:
  log_specifications    File containing error specifications
  gold                  Input gold annotations file
  system                Input system response file
  scores                Output scores directory (note that this directory should not exist)

optional arguments:
  -h, --help            show this help message and exit
  -l LOG, --log LOG     Specify a file to which log output should be redirected (default: log.txt)
  -r RUN, --run RUN     Specify the run ID (default: runID)
  -v, --version         Print version number and exit
  -S {pretty,tab,space}, --separator {pretty,tab,space}
                        Column separator for scorer output? (default: pretty)

In order to run the scorer, you may use the following command:

cd tools/scorer
python3 score_submission.py -l logfile.txt -r yourRunID ../../input/log_specifications.txt /path/to/gold/annotations/file /path/to/system/output/file /path/to/scores/directory

How to run the scorer on a demo run

In order to run the scorer over the (included) demo run, you may use the following command:

python score_submission.py -l ../../input/demo/log.txt -r demo ../../input/log_specifications.txt ../../input/demo/gold.tab ../../input/demo/system_output.tab ../../input/demo/scores/

How to read the scorer output

The scorer produces the following scoring variants:

TypeMetricV1

This variant uses all the types asserted on the cluster as a set, and uses this set to compute Precision, Recall and F1.

The scores corresponding to this variant can be found in file: TypeMetricV1-scores.txt which contains the following columns:

• Column # 1: Document ID
• Column # 2: Run ID
• Column # 3: Gold Entity ID
• Column # 4: System Entity ID
• Column # 5: Precision
• Column # 6: Recall
• Column # 7: F1

TypeMetricV2

This variant of the scorer ranks the types asserted on the cluster, and computes AP where:

• ranking is induced using weights on types, and
• the weights on a type is the number of mentions asserting that type.

The scores corresponding to this variant can be found in file: TypeMetricV2-scores.txt which contains the following columns:

• Column # 1: Document ID
• Column # 2: Run ID
• Column # 3: Gold Entity ID
• Column # 4: System Entity ID
• Column # 5: Average Precision

TypeMetricV3

This variant of the scorer ranks the types asserted on the cluster, and computes AP where:

• ranking is induced using weights on types, and
• the weight on a type is computed as the sum of confidences on mentions asserting that type.

The scores corresponding to this variant can be found in file: TypeMetricV3-scores.txt which contains the following columns:

• Column # 1: Document ID
• Column # 2: Run ID
• Column # 3: Gold Entity ID
• Column # 4: System Entity ID
• Column # 5: Average Precision

How to read the log file

The log file produced by the scorer generates the following types of entries:

AP_INFO

This type of log entry contains information about the ranked list of types, their correctness, weights, and other information needed to compute AP.

ALIGNMENT_INFO

This log entry contains information about which gold-entity was aligned to which system-entity, and the corresponding alignment similarity which is the number of matching mentions.

SIMILARITY_INFO

This type of log entry contains the similarity information, and common mentions between a gold cluster, and a system cluster. This entry exists only if there is any similarity.

ENTITY_TYPES_INFO

This log entry contains information about gold or system entity types provided and the expanded types used for scoring.
