OSIRRC Docker Image for Entity Retrieval

Negar Arabzadeh

This is the docker image for the Entity Retrieval conforming to the OSIRRC jig for the Open-Source IR Replicability Challenge (OSIRRC) at SIGIR 2019. This image is available on Docker Hub. The OSIRRC 2019 image library contains a log of successful executions of this image.

• Supported hooks: init, index, search

Quick Start

This docker runs the entity retrieval task :

The following jig command can be used to install the requirements packages and index DBPedia URIs:

Pass a dummy collection, this collection is not used in this docker :

python3 run.py prepare \
    --repo osirrc2019/entityretrieval \
    --collections robust04=path/to/robust004=trecweb 

The following jig command can be used to perform an entity retrieval run:

python run.py search \
  --repo osirrc2019/entityretrieval \
  --output out/entityretrieval \
  --qrels qrels/qrels.robust04.txt \
  --topic topics/topics.robust04.txt \
  --collection robust04 \
  --opts model=sdm_elr threshold=0.1 nfields=10 lambdas=0.1,0.05,0.05,0.8

The output file will show up under the follwing file name format:

[Model][nfields]_th[threshold]_Lambda[lambdaE]_[lambdaU]_[lambdaO]_[LambdaT].treceval

For instance with the mentioned retrieval, the output would be : edm_elr10_th0.1_0.1_0.05_0.05_0.8

The arguments model[required], threshold[optional], nfields[optional] and lambdas[required for some models] can be customized. Acceptable values for the customized arguments are:

• model:

- "lm"[2]
- "mlm-tc"[3]
- "mlm-all"[4] 
- "prms"[5]
- "sdm" [6]
- "fsdm"[7]
- "lm_elr"[1]
- "mlm_elr"[1]
- "mlm-tc_elr"[1]
- "prms_elr"[1]
- "sdm_elr"[1]
- "fsdm_elr"[1]      

• threshold: Entity linking threshold which is a float number, default=0.1

• nfields Number of fields which is an integer number, default=10

• lambdas comma separated values for lambdas mentioned in the paper e.g, lambdaE,lambdaU,lambdaO,LambdaT which are float numbers and lambdaE+ lambdaU+ lambdaO+ LambdaT =1 .
