ir-datasets-longeval

💾 ir-datasets-longeval

Extension for accessing the LongEval datasets via ir_datasets.

Installation

Install the package from PyPI:

pip install ir-datasets-longeval

Usage

The ir_datasets_longeval extension provides an load method that returns a LongEval ir_dataset that allows to load official versions of the LongEval datasets as well as modified versions that you have on your local filesystem:

from ir_datasets_longeval import load

# load an official version of the LongEval dataset.
dataset = load("longeval-web/2022-06")

# load a local copy of a LongEval dataset.
# E.g., so that you can easily run your approach on modified data.
dataset = load("<PATH-TO-A-DIRECTORY-ON-YOUR-MACHINE>")

# From now on, you can use dataset as any ir_dataset

LongEval datasets have a set of temporal specifics that you can use:

# At what time does/did a dataset take place?
dataset.get_timestamp()

# Each dataset can have a list of zero or more past datasets/interactions.
# You can incorporate them in your retrieval system:
for past_dataset in dataset.get_prior_datasets():
    # `past_dataset` is an LongEval `ir_dataset` with the same functionality as the `dataset`
    past_dataset.get_timestamp()

If you want to use the CLI, just use the ir_datasets_longeval instead of ir_datasets. All CLI commands will work as usual, e.g., to list the officially available datasets:

ir_datasets_longeval list
