FINN.no Slate Dataset for Recommender Systems

We release the FINN.no slate dataset to improve recommender systems
research. The dataset includes both search and recommendation
interactions between users and the platform over a 30 day period. The
dataset has logged both exposures and clicks, including interactions
where the user did not click on any of the items in the slate. To our
knowledge there exists no such large-scale dataset, and we hope this
contribution can help researchers constructing improved models and
improve offline evaluation metrics.

For each user u and interaction step t we recorded all items in the
visible slate
(up to the
scroll length ), and
the user’s click response
. The dataset
consists of 37.4 million interactions, |U| ≈ 2.3) million users and
|I| ≈ 1.3 million items that belong to one of G = 290 item groups. For
a detailed description of the data please see the
paper.

FINN.no is the leading marketplace in the Norwegian classifieds market
and provides users with a platform to buy and sell general merchandise,
cars, real estate, as well as house rentals and job offerings. For
questions, email [email protected] or file an issue.
Install
pip install recsys_slates_dataset
How to use
To download the generic numpy data files:
from recsys_slates_dataset import data_helper
data_helper.download_data_files(data_dir="data")

Download and prepare data into ready-to-use PyTorch dataloaders:
from recsys_slates_dataset import dataset_torch
ind2val, itemattr, dataloaders = dataset_torch.load_dataloaders(data_dir="data")

Organization
The repository is organized as follows: - The dataset is placed in
data/ and stored using git-lfs. We also provide an automatic download
function in the pip package (preferred usage). - The code open sourced
from the article “Dynamic Slate Recommendation with Gated Recurrent
Units and Thompson Sampling” is found
in (code_eide_et_al21/). However, we are in the process of making the
data more generally available which makes the code incompatible with the
current (newer) version of the data. Please use the v1.0 release of the
repository
for a compatible version of the code and dataset.
Quickstart dataset
We provide a quickstart Jupyter notebook that runs on Google Colab
(quickstart-finn-recsys-slate-data.ipynb) which includes all necessary
steps above. It gives a quick introduction to how to use the dataset.
Example training scripts
We provide an example training jupyter notebook that implements a matrix
factorization model with categorical loss that can be found in
examples/. It is also runnable using Google Colab:

There is ongoing work in progress to build additional examples and use
them as benchmarks for the dataset.
Dataset files
The dataset data.npz contains the following fields: - userId: The
unique identifier of the user. - click: The items the user clicked on in
each of the 20 presented slates. - click_idx: The index the clicked item
was on in each of the 20 presented slates. - slate_lengths: The length
of the 20 presented slates. - slate: All the items in each of the 20
presented slates. - interaction_type: The recommendation slate can be
the result of a search query (1), a recommendation (2) or can be
undefined (0).
The dataset itemattr.npz contains the categories ranging from 0 to
290. Corresponding with the 290 unique groups that the items belong to.
These 290 unique groups are constructed using a combination of
categorical information and the geographical location.
The dataset ind2val.json contains the mapping between the indices and
the values of the categories (e.g. "287": "JOB, Rogaland") and
interaction types (e.g. "1": "search").

Todo
This repository is currently work in progress, and we will provide
descriptions and tutorials. Suggestions and contributions to make the
material more available are welcome. There are some features of the
repository that we are working on:

Add more usable functions that compute relevant metrics such as
F1, counterfactual metrics etc.
The git lfs is currently broken by removing some lines in
.gitattributes that is in conflict with nbdev. The dataset is still
usable using the building download functions as they use a different
source. However, we should fix this. An issue is posted on
nbdev.
