WANDS is a Wayfair product search relevance dataset that is published as a companion to the paper from ECIR 2022:

WANDS: Dataset for Product Search Relevance Assessment
Yan Chen, Shujian Liu, Zheng Liu, Weiyi Sun, Linas Baltrunas and Benjamin Schroeder

The dataset allows objective benchmarking and evaluation of search engines on an E-Commerce dataset. Key features of this dataset includes:

1. 42,994 candidate products
2. 480 queries
3. 233,448 (query,product) relevance judgements

Please refer to the paper for more details.

To get a local copy up and running follow these simple steps.

Clone the repo

git clone https://github.com/wayfair/WANDS.git

The data is stored in the dataset folder in three files:

1. product.csv - Stores all candidate products, columns include:
   a. product_id - ID of a product
   b. product_name - String of product name
   c. product_class - Category which product falls under
   d. category_hierarchy - Parent categories of product, delimited by /
   e. product_description - String description of product
   f. product_features - | delimited string of attribute:value pairs which describe the product
   g. rating_count - Number of user ratings for product
   h. average_rating - Average rating the product received
   i. review_count - Number of user reviews for product

2. query.csv - Stores search queries, columns include:
   a. query_id - unique ID for each query
   b. query - query string
   c. query_class - category to which the query falls under

3. label.csv - Stores annotated (product,relevance judgement) pairs, columns include
   a. id - Unique ID for each annotation
   b. query_id - ID of the query this annotation is for
   c. product_id - ID of the product this annotation applies to
   d. label - Relevance label, one of 'Exact', 'Partial', or 'Irrelevant'

We have included a sample notebook read_dataset.ipynb to show you how you can read the data from the three CSV files easily.

We released annotation guidelines as a supplement to the dataset.
