*Introduction:*

The Product Search Track studies information retrieval in the field of product search. This is the case where there is a corpus of many products where the user goal and intent is to find the product that suits their need.

The main goal of the Trec Product Search Track is to study how end to end retrieval systems can be built and evaluated given a large set of products.

*Track Tasks:*

The product search track has three tasks: *ranking*, *end to end retrieval,* and* multi modal end to end retrieval*. You can submit up to three runs for each of these tasks.

Each track uses the same training data originating from the ESCI Challenge for Improving Product Search and shares the same set of evaluation queries.

Below the three tasks are described in more detail.

*Product Ranking Task*

The first task focuses on product ranking. In this task we provide an initial ranking of 1000 documents from a BM25 baseline and you are expected to re-rank the products in terms of their relevance to the users given intent.

The ranking provides a focused task where the candidate sets are fixed and there is no need to implement complex end to end systems which makes experimentation quick and runs easily comparable.

*Product Retrieval Task*

The second task focuses on end to end product retrieval. In this task we provide a large collection of products and participants need to design end to end retrieval systems which leverage whichever information they find relevant/useful.

Unlike the ranking task, the focus here is in understanding the interplay between retrieval and reranking systems.

*Multi-Modal Product Retrieval Task*

The third task focuses on end to end product retrieval using multiple modalities. In this task we provide a large collection of products where each product features additional attributes and information such as related clicks and images and participants need to design end to end retrieval systems which leverage whichever information they find relevant/useful.

The focus of this task is to understand the interplay between different modalities and the value which additional potentially weak data provides.
