TREC 2024 RAG Track Guidelines

Version 1.0. Last Updated: July 19, 2024

Participating teams will receive both the MS MARCO V2.1 document & segment collection and a list of topic descriptions. For each topic, participants have the choice to participate in either all or any of three tasks introduced this RAG this year. For the Retrieval Track (R), participating systems would provide a ranked list of segment IDs retrieved from the MS MARCO V2.1 segment collection. Next, for tracks with Augmented Generation (AG & RAG), participating systems would generate an answer description (containing upto a maximum of 400 words) broken into individual sentences with citations from the MS MARCO V2.1 segment collection.

Participate in our RAG Track by registering for TREC at this website. Test topics will be released by August 11, 2024 & submit your participating runs by August 25, 2024 (AOE)!

Task Overview

We are excited to provide details on each task which will be conducted in the first year of the TREC RAG track! You can participate in any or all of the three tasks below:

TREC 2024 RAG Task	Input	Output
(R) Retrieval Task	MS MARCO V2.1 Segment Collection + List of Topics	Ranked List of Segment IDs drawn from the collection
(AG) Augmented Generation Task	Ranked List of Segment IDs + List of Topics	RAG Answer with references from provided Segment IDs
(RAG) Retrieval-Augmented Generation Task	MS MARCO V2.1 Segment & Document Collection + List of Topics	RAG Answer with references from provided Segment IDs

Assessment & Evaluation

Evaluation of the participating systems will involve four metrics: Nugget evaluation, Support evaluation, Fluency evaluation & Retrieval evaluation. All cited segments provided by the partcipants will be added to the relevance assessment pools for each individual topic. After the first round of LLM-generated relevance assessments with post-curation from NIST assessors, the LLM-generated nugget list for nugget evaluation with post-curation from NIST assessors. Finally, we assign scores based on nugget recall and precision and other factors involving LLM-assisted support evaluation (grouding based on referenced segments) and LLM-assisted fluency evaluation (grammar and coherence) of the RAG response with post-curation from NIST assessors. The detailed process for assessment will be outlined soon.

Tasks Overview

Retrieval Task (R)

The retrieval task as the name suggets is an ad-hoc information retrieval task similar to the previous TREC Deep Learning Track. Participating systems will receive a list of topics and the MS MARCO V2.1 segment collection. For each topic, the system needs to return the TREC runfile containing the ranked list containing the top 20 relevant segment IDs from the collection. The topics provided will be non-factoid and require long-form answer generation.

The “R” track emulates the previous TREC-DL 2022/2023 tracks is for the IR audience, however, the main difference lies in using document chunks from the MS MARCO V2.1 segment collection instead of the MS MARCO v2.0 passage collection.

Input Format (Topics)

List of queries as topics as TSV: <trec_rag_2024_queries.tsv>, with each line containing the topic_id and a sentence-length description of the topic.

Output Format (Ranked Results)

Participants should provide their output in the standard TREC format containing top-k=100 MS MARCO v2.1 segments as TSV: <r_output_trec_rag_2024.tsv> for each individual topic. Each set of ranked results for a set of topics appears in a single file. We will take a maximum of 100 results from each participant, more than 100 results will be truncated. Note that our human judgment pools are likely not going to be more than 20 segments per query per run, having 100 helps us evaluate recall statistics. Each line of this file contains six whitespace-separated entries:

• Topic ID (topic identifier taken from trec_rag_2024_queries.tsv)
• The fixed string “Q0”
• Segment ID (from the docid field in msmarco_v2.1_doc_segmented_XX.json.gz)
• Rank (which is the rank of the segment retrieved)
• Score (integer or float that generated the ranking. This score must be in non-increasing order)
• Run ID (where you mention the ID of the run you are submitting, e.g., “rank_zephyr_best”)

Augmented Generation Task (AG)

The Augmented Generation task emulates the modern-day RAG task to return the summarized answer ground based on the information available in the pre-determined list of top-k segments provided to the participant. Participating systems will receive a list of topics, MS MARCO V2.1 segment collection and the ranked list of the top-k relevant segments for each individual topic. The topics provided will be non-factoid and require long-form answer generation.

The AG track is for the NLP audience, focused on the generation output and quality. We provide the top-k retrieved segments, which allows the participants to focus on the answer generation quality, by grounding on the set of chunks of segments, and generate an informative & summarized answer.

Input Format (Topics)

List of queries as topics as TSV: <trec_rag_2024_queries.tsv>, with each line containing the topic_id and a sentence-length description of the topic.

Input Format (Ranked Results)

Top-20/100 retrieved segments for each individual topic using our baseline retrieval system on the MS MARCO v2.1 segment collection: <baseline_r_out.tsv>. We will provide a maximum of 100 segments for each individual topic. This file has the same format as the output file for the retrieval task.

- Topic ID (taken from `trec_rag_2024_queries.tsv`)
- The fixed string “Q0”
- Segment ID (from the docid field in `msmarco_v2.1_doc_segmented_XX.json.gz`)
- Rank (which is the rank of the segment retrieved)
- Score (integer or float that generated the ranking. This score must be in descending, non-increasing order)
- Run ID (where you mention the ID of the run you are submitting, e.g., "rank_zephyr_best")

We will additionally provide reranker requests JSONL file, , described at the end of the section [here](https://github.com/castorini/ragnarok/blob/main/docs/rag24.md#retrieval---bm25), where each line is a JSON object with the following fields:

{

        },
        {
            ...
        }
    ]
}

Providing the url, title, headings, segment, start_char, and end_char fields for each candidate segment will help participants with limitations in downloading the entire MS MARCO v2.1 segment collection, to still get to participate in the AG task.

Output Format (AG Output)

Participants should provide their output in the standard JSONL format containing the following JSON information as <ag_output_trec_rag_2024.jsonl> for each individual topic. The final RAG answer should provided in the following JSON format. Each line of this JSONL file contains the following entries:

• run_id (string) containing the run tag to your submission (e.g. “h2oloo-ragnarok-baseline”)
• topic_id (string) from the topic_id taken from trec_rag_2024_queries.tsv
• topic (string) the sentence-level description of the topic taken from trec_rag_2024_queries.tsv
• references (array) containing the ranked list of top-k segment IDs from the retrieval stage (a maximum of only 20 segments is allowed)
• response_length (integer) containing the total words present in the overall RAG response.
• answer (array) containing the list of sentences and citations from the references list. The text field contains the response and citations field contains the (zero-indexed) reference of the segment from the references list.

Retrieval-Augmented Generation Task (RAG)

• Given: Participants will be provided a list of topics and both the MS MARCO v2.1 document and MS MARCO v2.1 segment collections.
• Task: Return the summarized answer and ground based on information which you can either the MS MARCO v2.1 document or segment collection. Develop your own retrieval system to fetch relevant information from the MS MARCO v2.1 segment/document collection. You can use either our pre-determined segment collection or incorporate your own chunking technique with the MS MARCO v2.1 document collection. For evaluation, we ask each participant to map their chunk of segments with MS MARCO v2.1 segment collections.
• Notes: The RAG track is a mixture of above (R) and (AG) tracks. This setup mimics best the industrial RAG setup for the NLP+IR audience. We evaluate the summarized answer in multiple ways incorporating both grounding and evaluating fluency of the generated output.

Input Format (Topics)

List of queries as topics as TSV: <trec_rag_2024_queries.tsv>, with each line containing the topic_id and a sentence-length description of the topic.

There Are Some Guidelines To Follow\nby Kelly Mullen-McWilliams\nJuly 22, 2017\nI don\'t know about you, but I\'m personally super pumped for that perfect day in the admittedly far-off future when I throw that last diaper away — and then throw myself a party. If you\'re currently in the midst of toilet training, I salute you, and I also know you have a lot of questions. Whether it\'s going well or not, you\'re probably wondering things like, " how often should I take my toddler to the potty ?"\nMore Like This\nVaccinated People Can Ditch Masks. Where Does That Leave Kids?\n25 Real-Life Reasons Not To Trust Older Siblings Around The Baby\nMoms To Toddlers Everywhere: This Aggression Will Not Stand, Man\nHow 20 Kids Brought The Pandemic Into Their Play Worlds\nWhat Parents Are Talking About — Delivered Straight To Your Inbox\nSubscribe\nAccording to an article in Pediatrics, the official journal of the American Academy of Pediatrics (AAP), independent toilet use is a major milestone for your child, combining new physical capabilities with an understanding of social expectations, and their own motivation to become more autonomous. The article noted that toilet training is also one of the most difficult milestones for children and their parents, and that it can become highly emotional. Self-esteem can be fragile at this time, so it\'s important to toilet train gently, letting your child lead the way. Additionally, it\'s unwise to begin potty training unless your child is truly ready. Take this potty training readiness quiz featured in Parents before you begin.\nElizabeth Pantley, author of The No-Cry Potty Training Solution, explained in an excerpt on Child Development Info that most toddlers pee four to eight times per day. On top of that, toddlers have one or two bowel movements a day. But every toddler is an individual. Some will go more often than that, and others will last a couple days without having a bowel movement at all.\nIn terms of actually getting your toddler to the potty, Pantley suggested setting up a potty routine. Potty first thing in the morning, after eating, and before other activities, like riding in the car or going to sleep. Of course, you can adapt this routine to your lifestyle, and you still must be on the lookout for signs your toddler has to go ahead of schedule. If he or she looks squirmy, take them to the potty. But if you miss the signal, and there\'s a mess, it\'s no big deal. Practice makes perfect, after all. Don\'t let emotions get the better of you, even if your little girl or guy pees on an expensive piece of furniture.\nTry to get your toddler to the toilet frequently, but remember that it\'s OK if she needs a day off. According to Becoming the Parent You Want To Be by Laura Davis and Janis Keyser, it\'s common for children to go back and forth — somedays preferring diapers, and other days selecting to use the toilet. They recommended thinking of "accidents" as "opportunities."\nPantley also suggested visiting new restrooms when you\'re on the go. Frequent visits to toilets far and near may help habituate your child to independent toilet use. Keep in mind that not all children will want to use strange bathrooms, and don\'t force anything. Davis and Keyser stressed the importance of keeping your own emotions in check throughout the toilet training process.\nThe bottom line: when it comes to potty time, there\'s no magic number, but it\'s a good idea to take your toddler to the toilet often. Begin by following a schedule — morning pee, before nap time pee — and remember to look for signs that they\'re holding it. You can only take your child to the bathroom too much if it begins to feel stressful or punitive. If negative emotions attach themselves to toilet time, it\'s OK to take a break. It might take some time to achieve that no-more-diapers party, but that\'s fine. You\'ll just have that much longer to plan a good one.\nMay 27. 2021\nSEARCH CLOSE\nPregnancy\nSee All Trying Birth After\nRaising Kids\nSee All Baby Toddler Little Kid Big Kid\nYou\nSee All Sex & Relationships Wellness Style\nLife\nSee All Food Home Entertainment Politics Shopping\nHealth\nAbout Archive Terms Privacy Newsletter Archive Advertise Masthead Editorial Standards\n© 2021 Bustle Digital Group.
