TencentGR-1M Dataset

TAAC2025 Preliminary Round Dataset(2025年腾讯广告算法大赛初赛数据集) TencentGR-1M Dataset is a large-scale, all-modality dataset designed specifically for generative recommendation (GR) in industrial advertising. Constructed from real, de-identified Tencent Ads logs, it aims to address the lack of realistic, public multi-modal datasets in the GR field.

• Data Features: Contains rich collaborative IDs and multi-modal representations (text and vision) extracted using state-of-the-art embedding models.
• Dataset Size: Provides 1 million user sequences, with each user sequence containing up to 100 interacted items.
• Labels: Each interaction within the sequence is explicitly labeled with exposure(0) and click(1) signals.

Data Format

All data files are stored in Snappy-compressed Parquet format.

Schema

For clarity and brevity, we provide detailed schema descriptions for each table below.

Need to notice that we use two types of IDs in the dataset: the original IDs and the remapped IDs, for simplicity, we will denote them as OID and RID. OIDs are used in mm_emb, and RIDs are used in all the training data and can be used for building models. The mapping between OIDs and RIDs can be found in the indexer.pkl file.

item_feat

The item_feat table contains the features of each item appeared in the seq set.

Field	Type	Description	# Non-None Values
item_id	int64	RID for each item.	4783154

The seq table contains the behavior sequence for each user.

Field	Type	Description	# Non-None Values
user_id	int64	RID for each user.	1001845
seq	List[Dict]	The behavior sequence for each user, each dict contains 3 keys: item_id(RID), action_type, and timestamp, where the values are all integers	1001845

candidate

The candidate table contains the candidate items for the competition.

Note:

• This candidate is for the competition, but we do not provide the ground truth labels. People may refer to this format to build their own candidate set.
• The candidate contains some items that are not in the seq.

Field	Type	Description	# Non-None Values

indexer.pkl

This is a remapping file that maps the original IDs/Values to the remapped IDs/Values. The format is a dictionary with the following structure:

{
    "u": 
        { 
            OID: RID, 
            ... 
        },
    "i": 
        { 
            OID: RID, 
            ... 
        },
    "f":
        {
            101: 
                {
                    10100000000: 1, // original value: remapped value
                    10100000001: 2, 
                    ...
                },
            102:

            ...
