 ## Dataset Details
 
 ### Dataset Description
 
-<!-- Provide a longer summary of what this dataset is. -->
-
+The QMUL-OpenLogo dataset is a large-scale logo detection benchmark designed for evaluating open logo detection algorithms in realistic deployment scenarios. Unlike traditional logo detection datasets that assume exhaustive fine-grained labeling for all classes, QMUL-OpenLogo simulates real-world conditions where new logo classes arrive progressively and require detection with little or no labeled training data.
 
+The dataset was created by aggregating and refining 7 existing logo detection datasets to establish a comprehensive benchmark for open logo detection. It contains 27,083 images across 352 logo classes, with a distinctive train/test split that designates only 32 classes as "supervised" (with labeled bounding boxes) while the remaining 320 classes are "unsupervised" (having only clean logo design images).

 ## Dataset Creation
 
 ### Curation Rationale
 
-<!-- Motivation for the creation of this dataset. -->
+The QMUL-OpenLogo dataset was created to address a significant gap in existing logo detection benchmarks. Traditional benchmarks assume artificial deployment scenarios where large training datasets with fine-grained bounding box annotations are available for each class. However, in realistic logo detection scenarios, new logo classes come progressively and require detection with little or no budget for exhaustively labeling training data.
 
-[More Information Needed]
+The dataset aims to provide a more realistic and challenging evaluation setting that better reflects real-world deployment constraints where scalability and adaptability to new classes are crucial.
 
 ### Source Data
 
-<!-- This section describes the source data (e.g. news text and headlines, social media posts, translated sentences, ...). -->
+The source data consists of images from 7 existing publicly available logo detection datasets, carefully merged and refined to create a cohesive benchmark.
 
 #### Data Collection and Processing
 
-<!-- This section describes the data collection and processing process such as data selection criteria, filtering and normalization methods, tools and libraries used, etc. -->
-
-[More Information Needed]
+**Source Dataset Integration**: The following datasets were aggregated:
+1. FlickrLogos-27 (27 classes, 810 images)
+2. FlickrLogos-32 (32 classes, 2,240 images) 
+3. Logo32plus (32 classes, 7,830 images)
+4. BelgaLogos (37 classes, 1,321 images)
+5. WebLogo-2M Test only (194 classes, 4,318 images)
+6. Logo-In-The-Wild (1,196 classes, 9,393 images)
+7. SportsLogo (20 classes, 1,978 images)
+
+**Class Refinement Process**:
+- Logo classes were made consistent across datasets (e.g., merging Adidas trefoil/text variations from LITW into single classes)
+- Erroneous annotations were cleaned (incorrect bounding box coordinates, size inconsistencies)
+- Classes with fewer than 10 images were removed to ensure sufficient test data
+- Manual verification of 1-3 random images per class was performed
+- Final result: 352 logo classes from 27,083 images
 
 #### Who are the source data producers?
 
-<!-- This section describes the people or systems who originally created the data. It should also include self-reported demographic or identity information for the source data creators if this information is available. -->
-
-[More Information Needed]
+The original data producers are the creators of the 7 source datasets, representing diverse research groups and data collection efforts. The QMUL team performed the aggregation, refinement, and standardization process to create the unified benchmark.
 
-### Annotations [optional]
+### Annotations
 
-<!-- If the dataset contains annotations which are not part of the initial data collection, use this section to describe them. -->

 #### Annotation process
 
-<!-- This section describes the annotation process such as annotation tools used in the process, the amount of data annotated, annotation guidelines provided to the annotators, interannotator statistics, annotation validation, etc. -->
+The annotation process involved:
+- **Integration**: Combining annotations from multiple source datasets with varying formats
+- **Standardization**: Making logo class definitions consistent across datasets
+- **Quality control**: Removing erroneous annotations and verifying class labels
+- **Clean-up**: Filtering out classes with insufficient data (<10 images)
+- **Validation**: Manual verification of sample images per class
 
-[More Information Needed]
+The annotations maintain the PASCAL VOC format for bounding boxes with class labels.
 
 #### Who are the annotators?
 
-<!-- This section describes the people or systems who created the annotations. -->
-
-[More Information Needed]
+The original annotations were created by the respective research teams for each source dataset. The QMUL team performed quality control, merging, and verification processes.
 
 #### Personal and Sensitive Information
 
-<!-- State whether the dataset contains data that might be considered personal, sensitive, or private (e.g., data that reveals addresses, uniquely identifiable names or aliases, racial or ethnic origins, sexual orientations, religious beliefs, political opinions, financial or health data, etc.). If efforts were made to anonymize the data, describe the anonymization process. -->
-
-[More Information Needed]
+The dataset primarily focuses on commercial logos and brand imagery collected from existing research datasets. Considerations include:
