+# ConTEB - ESG Reports
+
+This dataset is part of *ConTEB* (Context-aware Text Embedding Benchmark), designed for evaluating contextual embedding model capabilities. It focuses on the theme of **Industrial ESG Reports**, particularly stemming from the fast-food industry.
+
+## Dataset Summary
+
+This dataset was designed to elicit contextual information. It is built upon [a subset of the ViDoRe Benchmark](https://huggingface.co/datasets/vidore/esg_reports_human_labeled_v2). To build the corpus, we start from the pre-existing collection of ESG Reports, extract the text, and chunk them (using [LangChain](https://github.com/langchain-ai/langchain)'s RecursiveCharacterSplitter with a threshold of 1000 characters). We then manually re-annotate the queries to ensure that they are linked to the relevant chunk of the annotated original page. Queries were manually crafted in the original dataset.
+
+This dataset provides a focused benchmark for contextualized embeddings. It includes a curated set of original documents, chunks stemming from them, and queries.
+
+*   **Number of Documents:** 30 
+*   **Number of Chunks:** 3702 
+*   **Number of Queries:** 36 
+*   **Average Number of Tokens per Doc:** 205.5 
+
+## Dataset Structure (Hugging Face Datasets)
+The dataset is structured into the following columns:
+
+*   **`documents`**: Contains chunk information:
+    *   `"chunk_id"`:  The ID of the chunk, of the form `doc-id_chunk-id`, where `doc-id` is the ID of the original document and `chunk-id` is the position of the chunk within that document. 
+    *   `"chunk"`:  The text of the chunk
+*   **`queries`**: Contains query information:
+    *   `"query"`: The text of the query.
+    *   `"answer"`: The answer relevant to the query, from the original dataset.
+    *   `"chunk_ids"`: A list of chunk IDs that are relevant to the query. This is used to link the query to the relevant chunks in the `documents` dataset.
