-### Dataset Summary
-
-BEIR is a heterogeneous benchmark that has been built from 18 diverse datasets representing 9 information retrieval tasks:
-
-- Fact-checking: [FEVER](http://fever.ai), [Climate-FEVER](http://climatefever.ai), [SciFact](https://github.com/allenai/scifact)
-- Question-Answering: [NQ](https://ai.google.com/research/NaturalQuestions), [HotpotQA](https://hotpotqa.github.io), [FiQA-2018](https://sites.google.com/view/fiqa/)

-- Tweet Retrieval: [Signal-1M](https://research.signal-ai.com/datasets/signal1m-tweetir.html)
-- Entity Retrieval: [DBPedia](https://github.com/iai-group/DBpedia-Entity/)
-
-All these datasets have been preprocessed and can be used for your experiments.
-
-
-```python
-
-```
-
-### Supported Tasks and Leaderboards
-
-The dataset supports a leaderboard that evaluates models against task-specific metrics such as F1 or EM, as well as their ability to retrieve supporting information from Wikipedia.
-
-The current best performing models can be found [here](https://eval.ai/web/challenges/challenge-page/689/leaderboard/).
-
-### Languages
-
-All tasks are in English (`en`).
-
-## Dataset Structure
-
-All BEIR datasets must contain a corpus, queries and qrels (relevance judgments file). They must be in the following format:
-- `corpus` file: a `.jsonl` file (jsonlines) that contains a list of dictionaries, each with three fields `_id` with unique document identifier, `title` with document title (optional) and `text` with document paragraph or passage. For example: `{"_id": "doc1", "title": "Albert Einstein", "text": "Albert Einstein was a German-born...."}`
-- `queries` file: a `.jsonl` file (jsonlines) that contains a list of dictionaries, each with two fields `_id` with unique query identifier and `text` with query text. For example: `{"_id": "q1", "text": "Who developed the mass-energy equivalence formula?"}`
-- `qrels` file: a `.tsv` file (tab-seperated) that contains three columns, i.e. the `query-id`, `corpus-id` and `score` in this order. Keep 1st row as header. For example: `q1 doc1 1`
-
-### Data Instances
-
-A high level example of any beir dataset:
-
-```python
-corpus = {
-    "doc1" : {
-        "title": "Albert Einstein", 
-        "text": "Albert Einstein was a German-born theoretical physicist. who developed the theory of relativity, \
-                 one of the two pillars of modern physics (alongside quantum mechanics). His work is also known for \
-                 its influence on the philosophy of science. He is best known to the general public for his mass–energy \
-                 equivalence formula E = mc2, which has been dubbed 'the world's most famous equation'. He received the 1921 \
-                 Nobel Prize in Physics 'for his services to theoretical physics, and especially for his discovery of the law \
-                 of the photoelectric effect', a pivotal step in the development of quantum theory."
-        },
-    "doc2" : {
-        "title": "", # Keep title an empty string if not present
-        "text": "Wheat beer is a top-fermented beer which is brewed with a large proportion of wheat relative to the amount of \
-                 malted barley. The two main varieties are German Weißbier and Belgian witbier; other types include Lambic (made\
-                 with wild yeast), Berliner Weisse (a cloudy, sour beer), and Gose (a sour, salty beer)."
-    },
-}
-
-queries = {
-    "q1" : "Who developed the mass-energy equivalence formula?",
-    "q2" : "Which beer is brewed with a large proportion of wheat?"
-}
-
-qrels = {
-    "q1" : {"doc1": 1},
-    "q2" : {"doc2": 1},
-}
-```
-
-### Data Fields
-
-Examples from all configurations have the following features:
-
-### Corpus
-- `corpus`: a `dict` feature representing the document title and passage text, made up of:
-    - `_id`: a `string` feature representing the unique document id
-        - `title`: a `string` feature, denoting the title of the document.
-        - `text`: a `string` feature, denoting the text of the document.
-
-### Queries
-- `queries`: a `dict` feature representing the query, made up of:
-    - `_id`: a `string` feature representing the unique query id
-    - `text`: a `string` feature, denoting the text of the query.
-
-### Qrels
-- `qrels`: a `dict` feature representing the query document relevance judgements, made up of:
-    - `_id`: a `string` feature representing the query id
-        - `_id`: a `string` feature, denoting the document id.
-        - `score`: a `int32` feature, denoting the relevance judgement between query and document.

+### Data Fields
+
+Examples from all configurations have the following features:
+
+### Corpus
+- `corpus`: a `dict` feature representing the document title and passage text, made up of:
+    - `_id`: a `string` feature representing the unique document id
+        - `title`: a `string` feature, denoting the title of the document.
+        - `text`: a `string` feature, denoting the text of the document.
+
+### Queries
+- `queries`: a `dict` feature representing the query, made up of:
+    - `_id`: a `string` feature representing the unique query id
+    - `text`: a `string` feature, denoting the text of the query.
+
+### Qrels
+- `qrels`: a `dict` feature representing the query document relevance judgements, made up of:
+    - `_id`: a `string` feature representing the query id
+        - `_id`: a `string` feature, denoting the document id.
+        - `score`: a `int32` feature, denoting the relevance judgement between query and document.
