| # MBDef: media-bias definitions from the scientific literature |
|
|
| > **Version 1.0.0.** [Paper](https://arxiv.org/abs/XXXX.XXXXX) · [Code](https://github.com/XXXX/XXXX) · [MBDef Explorer](https://media-bias-group.github.io/MBDef/) · [Project page](https://media-bias-group.github.io/MBDef-ProjectPage/) · [MBDef-Gold](https://huggingface.co/datasets/mediabiasgroup/MBDef-Gold) |
|
|
| Researchers write about media bias and the concepts around it (framing, gatekeeping, hostile media effect, fake news, stance and many more), and they define these terms differently. MBDef collects those definitions as the papers state them, so that the field's vocabulary can be compared and organised into a taxonomy. |
|
|
| It holds **34,916 terms with 103,476 definitions from 6,115 papers**. The [MBDef Explorer](https://media-bias-group.github.io/MBDef/) shows it as a web page. The hand-labelled ground truth is a dataset of its own, [MBDef-Gold](https://huggingface.co/datasets/mediabiasgroup/MBDef-Gold). |
| The folder `explorer/` holds the Explorer's page data (150 files, listed with their SHA-256 in `explorer/SHA256SUMS`). It holds exactly the rows of these tables, and besides what they hold it gives every term-in-paper row a place on the map, a topic and its nearest rows, all computed on these rows alone. |
|
|
| ## The tables |
|
|
| Start with `terms`: one row per term with everything the papers say about it. The other four tables hold the rows it is built from and share ids, so any merged item can be traced to the papers that state it. |
|
|
| | Table | One row is | Rows | |
| |---|---|---:| |
| | `terms` | a term with all its definitions, description, synonyms, related terms, subtypes, supertypes and examples, merged across papers | 34,916 | |
| | `concepts` | a term: every term-in-paper whose label is the same up to spelling | 34,916 | |
| | `instances` | a term as one paper defines it ("term-in-paper"), with its relevance scores | 62,066 | |
| | `definitions` | one definition text, quoted from its paper | 103,476 | |
| | `papers` | a source paper: DOI, title, year, open-access status, licence | 6,115 | |
|
|
| Every term-in-paper that the relevance filter keeps is included. 50,037 of them also pass a stricter cut (the column `strict`; the paper says how the cuts were set). |
|
|
| ```python |
| from datasets import load_dataset |
| |
| terms = load_dataset("mediabiasgroup/MBDef", "terms", split="corpus") # start here |
| concepts = load_dataset("mediabiasgroup/MBDef", "concepts", split="corpus") |
| instances = load_dataset("mediabiasgroup/MBDef", "instances", split="corpus") |
| definitions = load_dataset("mediabiasgroup/MBDef", "definitions", split="corpus") |
| papers = load_dataset("mediabiasgroup/MBDef", "papers", split="corpus") |
| ``` |

| ## Read more |
|
|
| Each page covers one thing; the [paper](https://arxiv.org/abs/XXXX.XXXXX) has the details. |

|
| | Page | What it answers | |
| |---|---| |
| | [What one row is](https://huggingface.co/datasets/mediabiasgroup/MBDef/blob/main/docs/tables.md) | What the five tables hold, with a worked example | |
| | [Columns](https://huggingface.co/datasets/mediabiasgroup/MBDef/blob/main/docs/columns.md) | What every column means | |
| | [How it was made](https://huggingface.co/datasets/mediabiasgroup/MBDef/blob/main/docs/how-it-was-made.md) | The five steps, from the literature search to the kept terms | |
| | [Which terms are kept](https://huggingface.co/datasets/mediabiasgroup/MBDef/blob/main/docs/relevance.md) | How a term-in-paper is scored and kept or dropped | |
| | [Term merging](https://huggingface.co/datasets/mediabiasgroup/MBDef/blob/main/docs/term-merging.md) | How spellings become one term, and how to trace a merge | |
| | [The terms view](https://huggingface.co/datasets/mediabiasgroup/MBDef/blob/main/docs/terms-view.md) | The merged items of `terms` and the other extracted fields | |

|
| ## Limits |
|
|
| - **No person has checked the corpus terms yet.** The filter keeps 92.1% of them. |
| - **Definitions are machine-extracted.** The filter judges the term, not each text. |
|
|
| The paper has the evaluation and the full limits. |
