| # Inverted Index Dataset |
|
|
| This dataset contains the **inverted index** part of the manuscript. |
| The original data was stored as JSON files and has been **compressed into a ZIP archive** for upload and distribution. |
|
|
| The inverted index maps **words** (obtained by tokenizing chart descriptions) to the **images in which they appear** and the **frequency of occurrence** in each image. |
|

|
| ## Data Format |
|
|
| Each JSON file stores an inverted index with the following logical structure: |
|
|
| * **Word** |
| * **Specific image location** (relative image path) |
| * **Frequency** (number of times the word appears in that image) |
|
|
| Conceptually, the structure can be represented as: |
|
|
| ```json |
| { |
| "<word_1>": { |
| "<image_location_1>": <frequency>, |
| "<image_location_2>": <frequency> |
| }, |
| "<word_2>": { |
| "<image_location_3>": <frequency> |
| } |
| } |
