OVERVIEW
|
| 28 |
+
--------
|
| 29 |
+
A fine-tuned DictaBERT + CRF model for Named Entity Recognition of recipe
|
| 30 |
+
modifications in Hebrew YouTube cooking comments. The model identifies spans
|
| 31 |
+
where commenters describe substitutions, quantity changes, technique changes,
|
| 32 |
+
and additions to recipes. This checkpoint (P10) is the best-performing
|
| 33 |
+
configuration in a progressive training series evaluated against both human-
|
| 34 |
+
annotated gold examples and silver-labeled data.

MODEL ARCHITECTURE
|
| 68 |
+
--------------------------------------------------------------------------------
|
| 69 |
+
Base encoder : DictaBERT (Hebrew BERT trained by the Dicta Institute)
|
| 70 |
+
Decoder : Conditional Random Field (CRF) layer
|
| 71 |
+
Tagging scheme: IO (no B- prefix; spans are contiguous I- sequences)
|
| 72 |
+
Training data : processed/train_merged.jsonl from the companion dataset repo
|
| 73 |
+
(thread-aware tokenization, merged silver + guided splits)
|
| 74 |

LABEL SCHEMA
|
| 77 |
+
--------------------------------------------------------------------------------
|
| 78 |
+
O Not a recipe modification span
|
| 79 |
+
I-SUBSTITUTION Ingredient or component substitution
|
| 80 |
+
I-QUANTITY Quantity or measurement change
|
| 81 |
+
I-TECHNIQUE Cooking technique change
|
| 82 |
+
I-ADDITION Addition of a new ingredient or step

USAGE NOTES
|
| 98 |
+
--------------------------------------------------------------------------------
|
| 99 |
+
• Load best_model.pt with a DictaBERT + CRF inference wrapper.
|
| 100 |
+
• Use id2label.json / label2id.json to map model outputs to span types.
|
| 101 |
+
• Input text should be tokenized consistently with the DictaBERT tokenizer
|
| 102 |
+
used during training (see training_summary.json for tokenizer details).
|
| 103 |
+
• The model was developed for naturally occurring Hebrew cooking discourse;
|
| 104 |
+
performance on formal recipe text may differ.
