Digital Tale of Genji - Feature Introduction.
We will explain the AI Image Search.
AI Image Search cross-searches manuscript images based on the Koigenji Monogatari,
finding pages with high text similarity across multiple manuscripts and printed editions.
It is useful for finding image data of specific scenes in the Tale of Genji.
The registration status shows searchable manuscripts and editions listed by chapter.
Let us explain how similarity is calculated.
First, text data is attached to each image using kuzushiji OCR.
Then, the text data is compared with the Koigenji Monogatari at the double-page spread level.
Results are displayed in order of highest similarity.
Here is how to access the search screen.
Access it from "AI Image Search Edition" in the menu.
Click the menu item on the left side.
Click the search button.
We will explain the search workflow.
Here are the steps to find image data of a specific scene.
Step 1: Find the page in the Koigenji Monogatari that corresponds to the scene.
Step 2: Select manuscript pages with high similarity.
Step 3: Compare with the Koigenji Monogatari to confirm the correct page.
Let us start with Step 1.
Search the text of the Koigenji Monogatari.
Enter a word from the scene. For example, "inuki."
You can narrow results by specifying a chapter.
Search results are displayed.
The Koigenji Monogatari image and text are shown.
Confirm whether this is the page of the scene you are looking for.
Here are some search tips.
Searches using different notation from the Koigenji Monogatari text will not produce hits.
For example, searching "犬君" in kanji won't work; use "いぬき" in hiragana instead.
Try switching between kanji and kana, with or without voiced marks.
Now, Step 2.
Select manuscript pages with high similarity scores.
Select the manuscript pages to compare.
