[Weekly Analysis] "AI Analysis" of YouTube Short Sign Language Videos

Hello, this is pakoha.
I have started learning sign language and am using YouTube to practice outputting. I started this hoping that many people would watch and point out any mistakes I might be making!

However, since I'm going to the trouble of posting videos, I decided to create a system that can analyze them objectively, and I would like to share the details here.
(It's going to be a rather long post, so I'll keep it brief💦)

GAS (Google Apps Script), Gemini API, and YouTube API are linked to have a report sent to me via email daily.

Here are the details of the last 5 videos↓

■ Detailed Analysis by AI:
### 1. Verification of Hashtags and Titles: Reaching the Audience Who Will Provide Feedback

Current hashtags are mostly "Sign language study," "Sign language learning," and "Beginner," which mainly reach people who have just started learning sign language or are looking for learning videos. This is slightly misaligned with the goal of "feedback from native speakers and experts."
* **Incorporate the perspective of the target audience (native speakers/experts)**
Native speakers and experts are interested in the "quality of sign language expression," "naturalness," and "cultural background," rather than just "learning videos."
* **Proposals for effective hashtags**
1. **Tags that clarify the purpose**:
#SignLanguageCorrectionRequested #SignLanguageFeedbackWanted #SignLanguageExpressionCheck #SignLanguageAdvice #SpotTheSignLanguageMistake These tags clearly indicate that you are "seeking feedback" and attract viewers who are willing to provide pointers.
2. **Tags that increase professionalism**:
#JapaneseSignLanguage (Required) #JSL #SignLanguageInterpretation #Deaf #HardOfHearing #SignLanguageCulture #SignLanguageTechnique These tags are more likely to be searched by people with more specialized knowledge.
3. **Tags that indicate specific content**:
The current "Shinkansen" and "Hakata" are good, but tag even more specific expressions and contexts.
Example: #DailyConversationSignLanguage #EmotionalExpressionSignLanguage #BusinessSignLanguage #[Today's Theme]SignLanguage
4. **Review existing tags**: Keep #Beginner while balancing it with the tags above.

* **Proposals for effective titles**
Change from the current "[Shinkansen] #DailyLife in Sign Language!" to a title that is more question-oriented and specific.
1. **Question-oriented**: "[XX] Is this sign language expression natural? #FeedbackWanted"
2. **Challenge-declaration type**: "[XX] Challenge! Does this expression get the point across? #SignLanguageCorrectionRequested"
3. **Specific theme and question**: "[Shinkansen] Conversation inside the train, is this Japanese Sign Language correct?"
4. **Utilize emojis**: "[Hakata Ramen] Expressing in sign language! Is it correct?"
By clearly stating in the title that you are "seeking feedback," you draw the viewers' attention.
### 2. Ways to Induce Feedback: Presentation that makes people want to teach you

Specific ingenuity is needed so that viewers feel, "I want to teach this person."

* **Clear expression of intent at the beginning of the video**
Within the first 10 seconds of the video, clearly call out with audio (or subtitles) and sign language: "I expressed today's theme, XX, in Japanese Sign Language. To all native speakers and experts, if there are any unnatural points in my sign language expression or if there is a better way to express it, please let me know in the comments!" This gives viewers the feeling that they have permission to point things out.
* **Utilization of the summary section (description)**

1. **Re-stating the purpose**: "I am practicing outputting Japanese Sign Language. I am especially looking forward to feedback from Deaf people and sign language experts."
2. **Examples of specific feedback formats**: "'The expression for XX is more natural as YY,' 'In this context, the expression ZZ would be better,' etc. Any small detail is fine. Please lend me your knowledge."
3. **Gratitude**: "Your feedback is an invaluable asset to my sign language learning. I thank you from the bottom of my heart."
A detailed description conveys your serious learning attitude and lowers the hurdle for providing feedback.
* **Ingenuity in video content and presentation**

1. **"Spot the mistake" format**: Intentionally mix in one slightly unnatural expression and ask, "Where is it wrong?" This makes it easier for viewers to participate like a game.
2. **Presenting multiple expressions**: By presenting options like, "Between A and B, which expression is more natural for this word?", it becomes easier to comment.
3. **Utilization of community posts**: Link with short videos and post images like, "Is this sign language for this word correct? I want to hear your opinions!" to encourage discussion in the comments.
4. **Awareness of facial expressions and fingerspelling**: Instead of aiming for perfection, showing human-like weaknesses such as "a face that looks a bit unsure" or "pretending to stumble on fingerspelling" creates a sense of familiarity and induces a desire to help.
### 3. Maximizing Learning Efficiency: A cycle of "applying feedback to the next step"

Build a cycle that maximizes the feedback you've received for learning and further induces the next round of feedback.

* **Recording and analyzing feedback**

Use Google Sheets or Notion to record the feedback received for each video.
1. **Content**: What kind of feedback was received (e.g., vocabulary, grammar, spatial use, facial expressions, fingerspelling, etc.).
2. **Specific examples**: The specific words or phrases pointed out and suggestions for improvement.
3. **Importance**: Mark the importance to you or points that are repeatedly pointed out.
From this record, identify your weak areas and patterns of frequent mistakes, and connect them to a systematic learning plan.
* **Practice and Re-challenge (Re-challenge videos)**

1. **Posting "Revised" videos**: Post the content improved based on feedback as a new short video. By saying at the beginning, "I revised the previous XX video based on your feedback!", you provide the viewers who gave feedback with the joy of knowing "my comment was used," which increases their motivation for the next time.
2. **"Q&A" videos**: Pick up the most frequent or interesting questions and feedback received, and create a video summarizing the responses or revised expressions.
* **Gratitude and communication for feedback**

1. **Polite replies to comments**: Always reply to comments that provided feedback with gratitude. "Thank you! I'll be careful from next time," "I see, that was very helpful!"
2. **Mentioning in videos**: Introduce viewers who gave excellent feedback in the video, saying, "Based on feedback from XX-san..." This further fosters a feedback culture.
3. **Interaction via live streaming or community tab**: Hold live streams irregularly to answer questions from viewers about sign language expressions, or create a space to discuss specific expressions with viewers.
I've also been sent popular sign language-related videos, so I'd like to share those again!
