Output Schema

Execution Logic
Step 1: 内容抓取
def fetch_posts(subreddit, limit=50, time_range="week"):
url = f"https://www.reddit.com/r/{subreddit}/hot.json"
params = {"limit": limit, "t": time_range}
headers = {"User-Agent": "DramaScraper/2.0"}
response = requests.get(url, params=params, headers=headers)
return response.json()["data"]["children"]
Step 2: 基础过滤
def basic_filter(post, config):
data = post["data"]
return (
data["ups"] >= config["min_upvotes"] and
data["num_comments"] >= config["min_comments"] and
data["upvote_ratio"] >= 0.65
)
Step 3: 戏剧性评分 (v2.0 Algorithm)
def calculate_dramatic_score(post):
score = 5.0 # Base score
text = f"{post['title']} {post.get('selftext', '')}".lower()
# Engagement ratio (25% weight)
engagement_ratio = post["num_comments"] / max(post["score"], 100)
score += min(engagement_ratio * 5, 2.5)
# Content length (15% weight)
word_count = len(post.get("selftext", "").split())
if 300 <= word_count <= 2000:
score += 1.5
elif 100 <= word_count < 300:
score += 1.0
# Emotion keywords (30% weight)
emotion_keywords = [
"angry", "furious", "devastated", "heartbroken", "betrayed",
"cheated", "lied", "secret", "divorce", "breakup",
"婆婆", "出轨", "离婚", "分手", "背叛"
]
keyword_matches = sum(1 for kw in emotion_keywords if kw in text)
score += min(keyword_matches / 3, 1.0) * 3
# Conflict type detection (30% weight)
if any(kw in text for kw in ["wedding", "bride", "marry"]):
score += 1.5
if any(kw in text for kw in ["cheat", "affair", "fiancé", "boyfriend"]):
score += 2.0
if any(kw in text for kw in ["boss", "work", "coworker"]):
score += 1.0
if any(kw in text for kw in ["inheritance", "money", "will"]):
score += 2.0
if any(kw in text for kw in ["mil", "mother-in-law", "family"]):
score += 1.0
return round(min(score, 10.0), 1)
Step 4: 素材提取
def extract_drama_elements(post):
data = post["data"]
text = data.get("selftext", "")
# Setting detection
locations = {
"home": ["home", "house", "apartment", "room", "家"],
"wedding_venue": ["wedding", "ceremony", "reception"],
"office": ["office", "work", "company", "meeting", "公司"],
"public": ["restaurant", "cafe", "store", "park", "餐厅"]
}
detected_location = "other"
for loc, keywords in locations.items():
if any(kw in text.lower() for kw in keywords):
detected_location = loc
break
# Conflict type detection
conflict_types = []
if any(w in text.lower() for w in ["divorce", "cheat", "affair", "breakup", "wedding"]):
conflict_types.append("relationship_crisis")
if any(w in text.lower() for w in ["boss", "work", "job", "fired", "coworker"]):
conflict_types.append("workplace_drama")
if any(w in text.lower() for w in ["mom", "dad", "family", "sister", "brother", "mil"]):
conflict_types.append("family_conflict")
if any(w in text.lower() for w in ["inheritance", "money", "will", "estate"]):
conflict_types.append("inheritance")
return {
"setting": {
"location": detected_location,
"time": "inferred_from_context",
"mood": "dramatic"
},
"characters": [],
"conflict": {
"type": conflict_types[0] if conflict_types else "interpersonal",
"trigger": "extracted_from_text",
"escalation": "extracted_from_text",
"climax": "extracted_from_text"
},
"dialogue_highlights": [],
"turning_point": "identified_from_narrative",
"emotional_arc": "analyzed_from_text"
}
Step 5: JSON 生成
def generate_output(post, dramatic_score):
data = post["data"]
return {
"source": {
"platform": "reddit",
"subreddit": data["subreddit"],
"post_id": data["id"],
"url": f"https://reddit.com{data['permalink']}",
"scraped_at": datetime.now().isoformat()
},
"engagement": {
"upvotes": data["ups"],
"comments": data["num_comments"],
"upvote_ratio": data["upvote_ratio"],
"dramatic_score": dramatic_score
},
"content": {
"title": data["title"],
"body": data.get("selftext", "")[:2000],
"drama_tags": detect_drama_tags(data),
"conflict_type": detect_conflict_type(data)
},
"drama_elements": extract_drama_elements(post),
"script_potential": {
"hook_strength": min(dramatic_score, 10),
"viral_elements": detect_viral_elements(data),
"estimated_duration": estimate_duration(data),
"genre_fit": detect_genre(data)
}
}
