  2. 戏剧性内容识别与评分 (0-10 scale)
  3. 短剧素材结构化提取
  4. 标准化 JSON 输出

Input Schema

{
  "type": "object",
  "required": ["subreddit"],
  "properties": {
    "subreddit": {
      "type": "string",
      "enum": ["AmITheAsshole", "relationship_advice", "funny", "jokes", "StandUpComedy"],
      "description": "目标子版块"
    },
    "filter": {
      "type": "object",
      "properties": {
        "min_upvotes": { "type": "integer", "default": 1000 },
        "min_comments": { "type": "integer", "default": 50 },
        "time_range": { "type": "string", "enum": ["day", "week", "month"], "default": "week" }

Output Schema

{
  "type": "object",
  "properties": {
    "results": {
      "type": "array",
      "items": { "$ref": "#/definitions/DramaMaterial" }
    },
    "metadata": {
      "type": "object",
      "properties": {
        "scraped_count": { "type": "integer" },
        "filtered_count": { "type": "integer" },

        "execution_time_ms": { "type": "integer" }
      }
    }
  }
}

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)
        }
    }
