Reddit 内容抓取 (RSS/API) 2. 戏剧性内容识别与评分 3. 短剧素材结构化提取 4. 标准化 JSON 输出 ## Input Schema ```json { "type": "object", "required": ["subreddit"], "properties": { "subreddit": { "type": "string", "enum": ["AmITheAsshole", "relationship_advice", "funny"], "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" } } }, "limit": { "type": "integer", "default": 10, "maximum": 50 } } } ``` ## Output Schema ```json { "type": "object", "properties": { "results": { "type": "array", "items": { "$ref": "#/definitions/DramaMaterial" } }, "metadata": { "type": "object", "properties": { "scraped_count": { "type": "integer" }, "filtered_count": { "type": "integer" }, "avg_dramatic_score": { "type": "number" }, "execution_time_ms": { "type": "integer" } } } } } ``` ## Execution Logic ### Step 1: 内容抓取 ```python 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/1.0"} response = requests.get(url, params=params, headers=headers) return response.json()["data"]["children"] ``` ### Step 2: 基础过滤 ```python 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 and len(data.get("selftext", "")) >= 300 ) ``` ### Step 3: 戏剧性评分 ```python def calculate_dramatic_score(post): data = post["data"] # Engagement ratio (25%) engagement_score = min(data["num_comments"] / data["ups"] * 10, 10) * 0.25 # Content length (15%) text_length = len(data.get("selftext", "")) length_score = 10 if 500 <= text_length <= 3000 else 5 length_score *= 0.15 # Emotion density (30%) emotion_words = ["angry", "furious", "heartbroken", "devastated", "shocked", "betrayed", "disappointed", "frustrated", "hate", "love", "生气", "愤怒", "伤心", "失望", "震惊"] text = data["title"] + " " + data.get("selftext", "") emotion_count = sum(1 for w in emotion_words if w.lower() in text.lower()) emotion_score = min(emotion_count / len(text.split()) * 100, 10) * 0.30 # Conflict keywords (30%) conflict_categories = { "family": ["父母", "婆婆", "老公", "离婚", "family", "parents", "mother-in-law", "divorce"], "workplace": ["老板", "同事", "裁员", "boss", "coworker", "layoff"], "relationship": ["出轨", "分手", "cheating", "breakup", "affair"], "moral": ["自私", "背叛", "selfish", "betrayal", "lying"] } conflict_hits = sum( 1 for cat in conflict_categories.values() if any(kw in text.lower() for kw in cat) ) conflict_score = min(conflict_hits * 2.5, 10) * 0.30 return round(engagement_score + length_score + emotion_score + conflict_score, 1) ``` ### Step 4: 素材提取 ```python def extract_drama_elements(post): data = post["data"] text = data.get("selftext", "") # Setting detection locations = { "home": ["home", "house", "apartment", "room", "bed", "kitchen", "家"], "office": ["office", "work", "company", "boss", "meeting", "公司"], "public": ["restaurant", "park", "street", "store", "餐厅"], "event": ["wedding", "party", "dinner", "婚礼"] } detected_location = "other" for loc, keywords in locations.items(): if any(kw in text.lower() for kw in keywords): detected_location = loc break # Character extraction characters = [] roles = { "I": "protagonist", "my wife": "supporting", "my husband": "supporting", "my boyfriend": "supporting", "my girlfriend": "supporting", "my mom": "supporting", "my dad": "supporting", "my boss": "antagonist", "MIL": "antagonist" } # Conflict type detection conflict_types = [] if any(w in text.lower() for w in ["divorce", "cheat", "affair", "breakup"]): conflict_types.append("relationship_crisis") if any(w in text.lower() for w in ["boss", "work", "job", "fired"]): conflict_types.append("workplace_drama") if any(w in text.lower() for w in ["mom", "dad", "family", "sister", "brother"]): conflict_types.append("family_conflict") return { "setting": { "location": detected_location, "time": "inferred_from_context", "mood": "dramatic" }, "characters": 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": extract_quotes(text), "turning_point": "identified_from_narrative", "emotional_arc": "analyzed_from_text" } ``` ### Step 5: JSON 生成 ```python 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) } } ``` ##
