Reddit 内容抓取 (JSON Feed/API) 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 ```json { "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" } } }, "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/2.0"} 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 ) ``` ### Step 3: 戏剧性评分 (v2.0 Algorithm) ```python 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 ```python 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 ```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) } } ``` ##
