News Aggregator
Collects, deduplicates, categorizes, and summarizes news articles from multiple sources on any topic or keyword — delivering curated briefings, headline digests, topic-tagged story clusters, and trend signals across any domain or time window.
When to Use
- User asks for news on a specific topic, company, person, or keyword
- A daily or weekly news briefing needs to be compiled
- User wants to know "what's happening" in an industry or domain
- A topic needs to be monitored for breaking news and emerging stories
- Multiple news sources need to be aggregated into a single curated feed
- User wants to understand the narrative around a story by seeing multiple source perspectives
- Background research on a current event requires recent news coverage
Process
Define the query and parameters:
- Topic/keywords: extract main subject, entity names, and related terms from the user's request
- Time range: breaking news (last 24 hours), recent (last 7 days), or custom window
- Source types: news wire, mainstream press, trade/industry press, local news, blogs — note which the user wants
- Geography: global coverage, country-specific, or local
- Language: default to English; specify if other languages are needed
- Exclusions: types of sources or topics to suppress (e.g., "no opinion pieces", "US coverage only")
Fetch articles from multiple sources:
- Query news APIs (NewsAPI, GDELT, Google News RSS, Bing News, or individual publication RSS feeds)
- Retrieve: headline, publication name, author, publication timestamp, URL, article description/lead paragraph, category tags
- Aim for ≥3 distinct sources per story to enable perspective comparison
Deduplicate and cluster:
- Identify articles covering the same underlying story (same event, announcement, or development)
- Cluster by: headline similarity (>70% token overlap), shared named entities, and publication time proximity (within 24 hours of original report)
- Within each cluster: designate the original/breaking story and treat others as follow-ups or reactions
- Remove true duplicates (same article syndicated across multiple sites)
Categorize and tag:
- Assign primary category: Business, Technology, Politics, Health, Science, Finance, Sports, Entertainment, World, etc.
- Tag secondary topics: specific companies, people, geographies, or themes mentioned
- Assign importance tier: Breaking / Major Development / Background / Analysis / Opinion
- Flag: satire or opinion pieces that could be mistaken for factual news reporting
Assess source diversity:
- Note if coverage is dominated by one source or outlet family (e.g., all Murdoch-owned)
- Flag if a story is covered by only one source (unverified / developing)
- Identify left-leaning, right-leaning, and centrist sources when covering political topics, for balanced briefings
Summarize each story cluster:
- Write a 1–3 sentence synthesis of what happened, drawing from multiple sources
- Include the most significant facts and quotes
- Note any discrepancies between sources' accounts
Format the briefing:
- Headline digest: ranked list of top stories with single-line summaries
- Full briefing: grouped by topic/category with story summaries and source links
- Data/trend note: if multiple stories signal a broader trend, surface the meta-narrative
