A Reputation System is an online assessment mechanism that aggregates and displays user feedback to build trust and accountability within online communities.
- Context:
- It can (typically) utilize User Ratings, Feedback Comments, or Review Scores to create a numerical or qualitative assessment of users or entities.
- It can (often) serve as a foundational tool in E-commerce Platforms like Amazon, eBay, and Etsy, allowing consumers to evaluate sellers based on historical transaction data.
- ...
- It can incorporate Trust Metrics and Behavioral Analysis to prevent manipulation or abuse of the system, such as fake reviews.
- It can vary from being a Product Reputation System (e.g., Amazon product reviews) to a Personal Reputation System (e.g., Uber driver ratings).
- It can leverage Collaborative Filtering techniques to suggest reputation scores based on similar users.
- It can incentivize positive interactions by rewarding highly rated users with badges, increased visibility, or additional privileges.
- It can integrate Machine Learning Models to detect anomalous patterns in feedback and maintain system integrity.
- It can be used in Online Advice Communities such as Stack Exchange to assess the reliability of users' contributions.
- It can support Decentralized Platforms using Blockchain to maintain a tamper-resistant history of reputation scores.
- It can impact Recommender Systems by providing additional input for suggesting trusted sources or items.
- It can differ based on its Granularity, ranging from cumulative scores for entities to more detailed breakdowns for specific attributes.
- It can lead to Reputation Inflation if positive feedback is overused without critical evaluations.
- It can lead to Reputation Deflation if the feedback system is too harsh or influenced by biases.
- It can support Gamification strategies, encouraging users to build a positive reputation through competitive elements.
- It can apply to non-transactional interactions, such as ranking participants in Social Media Platforms.
- It can face challenges in ensuring Data Privacy while collecting and displaying user feedback transparently.
- It can be subject to Algorithmic Bias if the reputation scores are calculated using biased or incomplete data.
- It can be combined with Sentiment Analysis to extract nuanced feedback from textual reviews.
- It can involve User Authentication Mechanisms to prevent reputation fraud.
- It can be used for Employee Performance Assessment within organizations to measure professional reputation.

- Example(s):
- Metaculus, a prediction market that uses reputation to track and rank the accuracy of user predictions.
- eBay's Feedback System, which assigns reputation scores to buyers and sellers based on transaction history.
- Amazon's Product Review System, which aggregates user reviews to help buyers make informed purchase decisions.
- Uber's Driver Ratings, which collects rider feedback to assess driver performance and customer service.
- Stack Exchange Reputation System, which measures users' trustworthiness based on contributions and feedback from the community.
- ...
- Counter-Example(s):
- Rating Systems that do not incorporate cumulative feedback or trust metrics (e.g., standalone star ratings without user history).
- Scoring Systems used purely for gamification that do not reflect real-world interactions or trustworthiness.

- A reputation system is a program or algorithm that allow users of an online community to rate each other in order to build trust through reputation. Some common uses of these systems can be found on E-commerce websites such as eBay, Amazon.com, and Etsy as well as online advice communities such as Stack Exchange. These reputation systems represent a significant trend in "decision support for Internet mediated service provisions".[1] With the popularity of online communities for shopping, advice, and exchange of other important information, reputation systems are becoming vitally important to the online experience. The idea of reputation systems is that even if the consumer can't physically try a product or service, or see the person providing information, that they can be confident in the outcome of the exchange through trust built by recommender systems.[1]
Collaborative filtering, used most commonly in recommender systems, are related to reputation systems in that they both collect ratings from members of a community.[1] The core difference between reputation systems and collaborative filtering is the ways in which they use user feedback. In collaborative filtering, the goal is to find similarities between users in order to recommend products to customers. The role of reputation systems, in contrast, is to gather a collective opinion in order to build trust between users of an online community.
