listrelated

Listrelated is a feature in information systems that generates an ordered list of items related to a given object, such as a document, page, product, or event. The goal is to help users discover content that shares meaningful connections, improving navigation, engagement, and discovery. In wikis and content management systems, a listrelated function typically analyzes metadata fields (categories, tags), internal links, titles, and the body text to determine similarity and relevance.

How it works: Basic implementations rely on keyword overlap and tag similarity; more advanced systems compute vector representations of content (TF-IDF or neural embeddings) and measure cosine similarity. Some use graph-based approaches that propagate relevance through linked structures, or collaborative signals from user interactions. The results are ranked and filtered by configurable thresholds and limits.

Implementation: Often provided as a built-in feature or extension. Configurations may include the number of results, recency weighting, diversity constraints to avoid near-duplicates, and language handling. Caching is important for performance on high-traffic sites.

Limitations: Dependence on metadata quality; risk of popularity bias; cold-start problem for new items; multilingual or domain-specific challenges.
