Entity linking
Technique
In natural language processing, entity linking, also referred to as named-entity disambiguation (NED), named-entity recognition and disambiguation (NERD), named-entity normalization (NEN), or concept recognition, is the task of assigning a unique identity to entities mentioned in text. For example, given the sentence "Paris is the capital of France", the main idea is to first identify "Paris" and "France" as named entities, and then to determine that "Paris" refers to the city of Paris and not to Paris Hilton or any other entity that could be referred to as "Paris" and "France" to the French country.

Entity linking finds the things the question names (projects, skills, roles, games, techniques) by their names, short names and aliases.
- Question engine (ask.chaipat.cc)
Its layers are entity linking, ordered intent rules, graph and BM25 retrieval fused by weighted reciprocal rank fusion, an answer composer that cites only what it read, a route-based confidence, a zero-result pivot for technologies the graph lacks, and follow-up questions that are validated before they are offered.
