This paper describes HERD, a multilingual named entity recognizer and linker. HERD is based on the links in Wikipedia to resolve mappings between the entities and their different names, and Wikidata as a language-agnostic reference of entity identifiers. HERD extracts the mentions from text using a string matching engine and links them to entities with a combination of rules, PageRank, and feature vectors based on the Wikipedia categories. We evaluated HERD with the evaluation protocol of ERD’14 (Carmel et al., 2014) and we reached the competitive F1-score of 0.746 on the development set. HERD is designed to be multilingual and has versions in English, French, and Swedish.
