+- **Public:** True
+- **Tasks:** Relation Extraction, Named Entity Recognition
+
+
+HPRD50 is a dataset of randomly selected, hand-annotated abstracts of biomedical papers
+referenced by the Human Protein Reference Database (HPRD). It is parsed in XML format,
+splitting each abstract into sentences, and in each sentence there may be entities and
+interactions between those entities. In this particular dataset, entities are all
+proteins and interactions are thus protein-protein interactions.
+
+Moreover, all entities are normalized to the HPRD database. These normalized terms are
+stored in each entity's 'type' attribute in the source XML. This means the dataset can
+determine e.g. that "Janus kinase 2" and "Jak2" are referencing the same normalized
+entity.
+
+Because the dataset contains entities and relations, it is suitable for Named Entity
+Recognition and Relation Extraction.
