IPM NEL (Derczynski IPM Named Entity Linking)

Introduced by Leon Derczynski et al. in Analysis of Named Entity Recognition and Linking for Tweets27 Oct 2014 archive 2025-07-28

This data is for the task of named entity recognition and linking/disambiguation over tweets. It comprises the addition of an entity URI layer on top of an NER-annotated tweet dataset. The task is to detect entities and then provide a correct link to them in DBpedia, thus disambiguating otherwise ambiguous entity surface forms; for example, this means linking "Paris" to the correct instance of a city named that (e.g. Paris, France vs. Paris, Texas).

The data concentrates on ten types of named entities: company, facility, geographic location, movie, musical artist, person, product, sports team, TV show, and other.

The file is tab separated, in CoNLL format, with line breaks between tweets. Data preserves the tokenisation used in the Ritter datasets. PoS labels are not present for all tweets, but where they could be found in the Ritter data, they're given. In cases where a URI could not be agreed, or was not present in DBpedia, there is a NIL. See the paper for a full description of the methodology.

Papers archive 2025-07-28

6 shown of 6 papers with a leaderboard row on this dataset's benchmarks, newest first. The archive's own "papers using this dataset" list was never published, so this is the benchmark-backed subset; the archive's count for this dataset is 32. The Syntology column is from Syntology's graph (read 2026-09-24), stated per sample; it is not part of any archive number.
