The annotation consists of assigning an appopriate value for each dimension and identifying textual clues for each dimension, when they are present. knowledge type (KT), certainty level (CL), manner, polarity and source. Such systems can assist in a number of important tasks, e.g., finding new experimental knowledge to facilitate database curation, enabling textual inference to detect entailments and contradictions, etc.Įach event has been annotated with 5 different dimensions of meta-knowledge, i.e. This will faciltate the training of more sophisticated IE systems, which allow interpretative information to be specified as part of the search criteria. The complete GENIA event copus, consisting of 1,000 abstracts annotated with 36,858 events, has been manually enriched with meta-knowledge annotation. Statements should be interpreted, according to their textual context,Įxamples include whether a statement describing a fact, a hypothesis,Īn experimental result or an analysis of results, how confident theĪuthor is regarding the validity of her analyses, etc.Įxample: Meta-knowledge enrichment of the GENIA Event Corpus Meta-knowledge annotation is the task of identifying how factual The full shared task data are freely available from the shared The brat standoff format and a sample of the corpus annotations Organization, location and miscellaneous).Ī conversion script from the CoNLL 2002 shared task format into Recognition provided two annotated corpora (Spanish andĭutch) annotated with entities of four types (person, (CoNLL) 2002 shared task on Language-Independent Named Entity The Conference on Computational Natural Language Learning ![]() Given to tasks with freely available data.Įntity mention detection Example: CoNLL 2002 Shared Task: Language-Independent Named Entity Recognition In the selection of examples included here, priority has been Converters for many of the original formats are The examples discussed in this section have been originallyĬreated in various tools other than brat and converted intoīrat format.
