Implicit Entity Recognition in Clinical Documents
2015
Proceedings of the Fourth Joint Conference on Lexical and Computational Semantics
Preserved Fulltext
We term those implicit entity mentions and introduce the problem of implicit entity recognition (IER) in clinical documents. ...
However, clinical documents often contain phrases that indicate the entities but do not contain their names. ...
Acknowledgement We acknowledge the medical students Logan Markins, Kara Joseph, and Robert Beaulieu of Wright State University for their assistance in creating the gold-standard corpus. ...

Here we introduce the problem of 'implicit entity recognition in clinical notes', propose a knowledge driven approach to address this problem and demonstrate the results of our initial experiments. ...
We address the problem of extracting implicit information from the unstructured clinical notes. ...
These tools recognize the named entity recognition and linking as a primary task in clinical notes. Clinical notes consist of entities indicated in both explicit and implicit manner. ...

In this paper, we present a study of textual characteristics that contribute to expression of implicit causal relations across sentence boundaries. ...
Biomedical relations are often expressed between entities occurring within the same sentence through syntactic means. ...
Whether the chemical en-tity and the disease entity may be document topics are also included as features. We simply included all entities that appear in the title of the article as document topics. ...
