PIE is no longer publicly availble.

PIE (Protein Interaction information Extraction)1) is a configurable web service to extract protein-protein interaction (PPI) sentences from biomedical literature. Due to various reasons including hardware age, we decided to discontinue the service. If you still would like to run PIE, please contact skim at bi.snu.ac.kr.

A newer, but different version, PIE the search2), is available, however this only focuses on searching PPI informative articles from PubMed. Please, visit PIE the search for more details.
