Fig. 1From: LPInsider: a webserver for lncRNA–protein interaction extraction from the literatureThe flowchart of LPInsider. The flowchart consists of six parts: (1) typing literature, (2) text preprocessing, (3) named entity recognition, (4) Extracting text features, (5) classification by logistic regression, (6) outcome including entity information and the judgment of positive or negative samples. For example, after users type “BC1 RNA associates with Pura”, webserver recognizes that BC1 is lncRNA and Pura is protein, and finds the interac-tion between BC1 and Pura. Users get the result returned by webserverBack to article page
