Biomedical named entity recognition using two-phase model based on SVMs

Ki-Joong Lee, Young-Sook Hwang, Seonho Kim, Hae-Chang Rim
2004 Journal of Biomedical Informatics  
We try to solve these problems by separating the NE recognition task into two subtasks, where we use appropriate SVM classifiers and relevant features for each subtask.  ...  In addition, by employing a hierarchical classification method based on ontology, we effectively solve the multiclass problem concerning semantic classification.  ...  For instance, the MEDLINE database [11] contains over 12 million abstracts and many new abstracts are added monthly.  ...

2008 Bioinformatics  
Results: Here, we introduce a new measure for protein structure similarity and propose a novel method called phenotypic plasticity method (PPM) which explicitly tries to model the evolutionary distance  ...  method which models the cost of mutations, insertions and deletions occurring in protein sequences on the structure level is still missing.  ...  This set-up becomes for example important for folds which contain only one family and need to be extended by a new family ('protein structure threading').  ...
