متن کاملJump-starting Concept Map Construction with Knowledge Extracted from Documents
Online documents provide a rich information resource for aiding the generation of concept-map-based knowledge models, but analyzing resources to select concepts and links is a time consuming task. This paper describes ongoing research on harnessing the information in unstructured textual documents, using information extraction algorithms, to generate a preliminary version of a concept map from ...
متن کاملJump-starting immune reconstitution after stem cell transplantation
Recipients of hematopoietic stem cell transplants (HSCT) are at high risk for opportunistic infection. Bacterial and certain fungal infections predominate during the immediate posttransplantation period when patients are neutropenic and have abnormal mucosal barriers. But HSCT recipients continue to be at risk for infections even after their neutropenia and mucositis have resolved. Particularly...
