Current Projects

PDR/WAI System: I serve as a technical leader/systems designer and developer in the design, evaluation, and implementation of the Web-based input system named PDR/WAI for Publisher Data Review/WebMARS Assisted Indexing to help complete MEDLINE citation records from Web-based online journal issues. The system is capable of automatically providing DCMS users with data such as grant numbers, databanks, funding sources, PubMed IDs of commented articles, and check tags (MeSH terms) for verification. Furthermore, it can search and identify indexing terms which will be presented with the reasons for their selection, for user’s confirmation.
