We describe our efforts on knowledge extraction, linkage, and cleaning to significantly improve the coverage and quality of product knowledge.
Such methods should allow anonymous extraction and linkage of data with only the data needed to make comparisons extracted; and the privacy of the patient is primarily maintained through the researcher not having access to any strong identifiers (e.g. name, date of birth etc).
Therefore, we applied Knowledge Discovery in the Textual Databases (KDT) process to answer the questions, "what kinds of defects are reported while inspecting a marine structure, and which of them are closely related?" In particular, we propose a concept extraction and linkage approach as an "add-on" module for the Self-Organizing Map (SOM), a clustering algorithm for document organization.
We used SAS statistical software for Windows, Version 9.3 (SAS Institute, Cary, NC, USA), for data extraction, computation, linkage, processing, and sampling.
KS (Karen Smith) and BS carried out data extraction and linkage.
DBM conceived and supervised the study, including the data extraction and linkage components.
Commonalities include document triage or prioritization, extraction and linkage of important biological entities, and extraction of relations and the underlying evidence for the relations.
The KPNC information systems employ a common medical record number for all inpatient, outpatient, and administrative encounters in all facilities, permitting extraction and linkage of patient data using methods that have been previously described [ 19- 22].
Prior to every focus group and interview, the facilitator gave a short presentation as to the current problems with patient recruitment to research and how a national research register was expected to work, including information about possible mechanisms for participation and data extraction and linkage mechanisms.
Although participants were concerned about the sensitivity of some data and the security of all data and were reassured by governance and legislative controls it was difficult to ascertain their views about these issues in relation to data extraction and linkage.
