The Demo contains sample reports for the domains of discharge summaries ("D/C"), radiographic reports of the chest ("CXR") and mammography reports ("Mammo"). If you select a sample report, the report will appear in the text window.

To process reports :

Select a report on the left. After the report appears in the text window, select parameters and process the report.

The user may select the following types of parameters or use the default values:

choose one of indented (default), hl7, markup, nested, xml or line.

Markup highlights certain information in the original report; clinical conditions are shown in red, medications in green, and procedures in blue.

Hl7 is used to upload data to the CIS patient database. This form contains MED Codes and also shows the corresponding MED terms.

Line consists of nested lists; it is a general form showing the structured extracted information before encoding. This form of output is useful as input to other automated applications.

Indented is useful for presenting data to the user in th most readable form; it shows a single finding on a new line; subsequent indented lines show modifiers of the finding.

XML consists of XML output.

choose one of best (default), mode1, mode2, mode3, mode4, or mode5. Mode 1 is the most accurate and mode 5 is the least accurate, but results in the highest recall. Mode "best" tries to get a parse using the most accurate mode first; if that mode is not successful, the next most accurate mode is tried, etc.
