The i2b2 Webclient has five main components, and they are laid out in the following manner.


Each component has its specific function. Click on the links below to view the details for each component.


  1. Query Tool

    The Query Tool is where queries are constructed and run. Users can specify query criteria in the group panels.  Query criteria can be any terms contained in the ontologies in the Navigate/Find Terms section, as well as past queries or query results.

  2. Navigate/Find Terms

    The Navigate/Find Terms section contains the ontologies (or vocabularies) of terms for constructing queries. You can navigate through medical ontologies using the Navigate Terms panel, or search by text or code using the Find tab.

  3. Query Status

    Query Status shows information about the state of a query, such as if it is currently running, or, when it completes, the results.  Query Report provides a textual representation of the query, while Graph Results displays various graphical representations of the results.

  4. Previous Queries

    Previously-run queries and their results are stored in Previous Queries. You can re-use them by dragging them into groups in the Query Tool or save them into the Workplace. The most recently run queries are displayed at the top. You can use Find to search for a query you are interested in.

  5. Workplace

    The Workplace panel stores useful information you may want to use or refer to later. You may store previously run queries, patient sets, individual patients, and terms. You may create folders to organize your workplace. Your workplace is private by default (only you can read or modify what's in your workplace folder), but there is a SHARED folder that everyone has access to. You may use the SHARED folder to share terms and queries with other colleagues.
