Ontology Widgets

NCBO ontology widgets are the HTML or Javascript code that you can put on your Web site or Web form to use BioPortal functionality there. Using NCBO Widgets is just one of the ways in which you can use the NCBO Web services directly on your Web site or in your application.

Here are some examples of types of widgets:

• Term-selection field on a form: You can add a text field to your Web form that will let users enter a term from a controlled vocabulary (e.g., terms from a single ontology)
  • Example use case: Suppose you are running a tissue microarray database and users upload sample descriptions to your database using a web form. There is usually a field for the user to enter the diagnosis for the tissue sample that she is entering. Usually, this field is a text-box or a drop down menu populated with a list of controlled terms. The free text-box is prone to errors, the drop-down gets too unwieldy with large terminologies. Using the NCBO term-selection widget to have users easily select a term from an ontology or controlled vocabulary (such as the NCI Thesaurus) to fill in the field. For example, when the user starts typing "cutaneous me", the term "cutaneous melanoma" pops up.
  • What does the term-selection field get you:
    • Look-ahead so that you don't need to type the whole term
    • Controlled vocabulary provides consistency of the way different users use the term (If you want to put "Malignant melanoma", it will always be the same term from NCIT, regardless of how a user started typing it
    • When a new version of your controlled vocabulary becomes available in BioPortal, the widget will automatically use that new version.
• Ontology search widget: You can add to your Web site a search box that searches a specific BioPortal ontology. When the user selects the term of interest (with the help of the look-ahead feature), he can jump to the BioPortal page for the corresponding concept in BioPortal.
• Feed widget: you can put a widget on your site that will have a live feed of all the changes to your ontology of interest, such as uploads of a new version, comments from other users, new mappings for concepts in your ontology.
• Ontology visualization widget: You can put a widget on your Web site that visualizes your entire ontology of interest, or some part of it, as on the "Visualize" tab in BioPortal.
