=== Draw or Evaluate Annotations of Faces using "!ImageStat" Tool ===
Research is going on to improve face-detection and face-matching algorithms, for eventual incorporation into Vesuvius/PL and other projects.  To assist with algorithm training/testing and "ground truthing", images of faces are being annotated with rectangles.  A web-site tool, "!ImageStat", has been built to allow this.  Annotators are needed to use this tool on public images, e.g., of celebrities.

The specific task (broken into finite 2-3 hours chunks) may involve:
* Drawing a frontal "face" rectangle, a "profile" rectangle, and/or representative "skin" rectangles.
* Comparing such rectangles drawn by hand to rectangles marked by computer, and judging their similarity.

=== Annotate or Evaluation Extraction of Person Names, Place Names and Health Status of Missing and Found Persons ===

Research is underway to apply computer methods to extracting key features related to missing/found persons from English sentences found in free text.  The sentences may be artificial or from a collection.  Tasks may involve:
 
* Identifying certain parts of speech within a sentence, as “ground truth” tagging.
* Identifying person names, place names, and health status within a sentence, as “ground truth” tagging.
* Evaluating the accuracy of parts-of-speech tagging done by computer parsing of sentences.
 
There will likely not be task-specific software for this activity, rather the use of standard office tools like spreadsheets.  It will be helpful to be a native or very fluent English speaker with some exposure to formal grammar rules.
