eComma Features

  • Comments:

    When a user highlights any part of a text, a pop-up field appears in which the user can leave a comment. Comments often prompt replies from other readers.  Thus, a single comment about a highlighted word or phrase may give rise to a threaded discussion.

  • Tags:

    A tag is a keyword or label.  A user can tag a word or phrase by dragging the cursor over that part of the text and labeling that text in the pop-up field.

  • Tag Clouds:

    When a text is tagged by a group of readers, the tags are represented visually as a cloud. The font size of the tag correlates to its frequency.

  • Word Clouds:

    eComma displays all the words in a given text in a word cloud, an iconic representation of frequency. In other words, the more frequent a word in the text, the bigger the word appears in the cloud.  Readers can glean important information by quickly glancing at a text’s word cloud and discerning the keywords.

  • Comment Clouds:

    Similar to a tag cloud and a word cloud, a comment cloud displays all the words in all the comments left by a group of readers.  The result is a visual representation of the frequency of words that appear in all of the comments.  Comment clouds are an effective way to ascertain the keywords of the group’s collective commentary.

  • List of Users:

    Every eComma user must sign in before annotating a text.  The list of users can be easily traced and sorted.   By glancing at the list of users, a teacher can ascertain how many and what kinds of annotations users have made.

  • Heat Maps:

    Heat maps are visual representations of annotation activity. eComma automatically converts annotations into a colored heat map of the text that graphically represents the behavior of the users.  The more a word or phrase is annotated, the darker the word or phrase appears in the heat map.   Heat maps are handy tools for displaying what parts of the text attract the readers’ attention.

  • Download User Comments:

    eComma allows the instructor to download all user comments from a single session as XML and to import the comments to a Google docs spreadsheet. To download the comment data, simply click download button at the top of the comment view panel.

  • Classes/groups:

    Possible with Organic Group drupal module (d6, d7). Use the userplus drupal module (d6) to improve the Organic Groups admin interface.
