סקירה כללית

עץ מילים מתאר רצפים מקבילים מרובים של מילים. ניתן להשתמש בו כדי להראות אילו מילים מופיעות במהירות או לפני יותר ממילת יעד (למשל, "חתולים הם...") או כדי להציג היררכיה של מונחים (למשל, עץ החלטות).

עצי מילים של Google יכולים לעבד כמויות גדולות של טקסט במהירות. מערכות מודרניות צריכות להתמודד עם כמויות גדולות במיוחד של טקסט, ללא עיכוב משמעותי.

הערה: עץ המילים הוא בגרסת בטא ועשוי לבצע שינויים משמעותיים בגרסאות עתידיות של Google התרשימים.

העיבוד של עצי מילים מופעל בדפדפן באמצעות SVG, כלומר הוא יפעל בכל הדפדפנים המודרניים (למשל, ב-Chrome, Firefox, Opera ו-Internet Explorer 9 ואילך). כמו בכל התרשימים של Google, עצי מילים מציגים הסברים קצרים כשהמשתמש מרחף מעל הנתונים.

דוגמה פשוטה

נניח שבחרתם לאסוף ביטויים בנושא חתולים (למשל, "חתולים אוכלים עכברים", "חתולים טובים יותר מחתולים") ואתם רוצים להדגיש את המאפיינים החשובים ביותר בקבוצה.
