This research, "Automatic Keyphrase Extraction from Document using Unsupervised Techniques," describes machine learning algorithms that assist in identifying the Keyphrase from a statement that the user inputs and in setting a reminder using the Keyphrase. The Automatic Keyphrase Extraction Algorithm (AKPE) is help to draw out a Keyphrase from a text effectively, which minimizes the potential for human mistake and saves time, in order to overcome the difficulties in traditional ways to extract key Keyphrase from a big corpus, which mainly rely on human labor.
