Text information clustering method and text information clustering system

摘要

One embodiment of the present application discloses a text information clustering method and system. The clustering method comprises the steps of performing word segmentation for each of a plurality of textual information, and initial clustering for a plurality of textual information for which word segmentation has been performed to form a plurality of first level topics. The first level topics each including at least two text information, and based on the number of text information below each of the first level topics according to a preset rule Determining the number of second level topics under each of the first level topics, and forming the plurality of second level topics, according to the number of second level topics under each of the first level topics Second class for at least two pieces of text information contained in each one-level topic And performing a reduction. In the present application, in the initial clustering, the hierarchical clustering method is used to reduce the total number of first level topics, thereby improving the computational efficiency and in the second clustering, the second level topics The number of is dynamically determined according to the number of text information, which accelerates the operation speed of the second level topic.
