Abstract

The invention provides cluster page ranking equipment and method based on clustering / classification and time. The cluster page ranking equipment comprises a searcher, a cluster builder, a cluster page ranking calculator, a cluster trend generator and a cluster trend ranking device, wherein the searcher is configured to search relevant documents from data sets according to given query statements and calculate document related values of the searched documents, thus obtaining related document sets of the sequencing; the cluster builder is configured to cluster or classify the related document sets, thus obtaining a cluster; the cluster page ranking calculator based on time is configured to calculate cluster page ranking values (TCP values) based on cluster calculation on the basis of the cluster, and is a combination of document link values based on time of all the documents in the cluster and is used as a combination of the page ranking values based on time, author ranking values based on time and document library ranking values based on time of all the documents in the cluster; the cluster trend generator is configured to calculate the future TCP value of the cluster according to the TCP value; and the cluster trend ranking device is configured to sequence future TCP values, thus obtaining trend.

Description

technical field [0001] The present invention relates to trend analysis and document ranking optimization, more particularly, the present invention relates to a cluster page ranking device and method based on clustering / categorization and time that can find subfields of a specific field and analyze and discover trends in these subfields . Background technique [0002] In the field of trend analysis and document ranking optimization, reference document 1 (US20050234877A1, "System and method for searching using a temporal dimension") discloses sorting query results in time, taking into account author authority and Publishing authority. Among them, the time-based ranking uses an aging function based on the time difference between the publication time of the document and the current time and a ratio that will make the document value decrease faster the longer the publication time. However, this solution only calculates the time-based page ranking value of a single document and ...
