Abstract

The invention discloses a patent introduction predicted value calculation method. The method comprises the following steps of: firstly, extracting main characteristics influencing patent introduction, wherein the main characteristics relate to write quality, novelty, technology trend, an inventor and an agent; then constructing a classifier according to historical data and patent characteristic values, calculating an initial patent introduction predicted value, constructing a patent citation network according to the similarity of patents, initializing the patent introduction predicted value of each node, and iteratively calculating the introduction predicted value of a target patent according to the nodes citing the patent as well as the introduction predicted values, out-degrees and in-degrees of patents cited by the nodes based on an idea similar to a Hits algorithm; subsequently, acquiring an interested patent set of a user based on keyword search in combination with the patent characteristics; and finally, displaying a search result in a descending order of the introduction predicted values of the patents in the patent set, and recommending the patents with high introduction possibility to the user. The patent introduction predicted value calculation method provided by the invention has the advantages of high effectiveness and timeliness.

Description

technical field [0001] The invention relates to a calculation method of a patent introduction prediction value, mainly relating to patent feature extraction, introduction evaluation and the like. Background technique [0002] In the era of knowledge economy characterized by economic globalization, the competition among enterprises has shifted from capital competition to technology competition. A broader and open financial environment makes it more important to have core technology, which relies on continuous technological innovation. As a kind of open scientific and technological documents protected by law, patent documents can reflect the innovation ability of enterprises, consolidate the technical status in the field, protect scientific research achievements from infringement, and promote the continuous emergence of advanced technology. Its importance has been paid more and more attention. According to the report of the World Intellectual Property Organization, patent doc...
