Webpage timeliness obtaining method for temporal consistency constraint determination

Abstract

According to the webpage timeliness obtaining method for temporal consistency constraint determination, based on webpage timeliness, a temporal inconsistency intelligent recognition system of a network temporal model is provided, and comprises the construction of the network temporal model, a temporal inconsistency constraint system determination system and a temporal inconsistency intelligent recognition method based on the network temporal model. On the basis of an internal search engine, a webpage release time obtaining method based on an analytic hierarchy process model is provided, timeliness sorting is conducted on search results of the search engine through webpage release time, and timeliness retrieval is achieved. Further, the webpage timeliness is analyzed from the perspective ofwebpage content time, the positions where the time phrases possibly appear are all marked, it is guaranteed that the time phrases are extracted more sufficiently, the webpage timeliness obtaining intelligent degree is high, and the speed is high. Experiments prove that the result of the method for obtaining the webpage release time is efficient and accurate, and the retrieval result of the searchengine meets the timeliness requirement of the user.

Description

technical field [0001] The invention relates to a web page timeliness acquisition method, in particular to a webpage timeliness acquisition method for temporal consistency constraint judgment, and belongs to the technical field of webpage timeliness judgment. Background technique [0002] With the rapid development of Internet technology, information explosion seems to grow, and the pages generated by the Internet every day reach the order of tens of billions, and the era of big data has arrived. As the largest information carrier in history, the Internet's openness makes it very convenient to publish news, speeches and opinions online, which also leads to poor structure, irregularity and disorganization of information. Facing such rich but chaotic information resources, it is a huge challenge to obtain satisfactory information from them. Search engines meet people's needs for finding the information they need, but the current webpage update speed is amazing. There are mass...

Problems solved by technology

[0011] The method for obtaining the timeliness of webpages based on temporal consistency constraint judgment provided by the present invention is aimed at Internet information with poor structure, no rules, massive and disordered data, massive webpage updates on the Internet every day, and many webpages will change with time. The prior art The search engine cannot meet the needs of information search, and a high-precision webpage timeliness acquisition method is proposed, which can efficiently and accurately evaluate the timeliness of webpages, and filter out high-timeliness webpages, which not only improves the accuracy of webpage timeliness acquisition It also enhances its reliability; the present invention carefully analyzes the layout of the web page content, and marks all the positions where time phrases may appear, so as to ensure that time phrases are extracted more fully, and the timeliness of webpages is acquired with a high degree of intelligence and fast speed. A significantly innovative and advantageous method for obtaining timeliness of web pages
