Embodiment Construction

[0063] During specific implementation, the technical solution provided by the present invention can be realized by those skilled in the art by using computer software technology to realize the automatic operation process. The technical solution of the present invention will be described in detail below in conjunction with the drawings and embodiments.

[0064] figure 1 It is the implementation scheme of the embodiment of the present invention, which is divided into the following processes: firstly, it is the analysis of Web tense, mainly to establish a Web temporal object model (Ttree) for different temporal sensitivities of Web information. Then, time consistency constraints and reasoning are carried out for the established Web temporal object model. Finally, through the classification and measurement of temporal inconsistencies, the temporal inconsistencies of Web information are automatically found, and the web pages are checked.

[0065] The specific implementation steps ...

Abstract

The invention discloses a web temporal object model-based outdated webpage information automatic discovering method, belongs to the field of research of data quality, and relates to the technical fields of temporal Web, network information quality estimation, semantic comprehension and extraction of temporal information, constraint and reasoning of temporal information, automatic screening of consistency of webpage information and the like. Aiming at the phenomenon of low web data quality caused by temporal inconsistency, a Web temporal object model is established on the basis of different temporal sensitivities of different web-pages, network data temporal consistency constraint relation, reasoning mechanism and an algebraic operation rule are constructed, automatic screening is performed and outdated information in the Web webpage is promoted, and information with timeliness and relevancy is provided for a network user. The method can be widely applied to the aspects such as quality ordering of similar websites and search ordering of time perception, and the Web information quality is improved to a certain extent.

Description

technical field [0001] The present invention belongs to the research category of data quality, and involves technologies such as temporal web, network information quality assessment, semantic understanding and extraction of temporal information, establishment of temporal object model and constraint relationship, reasoning mechanism and algebraic operation system of temporal information In particular, a method for automatic discovery of outdated webpage information based on the Web Temporal Object Model is proposed. Background technique [0002] Temporal Web: This project belongs to the category of temporal Web research. In recent years, tense Web has increasingly become the focus of scholars. In 2011, WWW, the most authoritative international conference on Web academics, specially set up the "Temporal Web" Workshop - TWAW. Omar Alonso et al. analyzed the types of time information in documents, the expression and formalization of time, and the labeling of time, and pointed ...
