Abstract

The invention provides a subject data set multi-layer facet filtration method and system based on data quality. The method comprises the steps of constructing and saving a data quality facet classification level based on data set quality metadata in data directory; materializing a data quality facet classification layer in specific subject based on data quality facet classification level and subject data set generated by user's search data directory and visualizing the tree structure in the human-computer interaction interface; making data-quality-based subject data set filtration based on data quality facet selected by user in the above tree structure and sorting filtered results in the way selected by user; outputting filtered and sorted subject data set information in the human-computer interaction interface. The subject data set multi-layer facet filtration method and system based on data quality overcomes the weakness of existing subject data sets that filtration technology neglects data quality, facilitates users by multi-layer facet filtration to screen subject data sets fulfilling requirements for data quality, and represents a trend of development in data directory portal technology.

Description

technical field [0001] The invention belongs to the cross technical field of data set search and facet filtering, Web data directory and metadata, data quality management and other fields, and relates to a data set facet filtering technology based on data quality, especially a data quality based facet filtering technology. Method and system for multi-layer faceted filtering of subject datasets. Background technique [0002] Data is an important resource that can create huge value in today's world, and the World Wide Web (Web for short) has become a mainstream platform for data release, use, and consumption. Various data catalogs (data catalogs / catalogues) holding a large number of datasets (datasets) are centrally published on the Web, forming so-called data catalog portals (or data portals for short). The datasets in some open data (open data) catalog portals are free for data consumers (commonly referred to as "users"), such as: including the US government open data porta...
