Problems solved by technology
[0004] Due to the huge and complex knowledge base of local chronicles, its calculation volume increases exponentially with the increase of the number of knowledge sources; secondly, the fusion process is complicated and there are many constraints, and the fusion process often gives an overestimation, and its decision-making contains more subjectivity; at the same time, the reliability of search results for local chronicles is poor
The parameters of existing scanner measurement models are inaccurate and noisy
[0005] The existing data classification software has a high error rate and the classification function is not strong

The invention belongs to the technical field of local chronicle literature visualization. The invention discloses a local chronicle literature visualization method and system based on WebGIS. The local chronicle literature visualization system based on WebGIS comprises a scanning module, a main control module, a local literature data classification module, a geographic position matching module, adigital graph conversion module, a fusion module, a search optimization module, a data storage module and a display module. The fuzzy set theory is combined through the fusion module, and the fusion efficiency is high. Priori knowledge is added, and the result is more reliable. Meanwhile, targeted vocabulary supplement is carried out on the default lexicon before searching is carried out through the searching optimization module, so that the accuracy of lexical analysis is improved. According to the technical scheme, the calculation formula of the matching degree of the search algorithm is optimized, so that the search result is more accurate, the words at the middle interval are labeled, the semantic characteristics input by a user are protected to the maximum extent, and the reliabilityof the geography knowledge search result is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of local chronicle documents visualization, in particular to a method and system for local chronicle document visualization based on WebGIS. Background technique [0002] WebGIS (Web Geographic Information System) refers to the GIS working on the Web, which can realize the basic functions of GIS such as retrieval, query, cartographic output, and editing of spatial data. WebGIS: Publish and apply geospatial data through the Internet to realize the sharing and interoperability of spatial data, such as online query and business processing of GIS information. GIS has been extended through Web capabilities and has truly become a tool for the general public. Let GIS enter thousands of households. GIS geographic information system (Geographic Information System, GIS) is sometimes called "geographic information system". It is a technical system that collects, stores, manages, calculates, analyzes, displays and de...
