Research On Spatiotemporal Data Model And Visualization Of Cultural Relics Based On Event-Ontology

As a precious material cultural heritage of mankind,cultural relics have become more and more research objects of people and institutions under the background of promoting Chinese culture.In the process of unearthing,collection,exhibition,circulation,and research of cultural relics,a large number of information resources have been generated,which contain rich temporal and spatial data.These spatio-temporal data indirectly reflect the status of cultural relics at different times and places.From the perspective of time and space,the cultural relics data is organized,and the correlations among them are explored.Visual research can not only reflect the temporal and spatial status of cultural relics,but also explore more entities.Relationship,visually and vividly display the relevant knowledge of cultural relics.Organizing,managing and researching multi-source heterogeneous cultural relics data from the perspective of time and space can better dig out the hidden information and knowledge of cultural relics data,can intuitively see the collection of events that cause cultural relics changes,and can clearly display cultural relics Related changes.This paper introduces technical methods of ontology,associated data and visualization to realize the associated organization and visual display of event-based spatiotemporal data of cultural relics.Based on the introduction of event description,the relationship between cultural relics spatiotemporal data entities and entities is standardized and described in the way of ontology modeling,and the relationship between entities and the distribution status of cultural relics are displayed in a visual manner,providing users with intuitive visualization effect.This article first combs and analyzes the research status of domestic and foreign spatio-temporal data,cultural relic information resource organization and cultural relics spatio-temporal data,and determines the theories,techniques and methods needed in this research.Secondly,clarify the temporal and spatial characteristics of cultural relics data,analyze the reasons for the temporal and spatial changes of cultural relics data,describe and summarize the events that cause temporal and spatial changes in cultural relics data,and propose a temporal-spatial data model of cultural relics based on event-ontology,and analyze the entities and attributes of temporal and spatial data of cultural relics.Carry out standardized description;and based on the release of cultural relics time-space related data,a visualization method of cultural relics data based on time-space modeling is proposed.Finally,using the spatio-temporal data of porcelain cultural relics as experimental data,according to the ontology model of cultural relics spatiotemporal data,the entities and relationships of porcelain cultural relics are standardized and organized,and D2RQ is used to publish related data,from list-based,spatial distribution,event-based and other dimensions.Visual display and analysis of time-space related data of porcelain cultural relics.The final experimental results show that the event-ontology-based spatio-temporal data modeling method of cultural relics can well realize the effective organization of cultural relics spatio-temporal data,and the cultural relic data visualization method based on spatio-temporal modeling can intuitively display the semantics between cultural relics The relationship and time-space status help users better discover new knowledge from the perspective of time and space.
