Embodiment 1

[0030] Static knowledge map component data input is: Descriptor data list (fields include: serial number, descriptor name, hypernym, hypernym serial number, hyponym, related word, family head word, classification number, search guide, English name of the descriptor ), the list of descriptor relationships (the fields include: the source descriptor number of the relationship, the target descriptor number of the relationship).

[0031] The static map component contains a package map to display the overall map. The display area of ​​the space container will display a part of the package map. The size of the package map can be adjusted, and the position of the display area can be changed by dragging and other operations. At the same time, this component includes a small map to display the relative position of the overall package map and the current display area, and clicking the small map area can control the position adjustment of the package map display area. For the package grap...

Embodiment 2

[0033] The data input of the single entity relationship diagram component is: node tree structure data (each node includes: subordinate node array, associated node array, hypernym node array, hyponym node array, node number, node descriptor name), node relationship An array of (each item includes: source node descriptor name, target node descriptor name, relationship type).

[0034] The single entity relationship graph component uses a cluster graph as the basic visual graph to present the entity relationship between an entity in the knowledge graph as the source entity and other entities. Each entity represents a node in the cluster graph. The source entity is at the center of the entire cluster and is connected to other associated entity nodes by lines. Different types of associations will be represented by lines of different colors. The relationship diagram also provides the function of zooming in / out of the relationship. Click on a node, and its subordinate relationship li...

Embodiment 3

[0037]The data input of the composite entity relationship diagram component is: an array of all relationship paths (each item of the array is a path from the source descriptor node to the target descriptor node, each path is also represented by an array, and each item is a path in the path A node, each node is a descriptor object, including fields: serial number, descriptor name, hypernym, hypernym serial number, hyponym, related words, family head word, classification number, search guide, English name of the descriptor ).

[0038] The combined entity relationship diagram component uses a path diagram layout unique to this tool to present all entity relationship paths that can connect source entities with target entities. The source entity and the target entity will be located at both ends of the entire layout, and the path will be located between the two nodes. Nodes on the path represent intermediate nodes that can relate source entities to target entities. The size and c...

Abstract

The invention discloses a visual query tool for knowledge maps. The tool comprises a visual component library and a visual query system for the knowledge maps, wherein the visual component library provides an API (Application Programming Interface) to the outside; the visual query system uses components in the visual component library through calling the API; the visual component library comprisesstatic map components, single entity relationship diagram components and combined entity relationship diagram components; the visual query system comprises a map overall information displaying moduleand an entity relationship querying module; the overall information displaying module calls the static map components; and the entity relationship querying module calls the single entity relationshipdiagram components and the combined entity relationship diagram components. The tool disclosed by the invention has the advantages that the information contained in the knowledge map is graphically presented by using the visualization technology; and a knowledge map viewer can obtain the information contained in the knowledge map more quickly and more multidimensionally through operations such asquerying and the like in the visual system disclosed by the invention.

Description

technical field [0001] The invention relates to the technical field of knowledge map visualization display, in particular to a knowledge map visualization query tool. Background technique [0002] Knowledge graph is a knowledge base with graph structure, which belongs to the category of knowledge engineering. Different from ordinary knowledge bases, knowledge graphs integrate all disciplines, and link knowledge units of different sources, types, and structures into graphs. Based on the metadata of each discipline, it provides users with a wider and deeper knowledge system and continuously expansion. However, precisely because of the breadth and depth of the knowledge system, the knowledge map is a kind of graph with high complexity. Users cannot quickly obtain the knowledge they want to acquire by directly observing the map itself. [0003] The world is in an era of information explosion. With the rapid development of the Internet, the maturity and popularization of datab...
