Multi-faceted visualization of rich text corpora

摘要

Methods and apparatus are provided for multi-faceted visualization of rich text corpora. A data set comprising a plurality of entities, facets and relations is visualized by generating a visualization of a plurality of the facets in the data set, wherein the visualization indicates connections along the plurality of the facets in a single view using multi-faceted edges. The entities are instances of a particular concept, the facets are classes of entities and the relations are connections between pairs of the entities. A compound node comprises a representation of a primary entity, surrounded by representations of one or more secondary entities connected by one or more external relations. The internal relations can be represented as edges connecting two facet nodes from different compound nodes and a number of crossings of the edges can be reduced by adjusting a position order of facet nodes. The compound nodes can optionally be rotated based on, for example, a global spring force model to reduce an average length of one or more of the edges and/or to allow edge bundling.

1. A method for visualizing a data set, said data set comprising a plurality of entities, facets and relations, said method comprising:
generating, using at least one processing device, a visualization of a plurality of said facets in said data set, wherein said visualization indicates connections along said plurality of said facets in a single view using multi-faceted edges, wherein said entities are instances of a particular concept, said facets are classes of entities and said relations are connections between pairs of said entities, wherein said relations comprise one or more internal relations that are connections between entities within a same facet and one or more external relations that are connections between entities of different facets; rotating, using at least one processing device, one or more compound nodes to one or more of reduce an average length of one or more of said edges and allow edge bundling; and updating, using at least one processing device, said visualization based on said rotating.
