Abstract

A computer program product for managing and rendering one or more information nodes relative to a current focus. The computer program product receives one or more principal topics from an analysis of the information nodes. The computer program product determines a topic vector from a similarity of a first information node to each of the principal topics and a map from the topic vector to a storage location of the first information node. The computer program product determines one or more current topics from a second information node that has been recently accessed by a user and a current focus vector from a similarity of the one or more current topics to the one or more principal topics. The computer program product renders the current focus vector and the first information node according to a rendering algorithm that is applied to the current focus vector and the first information node.

Claims

1. A computer system for managing and rendering one or more information nodes relative to a current focus on a display device of a computer, the computer system comprising:

one or more computer processors;

one or more non-transitory computer-readable storage media; and

program instructions stored on at least one of the one or more non-transitory computer-readable storage media, the program instructions executed by at least one of the one or more processors comprising;

program instructions to receive one or more principal topics from a content of one or more information nodes visited by a user, wherein the one or more information nodes includes at least one first information node;

program instructions to determine a topic vector from a similarity of a content of the first information node to the one or more principal topics, wherein the topic vector is determined using a Latent Dirichlet Allocation algorithm;

program instructions to create a map from the topic vector to a storage location of the first information node;

program instructions to determine one or more current topics from a content of a second information node, wherein the second information node is an information node that has been accessed recently;

program instructions to determine a current focus vector from a similarity of the one or more current topics to each principal topic of the one or more principal topics, wherein the current focus vector is determined using the Latent Dirichlet Allocation algorithm;

program instructions to render a representation of the current focus vector and a representation of the first information node on the display device of the computer according to a rendering algorithm, wherein the rendering algorithm;

determines a position and a size of the representation of the current focus vector and of the first information node;

includes a force-directed drawing algorithm;

includes an algorithm that renders a content of the first information node as a word cloud; and

uses the similarity of the one or more current topics to said each principal topic of the one or more principal topics to generate a position and a size of the representation of the current focus vector and of the first information node; and

program instructions to access the first information node in the storage location by selecting the representation of the first information node.
