Ambiguity resolution system and method for security information retrieval

A security information system comprising:

• a computer system comprising a processor and a memory, wherein the memory comprises program code that is executable by the processor to perform steps of:
• generating, by the computer system, a unified representation model utilizing the security information mined from a group of sources, wherein the unified representation model represents terms in the security information using vectors that describe locations in space for the terms, wherein distances between the terms indicate correlations between the terms, and wherein the terms are for security concepts in the security information;
• representing, by the computer system, the security concepts utilizing a group of weighted graphs that identifies semantic relatedness between the terms utilizing the vectors in the unified representation model, wherein the group of weighted graphs enables interpreting queries with reduced ambiguity;
• interpreting, by the computer system, a seed query utilizing the group of weighted graphs;
• and
• retrieving, by the computer system, a portion of the security information utilizing the seed query interpreted utilizing the group of weighted graphs.

A computer program product for ambiguity resolution in retrieving security information, the computer program product comprising:

• a computer-readable storage media;
• first program code, stored on the computer-readable storage media, for generating a unified representation model using security information mined from a group of sources, wherein the unified representation model represents terms in the security information using vectors that describe locations in space for the terms wherein distances between the terms indicate correlations between the terms, and wherein the terms are for security concepts in the security information;
• second program code, stored on the computer-readable storage media, for representing the security concepts utilizing a group of weighted graphs that identifies semantic-relatedness between the terms utilizing the vectors in the unified representation model, wherein the group of weighted graphs enables interpreting queries with reduced ambiguity;
• third program code, stored on the computer-readable storage media, for interpreting a seed query utilizing the group of weighted graphs;
• and
• fourth program code, stored on the computer-readable storage media, for retrieving a portion of the security information utilizing the seed query interpreted utilizing the group of weighted graphs.
