  • Information extraction across multiple expertise-specific subject areas
    Patent number: 8533211
    Abstract: Techniques are disclosed for bridging terminology differences between at least two subject areas. By way of example, a computer-implemented method includes executing the following steps on a computer. A first affinity measure is computed between a first term in a first corpus, corresponding to a first subject area, and a bridge term. A second affinity measure is computed between a second term in a second corpus, corresponding to a second subject area, and the bridge term. A third affinity measure is computed between the first term and the second term based on the first affinity measure and the second affinity measure. The bridge term is a term that appears in both the first corpus and the second corpus.
