ADDING PROTOTYPE INFORMATION INTO PROBABILISTIC MODELS
First Claim
1. A system for processing information, comprising:
- a module that is configured to apply a set of labels to a set of components using a probabilistic model;
a module that is configured to incorporate prototypical information in said probabilistic model by augmenting said probabilistic model with a conditional probability of the prototypical information; and
a module that is configured to determine whether said prototypical information is to be used in said probabilistic model based on a determination of at least one component in said set of components corresponding to a component in said prototypical information.

Abstract
Mechanisms are disclosed for incorporating prototype information into probabilistic models for automated information processing, mining, and knowledge discovery. Examples of these models include Hidden Markov Models (HMMs), Latent Dirichlet Allocation (LDA) models, and the like. The prototype information injects prior knowledge to such models, thereby rendering them more accurate, effective, and efficient. For instance, in the context of automated word labeling, additional knowledge is encoded into the models by providing a small set of prototypical words for each possible label. The net result is that words in a given corpus are labeled and are therefore in condition to be summarized, identified, classified, clustered, and the like.
