Abstract
A system and method for generating labels to characterize message content are provided. At least one component, associated with a document, is extracted from a message. Words regarding the extracted component are extracted from the message as candidate labels. Those candidate labels that are discriminative of the document associated with the extracted component are identified by comparing the candidate labels for the component with other candidate labels extracted from other messages with at least one of a same and a different component. Content of the message is characterized using the discriminative candidate labels.
Claims22
A system for generating labels to characterize message content, comprising:
- a component extraction module to extract at least one component from a message, wherein the component is associated with a document;
- a term extraction module to extract from the message, words regarding the extracted component as candidate labels;
- a label determination module to identify those candidate labels that are discriminative of the document associated with the extracted component by comparing the candidate labels for the component with other candidate labels extracted from other messages with at least one of a same and a different component;
- and
- a characterization module to characterize content of the message using the discriminative candidate labels.
A system according to claim 10, further comprising:
- a characterization module to characterize content of the opinion message as one of positive or negative, comprising:
- lists of predetermined positive words and negative words;
- an application module to apply the lists to the opinion message;
- a word identification module to identify words in the opinion message as one of positive or negative;
- and
- a word classification module to classify the opinion message as one of a positive message, a negative message, and a ratio of positive and negative words.
A method for generating labels to characterize message content, comprising:
- extracting at least one component from a message, wherein the component is associated with a document;
- extracting from the message, words regarding the extracted component as candidate labels;
- identifying those candidate labels that are discriminative of the document associated with the extracted component by comparing the candidate labels for the component with other candidate labels extracted from other messages with at least one of a same and a different component;
- and
- characterizing content of the message using the discriminative candidate labels.
