Abstract
Abstract A system receives an information stream comprising the textual information whose semantic content is to be determined, divides the information stream into a series of elements and classifies each element into one of a plurality of predetermined classifications. The system includes a token generator and a token classifier. The token generator receives the textual information stream, parses the stream to identifies the respective elements, identifies for each element one of a plurality of element types, and generates a token identifying the element type for each element. At least some of the tokens also include a pointer pointing to the actual information associated with the element. The token classifier receives the tokens and classifies them in order. In that operation, the token classifier classifies each token in relation to the token's type, classifications for previously-classified tokens and the types of successive tokens, thereby to determine the semantic content of the information associated with the tokens. After the tokens are classified, the information associated therewith can be loaded into a database system according to their classifications, and conventional database tools used to obtain information therefrom.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
138 words
A system for receiving an information stream in the form of textual information comprising a series of information elements and generating therefrom respective classifications for said information elements from a plurality of predetermined classifications, said system comprising: A. a token generator configured to receive the information stream, parse the information stream to identify the respective information elements, identify for each information element one of a plurality of element types, and generate for each information element a token identifying the information element's element type; B. a token classifier configured to receive the tokens and generate a classification to classify each said token in relation to the element type associated with said respective token, classifications generated for previously-classified tokens and the types of previous and successive tokens, thereby to determine the semantic content of the information associated with the tokens.
Claim 2
Independent Claim
138 words
A system for receiving an information stream in the form of textual information comprising a series of information elements and generating therefrom respective classifications for said information elements from a plurality of predetermined classifications, said system comprising: A. a token generator configured to receive the information stream, parse the information stream to identify the respective information elements, identify for each information element one of a plurality of element types, and generate for each information element a token identifying the information element's element type; B. a token classifier configured to receive the tokens and generate a classification to classify each said token in relation to the element type associated with said respective token, classifications generated for previously-classified tokens and the types of previous and successive tokens, thereby to determine the semantic content of the information associated with the tokens.
Claim 3
Dependent Claim
26 words
A system as defined in claim 1 further comprising a database system, the information elements being loaded into the database system according to their respective classifications.
Claim 4
Dependent Claim
17 words
A system as defined in claim 1 in which the token classifier includes a trained classification tree.
Claim 5
Dependent Claim
23 words
A system as defined in claim 3 in which the trained classification tree is trained using a training set of properly classified tokens.
Claim 6
Dependent Claim
45 words
A system as defined in claim 4 further comprising a maintenance module for retraining the classification tree if it determines that a token is incorrectly classified, using the training set expanded by the incorrectly classified token, for which an operator has provided a proper classification.
Claim 7
Independent Claim
130 words
A method of receiving an information stream in the form of textual information comprising a series of information elements and generating therefrom respective classifications for said information elements from a plurality of predetermined classifications, said method comprising the steps of: A. receiving the information stream, parsing the information stream to identify the respective information elements, identifying for each information element one of a plurality of element types, and generating for each information element a token identifying the information element's element type; B. generating for each token a classification to classify each said token in relation to the element type associated with said respective token, classifications generated for previously-classified tokens and the types of previous and successive tokens, thereby to determine the semantic content of the information associated with the tokens.
Claim 8
Independent Claim
130 words
A method of receiving an information stream in the form of textual information comprising a series of information elements and generating therefrom respective classifications for said information elements from a plurality of predetermined classifications, said method comprising the steps of: A. receiving the information stream, parsing the information stream to identify the respective information elements, identifying for each information element one of a plurality of element types, and generating for each information element a token identifying the information element's element type; B. generating for each token a classification to classify each said token in relation to the element type associated with said respective token, classifications generated for previously-classified tokens and the types of previous and successive tokens, thereby to determine the semantic content of the information associated with the tokens.
Claim 9
Dependent Claim
24 words
