Abstract
Abstract A technique for automatically generating thematic summaries for machine readable representations of documents. The technique begins with identification of thematic terms (42,44) within the document. Afterward, each sentence of the document is scored (46-58) based upon the number of thematic terms contained within the sentence. The highest scoring sentences are selected (62) as thematic sentences.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
121 words
A processor implemented method of generating a thematic summary of a document presented in machine readable form to the processor, the document including a first multiplicity of sentences and a second multiplicity of terms, the processor implementing the method by executing instructions stored in electronic form in a memory device coupled to the processor, the processor implemented method comprising the steps of: a) selecting as thematic terms a first number of terms from the second multiplicity of terms; b) scoring each sentence of the first multiplicity of sentences based upon occurrence of thematic terms in each sentence; and c) selecting as thematic sentences a second number of sentences from the first multiplicity of sentences based upon the score of each sentence.
Claim 2
Dependent Claim
58 words
The processor implemented method of claim 1 wherein step a) comprises: i) determining a number of times each term of the second multiplicity of terms occurs in the document, and ii) selecting as thematic terms a first number of terms from the second multiplicity of terms based upon the number of times each term occurs in the document.
Claim 3
Dependent Claim
37 words
The processor implemented method of claim 1 or claim 2 further comprising the step of: d) presenting the thematic sentences to user of the processor in an order in which the thematic sentences occur in the document.
Claim 4
Dependent Claim
46 words
The processor implemented method of any one of claims 1 to 3 wherein step b) comprises incrementing the score of each sentence for each thematic term occurring in the sentence by an amount related to the frequency of occurrence of the thematic term within the document.
Claim 5
Dependent Claim
44 words
The processor implemented method of any one of claims 1 to 4 comprising, prior to step a), the steps of: d) receiving the second number from an input device coupled to the processor; and e) determining the first number based upon the second number.
Claim 6
Dependent Claim
17 words
The processor implemented method of claim 5 wherein the first number is less than the second number.
Claim 7
Dependent Claim
18 words
The processor implemented method of claim 5 or claim 6 wherein the first number is at least three.
