Abstract
Abstract The electronic document reading and skimming system presents a document using a variable emphasis attribute. The emphasis varies based on a degree with which each term in the document represents the overall content of the document or the user's interest with respect to that document. The system and method of this invention calculates a score for each term that reflects the degree to which each term represents the overall content of the document, maps the scores to a variable emphasis attribute of a presentation system and then presents the document in accordance with the mapped scores.

Claims Analysis
Total Claims: 31
Claim 1
Independent Claim
100 words
A method for facilitating skimming by a user of a document presented on a presentation device using at least one variable emphasis attribute having at least three values, the document having a plurality of terms, the method comprising: determining a term-score for each of the plurality of terms; mapping the term-score for each of the plurality of terms onto one of the at least three values of the at least one variable emphasis attribute; and presenting to the user each of the plurality of terms of the document using the mapped values of the at least one variable emphasis attribute.
Claim 2
Independent Claim
100 words
A method for facilitating skimming by a user of a document presented on a presentation device using at least one variable emphasis attribute having at least three values, the document having a plurality of terms, the method comprising: determining a term-score for each of the plurality of terms; mapping the term-score for each of the plurality of terms onto one of the at least three values of the at least one variable emphasis attribute; and presenting to the user each of the plurality of terms of the document using the mapped values of the at least one variable emphasis attribute.
Claim 3
Dependent Claim
26 words
The method of claim 1, wherein the term-score represents the degree to which each of the plurality of terms represents the overall content of the document.
Claim 4
Dependent Claim
37 words
The method of claim 1, wherein the term-score is a product of a frequency of the term in the document and an inverse document frequency of the term in a set of documents including the presented document.
Claim 5
Dependent Claim
12 words
The method of claim 1, wherein the term-score is a term frequency.
Claim 6
Dependent Claim
13 words
The method of claim 1, wherein the term-score is a relative document frequency.
Claim 7
Dependent Claim
32 words
The method of claim 1, wherein the at least one variable emphasis attribute is at least one of color, font, font boldness, font width, length of presentation, volume, speed, pitch and frequency.
Claim 8
Dependent Claim
43 words
The method of claim 1, further comprising: receiving a command to remap the term-score from a user; remapping the term-scores to a different range of the at least one variable emphasis attribute in response to receiving the remap command; and re-presenting the document.
Claim 9
Dependent Claim
20 words
The method of claim 1, further comprising converting the plurality of terms into canonical form prior to determining the term-score.
Claim 10
Dependent Claim
22 words
The method of claim 1, further comprising assigning a predetermined value of the at least one variable emphasis attribute to stop words.
Claim 11
Dependent Claim
25 words
The method of claim 1, further comprising the step of presenting the document in a constant value of the at least one variable emphasis attribute.
Claim 12
Dependent Claim
10 words
The method of claim 1, wherein the term-score is biased.
Claim 13
Dependent Claim
15 words
The method of claim 11, wherein the term-score is biased based on identified document segments.
Claim 14
Independent Claim
94 words
An apparatus for facilitating skimming of a document by a user, the document having a plurality of terms, the apparatus comprising: a processing system that determines a term-score for each of the plurality of terms and that maps the term-score of each of the plurality of terms onto one of at least three values of at least one variable emphasis attribute usable to present the document; and a presentation system that presents each of the plurality of terms of the document using the corresponding mapped values of the at least one variable emphasis attribute.
Claim 15
Independent Claim
94 words
An apparatus for facilitating skimming of a document by a user, the document having a plurality of terms, the apparatus comprising: a processing system that determines a term-score for each of the plurality of terms and that maps the term-score of each of the plurality of terms onto one of at least three values of at least one variable emphasis attribute usable to present the document; and a presentation system that presents each of the plurality of terms of the document using the corresponding mapped values of the at least one variable emphasis attribute.
Claim 16
Dependent Claim
26 words
The apparatus of claim 13, wherein the term-score represents the degree to which each of the plurality of terms represents the overall content of the document.
Claim 17
Dependent Claim
37 words
The apparatus of claim 13, wherein the term-score is a product of a frequency of the term in the document and an inverse document frequency of the term in a set of documents including the displayed documents.
Claim 18
Dependent Claim
12 words
The apparatus of claim 13, wherein the term-score is the term frequency.
Claim 19
Dependent Claim
13 words
The apparatus of claim 13, wherein the term-score is a relative document frequency.
Claim 20
Dependent Claim
31 words
The apparatus of claim 13, wherein the at least one variable emphasis attribute is at least one of a color, font, boldness, width, length of presentation, volume, speed, pitch and frequency.
Claim 21
Dependent Claim
11 words
The apparatus of claim 13, further comprising a variable emphasis adjuster.
Claim 22
Dependent Claim

Claim 24
Dependent Claim
32 words
The apparatus of claim 13, wherein the processing system further comprises a stop word assignment system that assigns a minimum value of the at least one variable emphasis attribute to stop words.
Claim 25
Dependent Claim
10 words
The apparatus of claim 13, further comprising a mode switch.
Claim 26
Dependent Claim
29 words
