BACKGROUND OF THE
INVENTION
The embodiments of the invention relate generally to the field of text summarizers.
Text summarizers are software programs used to transform a body of text into a generally shorter and more concise body of text. Such programs assist with activities such as news reporting, financial reporting, and legal analysis. Text
summarizers typically require a user to program the summarization rules into the software if the summarizer is not adequately summarizing text. This process is time consuming, error-prone, burdensome, and requires a proficient level of programming
knowledge. Further, traditional body of text summarizers do not offer the flexibility to adapt to the writing style of particular individuals.
Therefore, there is a current need for a text summarizer that may automatically learn summarization rules based on user input and implement the summarization rules without user programming.

A method includes the steps of comparing a first body of text with a
user-created summary of the first body of text, creating rules based on
the comparison of the first body of text with the user-created summary of
the first body of text, selecting one or more summary rules for
generating a computer-created summary of a second body of text, and
applying the selected summary rules to the second body of text to
generate a computer-created summary of the second body of text. The first
body of text may be a user-corrected summary of a computer-created
summary of the first body of text. The rules may be selected based on
previous use, frequency of use, context of the body of text, or
most-specific applicability. The rules may be iteratively applied to
generate a summary. A method is also provided for generating a heading
for a summary of text.

I claim:
1. A computer-implemented method comprising the steps of: eliminating, from a portion of a body of text, the most-frequently occurring words that do not relate to the specific context
of the portion of the body of text; searching a data storage having a plurality of words and at least one summary rule associated with each word stored therein, for the remaining words within the portion of the body of text; selecting, from the data
storage, one of the summary rules associated with each remaining word found in the data storage, wherein if more than one summary rule is associated with one of the remaining words, a validated summary rule is selected over a non-validated summary rule,
if more than one validated summary rule is associated with one of the remaining words, the validated summary rule that covers the most-specific context of the remaining word is selected, and if equally-specific validated summary rules are associated with
one of the remaining words, the most- . . . . More |
