A method for determining an optimized surveillance schedule of follow-up diagnostic tests and doctor visits considers the tradeoff between timely detection of relapse and the cost of the diagnostic procedures. A method for generating a surveillance schedule for monitoring a recurrence of a condition includes the steps of (a) scheduling an initial testing date to test for the recurrence of the condition; (b) establishing a threshold, wherein the threshold is the cost associated with a subsequent testing date over the cost per recurrence detected; and (c) scheduling each subsequent testing date to test for the recurrence of the condition when a cumulative risk of recurrence of the condition since the previous testing date exceeds the threshold. A system utilizing this method is also disclosed.

System for minimizing the cost and maximizing the effectiveness of monitoring for recurrence of a condition

A method for determining an optimized surveillance schedule of follow-up diagnostic tests and doctor visits considers the tradeoff between timely detection of relapse and the cost of the diagnostic procedures. Determining subsequent testing dates for detection of a disease includes the steps of: a.) choosing a surveillance schedule, wherein the surveillance schedule includes a plurality of time segments for which a corresponding test is scheduled, wherein the first surveillance schedule has associated therewith a plurality of probabilities representing the probabilities that relapse will be detected in the corresponding plurality of time segments of the surveillance schedule; b.) determining a solution for an equation and c.) delaying each subsequent testing date until the cost per detected relapse is below a probability threshold of C/T.

System for minimizing the cost of post-treatment follow-up and diagnostic tests

Disclosed is a computer-assisted method for finding duplicate or near-duplicate documents or text spans within a document collection by using high-discriminability text fragments. Distinctive features of the documents or text spans are identified. For each pair of documents or text spans with at least one distinctive feature in common, the distinctive features of each document or text span are compared to determine whether the pair is duplicates or near-duplicates. An apparatus for performing this computer-assisted method is also disclosed.

Disclosed is a computer-assisted method for classifying a text document according to emotion and affect. A score is assigned to each affect term in the document. An affect score is computed for the document from the scores for each affect term. The document is then classified in accordance with the affect score. An apparatus for performing the computer-assisted method is also disclosed.

A computer implemented method which does not require a stored dictionary for correcting spelling errors in a sequence of words comprises storing a plurality of spelling rules defined as regular expressions for matching a potentially illegal n-gram which may comprise less than all letters in the word and for replacing an illegal n-gram with a legal n-gram to return a corrected word, submitting a word from said sequence of words to the spelling rules and replacing a word in the string of words with a corrected word.

Method for rule-based correction of spelling and grammar errors

Disclosed is a computer-assisted method for generating a summary of or a browsing aid for a document. At an index creation time, information that is relevant to at least one dummy query and is necessary to compile at least one temporary summary for the summary or browsing aid is extracted from a document and cached for later use. The information may be compiled into the summary and saved as such. At a search time, the summary or browsing aid is generated using the information that was cached at index creation time. An apparatus for performing this computer-assisted method is also disclosed.

Method and apparatus for rapidly producing document summaries and document browsing aids

The method of recognizing the language of a single word as to spelling and grammar correction (e.g., identifying the appropriate language resources on a document, paragraph, sentence or even individual word basis), the automatic invocation of transliteration software based on the language of the words (e.g., automatic ASCII to Kanji substitution without requiring the user to explicitly switch into a Kanji mode), the automatic invocation of appropriate machine translation tools when the document's language is different from the user's native tongue(s), the use of document language identification to eliminate from database or web search results any documents which are not written in the user's native language and the automatic identification of user-appropriate languages for the user interface.
