Abstract:
1. A computer-assisted method for screening information in a set of documents, comprising: a) creating a set of concepts representing subject matter in the documents; b) creating a plurality of status labels representing relevancy of the documents to an end use for the set of documents; c) selecting a first subset of the set of documents; d) identifying occurrences of concepts from the set of concepts in each document in the first subset based on subject matter in each document; e) assigning a status label from the plurality of status labels to each document in the first subset based on relevancy of the document to the end use for the document; f) processing, using a computer, the first subset of the set of documents to learn relationships among the set of concepts and the labels and create a classification model of the relationships; g) modifying the set of concepts based on the learned relationships among the set of concepts and the status labels; h) selecting a second subset of the set of documents; i) assigning a status label from the plurality of status labels to each document in the second subset based on relevancy of the document to the end use for the document; j) processing, using the computer, the second subset to further learn relationships among the set of concepts and the labels and refine the classification model of the relationships; and k) if the classification model of the relationships is satisfactory, then screening, using the computer, the set of documents based on the classification model of the relationships, such that a subset of relevant documents is identified.
