Abstract: Techniques are described for analyzing text. Embodiments tokenize a plurality of documents into a plurality of sets of terms. An average top dimension weight corresponding to the plurality of documents is calculated based on performing singular value decomposition (SVD) factorization for a plurality of dimension counts. An average inverse top dimension top term ranking for the plurality of documents is further calculated based on the SVD factorization for the plurality of dimension counts. A number of dimensions is determined based on the average top dimension weight and the average inverse top dimension top term ranking. A topic model is built for the plurality of documents based on the number of dimensions. The topic model is adapted to identify patterns of terms that correspond to semantic topics in at least the plurality of documents.

Abstract: Techniques are described for optimizing a number of dimensions for performing a singular value decomposition (SVD) factorization. Embodiments tokenize each of a plurality of documents into a respective set of terms. For each of a plurality of dimension counts, embodiments perform the SVD factorization to determine a respective plurality of dimensions, the respective plurality of dimensions corresponding to the dimension count, determine, for each of the plurality of documents, a respective set of dimension weights for each of the plurality of dimensions, calculate an average top dimension weight across the sets of dimension weights for the plurality of documents and calculate an average inverse top dimension top term ranking across the sets of dimension weights for the plurality of documents. An optimal number of dimensions is calculated, based on the average top dimension weight and the average inverse top dimension top term ranking.

Abstract: A particular method includes receiving a conflict notice from a first airfield computing agent associated with a first airfield at a first aircraft computing agent associated with a first aircraft. The conflict notice indicates that the first aircraft is associated with a first conflict of the first airfield. The method also includes identifying, based on parameters associated with the first aircraft, one or more actions associated with the first aircraft to address the first conflict.

Abstract: A cognitive decision support fleet management and maintenance decision system may comprise a first cognitive decision support system to process information regarding a plurality of platforms and generate a list of condition based response activities and a weighted ranking of the probability of success of each condition based activity. A second cognitive decision support system may be tasked by the first to, and configured to, provide a plurality of ranked courses of action. A third cognitive decision support system may be tasked by the second to, and be configured to, assess resource availability for each condition based response activity. The second cognitive decision support system may be further configured to generate from the list of condition based response activities and the resource availability assessment for each condition based response, a plurality of recommended courses of action for the platform. The courses of action may be weighted according to an order of preference in carrying out each.
