Abstract:
We define awareness as the cognitive interface between decision-makers and a complex system, expressed in a range of terms or features, or specific vocabulary or lexicon, to describe the attributes and surrounding environment of the system. Lexical Link Analysis (LLA) is a form of text mining in which word meanings represented in lexical terms (e.g., word pairs) can be represented as if they are in a community of a word network. In the past, we have explored how LLA systematically and automatically discovers new patterns that were previously unknown, and identifies data dependencies from large-scale defense acquisition data of multiple programs that might be indicators for program or investment performances in defense acquisition decision-making and research communities. We also started to apply LLA to improve our understanding of the quality of the data by comparing categories of information and by detecting data overlaps, inconsistency, and gaps from a single program point of view.
