Abstract: Systems, methods, and apparatuses are described for determining compliance with a plurality of restrictions associated with one or more devices in an organization. First text indicating restrictions may be received, and second text indicating a current configuration of one or more devices may be received. Both sets of text may be processed by, e.g., removing a portion of the text based on a predetermined list of terms and simplifying the text using a lemmatization algorithm. A first vector and second vector may be generated based on the processed sets of text, and each vector may be weighted based on an inverse frequency of words in their respective text. Each vector may be normalized based on semantic analysis. The two vectors may be compared. Based on the comparison, third text corresponding to a portion of the second vector may be generated and transmitted to a third computing device.
