Latest Patents

Rehder holds a patent for "Methods for analysis and evaluation of the semantic content of a writing based on vector length." This invention presents a methodology for analyzing and evaluating sample texts, such as essays or documents. The process involves comparing the sample text to reference materials, analyzing the subject-matter information, and evaluating the semantic coherence of the sample. The methodology presumes an underlying semantic structure in word usage and utilizes a two-dimensional data matrix for analysis. A singular value decomposition is performed on this matrix, leading to a vector representation of both the sample and reference texts. The similarity between these texts is assessed using cosine or dot product comparisons, ultimately assigning a grade based on their degree of similarity.
