Abstract: Systems and methods are provided for a computer-implemented method for identifying pairs of cohesive words within a text. A supervised model is trained to detect cohesive words within a text to be scored. Training the supervised model includes identifying a plurality of pairs of candidate cohesive words in a training essay and an order associated with the pairs of candidate cohesive words based on an order of words in the training essay. The pairs of candidate cohesive words are filtered to form a set of evaluation pairs. The evaluation pairs are provided via a graphical user interface based on the order associated with the pairs of candidate cohesive words. An indication of cohesion or no cohesion is received for the evaluation pairs via the graphical user interface. The supervised model is trained based on the evaluation pairs and the received indications.

Abstract: Systems and methods are provided for scoring a constructed response. The constructed response is processed according to a set of grammar rules to generate a data structure. The grammar rules specify a set of preferred responses for the item. The grammar rules utilize a plurality of variables that specify legitimate word patterns for the constructed response. It is determined whether the data structure indicates that the constructed response is included in the set of preferred responses, and if so, a maximum score is assigned to the constructed response. If the data structure indicates that the constructed response is not included in the set of preferred responses, a partial credit score for the constructed response is determined by assessing from the data structure which ones of the concepts represented by the variables are present in the constructed response. The partial credit score is assigned based on the presence of the concepts.

Abstract: The invention is an apparatus for forming an ultrasonic weld that includes a sonotrode having an ultrasonic actuator coupled to an elongate sealing end face for delivering ultrasonic energy to the webs in the sealing gap and a rotating cylindrical anvil having at least one raised portion extending longitudinally along an outer surface thereof. The raised portion has a radially outer surface, whereby the sealing gap is defined intermittently between the end face of the sonotrode and the radially outer surface of the raised portion of the anvil as the raised portion rotates past the end face of the sonotrode. The elongate sealing end face of the sonotrode has a substantially helical surface, whereby the sealing gap travels helically along the surface as the raised portion of the anvil cylinder rotates past the end face of the sonotrode.
