Abstract: Systems and methods for open-domain dialogue segmentation and state tracking are provided. In particular, a computing device may obtain and analyze a dialogue in near real-time, generate a structured prompt template for a state prediction model based on the dialogue, and generate a structured output using the state prediction model based on the structured prompt template. The structured output includes a turn summary and state labels for each dialogue turn.

Abstract: Various embodiments discussed herein relate to prompting a model, such as a Large Language Model (LLM), to ingest natural language clustering instructions and generate corresponding natural language clustering information, such as a cluster description and/or a cluster label without the need to generate any numeric text embeddings.

Abstract: Methods, computer systems, computer-storage media, and graphical user interfaces are provided for efficiently generating and using intent taxonomies. In embodiments, training data, including data requests for information, is obtained. Thereafter, a model prompt to be input into a large language model is generated. The model prompt includes an instruction to generate an intent taxonomy, an indication of the training data to use for generating the intent taxonomy, and a taxonomy attribute desired to be used as criteria to generate a quality intent taxonomy. An intent taxonomy that includes user intent classes is obtained as output from the large language model. The intent taxonomy is analyzed to determine whether the intent taxonomy is valid. When the intent taxonomy is determined as valid, the intent taxonomy is provided for use in identifying user intent, and when the intent taxonomy is determined as invalid, the intent taxonomy is refined.

Abstract: A process for separating bentonite and carbon carrier particles from an air-dust mixture generated from a mechanical used-sand reclamation unit and, more particularly, a process as aforesaid wherein the bentonite and carbon carrier particles are recycled to a foundry sand preparation unit.

Abstract: A method for regenerating foundry old sand which method combines impact and shearing stress of the sand grains which occurs with simultaneous dust removal. The dust removed by suction contains non-burned bentonite and carbon parts which can be re-used in the same way as the regenerated material of core sand. Environmental pollution and quantities for dumping are drastically reduced.

Abstract: A method and device for the economic and environmentally safe disposal of waste material and molten slag from a cupola furnace comprises admixing the waste material with either molten slag or granulated slag so as to form a homogeneous mixture of the waste material in the slag material and thereafter feeding the mixture to a collection container.

Abstract: The clay-bonded used casting sand is treated in a drum rotated about a horizontal axis by continuously feeding a sand additive to the drum in an amount sufficient to maintain the quantity of sand in the drum at about 26-40 percent by volume of the drum to compensate for the amount of shell material drawn off by pneumatic dust removal devices so as to maintain an optimal relationship between the volume of the drum in the quantity of sand in the drum over the entire period of treatment. The amount of sand fed to the drum may be controlled by the amount of current consumed by a motor used for rotating the drum.

Abstract: A method of flash butt welding high-carbon materials, in particular nodular cast iron wherein the arcing craters produced by intermitting contact of the contact faces have a maximum roughness depth R.sub.T such that this roughness depth lies within the narrowest thickness of the plasticized zone. As a result, when the upsetting pressure is applied, the entire molten material areas on the contact faces are pressed out of the contact faces into the welding bead thereby prohibiting the creation of hardening structures, such as, for example, ledeburite in the welding zone. The method is especially suitable for flash butt welding workpieces having wall thicknesses of over 12 mm.

Abstract: A magnesium-treated, decarburizingly-annealed cast iron material includes 4% or less carbon by weight, 2% or less silicon by weight, at least 0.010% magnesium by weight, and at least 0.001% sulphur by weight, the remainder being iron. The cast iron material is subjected to a first annealing phase in which graphitic carbon portions are formed. Thereafter, the cast iron material undergoes a second annealing phase during which certain of the graphitic carbon portions are burned out. The resultant structure includes cavities in place of certain of the graphitic carbon portions in a substantially ferritic matrix. The resultant cast iron material exhibits good welding and cutting properties with little susceptibility to hard cracking.
