Publication number: 20220398598Abstract: Embodiments described herein are generally directed to use of a chatbot to identify a customer-specified product support issue and provide appropriate troubleshooting guidance. According to an example, free text input describing an issue associated with a product line of a vendor is received from a user via a chatbot. A vector representation of the issue is created by tokenizing and vectorizing the free text input using a word association model corresponding to the product line. It is determined whether the issue matches at least one category within multiple issue categories for the product line by performing similarity scoring between the vector representation and multiple vectors created based on top words per issue category of the multiple issue categories. Responsive to an affirmative determination, an automated, interactive, conversational troubleshooting dialog is initiated with the user via the chatbot and guided based on a decision tree for the at least one category.Type: ApplicationFiled: June 10, 2021Publication date: December 15, 2022Inventors: Mainak Das, Sean Charles Lennon, Salman Mumin Ahmed, Richard Shelby Dunlap

Publication number: 20220309250Abstract: Embodiments described herein are generally directed to training of classification models and their use by a chatbot to identify a customer-specified product support issue and provide appropriate troubleshooting guidance. According to an example, text describing an issue associated with a product line of a vendor is received via the chatbot. A vector representation of the issue is created using a word association model corresponding to the product line and trained based on a set of historical support cases relating to multiple supported issue categories for the product line. It is determined whether the issue matches a category within the supported issue categories for the product line by applying a classification model to the vector representation. When the determination is affirmative, an automated, interactive, conversational troubleshooting dialog is initiated with the user via the chatbot and guided based on a decision tree for the category within the product line.Type: ApplicationFiled: March 23, 2021Publication date: September 29, 2022Inventors: Mainak Das, Sean Charles Lennon, Salman Mumin Ahmed, Richard Shelby Dunlap

Patent number: 10266804Abstract: The invention provides a method of co-culturing mammalian muscle cells and mammalian motoneurons. The method comprises preparing one or more carriers coated with a covalently bonded monolayer of trimethoxysilylpropyl diethylenetriamine (DETA); suspending isolated fetal mammalian skeletal muscle cells in serum-free medium according to medium composition 1; suspending isolated fetal mammalian spinal motoneurons in serum-free medium according to medium composition 1; plating the suspended muscle cells onto the one or more carriers at a predetermined density and allowing the muscle cells to attach; plating the suspended motoneurons at a predetermined density onto the one or more carriers and allowing the motoneurons to attach; covering the one or more carriers with a mixture of medium composition 1 and medium composition 2; and incubating the carriers covered in the media mixture.Type: GrantFiled: May 15, 2017Date of Patent: April 23, 2019Assignee: University of Central Florida Research Foundation, Inc.Inventors: James Hickman, Mainak Das
