Patent number: 11928488Abstract: A research assistant system may include a research tool and components and a user interface to discover and evidence answers to complex research questions. The research tools may include components to iteratively perform steps in a research process, including searching, analyzing, connecting, aggregating, synthesizing, and chaining together evidence from a diverse set of knowledge sources. The system may receive an input query and perform a semantic search for key concepts in a text corpus. A semantic parser may interpret the search results. The system may aggregate and synthesize information from interpreted results. The system may rank and score the aggregated results data and present data on the user interface. The user interface may include prompts to iteratively guide user input to explore evidentiary chains and connect research concepts to produce research results annotated by evidence passages.Type: GrantFiled: January 21, 2022Date of Patent: March 12, 2024Assignee: Elemental Cognition Inc.Inventors: David A. Ferrucci, Aditya A. Kalyanpur, Shirin Saleem, Jose Barrera, Gregory H. Burnham, Kailash Karthik Saravanakumar

Patent number: 11847575Abstract: A dynamic reasoning system may include a symbolic reasoning engine that iteratively calls a dynamic rule generator to answer an input query. The symbolic reasoning engine may determine a primary goal and/or secondary goals to generate proofs for the answer. The symbolic reasoning engine may call a rules component to provide rules to prove a current input goal. The rules component may use a static rule knowledge base and/or the dynamic rule generator to retrieve and rank rules relevant to the current input goal. The dynamic rule generator may generate new rules that lead to the current input goal. The dynamic rule generator may include a statistical model that generates unstructured or structured probabilistic rules based on context related to the input query. The symbolic reasoning engine may return a list of rules with confidence for explaining the answer to the input goal.Type: GrantFiled: September 1, 2020Date of Patent: December 19, 2023Assignee: Elemental Cognition Inc.Inventors: David Ferrucci, Aditya Kalyanpur, Jennifer Chu-Carroll, Thomas Breloff, Or Biran, David Buchanan

Patent number: 11797610Abstract: A natural language interfacing system may use a knowledge acquisition tool to obtain structured representations from user input text. The system may initiate interaction with a request for input and a partial statement with blank text slots labeled by field types. The system may receive input text to fill in a slot of the partial statement and perform semantic parsing on the input text to identify a trigger concept. The system may generate a list of templates defining different semantic frames for the trigger concept. A generated template may include additional generated slots and/or suggested slot-fillers to guide user input. In response to a template selection, the partial statement includes the trigger concept annotated with a semantic frame. This process is repeated by iteratively updating the list of templates until the statement is completed. The statement is mapped to a structured representation including semantic frames.Type: GrantFiled: September 15, 2020Date of Patent: October 24, 2023Assignee: Elemental Cognition Inc.Inventors: David Ferrucci, Clifton James McFate, Aditya Kalyanpur, Andrea Bradshaw, David Melville
