Abstract: A method and Graphic User Interface (GUI) system of data analysis for training a discriminative machine learning model are provided. One or more sets of data are provided to a large language model (LLM) for a predefined task with or without prompts provided by a user; the results output by the LLM is compared with a set of initial human-supplied ground truth data generated by the user to produce performance metrics, the user may provide or update one or more prompts for the LLM based on the performance metrics till the performance metrics reach a threshold. The set of initial human-supplied ground truth data and the results of the LLM can be used to train a discriminative machine learning model.

Abstract: A system comprising: an input receiving an input document comprising text data and graphical data distinguishing hierarchically first and second portion of the text data; a display displaying said input document; a user interface allowing a user to add, in superposition with the displayed input document, boundary markers visually bounding said first and second text portions; and a processor arranged for, using the boundary markers added to the displayed input document, training a layout data analysis model to determine, in a further input document having further text data, if graphical data distinguishes hierarchically first and second portions of the further text data to display automatically boundary markers visually bounding said first and second portions of said further text data; the user interface allowing said user to correct the boundary markers displayed by the layout analysis model and the processor training the layout data analysis model using the corrected boundary markers.

Abstract: A graphical user interface comprising a data interface for receiving a set of text documents; a calculator for transforming each received text document into a vector of a n-dimensional manifold, n being larger than 2; transforming each n-dimensional manifold vector into a 2-D data; generating a first mapping of what 2-D data corresponds to what n-dimensional manifold vector; and generating a second mapping of what 2-D data corresponds to what received text document; a first user display arranged for displaying each 2-D data on a 2-D plane; a first user interface arranged for allowing a user to select a subset of the displayed 2-D data; wherein selecting said subset of 2-D data automatically selects the n-dimensional manifold vectors that correspond to said subset of 2-D data; and a second user display arranged for displaying a list of the text documents that correspond to said subset of 2-D data.

Abstract: One embodiment relates to a transaction system that allows one or more users to purchase or reserve goods or services using electronic computer interfaces and authorizes a receiving user to receive fulfillment of the goods or services. The membership of a shared communication context may be used to determine if the receiving user is authorized to receive fulfillment of the goods or services. Other embodiments, aspects and features are also disclosed.

Abstract: Embodiments consistent with the present invention enable multiple users, who are members of an associated communication context, to collectively purchase one or more goods or services. One embodiment relates to a method of performing a collective purchase of one or more items, which may be goods and/or services, by a set of multiple users. The one or more items to be purchased are recorded at a collective-purchasing server, and the record(s) of the one or more items may be associated with a reference to the communication context. A user may be authorized to add to, remove from, and modify the one or more items to be purchased by determining if the user is a member of the set of multiple users. Amounts are established that authorized users are to pay as part of the collective purchase. Other embodiments, aspects and features are also disclosed.

Abstract: Embodiments consistent with the present invention enable multiple users to collectively make reservations for goods or services. One embodiment relates to a method of performing a collective reservation of one or more goods or services by a set of multiple users who are members of a communication context. The communication context may be established by the set of multiple users using instances of a client software application on electronic computing devices and a collective-reservation server. Reservations may be created for multiple sets of items by the multiple users. The reservations may be modified by the multiple users, and the items under a reservation may be purchased by the multiple users. Other embodiments, aspects and features are also disclosed.
