Provided are a computer program product, system, and method for pre-processing a table in a document for natural language processing (NLP). A graphical user interface (GUI) provides a representation of table items in a table in a document including a set of a main element comprising an entity whose value is to be extracted, a conditional element that refines the entity, and a value element comprising a value for the entity. Graphical controls are rendered in the GUI to enable a user to select an element from the table to be the main element, conditional element, and value element. The set of the main element, conditional element, and value element are updated with the user selected element to form a modified set. The modified set of the main element, conditional element, and the value element are provided to an NLP engine to perform natural language processing.

Pre-processing a table in a document for natural language processing

Provided are a computer program product, system, and method for pre-processing a table in a document for natural language processing. A table in a document is parsed to extract column headers, row headers, and data cells, which are processed to determine an initial set of a main element comprising an entity whose value is to be extracted, a conditional element that refines the entity, and a value element comprising a value for the entity. A user selection is received of at least one of the column headers, row headers, and data cells for at least one of the main element, conditional element, and the value element in the initial set to produce a modified set of the main element, conditional element, and value element. The modified set is provided to a natural language processing engine to perform natural language processing of the document including the table, using the modified set.

The relevancy model and the knowledge graph model are aggregated into a complimentary model including a plurality of nodes from the knowledge graph model and weights associated with edges between connected nodes, wherein the weights comprise relevance scores generated from the relevancy model, and the complimentary model is deployed for use in analyzing documents.

Extracting information from unstructured documents using natural language processing and conversion of unstructured documents into structured documents

Aspects of the present disclosure describe techniques for generating a machine learning model for extracting information from textual content. The method generally includes receiving an unstructured document and a structured document including information extracted from the unstructured document and position information associated with the extracted information. The unstructured document is rendered in a first pane, and a graphical rendering of the structured document is rendered in a second pane. The graphical rendering generally may be a structure in which content from the structured document is displayed in a hierarchical format. Each element in the structured document is linked to the rendered unstructured document based on position information included in the structured document.

A knuckle-supported wheelend assembly includes a shaft having a contoured peripheral surface portion proximate to an outboard end featuring a minimum radius and a maximum radius, and a hub mounted on the shaft's contoured surface portion via a complementary, contoured central bore. The nontapered contoured hub-shaft interface includes a slight twist or jog to reduce backlash and to permit a relative shortening of the length of axial hub-shaft engagement to as little as about 45% of the maximum radius, thereby advantageously reducing scrub radius for a given wheel-tire combination. By eliminating any required taper of the contoured interface, the hub's inboard face firmly abuts the machined face of the inner race of a knuckle-mounted, shaft-supporting bearing assembly to achieve reduced assembly runout. The hub's wheel-mounting face and integral annular friction surfaces are each machined with reference to the inboard hub face to ensure a high degree of parallelism.
