Abstract: A system to maintain a knowledge base including a device to: (i) generate a first interface to: receive a query for transmission to a question-answer system and provide a response including one or more proposed triple in a list, (ii) after selection of a particular triple, generate a second interface to: provide at least one evidence record including a span of text in support of the particular triple, and provide one or more control element associated with each evidence record including at least one of: a first control element selectable to cite its corresponding evidence record and span of text as supporting the particular triple, or a second control element selectable to prevent its corresponding evidence record and span of text from being cited as supporting the particular triple, and (iii) generate a data structure, based on selections of the one or more control element, to update the knowledge base.

Abstract: A method for valuation in heterogeneous real property systems includes extracting, from a legacy property management system, a legacy system property data defined for a target real estate property from a legacy property management system, converting the legacy system property data from a legacy data format to a standardized format to obtain converted property data, and transmitting the converted property data to an orchestrator. The orchestrator queries a valuation tree with multiple property attributes from the converted property data to obtain a valuation model. The method further includes applying the valuation model to the converted property data to obtain multiple valuation results, generating a property value from valuation results, appending the property value to valuation results, and storing valuation results with a real estate property identifier for the target real estate property.

Abstract: Hyperlinks are automatically created and inserted into a subject document at the location of a subject concept within the subject document. The determination of when and where to insert the hyperlinks is made on the basis of associations of the subject concept with one or more object resources (to which the hyperlinks will point) according to semantic relationships between the subject concepts and the object resources as defined by a taxonomy. The hyperlinks may be displayed within a published version of the subject document in response to a cursor-control event.
