Toward an Interactive Directory for Norfolk, Nebraska: 1899-1900

We describe steps toward an interactive directory for the town of Norfolk, Nebraska for the years 1899 and 1900. This directory would extend the traditional city directory by including a wider range of entities being described, much richer information about the entities mentioned and linkages to mentions of the entities in material such as digitized historical newspapers. Such a directory would be useful to readers who browse the historical newspapers by providing structured summaries of the entities mentioned. We describe the occurrence of entities in two years of the Norfolk Weekly News, focusing on several individuals to better understand the types of information which can be gleaned from historical newspapers and other historical materials. We also describe a prototype program which coordinates information about entities from the traditional city directories, the federal census, and from newspapers. We discuss the structured coding for these entities, noting that richer coding would increasingly include descriptions of events and scenarios. We propose that rich content about individuals and communities could eventually be modeled with agents and woven into historical narratives

Risk-based capital and deposit insurance reform

Risk-based capital (RBC) is an important component of deposit insurance reform. This paper provides an empirical analysis of the new 1992 RBC bank standards, applying them to data on virtually all U.S. banks from 1982 to 1989. The data reveal strong associations between several measures of future bank performance (including bankruptcy) and the RBC relative risk weights. These associations suggest that the weights constitute a significant improvement over the old capital standards, although there are several instances in which the weights for specific categories appear to be out of line with the performance results. Tests of the informational value of passing or failing the new and old capital standards show that both have independent information, but that the new RBC standards better predict future bank performance problems. The data also indicate that, in contrast to the old standards, the RBC capital burden falls much more heavily on large banks. As a result, banks representing more than one-fourth of all bank assets would have failed the new RBC standards as of 1989. The new standards are also more stringent overall. More banks would have failed the new standards than the old ones, with larger average capital deficiencies.Deposit insurance ; Bank supervision ; Bank capital

Loan commitments and bank risk exposure

Loan commitments increase a bank's risk by obligating it to issue future loans under terms that it might otherwise refuse. However, moral hazard and adverse selection problems potentially may result in these contracts being rationed or sorted. Depending on the relative risks of the borrowers who do and do not receive commitments, commitment loans could be safer or riskier on average than other loans. the empirical results indicate that commitment loans tend to have slightly better than average performance, suggesting that commitments generate little risk or that this risk is offset by the selection of safer borrowers.Bank loans ; Risk

Using Causal Threads to Explain Changes in a Dynamic System

We explore developing rich semantic models of systems. Specifically, we consider structured causal explanations about state changes in those systems. Essentially, we are developing process-based dynamic knowledge graphs. As an example, we construct a model of the causal threads for geological changes proposed by the Snowball Earth theory. Further, we describe an early prototype of a graphical interface to present the explanations. Unlike statistical approaches to summarization and explanation such as Large Language Models (LLMs), our approach of direct representation can be inspected and verified directly.Comment: 2023 ICAD

Definitions and Semantic Simulations Based on Object-Oriented Analysis and Modeling

We have proposed going beyond traditional ontologies to use rich semantics implemented in programming languages for modeling. In this paper, we discuss the application of executable semantic models to two examples, first a structured definition of a waterfall and second the cardiopulmonary system. We examine the components of these models and the way those components interact. Ultimately, such models should provide the basis for direct representation
