Highlighting User Related Advice

Research on explanation techniques for expert systems has demonstrated that (1) explanations are most effective when they address the user's needs and (2) it is necessary to augment explanations with information that is missing from the expert system‘s reasoning. It is our thesis that explanation content can also be improved by removing extraneous information from the system's reasoning and recognizing the remainder to emphasize user concerns. To test our ideas, we have developed an interactive natural language problem-solving system called ADVISOR which advises students on course selection. Previously, we have reported on our methodology for deriving user goals from the discourse, representing different points of view in the knowledge base and inferring user-oriented advice with a rule-based system that employs information from the appropriate perspective to address user goals. In this paper, we describe a model for pruning an explanation to highlight the role of the user's goal. The model is part of ADVISOR's natural language generation component. We demonstrate its efficacy with examples of different advice that ADVISOR provides for the same query in the context of different goals

Inferring User-Oriented Advice in ADVISOR

To be considered cooperative, an expert system must be easy to interact with. It must produce responses that are contextually appropriate, sensitive to the needs of users and suited to the user's level of sophistication. Expert system responses must be explained in a clear and concise fashion, often to untrained users. We have constructed a student advising system called ADVISOR, which contains a rule-based expert system, to test our ideas in natural language understanding, user modeling, use-oriented explanation, and text generation. ADVISOR assists computer science majors in course selection by providing information and offering advice during a natural language question-answering dialogue. In previous papers, we presented an overview of ADVISOR and detailed out methodologies for deriving user goals from the discourse and expressing expert system reasoning in natural language that emphasizes use goals (McKeown et al., 1985; McKeown, 1988; McKeown and Weida, 1988). In this paper we focus on how the expert with supporting justifications and additional relevant observations. Since advice is geared to the individual student, ADVISOR can provide different answers to the same questions as well as different explanations for the same answer. Indeed, its advice may change, along with the student‘s goals, as conversation progresses

Global Analysis of Nucleon Strange Form Factors at Low Q2Q^2

We perform a global analysis of all recent experimental data from elastic parity-violating electron scattering at low $Q^2$. The values of the electric and magnetic strange form factors of the nucleon are determined at $Q^2 = 0.1$ GeV/$c^2$ to be $G^s_E = -0.008 \pm 0.016$ and $G^s_M = 0.29 \pm 0.21$.Comment: 8 pages, 1 figur

Effect of Dissolved Oxygen on the Filterability of Jet Fuels for Temperatures Between 300 Degrees and 400 Degrees F

The effect of dissolved oxygen in the filter-clogging characteristics of three JP-4 and two JP-5 fuels was studied at 300 degrees to 400 degrees F in a bench- scale rig, employing filter paper as the filter medium. The residence time of the fuel at the high temperature was approximately 6 seconds. For these conditions, the clogging characteristics of the fuels increased with both increasing temperature and increasing concentration of dissolved oxygen. The amount of insoluble material formed at high temperatures necessary to produce clogging of filters was very small, of the order of 1 milligram per gallon of fuel

Chemical Probes and the Exploration of Bromodomains in Cancer Biology

The post-translational modification of histones and their interaction with transcription factors is essential to gene regulation. Furthermore, these targets would greatly benefit from probe molecules to fully elucidate their biological actions and to potentially lead to therapeutics. However, these protein-protein interactions have been considered difficult to inhibit and few high-quality chemical probes currently exist for the study of epigenetic biological systems in particular

Remote Teaching of Publication-Quality, Single-Case Graphs in Microsoft Excel

Microsoft Excel is ubiquitous, cost-effective, and can be used to create publication-quality single-case design graphs. We systematically replicated the GraphPad Prism video tutorial by Mitteer et al. (2018) to teach 24 master\u27s students to create multiple-baseline graphs using Excel 2016. Students\u27 mean accuracy on the multiple-baseline graph was 25% in pretraining, 86% with the video tutorial, and 96% with the review checklist. Next, students used the same video tutorial to create multielement and reversal graphs. Students\u27 mean accuracy on the multielement graph was 93% with video tutorial and 94% with review checklist, and accuracy on the reversal graph was 82% with video tutorial and 94% with review checklist. Students reported moderate to high satisfaction with both training components. The results support scientist-practitioners using the video tutorial and review checklists to create three common graphs using Excel 2016, Excel 2019, and Excel Office 365
