DebateKG: Automatic Policy Debate Case Creation with Semantic Knowledge Graphs
Recent work within the Argument Mining community has shown the applicability
of Natural Language Processing systems for solving problems found within
competitive debate. One of the most important tasks within competitive debate
is for debaters to create high quality debate cases. We show that effective
debate cases can be constructed using constrained shortest path traversals on
Argumentative Semantic Knowledge Graphs. We study this potential in the context
of a type of American Competitive Debate, called Policy Debate, which already
has a large scale dataset targeting it called DebateSum. We significantly
improve upon DebateSum by introducing 53180 new examples, as well as further
useful metadata for every example, to the dataset. We leverage the txtai
semantic search and knowledge graph toolchain to produce and contribute 9
semantic knowledge graphs built on this dataset. We create a unique method for
evaluating which knowledge graphs are better in the context of producing policy
debate cases. A demo which automatically generates debate cases, along with all
other code and the Knowledge Graphs, are open-sourced and made available to the
public here: https://github.com/Hellisotherpeople/DebateKGComment: 8 pages, knife-edge reject from EACL 2023 and workshops, System

Skepticism about Reasoning
Less discussed than Humeās skepticism about what grounds there could be for projecting empirical hypotheses is his concern with a skeptical regress that he thought threatened to extinguish any belief when we reflect that our reasoning is not perfect. The root of the problem is the fact that a reflection about our reasoning is itself a piece of reasoning. If each reflection is negative and undermining, does that not give us a diminution of our original belief to nothing? It requires much attention to detail, we argue, to determine whether or not there is a skeptical problem in this neighborhood. For consider, if we subsequently doubt a doubt we had about our reasoning, should that not restore some confidence in our original belief? We would then have instead an alternating sequence of pieces of skeptical reasoning that cancel each othersā effects on our justification in the original proposition, at least to some degree. We will argue that the outcome of the sequence of reflections Hume is imagining depends on information about a given case that is not known a priori. We conclude this from the fact that under three precise, explanatory, and viable contemporary reconstructions of what this kind of reasoning about reasoning could be like and how it has the potential to affect our original beliefs, a belief-extinguishing regress is not automatic or necessary. The outcome of the sequence of reflections depends on further information whose character we will explain
Most Language Models can be Poets too: An AI Writing Assistant and Constrained Text Generation Studio
Despite rapid advancement in the field of Constrained Natural Language
Generation, little time has been spent on exploring the potential of language
models which have had their vocabularies lexically, semantically, and/or
phonetically constrained. We find that most language models generate compelling
text even under significant constraints. We present a simple and universally
applicable technique for modifying the output of a language model by
compositionally applying filter functions to the language models vocabulary
before a unit of text is generated. This approach is plug-and-play and requires
no modification to the model. To showcase the value of this technique, we
present an easy to use AI writing assistant called Constrained Text Generation
Studio (CTGS). CTGS allows users to generate or choose from text with any
combination of a wide variety of constraints, such as banning a particular
letter, forcing the generated words to have a certain number of syllables,
and/or forcing the words to be partial anagrams of another word. We introduce a
novel dataset of prose that omits the letter e. We show that our method results
in strictly superior performance compared to fine-tuning alone on this dataset.
We also present a Huggingface space web-app presenting this technique called
Gadsby. The code is available to the public here:

Assessing extraterrestrial regolith material simulants for in-situ resource utilization based 3D printing
This research paper investigates the suitability of ceramic multi-component materials, which are found on the Martian and Lunar surfaces, for 3D printing (aka Additive Manufacturing) of solid structures. 3D printing is a promising solution as part of the cutting edge field of future in situ space manufacturing applications. 3D printing of physical assets from simulated Martian and Lunar regolith was successfully performed during this work by utilising laser-based powder bed fusion equipment. Extensive evaluation of the raw regolith simulants was conducted via Optical and Electron Microscopy (SEM), VisibleāNear Infrared/Infrared (VisāNIR/IR) Spectroscopy and thermal characterisation via Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC). The analysis results led to the characterisation of key properties of these multi-component ceramic materials with regard to their processability via powder bed fusion 3D printing. The Lunar and Martian simulant regolith analogues demonstrated spectral absorbance values of up to 92% within the VisāNIR spectra. Thermal analysis demonstrated that these materials respond very differently to laser processing, with a high volatility (30% weight change) for the Martian analogue as opposed to its less volatile Lunar counterpart (<1% weight change). Results also showed a range of multiple thermal occurrences associated with melting, glass transition and crystallisation reactions. The morphological features of the powder particles are identified as contributing to densification limitations for powder bed fusion processing. This investigation has shown that ā provided that the simulants are good matches for the actual regoliths ā the lunar material is a viable candidate material for powder bed fusion 3D printing, whereas Martian regolith is not
Evidence: A Guide for the Uncertain
Assume that it is your evidence that determines what opinions you should have. I argue that since you should take peer disagreement seriously, evidence must have two features. (1) It must sometimes warrant being modest: uncertain what your evidence warrants, and (thus) uncertain whether youāre rational. (2) But it must always warrant being guided: disposed to treat your evidence as a guide. Surprisingly, it is very difficult to vindicate both (1) and (2). But diagnosing why this is so leads to a proposalāTrustāthat is weak enough to allow modesty but strong enough to yield many guiding features. In fact, I claim that Trust is the Goldilocks principleāfor it is necessary and sufficient to vindicate the claim that you should always prefer to use free evidence. Upshot: Trust lays the foundations for a theory of disagreement and, more generally, an epistemology that permits self-doubtāa modest epistemology

Impact of two interventions on timeliness and data quality of an electronic disease surveillance system in a resource limited setting (Peru): a prospective evaluation
<p>Abstract</p> <p>Background</p> <p>A timely detection of outbreaks through surveillance is needed in order to prevent future pandemics. However, current surveillance systems may not be prepared to accomplish this goal, especially in resource limited settings. As data quality and timeliness are attributes that improve outbreak detection capacity, we assessed the effect of two interventions on such attributes in Alerta, an electronic disease surveillance system in the Peruvian Navy.</p> <p>Methods</p> <p>40 Alerta reporting units (18 clinics and 22 ships) were included in a 12-week prospective evaluation project. After a short refresher course on the notification process, units were randomly assigned to either a phone, visit or control group. Phone group sites were called three hours before the biweekly reporting deadline if they had not sent their report. Visit group sites received supervision visits on weeks 4 & 8, but no phone calls. The control group sites were not contacted by phone or visited. Timeliness and data quality were assessed by calculating the percentage of reports sent on time and percentage of errors per total number of reports, respectively.</p> <p>Results</p> <p>Timeliness improved in the phone group from 64.6% to 84% in clinics (+19.4 [95% CI, +10.3 to +28.6]; p < 0.001) and from 46.9% to 77.3% on ships (+30.4 [95% CI, +16.9 to +43.8]; p < 0.001). Visit and control groups did not show significant changes in timeliness. Error rates decreased in the visit group from 7.1% to 2% in clinics (-5.1 [95% CI, -8.7 to -1.4]; p = 0.007), but only from 7.3% to 6.7% on ships (-0.6 [95% CI, -2.4 to +1.1]; p = 0.445). Phone and control groups did not show significant improvement in data quality.</p> <p>Conclusion</p> <p>Regular phone reminders significantly improved timeliness of reports in clinics and ships, whereas supervision visits led to improved data quality only among clinics. Further investigations are needed to establish the cost-effectiveness and optimal use of each of these strategies.</p
