A Computer Science Technique Might Assist Determine When The Pandemic is ‘Over’

In early 2022, nearly 2 years after Covid was stated a pandemic by the World Health Organization, experts are mulling a big concern: when is a pandemic “over”?

So, what’s the response? What standards should be used to identify the “end” of Covid’s pandemic stage? These are deceivingly simple questions and also there are no easy responses.

I am a computer researcher who checks out the advancement of ontologies. In computing, ontologies are a way to formally structure understanding of a subject domain. With its entities, relationships, and constraints. So that a computer can process it in numerous applications. As well as assist human beings to be more precise.

Applying ontologies

Ontologies can uncover expertise that’s been overlooked until now: in one instance, an ontology identified 2 added practical domain names in phosphatase (a group of enzymes). As well as a unique domain name style of a part of the enzyme. Ontologies also underlie Google’s Knowledge Graph that’s behind those knowledge panels on the right-hand side of a search results page.

Using ontologies to the questions I posed at the start works. This strategy helps to clarify why it is hard to specify a cut-off point at which a pandemic can be stated “over”. The process includes collecting definitions and also characterizations from domain specialists. Like epidemiologists and infectious disease researchers. Seeking advice from the relevant studies. As well as other ontologies, and investigating the nature of what entity “X” is.

” X”, right here, would be the pandemic itself not a simple shorthand meaning. However, considering the properties of that entity. Such a precise characterization of the “X” will certainly likewise reveal when an entity is “not an X”. As an example, if X = home, a building of homes is that all should have a roof covering; if some item does not have roofing, it definitely isn’t home.

With those characteristics in hand, accurate, formal requirements can be created, helped by extra approaches and tools. From that, what or when of “X” the pandemic mores than, or it is not would realistically follow. If it doesn’t, at least it will certainly be feasible to describe why points are not that straightforward.

This sort of precision complements health and wellness specialists’ initiatives. Helping human beings to be much more exact. As well as communicate much more exactly. It compels us to make implicit assumptions explicit and makes clear where disputes may be.

Meanings and also layouts

I performed an ontological analysis of the “pandemic”. Initially, I needed to locate interpretations of a pandemic.

Informally, an epidemic is an event throughout which there are multiple instances of a transmittable condition in organisms. For a minimal duration of time, that affects a neighborhood of claimed microorganisms living in some area. A pandemic, as a minimum, expands the region where the infections occur.

Next off, I drew from an existing foundational ontology. This has generic classifications like “object”, “procedure”, and also “high quality”. I likewise utilized domain name ontologies, which contain entities certain to a subject domain, like contagious diseases. Among other resources, I consulted the Transmittable Disease Ontology. And also the Detailed Ontology for Linguistic and Cognitive Design.

Initially, I lined up “pandemic” to a fundamental ontology. Making use of a decision layout to simplify the procedure. This assisted to exercise what example as well as generic classification “pandemic” is:

(1) Is [pandemic] something that is occurring or occurring? Yes (perduring, i.e., something that unfolds in time, as opposed to being entirely present).

(2) Are you able to be existing or join [a pandemic] Yes (occasion).

(3) Is [a pandemic] atomic, i.e., has no subdivisions as well as has a definite endpoint? No (achievement).

The word “accomplishment” might seem strange right here. However, in this context, it makes clear that a pandemic is a temporal entity with a minimal lifespan. And also will evolve that is, stop being a pandemic and also advance back to the epidemic. As shown in this diagram.

Attributes

Next off, I checked out a pandemic’s characteristics explained in the literature. A detailed checklist is explained in a paper by US contagious illness experts published in 2009 during the global H1N1 flu virus outbreak. They collated 8 features of a pandemic.

I provided them and evaluated them from an ontological viewpoint:

Wide geographical extension. This is an imprecise attribute be it fuzzy in the mathematical feeling or approximated by various other ways: there isn’t a crisp limit when “vast” begins or ends.

Disease motion: there’s a transmission from area to location. And that can be traced. A yes/no particular, but it could be made categorical or with ranges of exactly how slowly or quick it relocates.

High attack prices and quickness, or: many people are impacted in a brief time span. Numerous, short, rapid all suggest inaccuracy.

Very little populace resistance: resistance is loved one. You have it to a degree to some or all of the versions of the infectious representative. As well as likewise for the population. This is a naturally unclear attribute.

Novelty: A yes/no feature, but one can add “partial”

Infectiousness: it must be transmittable (excluding non-infectious things, like weight problems), so a clear yes/no.

Contagiousness: this might be from person to person or with some other medium. This property consists of human-to-human, human-animal intermediary (e.g., fleas, rats). And also human-environment (significantly: water, as with cholera). As well as their attendant facets.

Extent: Historically, the term “pandemic” has been applied more often for severe illnesses. Or those with high casualty prices (e.g., HIV/AIDS) than for milder ones. This has some subjectivity, as well as, therefore, may be fuzzy.

Residences with inaccurate limits irritate epidemiologists. Since they may lead to different results in their forecast designs. But from my ontologist’s point of view, we’re getting somewhere with these buildings. From the computational side. Automated thinking with unclear functions is feasible.

COVID, a minimum of early in 2020, conveniently ticked all 8 boxes. A suitably automated reasoner would certainly have categorized that situation as a pandemic. But now, in early 2022? Seriousness (point 8) has greatly reduced and resistance (factor 4) has climbed. Point 5 are there worse variations of the problem ahead is the million-dollar question. The much more ontological analysis is required.

Highlighting the troubles

Ontologically speaking, then, a pandemic is an event (” success”) that unravels in time. To be categorized as a pandemic, there are a number of functions that aren’t all crisp. As well for which the inaccurate limits have not all been established. Alternatively, it indicates that classifying the event as “not a pandemic” is just as imprecise.

This isn’t a complete solution as to what a pandemic is ontologically. But it does clarify the problems of calling it “over”– and illustrates well that there will certainly be a difference regarding it.
