<p>Values that cannot be coerced will be considered 'unknown' and will be returned as the MO code <code>UNKNOWN</code> with a warning.</p>
<p>Use the <code><a href="mo_property.html">mo_*</a></code> functions to get properties based on the returned code, see <em>Examples</em>.</p>
<p>The <code>as.mo()</code> function uses a novel <a href="mo_matching_score.html">matching score algorithm</a> (see <em>Matching Score for Microorganisms</em> below) to match input against the <a href="microorganisms.html">available microbial taxonomy</a> in this package. This will lead to the effect that e.g. <code>"E. coli"</code> (a microorganism highly prevalent in humans) will return the microbial ID of <em>Escherichia coli</em> and not <em>Entamoeba coli</em> (a microorganism less prevalent in humans), although the latter would alphabetically come first. The algorithm uses data from the List of Prokaryotic names with Standing in Nomenclature (LPSN) and the Global Biodiversity Information Facility (GBIF) (see <a href="microorganisms.html">microorganisms</a>).</p><div class="section">
<h3 id="coping-with-uncertain-results">Coping with Uncertain Results<a class="anchor" aria-label="anchor" href="#coping-with-uncertain-results"></a></h3>
<p>Results of non-exact taxonomic input are based on their <a href="mo_matching_score.html">matching score</a>. The lowest allowed score can be set with the <code>minimum_matching_score</code> argument. At default this will be determined based on the character length of the input, and the <a href="microorganisms.html">taxonomic kingdom</a> and <a href="mo_matching_score.html">human pathogenicity</a> of the taxonomic outcome. If values are matched with uncertainty, a message will be shown to suggest the user to evaluate the results with <code>mo_uncertainties()</code>, which returns a <a href="https://rdrr.io/r/base/data.frame.html" class="external-link">data.frame</a> with all specifications.</p>
<p>To increase the quality of matching, the <code>remove_from_input</code> argument can be used to clean the input (i.e., <code>x</code>). This must be a <a href="https://rdrr.io/r/base/regex.html" class="external-link">regular expression</a> that matches parts of the input that should be removed before the input is matched against the <a href="microorganisms.html">available microbial taxonomy</a>. It will be matched Perl-compatible and case-insensitive. The default value of <code>remove_from_input</code> is the outcome of the helper function <code>mo_cleaning_regex()</code>.</p>
<p>There are three helper functions that can be run after using the <code>as.mo()</code> function:</p><ul><li><p>Use <code>mo_uncertainties()</code> to get a <a href="https://rdrr.io/r/base/data.frame.html" class="external-link">data.frame</a> that prints in a pretty format with all taxonomic names that were guessed. The output contains the matching score for all matches (see <em>Matching Score for Microorganisms</em> below).</p></li>
<li><p>Use <code>mo_failures()</code> to get a <a href="https://rdrr.io/r/base/character.html" class="external-link">character</a> <a href="https://rdrr.io/r/base/vector.html" class="external-link">vector</a> with all values that could not be coerced to a valid value.</p></li>
<li><p>Use <code>mo_renamed()</code> to get a <a href="https://rdrr.io/r/base/data.frame.html" class="external-link">data.frame</a> with all values that could be coerced based on old, previously accepted taxonomic names.</p></li>

<h3 id="microbial-prevalence-of-pathogens-in-humans">Microbial Prevalence of Pathogens in Humans<a class="anchor" aria-label="anchor" href="#microbial-prevalence-of-pathogens-in-humans"></a></h3>
<p>The coercion rules consider the prevalence of microorganisms in humans, which is available as the <code>prevalence</code> column in the <a href="microorganisms.html">microorganisms</a> data set. The grouping into human pathogenic prevalence is explained in the section <em>Matching Score for Microorganisms</em> below.</p>

<h2 id="matching-score-for-microorganisms">Matching Score for Microorganisms<a class="anchor" aria-label="anchor" href="#matching-score-for-microorganisms"></a></h2>
<p>With ambiguous user input in <code>as.mo()</code> and all the <code><a href="mo_property.html">mo_*</a></code> functions, the returned results are chosen based on their matching score using <code><a href="mo_matching_score.html">mo_matching_score()</a></code>. This matching score \(m\), is calculated as:</p>
<p><img src="figures/mo_matching_score.png" width="300" alt="mo matching score"></p>
<p>where:</p><ul><li><p>\(x\) is the user input;</p></li>
<li><p>\(n\) is a taxonomic name (genus, species, and subspecies);</p></li>
<li><p>\(l_n\) is the length of \(n\);</p></li>
<li><p>\(lev\) is the <a href="https://en.wikipedia.org/wiki/Levenshtein_distance" class="external-link">Levenshtein distance function</a> (counting any insertion as 1, and any deletion or substitution as 2) that is needed to change \(x\) into \(n\);</p></li>
<li><p>\(p_{n}\) is the human pathogenic prevalence group of \(n\), as described below;</p></li>
<li><p>\(k_n\) is the taxonomic kingdom of \(n\), set as Bacteria = 1, Fungi = 2, Protozoa = 3, Archaea = 4, others = 5.</p></li>
</ul><p>The grouping into human pathogenic prevalence \(p\) is based on recent work from Bartlett <em>et al.</em> (2022, <a href="https://doi.org/10.1099/mic.0.001269" class="external-link">doi:10.1099/mic.0.001269</a>
) who extensively studied medical-scientific literature to categorise all bacterial species into these groups:</p><ul><li><p><strong>Established</strong>, if a taxonomic species has infected at least three persons in three or more references. These records have <code>prevalence = 1.0</code> in the <a href="microorganisms.html">microorganisms</a> data set;</p></li>
<li><p><strong>Putative</strong>, if a taxonomic species has fewer than three known cases. These records have <code>prevalence = 1.25</code> in the <a href="microorganisms.html">microorganisms</a> data set.</p></li>
</ul><p>Furthermore,</p><ul><li><p>Any genus present in the <strong>established</strong> list also has <code>prevalence = 1.0</code> in the <a href="microorganisms.html">microorganisms</a> data set;</p></li>
<li><p>Any other genus present in the <strong>putative</strong> list has <code>prevalence = 1.25</code> in the <a href="microorganisms.html">microorganisms</a> data set;</p></li>
<li><p>Any other species or subspecies of which the genus is present in the two aforementioned groups, has <code>prevalence = 1.5</code> in the <a href="microorganisms.html">microorganisms</a> data set;</p></li>
<li><p>Any <em>non-bacterial</em> genus, species or subspecies of which the genus is present in the following list, has <code>prevalence = 1.5</code> in the <a href="microorganisms.html">microorganisms</a> data set: <em>Absidia</em>, <em>Acanthamoeba</em>, <em>Acremonium</em>, <em>Aedes</em>, <em>Alternaria</em>, <em>Amoeba</em>, <em>Ancylostoma</em>, <em>Angiostrongylus</em>, <em>Anisakis</em>, <em>Anopheles</em>, <em>Apophysomyces</em>, <em>Aspergillus</em>, <em>Aureobasidium</em>, <em>Basidiobolus</em>, <em>Beauveria</em>, <em>Blastocystis</em>, <em>Blastomyces</em>, <em>Candida</em>, <em>Capillaria</em>, <em>Chaetomium</em>, <em>Chrysonilia</em>, <em>Cladophialophora</em>, <em>Cladosporium</em>, <em>Conidiobolus</em>, <em>Contracaecum</em>, <em>Cordylobia</em>, <em>Cryptococcus</em>, <em>Curvularia</em>, <em>Demodex</em>, <em>Dermatobia</em>, <em>Dientamoeba</em>, <em>Diphyllobothrium</em>, <em>Dirofilaria</em>, <em>Echinostoma</em>, <em>Entamoeba</em>, <em>Enterobius</em>, <em>Exophiala</em>, <em>Exserohilum</em>, <em>Fasciola</em>, <em>Fonsecaea</em>, <em>Fusarium</em>, <em>Giardia</em>, <em>Haloarcula</em>, <em>Halobacterium</em>, <em>Halococcus</em>, <em>Hendersonula</em>, <em>Heterophyes</em>, <em>Histomonas</em>, <em>Histoplasma</em>, <em>Hymenolepis</em>, <em>Hypomyces</em>, <em>Hysterothylacium</em>, <em>Leishmania</em>, <em>Malassezia</em>, <em>Malbranchea</em>, <em>Metagonimus</em>, <em>Meyerozyma</em>, <em>Microsporidium</em>, <em>Microsporum</em>, <em>Mortierella</em>, <em>Mucor</em>, <em>Mycocentrospora</em>, <em>Necator</em>, <em>Nectria</em>, <em>Ochroconis</em>, <em>Oesophagostomum</em>, <em>Oidiodendron</em>, <em>Opisthorchis</em>, <em>Pediculus</em>, <em>Phlebotomus</em>, <em>Phoma</em>, <em>Pichia</em>, <em>Piedraia</em>, <em>Pithomyces</em>, <em>Pityrosporum</em>, <em>Pneumocystis</em>, <em>Pseudallescheria</em>, <em>Pseudoterranova</em>, <em>Pulex</em>, <em>Rhizomucor</em>, <em>Rhizopus</em>, <em>Rhodotorula</em>, <em>Saccharomyces</em>, <em>Sarcoptes</em>, <em>Scolecobasidium</em>, <em>Scopulariopsis</em>, <em>Scytalidium</em>, <em>Spirometra</em>, <em>Sporobolomyces</em>, <em>Stachybotrys</em>, <em>Strongyloides</em>, <em>Syngamus</em>, <em>Taenia</em>, <em>Toxocara</em>, <em>Trichinella</em>, <em>Trichobilharzia</em>, <em>Trichoderma</em>, <em>Trichomonas</em>, <em>Trichophyton</em>, <em>Trichosporon</em>, <em>Trichostrongylus</em>, <em>Trichuris</em>, <em>Tritirachium</em>, <em>Trombicula</em>, <em>Trypanosoma</em>, <em>Tunga</em> or <em>Wuchereria</em>;</p></li>
<li><p>All other records have <code>prevalence = 2.0</code> in the <a href="microorganisms.html">microorganisms</a> data set.</p></li>
</ul><p>When calculating the matching score, all characters in \(x\) and \(n\) are ignored that are other than A-Z, a-z, 0-9, spaces and parentheses.</p>
<p>All matches are sorted descending on their matching score and for all user input values, the top match will be returned. This will lead to the effect that e.g., <code>"E. coli"</code> will return the microbial ID of <em>Escherichia coli</em> (\(m = 0.688\), a highly prevalent microorganism found in humans) and not <em>Entamoeba coli</em> (\(m = 0.159\), a less prevalent microorganism in humans), although the latter would alphabetically come first.</p>
