A guiding diagram for the selection of a CiTO citation function for a given in-text citation

<p>A decision model for the selection of a Citation Typing Ontology (CiTO, <a href="http://purl.org/spar/cito">http://purl.org/spar/cito</a>) citation function to use for the annotation of the citation intent of an examined in-text citation based on its context. The first large row of the diagram contains three macro-categories: (1) &ldquo;Reviewing &hellip;&rdquo;, (2) &ldquo;Affecting &hellip;&rdquo;, and (3) &ldquo;Referring &hellip;&rdquo;. Each macro-category has at least two subcategories, and each subcategory refers to a set of citation functions. The first row defines the suitable citation functions for it with the help of a guiding sentence to be completed according to the chosen sub-category and citation function.&nbsp;</p> <p>To annotate the in-text citation intent using the guiding scheme (see Figure),&nbsp;we use a&nbsp;priority ranked strategy that works as follows:&nbsp;</p> <ol> <li>we match each in-text citation against at least one of the three macro-categories, i.e. &ldquo;Reviewing ...&rdquo;, &ldquo;Affecting ...&rdquo; and &ldquo;Referring ...&rdquo; (first row in Figure);</li> <li>for each macro-category we have selected in (1), we choose one or more citation functions from those provided by CiTO;</li> <li>in case we select only one citation function, then we annotate the in-text citation intent with such a value; otherwise</li> <li>we calculate the priority of each citation function we have selected by summing its value in parenthesis (from 0.1 to 0.6) with the corresponding value in the y-axis (from 10 to 50) and in the x-axis (from 1 to 8) shown in Figure. The smaller the sum, the more priority the citation function has. For instance, the priority of the citation function &ldquo;confirms&rdquo; is 11.2 that is higher than the one of the citation function &ldquo;describes&rdquo;, which is 43.2. Finally, we select the citation function that has higher priority and annotate the in-text citation function with it.</li> </ol>
