Idea / Proposition: Relevance Score in addition to count

[c-hoffmann]

First of all: Thank you so much for providing this plugin and keeping it up-to-date!

I have edited this plugin to include a time-relative score ("relevance") in addition to the Google Scholar citation count. The idea is to allow sorting not by absolute citations, but by relevance. I thought this might help other people, though I'm unsure if it's a good idea to include this in the plugin in general. Perhaps you can consider it or some similar alternative.

I based the score on the number of citations since publication (citations / weeksSincePublication) and rounded to two decimals.

The new format in the 'Extra'-column is: GSCC: 2.22 (000020), where 2.22 is the calculated score and 000020 is the absolute citation count.

Code Changes

The changes are made in \chrome\content\gscc.js

1. buildCiteCountString

  /**
   * Create the citation string for use on the item record
   * @param {number} citeCount
   * @param {ZoteroGenericItem} item
   * @returns string
   */
  buildCiteCountString: function (citeCount, item) {
    let data;
    if (citeCount < 0) {
      data = this.__noData;
    } else {
      const formattedCiteCount = $__gscc.util.padCountWithZeros(
        citeCount.toString(),
        this.__citeCountStrLength
      );

      // Calculate relative importance score
      const publicationDate = item.getField('date');
      const weeksSincePublication = Math.ceil((new Date() - new Date(publicationDate)) / (1000 * 60 * 60 * 24 * 7));
      const citationRatio = citeCount / weeksSincePublication;
      let formattedRatio = citationRatio.toFixed(2);

      if (isNaN(formattedRatio)) {
          formattedRatio = '0.00';
      }

        data = `${formattedRatio} (${formattedCiteCount})`;
    }
    return `${this.__extraEntryPrefix}: ${data}`;
  },

2. updateItem:

  updateItem: function (item, citeCount) {
    const fieldExtra = item.getField('extra');
    const buildNewCiteCount = this.buildCiteCountString(citeCount, item);
    let revisedExtraField;

    const regex = new RegExp(`${this.__extraEntryPrefix}: \\d+\\.\\d{2} \\(\\d{7}\\)`, 'g');
    if (regex.test(fieldExtra)) {
      revisedExtraField = fieldExtra.replace(
        regex,
        buildNewCiteCount
      );
[...]

Hummmm, interesting, I dig it. Let me see about adding this in and I'll drop a few tests in to verify the new functionality. 👍
