如何通过标题和描述找到类似的公告？

Question

我需要将一个公告与一系列其他公告进行比较，并找出哪些是相似的。 如果两个公告的标题和描述中至少有一个相同的词，则它们被认为是相似的。 它们看起来像：

[
   {title: "Test", description: "hello", id: 22},
   {title: "Test two", description: "hi", id: 49},
   {title: "Test three", description: "hello there", id: 100},
   {title: "Test four", description: "oh", id: 129},
]

Answer 1

这应该可行：

const findSimilarAnnouncements = (announcements, targetAnnouncement) => {
  const targetTitleWords = targetAnnouncement.title.split(' ');
  const targetDescriptionWords = targetAnnouncement.description.split(' ');
  
  return announcements.filter(({ title, description }) => {
    const titleWords = title.split(' ');
    const descriptionWords = description.split(' ');

    const isTitleSimilar = targetTitleWords
      .some(word => titleWords.includes(word));
    const isDescriptionSimilar = targetDescriptionWords
      .some(word => descriptionWords.includes(word));

    return isTitleSimilar && isDescriptionSimilar;
  });
};
