论文部分内容阅读
【目的/意义】随着数字文本数量的增加,题名与关键词作为文本表示方式之一,对文本的揭示作用日益突显。【方法/过程】基于我国农产品品牌评价领域的相关文献,对文章的题名与关键词分别进行了聚类分析,并对两者的聚类结果进行了对比,发现基于题名与基于关键词的聚类结果不完全一致,但存在交集,进而将题名与关键词叠加后进行聚类,经过分析认为聚类结果得到了改善。【结果/结论】发现题名与关键词对文献内容的揭示程度不同,且均不能良好地概括农产品品牌评价领域的文献内容,二者融合后结果得到改善;同时对今后研究中论文题名与关键词的选取提出了一些建议。
[Purpose / Significance] With the increase of the number of digital texts, the title and the key words are one of the textual expressions, and the revealing function of the texts is increasingly highlighted. [Method / Process] Based on the related literature of agricultural product brand evaluation in our country, the title and the key words of the article were respectively clustered, and the clustering results of the two were compared. It was found that based on the title and poly The result of the class is not exactly the same, but there is the intersection, and then the title and key words are clustered together. After analysis, the clustering result is improved. 【Result】 The results showed that the titles and keywords revealed different degrees to the content of the literature, and neither of them could well summarize the literature contents of the field of brand evaluation of agricultural products.
