The aim of the study was to analyze the aspects affecting broiler welfare with the use of Text Mining technique. This approach converts text into numerical data and analyzes word frequency distributions, enabling the extraction of useful information and the identification of relationships between elements. Text mining has limitations, i.e. ambiguity and context sensitivity, making it difficult to capture nuanced meanings. The search was carried out with Scopus using the term "Welfare" with the keywords "Chicken", "Broiler", "Broiler chicken", and "Chicken meat", to create a database of abstracts. Text Mining and Topic Analysis were performed on the abstracts (1228 documents) using the Software R 4.3.1., analyzing also the weight of bigram and trigram. Publications on broiler welfare are present in the bibliography since 1990's, but in the last 10 years, for the interest of public opinion, the numbers of publications significantly increased (76.5% of all documents published). USA, Brazil, and Europe-27 published 60% of the documents found. The works were published in a high number of journals, but 37% of them are published in only 4 journals (Poultry Science, Animals, Applied Animal Behavior Science and Animal Welfare). Text Mining analysis identified key terms related to the slaughter phase, housing management, and environmental conditions such as light quality and quantity. Moreover, a high correlation was found between some terms, underlying the importance of the effects of rearing, slaughter phases and litter management on broiler welfare. Most of the countries focused their research on some specific topics identified by Topic Analysis, mainly genetic selection, feeding, stocking density, slaughter, and consumer perceptions. Poultry Science published the highest number of papers (18%) and the topics more investigated were growing performance, transport and slaughter, and litter management. In conclusion, the high number of publications on chicken welfare underlines the importance of broiler welfare both in Europe and in other countries, even if it is difficult to identify common research topics among the geographic areas and the evolution over the time.
本研究的目的是利用文本挖掘技术分析影响肉鸡福利的各个方面。这种方法将文本转换为数值数据，并分析词频分布，从而能够提取有用信息并识别各要素之间的关系。文本挖掘存在局限性，即存在模糊性和上下文敏感性，难以捕捉细微的含义。使用Scopus以“福利”为检索词，并结合关键词“鸡”“肉鸡”“肉用仔鸡”和“鸡肉”进行检索，以创建一个摘要数据库。使用R 4.3.1软件对这些摘要（1228篇文献）进行文本挖掘和主题分析，同时还分析了二元组和三元组的权重。自20世纪90年代以来，文献中就有关于肉鸡福利的出版物，但在过去10年里，出于公众舆论的关注，出版物数量显著增加（占所有已发表文献的76.5%）。美国、巴西和欧盟27国发表了所检索到文献的60%。这些研究成果发表在大量期刊上，但其中37%仅发表在4种期刊上（《家禽科学》《动物》《应用动物行为科学》和《动物福利》）。文本挖掘分析确定了与屠宰阶段、饲养管理和环境条件（如光照质量和数量）相关的关键术语。此外，还发现一些术语之间存在高度相关性，这突出了饲养、屠宰阶段和垫料管理对肉鸡福利影响的重要性。大多数国家将研究重点集中在主题分析确定 的一些特定主题上，主要是遗传选择、饲养、饲养密度、屠宰和消费者认知。《家禽科学》发表的论文数量最多（18%）。研究最多的主题是生长性能、运输与屠宰以及垫料管理。总之，关于鸡福利的大量出版物凸显了肉鸡福利在欧洲和其他国家的重要性，尽管难以确定不同地理区域之间的共同研究主题以及随时间的演变情况。
