nlp-machine-learning

Natural language processing (NLP) is a field of computer science that studies how computers and humans interact. In the 1950s, Alan Turing published an article that proposed a measure of intelligence, now called the Turing test. More modern techniques, such as deep learning, have produced results in the fields of language modeling, parsing, and natural-language tasks.

基于在线民宿 UGC 数据的意见挖掘项目,包含数据挖掘和NLP 相关的处理,负责数据采集、主题抽取、情感分析等任务。目的是克服用户打分和评论不一致,实时对在线民宿的满意度评测,包含在线评论采集和情感可视化分析。搭建了百度地图POI查询入口,可以进行自动化的批量查询 POI 信息的功能;构建了基于在线民宿语料的 LDA 自动主题聚类模型,利用主题中心词能找出对应的主题属性字典;以用户打分作为标注,然后 litNlp 自带的字符级 TextCNN 进行情感分析,将情感分类概率分布作为情感趋势,最后通过 POI 热力图的方式对不同地域的民宿满意度进行展示。软件版本请见链接。
