Description

一种基于CIWN-II的互联网交易平台不确定性评价滤波系统
技术领域
本发明涉及互联网交易平台领域，具体涉及一种基于CIWN-II的互联网交易平台不确定性评价滤波系统。
背景技术
随着互联网技术的发展，互联网交易覆盖面逐渐变得广泛，这种商业模式以互联网为平台，通过即时通讯方便不同地方人的交流，脱离了时间与空间上的限制。近年来，在世界发达国家和地区，互联网交易在规模和数量上都呈现高速发展的趋势。
但是由于电商平台上这种非面对面交易存在很多不确定性，比如：
1)消费者对于网络上的商品的了解只能通过图片和文字描述来完成，而有些商品的描述语言模棱两可，容易使人对商品的认识产生歧义，这就使“网购”变成一件有风险的事情；
2)当我们网上购物时，可能会出现服务态度差、配送速度慢等问题，但有的买家却因此迁怒商品本身；
3)售后服务问题，有时商家不积极的售后服务也会令买家厌恶到商品本身。
电商交易的前提就是信任与共识。共识即卖家与各个买家在对商品的价格及价值产生相同的认可程度。一些电商交易平台也采取了措施来建立共识比如利用商品评价使消费者更好地了解商品本身。
利用评价来判断商品好坏的方法也存在一定的问题，如：
1)店家付款请人假扮顾客，用以假乱真的购物方式提高网店的排名和销量获取销量及好评吸引顾客。刷单，一般是由店家提供购买费用，帮指定的网店卖家购买商品提高销量和信用度，并填写虚假好评的行为，通过这种方式，网店可以获得较好的搜索排名。比如，在平台搜索时“按销量”搜索，该店铺因为销量大(即便是虚假的)会更容易被买家找到可以虚假提高店铺整体信誉度。
2)电商交易中还存在同行之间的恶意评价；评价方利用“中评”或“差评”对被评价方做出威胁，或提出不合理的要求，如退款、降价等；或因为推荐物流的原因而对被评价人发起的中、差评等类似“恶意差评”的情况。
发明内容
