SALSA算法和PageRank算法四思想介绍

SALSA算法
SALSA algorithm
SALSA算法同样也融合了HITS算法和PageRank算法的综合思想,但是与Hilltop算法的不同之处在于Hilltop算法强调链接查询关系,SALSA算法强调链接权值分配。
SALSA algorithm also combines the HITS algorithm and PageRank algorithm, but the difference between the Hilltop algorithm and the SALSA algorithm is that the Hilltop algorithm emphasizes the link query relationship, and the algorithm emphasizes link weight allocation.
发现一个站点给定一个有效的权值X(可以为1、可以为0.5,不同的搜索引擎值不一样),但是最终我们可以发现,链接他可以多元化吸收站点的权值。比如举个最常见的例子,链接是具备推荐度传播加分,也成为信任值。比如市长(权威站点,如腾讯网)说我是村长和普通人(普通站点)说我是村长的可信度明显是前者。
Found a site given a valid weight X (can be 1, can be 0.5, different search engine value is not the same), but in the end we can find that links, he can absorb the weight of the site diversity. For example, one of the most common examples is that links have recommendations, spread points, and trust values. For example, the mayor (authority site, such as Tencent network), said I was the village head and ordinary people (ordinary site), said I was mayor of the credibility is obviously the former.
但是市长也不是天生是市长,也是由于他背后有大量的普通人给与投票形成的权威性。所以我们常常所听到的优质外链权值传递更高其实来至于SALSA算法本身,并不是所谓的爱站、站长工具这种虚拟权重。
But the mayor is not born mayor, but also because he has a large number of ordinary people to vote on the authority of the formation. So we often hear the quality of the chain weight transfer higher, in fact, as for the SALSA algorithm itself, not the so-called love station, webmaster tools this virtual weight.
如果用这类工具来交换友情链接,稍微有点经验的人都知道是一个中看不中用的链接。当然,如何去识别交换链接的站点网页评分可以通过链接分析工具ahres(该工具收费,工具计算规则是采用了PageRank算法进行,是全球外链工具里面比较好的一款实时分析工具)进行查询。

If you use this type of tool to exchange links, a little bit of experience is known to be a useless link. Of course, how to identify the web site can exchange links through link analysis tools ahres score (the tool charge calculation tools rule is adopted PageRank algorithm, is a global chain of good tools inside a real-time query analysis tool).

PageRank算法
PageRank algorithm
算法思想:PageRank算法来自于谷歌搜索引擎,虽然对于国内搜索引擎来说该算法不一定100%准确,但是绝对有参考价值。PageRank算法的核心思想强调两个点,一个是链接数量假设原则,另一个则是链接质量假设原则。但是该算法仅仅是链接分析算法,和用户查询无关,所以PageRank算法通常不会单独使用,因为缺陷较大。
Algorithm thinking: PageRank algorithm comes from Google search engine, although for domestic search engine, the algorithm is not necessarily 100% accurate, but there is definitely reference value. The core idea of the PageRank algorithm emphasizes two points, one is the number of links hypothesis, and the other is the link quality hypothesis. However, the algorithm is only a link analysis algorithm and has nothing to do with user queries, so the PageRank algorithm is usually not used alone because of a large defect.
