接着经过简单的 filtering 和 parsing 去掉不关心的数据,比如对于微博的话题来说,某一些词是小词,或者是我们不希望成为话题的词;而某一些近似词可以合并。完成以后数据有两个去向,一个是右侧的即时统计,一个是持久化到下方的数据库中(这个数据库可以是 Redis 这样的 KV 数据库)。 对于每一个词,经过 hash 以后,...

It includes a top-k query processing algorithm that works on the encrypted data of the buckets, and returns a set that contains the encrypted top-k results. It also has a filtering algorithm that efficiently eliminates the false positives in the server side. We implemented BuckTop, and ...
There exist even simple relational queries for which the exact probability computation is #P-hard. Consequently, if we are only interested in the k highest ranked tuples, then an efficient pre-filtering can reduce the computation time significantly. In this work we present a top-k filter which...

Given a data set P on a road network and a query point q with a set of keywords, an RkBSK query retrieves the points in P that have q as one of answer points for their top-k Boolean spatial keyword queries. We formalize the RkBSK query and then propose filter-and-refinement ...
