摘要: An increasing amount of data is produced in the form text streams − these can be RSS news feeds, TV closed captions, emails, etc. We study problem answering keyword queries on multiple textual streams. define result a query inspired by previous work search static databases. A to combination “sufficiently correlated” each other that collectively contain all keywords within specified time span. On algorithmic side, this paper we focus component continuously monitoring and outputting results as soon they are available.
