演講摘要: In this talk I will first give an overview on web search (or web IR). I will introduce the major tasks of web search: relevance ranking, importance ranking, web page understanding, query understanding, crawling, indexing, anti-spam, search result presentation and search log data mining. I will then indicate that statistical learning technologies can be employed to perform the tasks, including classification, clustering, learning to rank, link analysis, and information extraction.
