In information retrieval (IR) and search engines, the quality of an answer strongly depends on how well the user’s query is correctly understood. In this talk, I will distinguish several levels of query understanding, from basic term weighting to search intent understanding and question answering. I will describe the general approaches and the progress made in this direction. Although the current search engines often exhibit some level of intelligence in understanding user’s queries and search intents, we are still far from the ultimate goal of true understanding. I will discuss about the key issues to be addressed for this ultimate goal.
