Typically, techniques that benefit effectiveness of information retrieval (IR) systems have a negative impact on efficiency. Yet, with the large scale of Web search engines, there is a need to deploy efficient query processing techniques to reduce the cost of the infrastructure required. The ...
As I writhed about I could see in his eyes that curiosity I had so often noted, that wonder and perplexity, that questing, that everlasting query of his as to what it was all about. View in context For processing a spatio-temporal query, IR-tree collects information from all the wireless...
Tolerant retrieval and query processing in search engine can enhance the robustness and users feel convenient. Based on the similar comparison between the right terms and terms proposed by users, the proposed approach can not only tolerant misspelling, but also present relevant retrieval advice. If ...
The SQL Server Query Optimizer doesn't choose only the execution plan with the lowest resource cost; it chooses the plan that returns results to the user with a reasonable cost in resources and that returns the results the fastest. For example, processing a query in parallel typically uses ...
This pa-per explores the use of knowledge-based semantic relatedness in order to bridge the gap between query and documents. We performed query expansion, with pos-itive effects over some language modeling baselines. 展开 会议名称: International Joint Conference on Natural Language Processing ...
Thus, the details of continuous query processing techniques discussed in previous studies will be addressed separately here. These techniques focus on handling not only the mobile object updates, as well as the data structures used to maintain both queries and query results. 4.2.2.1 Continuous ...
