Research Of Search Engine Incident Response Timeliness Of The Evaluation Method

Search engines as a primary tool for human access to information, it will directly determine people's access to information accuracy, speed and cost. Current research directed to the search engine in terms of timeliness has been carried out for many years, but there are some problems, one is little research, two research methods not described in detail. Nowadays people for time-critical information is increasingly high, especially for emergencies, people are more concerned about the state of development of events, eager to learn every step of the progress of events, a good search engine, inclusion and for emergencies show must have a good strategy in order to meet the needs of users.In this paper, the search engine timeliness of in-depth study, using statistical language model extraction based query methods, propose an efficient and feasible timeliness kpi calculation algorithm. Firstly, the theoretical basis of this paper introduces the method of aging assessment, analyzes the significance and importance of breaking news events based on the timeliness of assessments. Secondly, the use of excavated emergencies sudden burst query query statistical language model based on mining methods, different search engine results pages get the same query, and analyze the results page to get the results to show the location and the time factor information, calculate the timeliness kpi indicators using different search engines timeliness kpi calculation. Finally, the design and development of the timeliness of the search engine evaluation model based monitoring system emergencies.Kpi timeliness of the proposed calculation method has been applied commercially, can provide some directional suggestions to improve search engine and improved services, the theory put forward a set of simple, suitable for emergency operation of the cluster timeliness monitoring method, researchers for the relevant reference.
