As the amount of information on the Web continues to expand, the way people access information has also changed. Instead of searching for information in paper books or libraries, people are now searching for relevant information on the Web. However, the amount of data on the Web is so large that it is almost impossible to construct an effective data warehouse to replicate, store and integrate all the data on the Web, and there is neither a unified category code nor an effective organisation of indexing in such a large collection of data, which makes content management and information filtering on the Web increasingly difficult and important. In traditional Web applications there are a large number of redundant words, syntax and other problems that make it impossible to use computers to extract useful information accurately and efficiently, so how to effectively use the available resources is one of the urgent and pressing issues that need to be addressed. Therefore, this paper explores Web text clustering based on the DBSCAN optimization algorithm.
The energy consumption of sewage treatment(ST) process is relatively large. Reasonable process design can reduce energy consumption in an appropriate amount. Reasonable control technology can make up for the deficiency of process design or reduce the difficulty of process realization. Reasonable control can also reduce energy consumption and improve water quality. In this paper, an ACS for ST process is designed, and an improved particle swarm optimization(PSO) algorithm is introduced into the system, so that the system can predict key variables such as BOD and COD that affect the treatment process during sewage treatment, and compare the improved algorithms such as HPSO and SPSO with Predictive performance of the underlying particle swarm algorithm. In order to test the sewage control effect of the system designed in this paper, five key indicators that can reflect water quality are measured, and the measured values are compared with the national standard limit value. It is found that after using the system for sewage treatment, the discharged pollutants are all In line with national standards.
