数据挖掘技术英语论文

Good evening, ladies and gentlemen. I’m very glad to stand here and give you a short speech. Today I would introduce data mining technology to you. What is the data mining technology and what’s advantage and disadvantage. Now let's talk about this.
Data mining refers to "Extracting implicit unknown valuable information from the data in the past” or “a scientific extracting information from a large amount of data or databases”, In general,it needs strict steps to be taken.including understanding, aquistion, intergration, data cleaning, assumptions and interpretation.
By using these steps, we could get implicit and valuable information from the data. However, in spite of these complete steps, there are still many shortcomings.
First of all, the operator has many problems in its development, such as the target market segmentation is not clear,the demand of data mining and evaluation of information is not enough; product planning and management are difficult to meet the customer information needs; the attraction to partners is a little less, and it has not yet formed a win-win value chain; in the level of operation management and business process, the ability of sales team and group informatization service are not adapted to the development of business.In a word, there’re still have a lot of things to be solved. It needs excellent statistics and technology. It
also needs greater power of refining and summary.
Secondly,it’s easy to listen only by the data.”let the data speak”is not wrong, but we should keep it in mind that :next,parties! If the data and tools can solve the problem,what should people do? The data itself can only help analysts to find what are significant results,but it can’t tell you whether the result is right or wrong.So it also requires us to check up the relevant information seriously in case of being cheated by the data. Thirdly, Related to data mining,it also involves privacy issues, for example: an employer can access medical records to screen out those who have diabetes or serious heart disease, which is aimed to reduce the insurance expenditure. However, this approach will lead to ethical and legal issues.
Data mining of government and commerce may involve in the national security or commercial confidentiality issues . It is also a big challenge to confidentiality.. In this aspect,it need the user obey social morals and government strengthen regulation.
All in all,every technology has its own advantages and disadvantages. We need to learn to recognize it and how to use it effectively. In order to create greater benefits for mankind.we still have many things to be discovered about data mining. That’s
all,thanks for your listening.
