(1) Timely
The so-called timeliness is to quickly and sensitively reflect the latest developments in all aspects of the development of the sales market. Information is time-sensitive and its value is inversely proportional to time. Timeliness requires information flow and logistics to be synchronized as much as possible. Because it takes some time to identify, record, transmit and feedback information, there is generally a time lag between information flow and logistics. Minimizing the time when information flow lags behind logistics and improving timeliness is one of the main goals of information collection of online merchants.
(2) accuracy
The so-called accuracy means that the information should truly reflect the objective reality with a small degree of distortion. In online marketing, accurate information is particularly important, because buyers and sellers do not meet directly. Accurate information can lead to correct market decisions. Information distortion, light will delay business opportunities, and heavy will cause huge losses. There are usually three reasons for information distortion: first, the information provided by the source is incomplete and inaccurate; Second, information is disturbed in the process of encoding, decoding and transmission; Third, the information received by the information receiver (mailbox) is biased. In order to reduce the information distortion of network operators, we must improve the management level in the above three links.
(3) Moderate
Moderation means that information should be targeted and purposeful, not aimless. Without information, the marketing activities of enterprises will be completely blind. Too much information will also make marketers at a loss. In today's information age, the amount of information is getting larger and wider, and different management levels put forward different requirements for information. In this case, the collection of online business information must have clear objectives, appropriate methods, and appropriate scope and quantity of information collection.
(4) Economy
"Economy" here refers to how to obtain the necessary information at the lowest cost. Pursuing economic benefits is the center of all economic activities and the principle of collecting online business information. After surfing the Internet, many people often want to copy all the information they can find online, but it was not until the end of the month that they found that the cost of surfing the Internet was very high. It should be clear that we don't have this right, and it is impossible to collect all the information on the Internet. The timeliness, accuracy and appropriateness of information are all required to be based on economy. In addition, to improve the economy, we should also pay attention to making the obtained information play the greatest role.
Faced with difficulties, computer experts and information management experts actively explored, developed a series of retrieval software, and applied it to the management and retrieval of network resources, and made great progress. At present, there are hundreds of retrieval software developed by countries all over the world. China, Hongkong, Taiwan Province Province and Singapore have developed Chinese (GB or GB5) retrieval software, which has made important contributions to promoting the utilization and dissemination of network information. In order to get more accurate content and make full use of these retrieval software, we must use certain skills (such as multi-keyword and Boolean retrieval technology) to narrow the retrieval range.
(1) Clear the search target
To complete effective retrieval, we must first determine what to retrieve. After determining the theme, we should list a list of words related to the retrieved information and a list of words that should be excluded. Next, we should consider which retrieval software to use to obtain more effective retrieval results. If the topic range is narrow, you might as well simply try it with two or three keywords. If you are not sure what you are searching for or the topics you are searching for are wide, you might as well use Yahoo! Search websites and other classified searches, and try to narrow the search scope as much as possible. Many search sites only allow searching on the Web, newsgroups or specific geographical areas.
(2) Rational use of various symbols to improve the retrieval process
In order to make users retrieve content more conveniently and effectively, many retrieval websites allow the use of Boolean operators. Boolean operators provide a way to include or exclude keywords and control how search engines translate keywords. Most retrieval engines provide hints on how to use this engine AND how to input the corresponding forms of Boolean operators in retrieval, but they generally support basic Boolean operations: AND, OR and NOT. When searching, you usually don't need to enter uppercase Boolean operators, but capitalization can visually separate keywords and operators. The symbols and formats used by various retrieval tools are also different.
(3) Make full use of index search engines
Meta-search engine is an engine that searches other directory search websites. The index retrieval engine node formats the query request into an appropriate format acceptable to each directory retrieval node, and then issues the query request. Some index retrieval engines represent the returned results in a unified list.
Index retrieval will take a little more time, but because it can retrieve results from many different sources and finally get good results, it saves time on the whole. When using a search engine, it is best to look at examples or help content. If the wrong morphology is used, the search time will be prolonged and the expected results may not be obtained.
