First, the significance of information collection
Information collection refers to the preparation of information resources for publishing and production, including information collection and processing. It is the direct and important basis for topic selection planning. The last extension of information collection is the beginning of topic planning.
Second, related technologies
(1) Automatic telephone interview (CATS): In recent years, a built-in voice response technology has been used to replace the traditional research methods and telephone interviews. She used the recording of a professional researcher to read out the questions and answers word by word instead of the interviewer. Respondents can type the answers to closed questions through the dial on the mobile phone, and the answers to open questions are recorded on the tape one by one.
(2) Interactive Computer Assisted Telephone Access (CATS): Interactive Computer Assisted Telephone Access is a "computerized" form of central control telephone access. Every interviewer sits in front of a computer terminal or personal computer. When the interviewee's phone is connected, the interviewer starts the machine to ask questions through one or several keys, and the answers to the questions and multiple-choice questions immediately appear on the screen. This method omits the steps of editing and inputting data.
(3) Computer cabinet research: Computer cabinet research is a direct computer interview and research method similar to a public telephone booth. Computers with touch screens are stored in cabinets that can be moved freely. Computers can design programs to guide complex research and display full-color scanned images (products, store appearance, etc. ), and can also play audio and TV images.
