What Is an Intelligent Agent?

Intelligent agent (intelligent agent) is a program that collects information or executes services on a regular basis. It does not require human intervention, has high intelligence and autonomous learning, and can actively collect the most users through an intelligent proxy server according to user-defined criteria. Interested information, and then use the agent communication protocol to push the processed information to the user on time, and can infer the user's intention, independently formulate, adjust and execute the work plan.

In the Internet, typically, an intelligent agent can search the entire Internet or a part of it according to the parameters provided, and collect the information you are interested in. Intelligent agents are sometimes called bots, short for robots.

Some agents can also personalize information on the website based on registration information and usage analysis. Other types of agents include spot monitoring, and then let you know when the website is updated or find other things. The analysis agent not only collects information, but also organizes and provides information for you.

The method by which the agent passes information to you is often called the push technology. ^[1]

Hayers Roth of Stanford University in the United States believes that "intelligent agents continuously perform three functions: perception of dynamic conditions in the environment; execution of actions affecting the environment; reasoning to interpret perceptual information, solving problems, generating reasoning and determining actions." He believes that agents Reasoning and planning should be performed during the action selection process. Generally, intelligent agents in the broad sense include humans,

Intelligent agents can be divided into four basic types: information agents; detection and monitoring agents; data mining agents; user agents or personal agents.

Intelligent agent technology is

Intelligent agent technology was originally applied in the commercial field. With the rapid development of communication technology and network information technology, its features and functions have been continuously expanded. It is mainly used in the research and development of intelligent search agents, digital libraries, e-commerce and distance education And other fields. ^[2]

Research and Development of Intelligent Search Agent

With the continuous development of computer artificial intelligence research, intelligent agent technology with features such as intelligence, agency, adaptability, and learning has moved from the experimental stage to practical application. At present, intelligent search agents have become the core technology of network information retrieval. Intelligent search agent is a specific field of network information retrieval applied by intelligent agent technology. It is a forward-looking and advanced network information retrieval method at present, and aims to provide users with rapid, accurate and convenient network information retrieval services. Compared with traditional search engines, intelligent search agents have their own distinctive features.

Application of Intelligent Agent Technology in Digital Library

Digital libraries are also a new field of research and development in the field of library and information sciences at home and abroad in recent years. Digital libraries are massive "information spaces" that can meet the needs of distributed object-oriented information query. It takes the construction of network information resources as the core, and uses modern information technology achievements such as artificial intelligence, mass information access, multimedia production and transmission, automatic indexing, digital copyright protection, and e-commerce to form a super-large-scale, distributed system that is easy to use, Knowledge center that has no space-time restrictions and can achieve seamless linking and intelligent retrieval across libraries. Intelligent agent technology also plays a very important role in digital libraries.
