Modern society is often called information. Indeed, we increasingly become dependent on various sources of information and news. They affect our way of life, habits, relationships. And that impact is only growing. Modern man is more and more of their resources (money, time, energy) spent to meet the information needs, their own and others. Relation to information of different kinds becomes the cornerstone of the difference between the generations. Will discuss what the media needs, what are they and how satisfied.

information needs

Concept requirements

People are constantly in any need. The feeling of deficiency always perceived as discomfort. And in any case, be it lack of food or the approval of others, the need is feeling of inconvenience, which I want to overcome. And the stronger the feeling of lack of something, the more likely people will find a way to get rid of it. This deficit condition is called need. Our physiology controls the life-support systems and through demand signals that need to “deliver” in the body: food, water, information. A requirement of the state informs the person about the change of functioning of some systems, and it entails the execution of any action. Poverty and needs are the main motivating factor in human behavior. They do not allow us to rest on our laurels and are the basis of all living beings. It should be understood that the need is not equal to the requirement. Only when man realizes the need for something, then there is a need. The need always has an objective basis, and need – subjective.

In humans, there are options to relieve discomfort, it builds the needs into a hierarchy of importance, here, and manifest specific personality characteristics. In this regard, the process of formation of requirements manageable. The society forms a welcome and tabouret unwanted desires. So, until recently people did not hesitate to satisfy hunger with wheat bread. But today, when there was a huge propaganda work to discredit the fast carbs, we often choose to relieve the same need for food is not white, but black or whole wheat bread. In modern society is the management of behaviour is often carried out through information needs. Man gets information about how it is better to satisfy their desires.

Types of requirements

Due To the fact that the needs are extremely diverse, there are several approaches to their classification. Most compelling are the following. In the first case, the requirements are divided into three large groups: biological, social and ideal. Human biology is relevant to many needs: he needs food, water, sleep, reproduction, safety. Without this, human life is exposed to great risks, so the physiological needs are satisfied first. Although features of human personality are that the individual is free to choose what need to remove first. We know that a Mature person can indulge in biologically significant things in the name of spiritual needs. For example, during the war in besieged Leningrad people maintain a strategic stock of grain, but suffered terrible torments of hunger.

Social needs associated with existence in the community, these include belonging to a group, recognition, self-assertion, leadership, respect, love, affection, etc.

The third group includes the so-called higher order needs: self-actualization, self-esteem, aesthetic and cognitive needs, the meaning of life. These desires, according to A. Maslow, are at the top of the pyramid and met once as a whole dropped the first and second level. Although the man is certainly more complex than any of the schemes and in some cases he is able to sacrifice biology in the name of ideals. Actually, in this he differs from the animal. To meet every kind of needs, human needs a variety of information. Use of information as a tool to meet the needs – this is a specific human way of conducting business.

The Second approach divides requirements into those that need to save something for growth.

The Concept of information

The world around us – large information base. Her infinite variety leads to complexity of definition of this concept. In the most General sense, information understand a variety of information about the environment in various forms of representation. These data are the object of storage, processing, copying, transfer, processing, use. The term “information” is used in many fields: communication theory, Cybernetics, and Informatics, bibliography and others. In each case, the concept acquires an additional value.

The Specificity of information is that it can be presented in a variety of forms. Including in the form of texts, charts, images, radio waves, sound and light signals, gestures and facial expressions, energy, and nerve impulses, smell, taste, chromosomes. And it only forms detectedthe existence of information. Scientists suggest that in the future, when there will be more information will be found and new forms.

Characteristics of such diverse phenomena usually given through the description of its properties. These include:

1. Completeness. This property is associated with understanding. If its a message meaning can be decoded, the information is considered complete.

2. Reliability. Information should reflect a true and not contrived or distorted the situation.

3. Objectivity. Information do not change its meaning depending on the individual perceiving them.

4. Accuracy. The information should reflect the current status of objects and phenomena.

5. Accessibility. It should match the level of understanding of the recipient.

6. Brevity. Transfer information should be as briefly as possible, but without sacrificing clarity.

There are other properties such as value, urgency, etc.

classified information

Types of information

In the most General form can be divided into two big groups: objective and subjective. The first group is associated with the ability of real objects to transmit information that does not change depending on the perception of the subject. And the second, opposite, changes its characteristics in accordance with the perceiver or the transmitting person. For example, information about the chemical composition of water does not vary, one she had not considered. But the official information of the party about their activities can change its meaning depending on who perceives it.

Also can be divided into analog and digital. First – it is a continuous form of existence of information. For example, the human body temperature is constant (healthy) all year round and from year to year. The second type, by contrast, is associated with the discontinuity, temporal dynamics of information flow. For example, statistics of the crop changes from year to year.

According to the form of presentation is customary to provide graphical, textual, visual, audio and video, numeric information.

According to the degree of availability of a wide circle of people stands out General, restricted and secret information. In this series there are also data for which there is no form of storage: tactile, sensory, gustatory, etc.

At the place of origin of information to allocate the basic, biological and social information.

For the purpose it can be classified as personal, mass and specific, i.e. created for a specific group of people.

Also released background information as a separate functional form.

The Concept of information needs

In General terms, the information needs understand the need for information about reality that can be useful for performing any action. From childhood to the adoption of any decisions man requires a variety of information. In the initial stages of human development they provide surrounding: family, friends, teachers. But there comes a time when people need information they cannot obtain from their usual sources (from memory, from the inner circle), and then there is the same deficit state which motivates to realize new needs – information. People feel a mismatch between the available and required information, which forces them to search behavior. It is from this gap between knowledge and ignorance grow scientific information needs. Once people wondered about where everything came from. In response to the request first appears as an explanatory mythology, but gradually knowledge of the world increases, and in response to new issues emerging science, philosophy, etc.

The Term "information needs" appears only in the mid-20th century. He is introduced in the framework of the Sciences of information systems. But this does not mean that before this the needs the people had. It is an essential part of cognitive performance and appears of a certain age. Every child is a child asking questions, exploring the world. And that's the moment when loved ones cease to satisfy, there is a recognized need to find new knowledge.

Properties implementation

Journalist Robert Taylor said that information needs have a number of distinctive characteristics. They are always associated with cognitive activity and language. Out of these systems they can not exist. Properties of these requirements directly derive from the properties information. Any information needed for the life of the people, should be accurate, complete, valuable, etc., People who need background experience to their own needs, and this is the first property – they are subjective. They are also flexible: the person usually does not impose very strict requirements on the source of information when it satisfies the main criteria of assessing the quality of information you receive. He is ready to take any available and suitable method to satisfy their information needs. Also these needs is characteristic of irreversibility. Once established, they do not disappear, but only grow. However, for some time, the person may postpone the satisfaction of these needs if aktualisierte any other. Another property – it's a potential neudovletvorennosti. Knowledge is limitless, learning somethingnew about the object, the person may begin to experience the need for additional information, and this process has no end. The latter property is due to the motivating function of needs. The need for information is always an incentive for some human activities.

the process of meeting the information needs

Classification

There are several approaches to the selection of varieties needs for additional knowledge. Traditionally, the types of information needs define their main characteristics. There is a philosophy in which they are divided into objective and subjective. First exist outside of personal needs and desires, and the second – depend on them. But this approach is incorrect. As information needs are always the result of personal experiences of the person, they cannot be produced by the objective environment. There is a practice of allocating collective, public and individual needs for information and knowledge.

Public arise as a social request, he has no specific groups of actors. For example, such can be called needs knowledge about the environment, about the situation in the country and the world, etc.

The Collective belong to the specific target groups according to various criteria. For example, doctors need to know about new diseases, epidemics, methods of treatment, etc.

And individual, respectively, occur in individuals as a result of their practical activities.

There are Also attempts to highlight the types of information needs, both real and perceived, expressed and latent, permanent and temporary, professional and non-professional. Some researchers propose to divide needs into groups according to the type of information: visual, textual, methodological, etc. There is a proposal to classify them, focusing on the profession and occupation of the subject: scientific, reference, educational, medical, pedagogical, etc.

There is a relatively universal classification, within which there are organic, spiritual, and professional information needs. First – different sensory information about the environment. Second – the need for different social media. Including, for example, this includes attention to the rumors, the need to know news, etc. Third – this is the knowledge which man needs for the conduct of their professional activities. None of the classifications is not comprehensive and exhaustive. Therefore, the search in this direction will long continue.

Stages of a process to meet information needs

Feeling a need for information, a person commits certain actions that may be stowed in a relatively typical pattern. In General, the process of satisfying information needs is divided into several stages:

1. The emergence of motive. The person begins to experience discomfort from the appearance of discrepancies between existing and needed knowledge.

2. Awareness of the needs. The subject begins to formulate a question that will look for the answer. Information requests may vary in clarity and certainty. Generally there slaboosveschennyh request when the person cannot verbalize their need; conscious, but not ready - in this case, the man realizes that he wants to learn but in verbalization of the query he needs expert help; formulated the question of when a person can explain what he wants to know.

3. The search program. Develops the strategy is “getting” necessary knowledge, identifies sources of information.

4. Search behavior. The man turns toward the source of the information, if necessary – to a few, until you drop the state of cognitive deficit.

Ways to meet needs information

Emerging from lack of information, modern man can be eliminated in different ways. There is a rough algorithm, which is followed by people wanting to learn anything. First stage-internal search. It is human nature in the first place to turn to available resources. First, he tries to remember what he knows, to make comparisons and analogies. If this search has not led to satisfaction, the person turns for help to his “inner circle». That is asking relatives, colleagues and acquaintances. The information received from them it compares with their internal cognitive resources, verify. If this step does not give the desired result, then the person goes to an external search. It is very diverse and virtually unlimited. The person tries to obtain access to information that is stored in some “banks’. Today this role is increasingly provided online. And recently the man went to the library. External sources of information are reputable people, including experts, specialists, experienced people. You can access them personally or through various means of communication: Internet, mail, phone. Secret information can be searched through special channels: files, closing database. Another source of information are the fundsmedia. They often try to anticipate potential information needs of society and to provide people with information. For example, any news release is not without weather. Because people always interested in this information. In some cases the source of information is the educational organization. So, if a person lacks knowledge in some field, he can go on courses and gain the necessary knowledge.

official information

Find information

With the advent of automated information systems and with the invention of search engines, the term "information retrieval" gets some new color. It refers to the process of finding the necessary information in the stream of unstructured documents. This activity implements a special program called a search engine. A user wishing to satisfy their information need, only need to clearly formulate your request, and the machine will find the necessary information, if they exist in the world wide web. The steps are simple and the same for all:

- awareness of the problem and the wording of the request;

- select the sources of information credible.

- extract the right information from found sources;

- the use of information and evaluation of search results.

search in network

Internet User can use different types of search. Address requires knowledge of the exact source address information (e.g., email address). Semantic search allows you to search the documents to the wrong address or the page name, but by their content. Machine looking for key words and issues page with the greatest coincidence with the search query. Documentary search is characteristic for the systems such as the catalogs of libraries or archives.

Information Needs of modern man

Humanity today becoming more and more dependent on information. For many people, finding information on the Internet – is a daily activity. With this trend associated with the decrease in the impact on society of traditional media-television, radio, press. And the increasing role of electronic media. Online search has greatly simplified the process of obtaining information has made many more sources available. But also there are problems of reliability and quality of information. In the Network each user can be a little media, but to give a proven and valuable information can not all bloggers or authors. Today's society quickly develops new mechanisms of regulation of electronic media, published new laws, the search for social regulators, which would allow to protect the privacy of the person to comply with the norms of accepted morals.
