Mooers's law

Last updated

Mooers's law is a comment about the use of information retrieval systems made by the American computer scientist Calvin Mooers in 1959:

Contents

An information retrieval system will tend not to be used whenever it is more painful and troublesome for a customer to have information than for him not to have it.

Original interpretation

Mooers argued that information is at risk of languishing unused due not only on the effort required to assimilate it but also to any impliciations of the information that may conflict with the user's prior information. In learning new information, a user may end up proving their work incorrect or irrelevant. Mooers argued that users prefer to remain in a state of safety in which new information is ignored in an attempt to save potential embarrassment or reprisal from supervisors. [2]

Out-of-context interpretation

The more common interpretation of Mooers's law is similar to Zipf's principle of least effort. It emphasizes the amount of effort needed to use and understand an information retrieval system before the information seeker gives up; it is often paraphrased to increase the focus on the retrieval system:

The more difficult and time consuming it is for a customer to use an information system, the less likely it is that he will use that information system.

J. Michael Pemberton

Mooers's Law tells us that information will be used in direct proportion to how easy it is to obtain.

Roger K. Summit [1]

In this interpretation, "painful and troublesome" comes from using the retrieval system.

Information retrieval (IR) in computing and information science is the process of obtaining information system resources that are relevant to an information need from a collection of those resources. Searches can be based on full-text or other content-based indexing. Information retrieval is the science of searching for information in a document, searching for documents themselves, and also searching for the metadata that describes data, and for databases of texts, images or sounds.

A document management system (DMS) is usually a computerized system used to store, share, track and manage files or documents. Some systems include history tracking where a log of the various versions created and modified by different users is recorded. The term has some overlap with the concepts of content management systems. It is often viewed as a component of enterprise content management (ECM) systems and related to digital asset management, document imaging, workflow systems and records management systems.

Information science is an academic field which is primarily concerned with analysis, collection, classification, manipulation, storage, retrieval, movement, dissemination, and protection of information. Practitioners within and outside the field study the application and the usage of knowledge in organizations in addition to the interaction between people, organizations, and any existing information systems with the aim of creating, replacing, improving, or understanding the information systems.

In information science and information retrieval, relevance denotes how well a retrieved document or set of documents meets the information need of the user. Relevance may include concerns such as timeliness, authority or novelty of the result.

<span class="mw-page-title-main">History of software engineering</span>

The history of software engineering begins around the 1960s. Writing software has evolved into a profession concerned with how best to maximize the quality of software and of how to create it. Quality can refer to how maintainable software is, to its stability, speed, usability, testability, readability, size, cost, security, and number of flaws or "bugs", as well as to less measurable qualities like elegance, conciseness, and customer satisfaction, among many other attributes. How best to create high quality software is a separate and controversial problem covering software design principles, so-called "best practices" for writing code, as well as broader management issues such as optimal team size, process, how best to deliver software on time and as quickly as possible, work-place "culture", hiring practices, and so forth. All this falls under the broad rubric of software engineering.

Findability is the ease with which information contained on a website can be found, both from outside the website and by users already on the website. Although findability has relevance outside the World Wide Web, the term is usually used in that context. Most relevant websites do not come up in the top results because designers and engineers do not cater to the way ranking algorithms work currently. Its importance can be determined from the first law of e-commerce, which states "If the user can’t find the product, the user can’t buy the product." As of December 2014, out of 10.3 billion monthly Google searches by Internet users in the United States, an estimated 78% are made to research products and services online.

Human–computer information retrieval (HCIR) is the study and engineering of information retrieval techniques that bring human intelligence into the search process. It combines the fields of human-computer interaction (HCI) and information retrieval (IR) and creates systems that improve search by taking into account the human context, or through a multi-step search process that provides the opportunity for human feedback.
