# Academic conference

An academic conference or scientific conference (also congress, symposium, workshop, or meeting) is an event for researchers (not necessarily academics) to present and discuss their scholarly work. Together with academic or scientific journals and preprint archives, conferences provide an important channel for exchange of information between researchers. Further benefits of participating in academic conferences include learning effects in terms of presentation skills and "academic habitus", receiving feedback from peers for one's own research, the possibility to engage in informal communication with peers about work opportunities and collaborations, and getting an overview of current research in one or more disciplines.
The first international academic conferences and congresses appeared in 19th century.

## Overview

Conferences usually encompass various presentations. They tend to be short and concise, with a time span of about 10 to 30 minutes; presentations are usually followed by a discussion. The work may be bundled in written form as academic papers and published as the conference proceedings.
Usually a conference will include keynote speakers (often, scholars of some standing, but sometimes individuals from outside academia). The keynote lecture is often longer, lasting sometimes up to an hour and a half, particularly if there are several keynote speakers on a panel.
In addition to presentations, conferences also feature panel discussions, round tables on various issues, poster sessions and workshops. Some conferences take more interactive formats, such as the participant driven "unconference" or various conversational formats.

### Format

Academic conferences have been held in three general formats: in-person, virtual or online and hybrid (in-person and virtual). Conferences have traditionally been organized in-person. Since the COVID-19 pandemic many conferences have either temporarily or permanently switched to a virtual or hybrid format. Some virtual conferences involve both asynchronous and synchronous formats. For example, there is a mix of pre-recorded and live presentations.
Because virtual or hybrid events allow people from different time zones to participate simultaneously, some will have to participate during their night-time. Some virtual conferences try to mitigate this issue by alternating their schedule in a way so that everyone has the chance to participate at day time at least once.

### Presentations

Prospective presenters are usually asked to submit a short abstract of their presentation, which will be reviewed before the presentation is accepted for the meeting. Some organizers, and therefore disciplines require presenters to submit a paper, which is peer reviewed by members of the program committee or referees chosen by them.
In some disciplines, such as English and other languages, it is common for presenters to read from a prepared script. In other disciplines such as the sciences, presenters usually base their talk around a visual presentation that displays key figures and research results.

### Size

A large meeting will usually be called a conference, while a smaller is termed a workshop. They might be single track or multiple track, where the former has only one session at a time, while a multiple track meeting has several parallel sessions with speakers in separate rooms speaking at the same time. However, there are no commonly shared definitions even within disciplines for each event type. There might be no conceivable difference between a symposium, a congress or a conference.
The larger the conference, the more likely it is that academic publishing houses may set up displays. Large conferences also may have a career and job search and interview activities.
At some conferences, social or entertainment activities such as tours and receptions can be part of the program. Business meetings for learned societies, interest groups, or affinity groups can also be part of the conference activities.

### Types

Academic conferences typically fall into three categories:
* the themed conference, small conferences organized around a particular topic;
* the general conference, a conference with a wider focus, with sessions on a wide variety of topics. These conferences are often organized by regional, national, or international learned societies, and held annually or on some other regular basis.
* the professional conference, large conferences not limited to academics but with academically related issues.

### Infrastructure

Increasing numbers of amplified conferences are being provided which exploit the potential of WiFi networks and mobile devices in order to enable remote participants to contribute to discussions and listen to ideas.
Advanced technology for meeting with any yet unknown person in a conference is performed by active RFID that may indicate willfully identified and relatively located upon approach via electronic tags.

## Organization

Conferences are usually organized either by a scientific society or by a group of researchers with a common interest. Larger meetings may be handled on behalf of the scientific society by a Professional Conference Organiser or PCO.
The meeting is announced by way of a Call For Papers (CFP) or a Call For Abstracts, which is sent to prospective presenters and explains how to submit their abstracts or papers. It describes the broad theme and lists the meeting's topics and formalities such as what kind of abstract (summary) or paper has to be submitted, to whom, and by what deadline. A CFP is usually distributed using a mailing list or on specialized online services such as Call for Papers (CFPs) Index. Contributions are usually submitted using an online abstract or paper management service such as Submit A Manuscript or Conference Submission system.

## Predatory conferences

Predatory conferences or predatory meetings are meetings set up to appear as legitimate scientific conferences but which are exploitative as they do not provide proper editorial control over presentations, and advertising can include claims of involvement of prominent academics who are, in fact, uninvolved. They are an expansion of the predatory publishing business model, which involves the creation of academic publications built around an exploitative business model that generally involves charging publication fees to authors without providing the editorial and publishing services associated with legitimate journals. BIT Life Sciences and SCIgen are some of the conferences labeled as predatory.

## Environmental impact

Academic conferences are criticized for being environmentally unfriendly, due to the amount of airplane traffic generated by them. A correspondence on Nature.com points out the "paradox of needing to fly to conferences" despite increased calls for sustainability by environmental scientists. The academic community's carbon footprint is comprised in large parts by emissions caused by air travel. Few conferences enacted practices to reduce their environmental impact by 2017, despite guidelines being widely available: An analysis of academic conferences taking place in 2016 showed that only 4% of 116 conferences sampled offered carbon offset options and only 9% of these conferences implemented any form of action to their reduce environmental impact. More conferences included the use of teleconferencing after the COVID-19 pandemic.

## Critique of in-person conferences

In-person conferences suffer from a number of issues. Most importantly, they are fostering the existing social inequality in academia due to their inaccessibility for researchers from low income countries, researchers with care duties or researchers facing visa restrictions.
