(3) (roBOT) A program that performs a repetitive function 24/7 or waits in the background to be triggered by some event (time of day, receipt of data, etc.). The term bot is used for myriad "intelligent agents" on the Web, and it is estimated that more than half the Web's traffic comes from bots and not humans. A bot can be programmed to do almost anything from posting a message to starting up or closing down other software processes.

A bot is often used to find information. For example, a "spider" is a search engine bot that "crawls" the Web 24/7 looking for Web pages. A bot can also run in a user's machine or in a server in a private network. See social bot, scalper bot, trader bot, spambot, chatbot, agent, CAPTCHA and trolling.

Internet troll

An individual who posts false accusations or inflammatory remarks on social media to promote a cause or to harass someone. The anonymity of such venues enables people to say things they would not say in person, and they often like to ratchet up emotions to generate strong reactions. See patent troll, troll farm, flame war, trolling and cyberSLAPP.

patent troll

An organization that uses its patents to generate revenue without manufacturing the products that the patents pertain to. The patents are often purchased from a third party, which may be bankrupt or no longer interested in bringing the product to market.

Also called a "non-practicing entity" (NPE) or "patent assertion entity" (PAE), which are less denigrating, the patent troll looks for infringers that have invested heavily in the product and often has to threaten them with or actually instigate a lawsuit in order to obtain licensing revenues. Companies that are involved in the business that the patent covers may indeed sue others for patent infringement, but that does not make them a patent troll. A patent troll is a holding company that buys patents based on their potential profitability if enforced. See Internet troll.
