“Stop words” is a term used in the realm of search engine optimization^[1] (SEO) and data processing. These are common function words like ‘and’, ’the’, ‘in’, which are often removed from queries to save space and time in data processing. This concept has roots in creating concordances and has been developed over time by various researchers. Notably, Hans Peter Luhn is credited with coining the phrase and C.J. Van Rijsbergen proposed the first standardized list of these words. Today, the use of stop words has evolved with the advancement of machine learning^[2]. While they were initially removed for faster query processing, search engines like Google^[3] now advise against worrying about stop words and encourage writing in a natural way. They are still used in specific circumstances like narrowing search results. This concept is related to other topics like concept mining, information extraction, and query expansion.

Terms definitions

1. ↑ search engine optimization. Search engine optimization, commonly referred to as SEO, is a critical digital marketing strategy. Originating in the mid-90s, SEO involves enhancing websites to achieve higher rankings on search engine results pages. This process is essential for increasing web traffic and converting visitors into customers. SEO employs various techniques, including page design, keyword optimization, and content updates, to enhance a website's visibility. It also involves the use of tools for monitoring and adapting to search engine updates. SEO practices range from ethical 'white hat' methods to the disapproved 'black hat' techniques, with 'grey hat' straddling both. While SEO isn't suitable for all websites, its effectiveness in internet marketing campaigns cannot be underestimated. Recent industry trends such as mobile web usage surpassing desktop usage highlight the evolving landscape of SEO.

2. ↑ machine learning. Machine learning, a term coined by Arthur Samuel in 1959, is a field of study that originated from the pursuit of artificial intelligence. It employs techniques that allow computers to improve their performance over time through experience. This learning process often mimics the human cognitive process. Machine learning applies to various areas such as natural language processing, computer vision, and speech recognition. It also finds use in practical sectors like agriculture, medicine, and business for predictive analytics. Theoretical frameworks such as the Probably Approximately Correct learning and concepts like data mining and mathematical optimization form the foundation of machine learning. Specialized techniques include supervised and unsupervised learning, reinforcement learning, and dimensionality reduction, among others.

Stop word (Wikipedia)

Stop words are the words in a stop list (or stoplist or negative dictionary) which are filtered out (i.e. stopped) before or after processing of natural language data (text) because they are deemed insignificant. There is no single universal list of stop words used by all natural language processing tools, nor any agreed upon rules for identifying stop words, and indeed not all tools even use such a list. Therefore, any group of words can be chosen as the stop words for a given purpose. The "general trend in [information retrieval] systems over time has been from standard use of quite large stop lists (200–300 terms) to very small stop lists (7–12 terms) to no stop list whatsoever".
