Exactly one year ago, Google Corporation shared with the public its scientific note on its new Google-SMITH search algorithm. Smith was a follower of the Bert algorithm already running at that time. And was also intended to work with content. The difference from Burt was in the volume of the text; SMITH analyzed the keys “with tails” found in voluminous articles and notes. The published tests made it clear that the new search engine bypasses the previously released Bert in many respects (in terms of processing long documents and queries). However, just a month later, on his official Twitter account, Danny Sullivan announced that Smith is one of the many products the company is working on and is not currently launched. The public actively discussed the article and Sullivan’s comment for a couple of months. Still, due to the lack of information from the corporation, all the activity came to naught until December 2021.
How SMITH Works and Its Main Differences
The development vector chosen by search engines several years ago is actively developing. At that time, analyzing all requests and sites using neural networks, which seemed unrealistic, no longer seemed so romantic. New algorithms are a direct confirmation of this. So what is the difference between the new services? The main difference lies in the amount of text that SMITH can analyze. The last mention refers to the length of 2048 characters (before that, the maximum size was only 512).
Google-SMITH habitually divides the text into blocks, each including 1-2 sentences. After that, the algorithm compares each block with the search phrase, looking for a match between the key and the text. Then, work is carried out with all unions and the entire text by a similar principle. Departure from the old doctrine of searching for only the critical query in the text, without working out blocks and analyzing the document, opens up a new step in preparing content and creating websites. Generally, to form equal unions with text (for further processing), the program is based on the GSF (greedy sentence filling) method, which uses the point size of the block. Each “section” usually contains one whole sentence. GSF transfers the remaining part to another block in cases where its length is considerable.
Differences SMITH and BERT
The main difference, in addition to the specified amount of processed information, is the different models of training programs. For example, Smith has a system for analyzing and predicting the hidden meaning in a sentence and comparison with another part (fragment) of content. Such an essential and significant goal required the analysis of large libraries, among which the ACL Anthology Network and Wiki are mentioned. The document bases of these resources formed the basis of SMITH training. Burt’s task, in turn, was to find hidden words in a sentence and predict some of the words in a random selection. This was the basis for all the training of the current algorithm.
Impact on issuance
Both Bert and SMITH aim to understand a user request’s intent better. Google wants to show relevant results to the user, whether the query used slang or not, whether it’s technical language or colloquial speech. Vast arrays of information studied by search algorithms make it possible to understand the everyday lexicon. Currently, Google is working on extensive coverage (of the entire document). How does this affect search results? The impact on commercial queries is minimal (they rarely use slang, and the content is most relevant to keywords). Still, in standard and informational questions, the work of the new algorithm is already visible.
