# Search Algorithms and AI

**Algorithms**

Search engine algorithms are complex mathematical formulas and sets of rules that search engines use to determine the relevance and importance of web pages in response to a user's search query.

&#x20;

When a user enters a search query, algorithms scan Index for web pages and other content that it believes are most relevant to the query. The algorithm then ranks these results based on a variety of factors.

&#x20;

Search engine algorithms are constantly evolving to improve the quality and accuracy of search results. At Timpi we are currently using a number of algorithms which are all based on analytical functions, mathematics and mapping.

&#x20;

&#x20;•         Spellchecker - To check the spelling

&#x20;•         FunctionDetection - Detects if the search term is a calculation or conversion

&#x20;•         LanguageDetection - To detect the language

&#x20;•         KeywordMaker - Identify keywords from text

&#x20;•         SynonymGraph - Create synonyms for keywords

&#x20;•         FlattenGraph - Reduce text to only important information

&#x20;•         WordDelimiterGraph - Word delimiter token filter

&#x20;•         RemoveDuplicates - Removes duplicates from text

&#x20;•         FieldTypeAnalyzer - Identifies field types of an document

&#x20;•         AlternativeTermFinder - Finds alternative terms in conjunction with the synonym Graph&#x20;



**AI**

Artificial Intelligence (AI) is playing an increasingly important role in revolutionizing the search engine technology landscape. With the use of AI, the Timpi search engine is able to understand natural language queries, provide more personalized results, and even predict what users maybe looking for.

&#x20;

One of the primary applications of AI in search engines is machine learning, which involves training algorithms to recognize patterns in vast amounts of data. Timpi uses machine learning to understand user intent, recognize synonyms and related concepts, and personalize results based on user behavior. For instance, Timpi’s Herman algorithm employs machine learning to analyze search queries and determine the most relevant results.

&#x20;

Natural Language Processing (NLP) is another exciting area of AI in search engines. NLP enables search engines to understand human language and context. This technology helps search engines interpret complex queries and identify the most relevant results, even if the query includes misspellings or ambiguous language. For example, when a user searches for "best sushi restaurant near me," TImpi’s search engine understands the intent of the query and displays relevant results based on the user's location.

TImpi’s search engines also use deep learning techniques such as neural networks to analyze and understand the content of web pages. This allows search engines to identify relevant information within text, images, and videos, and rank results accordingly. For example, TImpi’s image search will use deep learning to identify and categorize images based on their content.

&#x20;

In the future Timpi will also use AI to provide voice search capabilities, making it easier for users to search the internet hands-free. Voice search technology uses NLP to understand spoken queries and provides results in a conversational manner.

&#x20;

Timpi's AI is transforming search engine technology, enabling users to find the information they need faster and more accurately than ever before.

&#x20;

The usage of AI in search engines improves the user experience dramatically. Timpi already makes use of several AI models to help users with search terms, or spelling and we will extend the usage of AI models in the future to add even more functionality.



AI models currently used:

* Word vectors represent a significant leap forward in advancing the ability to analyze relationships across words, sentences, or documents. In doing so, they advance technology by providing machines with much more information about words than has previously been possible using traditional representations of words. Word vectors are used to find synonyms for the current word by using nearest neighbors or by defining some notion of “similarity”.&#x20;
* Historical Behavior Synonym - The AI looks at historical search behavior and generates synonym candidates from that. This is particularly useful for Typeahead searches as, in most search engines, synonyms are not compatible with typeahead search. For example, if you want tablet to equal iPad in a query, the prefix search for t , ta , tab , tabl & table will not trigger the expansion on iPad ; Only the tablet query will. Thus, a single new letter in the search bar could totally change the result set, catching users off-guard. This problem can be solved by using a Historical behavior synonym AI model that analyses the input and makes predictions based on previous behavior.
* Lexical Synonyms - These are grammatical synonyms as defined by the rules of the language. The main concept of the relationship between the words is that the words are synonyms like sad and unhappy, benefit and profit. These words show the same concept of using them in similar contexts by interchanging them. These types of words are grouped into synsets which are unordered sets. Where synsets are linked together if they are having even small conceptual relations. The usage of Lexican synonyms improves the users experience and allows a more accurate search result. It also improves the search time by tokenizing the information gathered by the collectors
