Understanding Semantic Search

Understanding Semantic Search

Semantic search is a data searching technique in which a search query aims to not only find keywords but to determine the intent and contextual meaning of the words a person is using for search.

It involves understanding the context in which keywords are used and analyzing the underlying intent behind the search query.

For example, if a user searches for “apple,” a semantic search engine will try to understand whether the user is looking for information about the fruit or the tech company.

Semantic search is not just about understanding the meaning of individual words, but also how those words relate to each other in a phrase or sentence.

It’s about understanding language the way humans do – with all its complexity, ambiguity, and nuance.


Google's Approach to Semantic Search

Google’s Approach to Semantic Search

Google’s approach to semantic search is a significant shift from traditional keyword-focused search methods.

Semantic search seeks to improve search accuracy by understanding the searcher’s intent and the contextual meaning of terms as they appear in the searchable dataspace.

This approach is designed to generate more relevant results.

Google’s semantic search is not just about understanding the meaning of specific words in a query, but also interpreting the intent behind those words based on the context.

This involves analyzing factors such as the location of the searcher, the time of the search, the device used, and the searcher’s personal search history.

In theory, semantic search should be able to return results that reflect a searcher’s intent, and in some cases improve Google’s ability to give an answer right away without referring users to other websites.

This is a significant advancement in the evolution of search technology, as it allows Google to provide more precise and personalized search results.

Google’s semantic search attempts to improve on the search formula intended to produce relevant search results for web users by creating rules that define a searcher’s intent and the contextual meaning of search terms.

This approach is part of Google’s ongoing efforts to understand the web’s content and deliver the most relevant and useful results to users.

BERT: Pre-training of Deep Bidirectional Transformers for Language Understanding

BERT: Pre-training of Deep Bidirectional Transformers for Language Understanding

The Bidirectional Encoder Representations from Transformers (BERT) model has revolutionized the field of language understanding and semantic search.

Developed by Jacob Devlin, Ming-Wei Chang, Kenton Lee, and Kristina Toutanova, BERT’s unique approach to language representation has set a new standard in the industry.

BERT is a deep learning model that pre-trains bidirectional representations from unlabeled text.

Unlike traditional models that train text from left to right or right to left, BERT conditions on both left and right context in all layers.

This bidirectional training gives BERT a more profound understanding of language context and flow than single-direction models.

BERT can be fine-tuned with just one additional output layer, making it versatile for a wide range of tasks, such as question answering and language inference, without substantial task-specific architecture modifications.

The Role of Transformers in the BERT Model

Transformers are a critical component of the BERT model.

They are responsible for understanding the context in the input data, a fundamental aspect of semantic search.

Transformers allow the model to focus on different words in the sentence and understand their context relative to other words.

The Concept of Bidirectional Training in the BERT Model

Bidirectional training is a key feature of the BERT model.

This approach allows the model to understand the context of a word in relation to all the other words in the sentence, rather than just the words that precede or follow it.

This results in a more comprehensive understanding of the text, enhancing the accuracy of semantic search and other natural language processing tasks.

Semantic Experiences: Experiments in Understanding Language

Semantic Experiences: Experiments in Understanding Language

Google’s Semantic Experiences is a project that aims to understand language through the use of machine learning.

The project uses billions of lines of dialogue to teach an AI how real human conversations flow.

Once the AI has learned from this data, it is then able to predict how likely one statement would follow another as a response.

In the Semantic Experiences project, there are two main applications.

The first one is ‘Verse by Verse’, where users are given the opportunity to compose poetry in collaboration with classic American poets like Walt Whitman, Emily Dickinson, Edgar Allen Poe, and many more.

The AI acts as a muse, making suggestions of verses as the user writes a poem.

The second application is ‘Semantris’, a word association game that uses the same technology.

Each time a player enters a clue, the AI looks at all the words in play and chooses the ones it thinks are most related.

These applications demonstrate the AI’s full capabilities and weaknesses, including how it can reflect human cognitive biases.

They are raw research demos that provide insights into the future of language understanding and semantic search.
