The Evolution of Search Engines
Search engines have been an integral part of our lives, helping us access information, find directions, shop online, and settle sandwich arguments. The concept of search engines has existed for centuries, with libraries acting as the earliest form of non-AI search engines. Librarians organized books and newspapers on shelves, creating systems to help people find the information they needed.
In the digital age, web search engines have replaced physical libraries. They scour the vast expanse of the World Wide Web, searching for relevant data. Instead of consulting a human librarian, we now rely on AI-powered search engines to find answers.
How Search Engines Work
To gather data from the web, search engines use a computer program called a web crawler. This program systematically finds and downloads web pages to create a massive repository of data. Once the data is collected, the AI system organizes it by building an index, commonly known as an inverted index. This index lists all the web pages that contain specific words, making it easier to retrieve relevant results.
When you enter a query into a search engine, the AI system utilizes the inverted index to find web pages that match the search terms. However, search engines don’t stop there. They also employ ranking algorithms to ensure that the most relevant results appear at the top of the list.
Better Understanding Through User Behavior
Search engines continuously strive to improve their results by learning from user behavior. When we use a search engine, our actions provide valuable training data for the AI system. For example, if a search result doesn’t answer our question, we bounce back to the search results and try another link. This bounce indicates a bad result. On the other hand, when we click on a web page and spend time reading it, that signifies a good result.
By analyzing user behavior like bounces and click-throughs, search engines gather the necessary data to refine their ranking algorithms. Our interactions with search results shape the AI system’s understanding of what answers our questions effectively.
Beyond Web Search: Knowledge Bases
While traditional search engines focus on providing web page results, there are instances where we want direct answers rather than links. In such cases, AI systems rely on knowledge bases. These databases encode information about the world as relationships between objects.
AI researcher Tom Mitchell and his team at Carnegie Mellon University created a massive knowledge base called the Never Ending Language Learner (NELL). NELL extracts facts from web pages and builds its knowledge base using repetition and multiple sources. AI systems like Siri can access this knowledge base to directly answer queries posed by users.
Conclusion
AI-powered search engines have revolutionized the way we access information. These systems gather vast amounts of data, organize it into indices, and utilize ranking algorithms to provide us with accurate and relevant results. By learning from user behavior and leveraging knowledge bases, search engines continuously improve their ability to understand and answer our questions.
