![]() The “Related search topics” visualisation shows a list of the top related topics per country, aggregated over the period of 2010 until the most recently updated month identified at the bottom of the visualisation. Related search topics by country and region over time Topics with indexed values below 1 are not provided by Google Trends, as they are not considered relevant. This is related to the way Google Trends indexes interest in a topic, normalising all searches on all topics in the given time period and country from 0 to 100. The visualisation includes data from 2010 until the month identified in the ‘as of’ date at the bottom of the visualisation.Ĭertain countries may have less than 10 top related topics in a given year. Topics are ranked from one to ten by their indexed popularity in a given country per year. The visualisation presents the top topics related to six key search topics: artificial intelligence, machine learning, natural language processing, computer vision, robotics, and automation. The “Top ten search topics” visualisation displays the evolution of the top ten related topics for a given country by year. Top ten search topics by country over time These may be new topics with few (if any) prior searches. In turn, some rising topics present very high percentage growths. For this reason, some countries may not have a rising topic for certain years. Google only provides trending or rising topics that have achieved ‘significant growth’ – defined as a search frequency increase of or above 50% – throughout the time period. represented by the coloured dots on the map) shows this percentage increase. They have experienced the most significant growth in search frequency over the selected time period. Hovering over each trending topic (i.e.They have been commonly searched for with the selected key search topic and.In sum, these ‘trending searches’ or rising topics fulfil two conditions: The visualisation includes data from 2010 until the month identified in the ‘as of’ date at the bottom of the visualisation. For each key search topic and country, the interactive map highlights the related topic that experienced the most significant growth in frequency during a given year. The “Top trending searches” visualisation presents the top rising topics related to each of the six key AI-related search topics: artificial intelligence, machine learning, natural language processing, computer vision, robotics and automation. Top trending searches by country and region over time The filter – based on cosine similarity – uses a threshold of 0.15 to systematically exclude the least related topics to the original search topic. Semantic similarity is applied to filter out topics that are least related to the original key search topic. ‘Adobe Illustrator’ for ‘AI’ and ‘Neuro-Linguistic Programming’ for ‘NLP’). For example, this included topics like ‘Artificial’, ‘Intelligence’, ‘Machine’ and ‘Learning’, as well as topics spuriously related to acronyms (e.g. Data Processingĭata cleaning involved the removal of repetitive or irrelevant related topics. Three visualisations have been constructed on OECD.AI using Google Trends data: “Top trending searches”, “Top ten search topics” and “AI-related search topics”. Caution is advised when comparing values between countries, as the overall search volume varies by country. ![]() The data displayed on OECD.AI is limited to OECD and G20 countries. AI-related developments gained significant momentum and popularity only after 2010). However, only data from 2010 onwards is displayed on OECD.AI to increase the relevance of the results (e.g. Google Trends provides data from 2004 onwards. Rising topics: A list of related ‘rising topics’ with the biggest increase in search frequency over a specified time period.Top topics: A list of the most popular topics – or ‘top topics’ – that are most often searched for in association with the search topic, based on correlational analysis.artificial intelligence, machine learning, etc.), the Google API provides two types of related topics: Topics are predefined thematic headings that group together alternative spellings, names in other languages, and words related to the same concept under a single label.įor any given search topic (e.g. To capture trends across various languages, the OECD.AI visualisations are based on topics provided by google trends. As such, Google Trends data measures public interest in a topic and the evolution of that interest across time, languages, and geographies. Google Trends provides access to a largely unfiltered sample of search queries made to Google, anonymised, categorised (according to the topic of the search query) and aggregated. ![]()
