![]() ![]() ![]() Trivia: The former Kingdom of Swaziland changed its name to the Kingdom of Eswatini in 2018, to prevent confusion with Switzerland. gtab to the rescue!įortunately, this library solves these problems. Here, ts_timestamp is an array with dates, and, max_ratio is the calibrated value and max_ratio_(hi|lo) are error bounds related to our method. In the offline pre-processing phase, an "anchor bank" is constructed, a set of Google queries spanning the full spectrum More formally, the method proceeds in two phases: Gtab constructs a series of pre-computed queries,Īnd is able to calibrate any query by cleverly inspecting those. Of popularity, all calibrated against a common reference query by carefully chaining multiple Google Trends requests. Steps suffice (see empirical evaluation).Ī full description of the gtab method is available in the following paper: In the online deployment phase, any given search query is calibrated by performing an efficient binary search in the anchor bank.Įach search step requires one Google Trends request (via pytrends), but few Calibration of Google Trends Time Series. In Proceedings of the 29th ACM International Conference on Information and Knowledge Management (CIKM). Please cite this paper when using gtab in your own work.Ĭode and data for reproducing the results of the paper are available in the directory cikm2020_paper.įor a less technical explanation, see our 7-minute summary video. ![]() Want to use Python?

This is likely due to Google itself and not something in gtab. The workaround we have used is to employ proxies(IPv4 proxies, whitelisted through your IP address). These can be added to the conn_config parameter in a list in the set_options method (see here). ![]()
