![]() Research by McKinsey has found that companies that make data accessible to their entire workforce are 40 times more likely to say analytics has a positive impact on revenue.Īrtificial intelligence (AI) is perhaps the one technology trend that will have the biggest impact on how we live, work and do business in the future. I don't think any of the aforementioned techniques would be useful, since the data points seem to always be big numbers, but I am open to ideas.Some great examples of data democracy in practice include lawyers using natural language processing (NLP) tools to scan pages of documents of case law, or retail sales assistants using hand terminals that can access customer purchase history in real time and recommend products to up-sell and cross-sell. There simply is too little data and for this term and even multiple days of scraping returns single spikes usually have a high value (80-100) and tend to overlap. Very weak terms that can not be salvaged.Would a better approach here be to take the average or the median, also should the samples that produce 0 be considered when calculating those metrics? In theory if a certain data point has appeared as 0 many times, does that mean the data for that week is scarcer than for other weeks where it might be 0 less frequently? I can't prove it, but I feel like any non-zero data should be included in the combined dataframe, rather than lost with the median and average metrics (median of will be 0 and the average would be 1.) Perhaps it will be interesting to experiment with average/median values and see how they perform (see next point).Īs we can see, despite looking funny with many data points at 50 and 100, the product is quite decent and some of the resulting data sets perform better than a random sample. If fact this worsens the quality of the data for the purposes it is needed. Here there is no point of doing this, since each data set is robust and has a value for each day. ![]() ![]() ![]() Popular terms where the data is consistent.The left graph is simply a plot of all the data sets and the right is the results of the rudimental combination I did. I have identified three different categories of search terms as detailed below. I have done a quick test with the most rudimental way of combining the data sets possible: just picking the maximum value for each week from the available data sets - we want to avoid 0s, anything is better than a 0. This is not an issue for western countries, but I am trying to conduct research based on search frequency in developing countries and here the lack of data makes some of the search samples very small and the data very scarce (sometimes as small as 0-2 data points for a period of 18 months).Īs other ways to acquire Trends data from Google have failed, I have resorted to scraping data daily to investigate whether it can be combined in a way that would create the most representative sample possible (the closest to the raw data we don't have). As you might know, Google Trends works by normalising a random sample of the search term data, with the sample changing at least once per day, from my experience. ![]()
