Use the form below to search the database of articles to create a crosstab. The resulting crosstab shows the number of articles within each category selected by the news sources selected in the form below. Start and end dates can be specified, otherwise the entire history of articles is searched. Similarly, a certain minimum probability (between 0 and 1) can be specified that the selected categories must meet, otherwise all articles are returned for the selected categories regardless of the probability of their belonging to that category. This search is conducted only on relevancy based on the trained model; user designated categories are not considered.
