Abstract: A method of predicting a release date of an item is provided. The method includes applying a first rule set to a first data set to create a second data set. The first rule set includes a rule that correlates a phrase with a date within a text string of the first data set. A second rule set is then applied to the second data set to create a third data set. The second rule set can include a rule that identifies a first item within a text string of the second data set and correlates the first item with the date such that the third data set has the first item that correlates with the date. A release date is then identified for the first item based on the date and a language pattern associated with the date.

Abstract: A search query and a concept comprising a feature are received from a user. Positive and negative item sets are identified, where items of the positive item set comprise the feature and items of the negative item set do not comprise the feature. A hyperplane located between the positive and negative item sets is generated using a machine learning model. A concept activation vector (CAV) orthogonal to the hyperplane is determined. The CAV is used to produce a modified search query vector. Based on comparing the modified search query vector with item vectors, a second set of search results is provided.
