Abstract: A device configured to receive a sentence that includes a plurality of words. The device is further configured to input the words into a machine learning model that is configured to output a first feature vector based on the words. The device is further configured to identify a keyword within the sentence and to determine that the keyword is an implicit reference to an item. The device is further configured to identify a second feature vector in a reference list that closest matches a numeric value of the first feature vector and to identify an explicit reference in the reference list that is associated with the second feature vector. The device is further configured to replace the keyword with the explicit reference in the sentence and to output the sentence that includes the first explicit reference.

Abstract: A system for determining search results for a search string based on detecting an intent from the search string receives the search string. The system determines the intent of the search string by extracting a first set of features from the search string. The first set of features represent the intent. The system compares the first set of features with a second set of features labeled with an intent tag stored in a training dataset. The system determines whether the first set of features corresponds to the second set of features. In response to determining that the first set of features corresponds to the second set of features, the system determines that the first intent tag corresponds to the intent of the search string. The system produces a search result for the search string, where a first item in the search result is a text associated with the intent tag.
