Predict a label for each event in the table using the model that was created by the createModelFromText operator, which learns how to predict labels from a text.

For example, consider a table with two columns: list of all cities in a country (comma-separated string) be first column and country name. The task is to train a model that can identify country name from a list of cities. The list of cities in the prediction can be incomplete compared to the training list. For instance, adding "Cleveland, London, Paris, Venice" would predict "USA" because cities with all four of the names are found in the USA in addition to other countries.

Cleveland, London => USA, England
Paris => France, USA(CA)
Venice => Italy, USA(FL)

Usage Details

LQL Command

predictLabelFromText(table, outputModelName, listOfColumns)

Input

table: Input table to train a model.
outputModelName: Model name that was created using the createModelFromText operator. Trained models are not displayed in the UI, so remember the name of the model that was created. If a model with the same name exists, this operation overwrites it without notification.
listOfColumns: List of columns to use for prediction. The order must be the same as listOfColumns during the training step.

Output

Input table plus an additional column: lhub_predicted_label.

Example

Input
table = github_logs

id	title	description
1	a, b	h, i
1	a, x	u, v

LQL: "lettersToUser" is model name that was created from the example section of create model from text .

LQL command

predictLabelFromText(table,"scoreEmail", "title", "description")

Output

id	title	description	lhub_predicted_label
1	a, b	h, i	spam
1	a, x	u, v	ham
