Other search LF builders

This page describes the set of other search based LF builders that are available for classification and information extraction applications.

Timestamp builder (time series LF)

Label data points that fall within the specified periodic time intervals (start and end are both inclusive). The ranges (excluding years) are cyclic, meaning that, for example, specifying a start day of Saturday and an end day of Tuesday will select all Saturdays, Sundays, Mondays, and Tuesdays that satisfy the other constraints.

IP address builder (network LF)

Label data points based on whether an IP address in the specified field is a subnet of the specified IP network, represented by an IP address with a prefix (e.g., 10.0.0.0/30). Both IPv4 and IPv6 are supported.

SQL query builder (table based LF)

Label data points using a SQL query to return relevant rows of the dataset to mark them as having a label. This can be helpful or engineers and data anaylsts whose workflows have provided them with commonly used queries to find the segment of the data they care about.
