Systems and methods for classifying data in building automation systems

A building automation system (BAS) comprising:

• a plurality of BAS devices comprising sensors and building equipment configured to monitor and control one or more building spaces, wherein each of the BAS devices is associated with one or more unclassified data points, each of the unclassified data points comprising an attribute containing a substring;
• and
• a processing circuit configured to generate a set of probability values for each unclassified data point, each of the probability values corresponding to a different BAS point type and indicating a probability that the unclassified data point belongs to the corresponding BAS point type based on the substring contained in the attribute of the unclassified data point;
• wherein the processing circuit is configured to assign a BAS point type to each of the unclassified data points by identifying the BAS point type corresponding to a greatest probability value in each set of probability values.

• and
• a processing circuit configured to identify a set of classified data points having known BAS point types, the processing circuit comprising:
• a memory device storing a list of the known BAS point types and a term set comprising a plurality of substrings contained in attributes of the classified data points;
• a learner configured to determine, for each combination of a substring selected from the plurality of substrings in the term set and a BAS point type selected from the list of known BAS point types, a probability that each unclassified data point belongs to the selected BAS point type if the attribute of the unclassified data point contains the selected substring;
• and
• a classifier configured to assign a BAS point type to each of the unclassified data points by identifying the combination of the selected substring and the selected BAS point type with a greatest probability.

A building automation system (BAS) comprising:

• a plurality of BAS devices comprising sensors and building equipment configured to monitor and control one or more building spaces, wherein each of the BAS devices is associated with one or more unclassified data points, each of the unclassified data points having a plurality of attributes comprising a first attribute containing a substring and a second attribute containing a numeric value;
• and
• a processing circuit comprising:
• a memory device storing a list of substrings and a list of BAS point types;
• and
• a classifier configured to filter at least one of the list of substrings and the list of BAS point types based on the plurality of attributes of the unclassified data points;
• wherein the classifier is configured to assign one of the BAS point types to each unclassified data point based on the substring contained in the first attribute of the unclassified data point and the numeric value contained in the second attribute of the unclassified data point.
