| CaptureClassifier | The CaptureClassifier is used for text extraction. It locates the variable in the text and extracts it. | Classifier Settings |
| Chart | We use a chart to denote a data point (e.g., a text note, a patient chart) | |
| Dictionary | A dictionary is a list of words that can be used with rules. | Dictionaries |
| Dictionary tag | The dictionary tag is used in the basic view to indicate a dictionary. | Basic View |
| ID | The ID is used to identify each chart. | |
| Keyword tag | The keyword tag is used in the basic view when building rules. | Basic View |
| Or tag | The Or tag is used in the basic view when building rules. | Basic View |
| Predicted label | The predicted label is the label that is generated by CHARTextract. The predicted label will be the one with the highest score. If all labels have a score of 0, then the Negative label will be assigned to the chart. | |
| Primary rule | A primary rule consists of a pattern-matching rule and an associated score. Primary rules may have secondary rules. | Rules Types and Modifiers |
| RegexClassifier | The RegexClassifier is used for classifying charts into different labels. The RegexClassifier uses a series of rules to determine the most appropriate label for a chart. | Classifier Settings |
| Regular expression | A regular expression is a sequence of symbols and characters expressing pattern to be searched for within a longer piece of text. CHARTextract relies on regular expressions to build its rules. | Regular Expressions Primer |
| Rule | A rule consists of a regular-expression-based pattern and an associated score. | Rules |
| Rule modifier | Secondary rules can have an associated rule modifier which specify if the rule type should restrict its search to Before or After the primary rule match. | Rule Types and Modifiers |
| Rule refinement | Rule refinement is an interative process in which rules are modified so that CHARTextract’s prediction match the ground truth labels. | Rule refinement |
| Rule type | Secondary rules have an associated rule type which specify how the secondary rule interacts with the primary rule. | Rule Types and Modifiers |
| Secondary rule | Secondary rules consist of a regular-expression-based rule, a score, and a rule type. Secondary rules are always attached to a primary rule. | Rule Types and Modifiers |
| Tag | Tags are used by the basic view. | Using the Basic View |
