1. A system configured to facilitate associating semantic labels with content, the system comprising: one or more processors configured to execute computer program modules, the computer program modules comprising: a document module configured to obtain matched sets of documents, wherein individual matched sets of documents include a structured document and an unstructured document having related content; a fact module configured to identify numeric instances present in the documents obtained by the document module such that, responsive to the document module obtaining a first matched set of documents including a first structured document and a first unstructured document, the fact module identifies a first set of numeric instances present in the first structured document and a second set of numeric instances present in the first unstructured document; a correlation module configured to correlate numeric instances in different documents in a common matched set of documents that express matching numbers such that, responsive to the first set of numeric instances including a first numeric instance expressing a first number and the second set of numeric instances including a second numeric instance expressing the first number, the first numeric instance and the second numeric instance are correlated based on the common expression of the first number; a structured context module configured to determine, responsive to identification of the first set of numeric instances in the first structured document and to correlation of the first numeric instance with the second numeric instance, structured contextual information for the first numeric instance, such structured contextual information labeling the first numeric instance and/or content associated with the first numeric instance in the first structured document, such structured contextual information including one or more of a semantic label, a dimension, or an attribute of the first numeric instance and/or the content associated with the first numeric instance; a context association module configured to, responsive to correlation of the first numeric instance with the second numeric instance, associate the structured contextual information for the first numeric instance in the first structured document with content appearing with the second numeric instance in the first unstructured document wherein associating structured contextual information for the first numeric instance with content appearing with the second numeric instance includes associating textual content appearing with the second numeric instance with the information labeling the first numeric instance; and an analysis module configured to analyze associated structured contextual information for the first numeric instance and the content appearing with the second numeric instance to determine one or more trends in the associated contextual information, the analysis comprising a statistical analysis of content appearing with the second numeric instance associated with structured contextual information for the first numeric instance having one or more common features, the one or more common features comprising one or both of a common dimension and/or a common dimension type.
