Grammar Structure Delimiters
Key word searches use simple Boolean statements to determine whether an email contains sets of words that often appear together in spam, such as "toll" and "free." However, many emails may contain suspect sets of words without being spam, such as:
I traveled across the toll bridge today on my way to work. The change machine was broken so I received a free pass on the bridge.
Location also plays an important role in determining accuracy. For instance, the word "confidential", or a number of its equivalences like "classified" and "secret" if appearing multiple times scattered throughout an email or attachment does not necessarily mean that the email is confidential, however if these concepts were located in the header, footer, title page, or summary information of a document, then they would definitely imply that the message was of a confidential nature.
Concept Manager reduces the number of false positives and increases the accuracy by searching for concept patterns by grammar constructs (e.g. paragraph, sentence, line, bullet point, and centered text) and attachment layout (e.g. header, footer, summary information)
