System and method for email signature extraction from unstructured text

1. A process for extracting structured contact data from a signature block in an unstructured text or email, said process comprising:

(a) receiving an unstructured text or email from a data source;

(b) determining a position of a signature block candidate within said unstructured text or email;

(c) validating patterns and sentence bounds and/or parts of speech detection in said signature block candidate, thereby determining that said signature block candidate comprises a valid signature line and is a detected signature block;

(d) using a named entity recognition model with a pattern matcher to detect from said detected signature block a business name candidate and address line;

(e) using an attribute parser to extract attributes of standard formats from at least one selected from the group consisting of: phone number, URL, email address and social media handle, thus yielding extracted attributes;

(f) sending said extracted attributes to a structured contact profile data file;

(g) using a fuzzy match organization name model to determine if said business name candidate is either an exact or close match to a pre-existing organization name database set;

(h) assigning an attribute confidence score to said business name candidate;

(i) sending said attribute confidence score to said structured contact data file;

(j) extracting structured street, city, state and/or zip code from said address line; and

(k) sending said extracted structure street, city, state and/or zip code to said structured contact data file.

2. A system for extracting structured contact data from a signature block in an unstructured text or email, said system comprising:

a device that collects a signature block in an unstructured text or email and transmits said unstructured text or email;

a first event-driven computing cloud service that routes (1) synchronous inputs of said unstructured text or email, and/or (2) asynchronous batch inputs of said unstructured text or email, wherein said asynchronous batch inputs are stored in a queue;

a Hadoop cluster device that (a) receives said synchronous inputs directly from said first event-driven computing cloud service, and/or (b) pulls said asynchronous batch inputs from said queue, wherein said Hadoop cluster device includes a natural language processor that processes said unstructured text or email from said synchronous and/or asynchronous inputs so as to (c) extract contact data, and (d) scores said contact data; and

a second event-driven computing cloud service that receives said extracted contact data and combines said scores from said Hadoop cluster device, thereby forming structured contact data.

3. The system according to claim 2 , wherein said second event driven computing cloud returns said structured contact data to said Hadoop cluster device.

4. The system according to claim 2 , wherein said second event-driven computing cloud service performs at least one task selected from the group consisting of: attribute regex parsing, lookup validation, name string parsing, and combinations thereof.

5. The system according to claim 4 , wherein said second event-driven computing cloud service uses a result from said task to validate an attribute candidate against a regex or small set of filters, or to resolve single string names into multiple fields, thereby generating first and last name attributes.

6. The system according to claim 5 , wherein said second event-driven computing cloud service validates said first and last name attributes from a name string against person name reference sets.

7. The system according to claim 5 , further comprising a third event-driven computing cloud service,

wherein said second event-driven computing cloud service combines results from previous processing steps to generate said structured contact data, and passes said structured contact data to said third event-driven computing cloud service, and

wherein said third event-driven computing cloud service stores the structured contact data in a file.
