Identify potential NLP contractors

[waldoj]

For this project, we need somebody able to turn a series of repeated definitions for the same terms:

{
    "person": [
        "any natural person, corporation, firm, association, organization, partnership, limited liability company, business or trust.",
        "one or more individuals, partnerships, associations, societies, trusts, organizations, or corporations;",
        "any individual, corporation, business or land trust, estate, trust, partnership, association, two or more persons having a joint or common interest, state agency, or any legal entity.",
        "a natural person, corporation, business trust, estate, trust, partnership, association, joint venture, government, governmental subdivision or agency, or any other legal or commercial entity."
    ],
    "real property": [
        "all lands, including improvements and fixtures thereon, and property of any nature appurtenant thereto, or used in connection therewith, and every estate, interest and right, legal or equitable, therein, including terms for years and liens by way of judgment, mortgage or otherwise and the indebtedness secured by such liens.",
        "any interest in land and may also include any appurtenances and improvements to the land.",
        "one or more defined interests, benefits or rights inherent in the ownership of real estate.",
        "the surface land, improvements thereto, and fixtures, and is synonymous with “realty” and “real estate.”",
        "land, buildings, fixtures, and all other improvements to land. The terms “land,” “real estate,” “realty,” and “real property” may be used interchangeably."
    ]   
}

into a list of likely synonyms, based on the provided definitions, including the strength of the correlation:

{
    "person": {
        "natural person": 1.0,
        "corporation": 0.98,
        "trust": 0.91,
        "entity": 0.86,
        "individual": 0.86,
        "business": 0.79
    },
    "real property": {
        "land": 1.0,
        "improvement": 1.0,
        "fixture": 0.97,
        "realty": 0.94,
        "real estate": 0.89
    }
}

The task is to identify the software and the processes necessary to accomplish this, using free, open source software.

Where do we find such vendors? How do we ensure that they see (and respond to) the RFP that we'll inevitably publish?
