wherein the one or more beacon terms comprises each corpus term in the corpus database having a feature vector satisfying a threshold distance from the one or more embeddings for the first set of context terms.

6. The method according to claim 5 , further comprising calculating, by the computer, a context score for each context term in the first set of context terms based upon at least one of: a word probability, a word co-occurrence count, and a word-to-word probabilistic implication, wherein the embedding of each context term of the first set of context terms is based upon the context score for the context term.

7. The method according to claim 6 , further comprising:

for each context term of the first set of context terms, setting, by the computer, the context score as a default score; and

adjusting, by the computer, the context score for at least one context term of the first set of context terms in accordance with one or more user inputs received from the client device via the user interface.

8. The method according to claim 1 , wherein the first set of context terms comprises at least one out-of-context term.

9. The method according to claim 1 , further comprising:

receiving, by the computer, from a bid server an availability list of one or more available webpages requesting bids from a bid system; and

calculating, by the computer, a real-time page score for each available webpage in the availability list based, at least in part, upon a number of occurrences of one or more campaign terms comprising the one or more updated beacon terms and one or more in-context terms in the available webpage.

10. The method according to claim 9 , further comprising identifying, by the computer, a bidding-list of webpages comprising each of the one or more available webpages of the availability list satisfying a bid threshold.

11. A system comprising:

a corpus database comprising non-transitory storage medium configured to a plurality of corpus terms; and

a server comprising a processor configured to:

prior to a future bid-time:

receive a first set of one or more context terms from a client device via a user interface;

select from the plurality of corpus terms stored in the corpus database one or more beacon terms using the first set of one or more context terms, each corpus term selected for the one or more beacon terms has a co-occurrence probability with one or more context terms of the first set of one or more context terms that satisfies a threshold probability;

present the one or more beacon terms selected using the first set of one or more context terms to a user via the user interface of the client device;

receive a second set of one or more context terms from the client device via the user interface for updating the first set of one or more context terms;

select one or more updated beacon terms from the plurality of corpus terms based upon one of the first set of one or more context terms or the second set of one or more context terms;

calculate a plurality of page scores for a plurality of corpus webpages stored in the corpus database, each page score for a corpus webpage calculated based upon an amount of occurrences of the one or more updated beacon terms, the first set of one or more context terms, or the second set of one or more context terms; and

generate, in a campaign database, campaign data of the user comprising the one or more updated beacon terms and one or more contextual webpages selected from the plurality of corpus webpages satisfying a threshold page score, the campaign data configured for identifying one or more placement webpages at the future bid-time.

12. The system according to claim 11 , wherein the server is further configured to store, into the campaign database, the campaign data, wherein the campaign data is configured for executing a real-time bidding selection operation for one or more available webpages during the real-time bidding selection operation.
