Abstract: According to an embodiment, the present application provides a method for marketing campaigns utilizing a tokenization framework, which relies on smart contracts for its operations. This method starts by accepting a campaign budget, which is for initiating the setup of a smart contract associated with this budget. The smart contract is responsible for the conversion of this budget into tokens, which are earmarked for distribution to users who enroll in the campaign. Operations of the smart contract include the periodic identification and verification of user-generated content relevant to the campaign. This is achieved by examining specific reference tags linked to the content. The smart contract evaluates the effectiveness of the content by analyzing engagement metrics, such as the number of views, likes, and comments. Based on these metrics, the smart contract calculates the appropriate token rewards for each participant.

Then the content request is forwarded down the hierarchy until, along a published linear chain corresponding to the character string, until a content source is reached. Content is provided to the requestor along a reverse path of the content request.

Abstract: Systems for automatic speech recognition and/or natural language understanding automatically learn new words by finding subsequences of phonemes that, if they were a new word, would enable a successful tokenization of a phoneme sequence. Systems can learn alternate pronunciations of words by finding phoneme sequences with a small edit distance to existing pronunciations. Systems can learn the part of speech of words by finding part-of-speech variations that would enable parses by syntactic grammars. Systems can learn what types of entities a word describes by finding sentences that could be parsed by a semantic grammar but for the words not being on an entity list.

Abstract: A technique serves information items associated with at least two item-serving modes using shared resources. For example, the technique delivers dynamic search ads in a dynamic search ad (DSA) mode using processing resources that were originally developed for serving text ads in a text ad (TA) mode.

In a second aspect, the technique performs further processing based on output results generated by the TA-mode processing flow, with the objective of identifying a set of landing pages associated with the query. Overall, the technique reduces the consumption of resources in the serving of ads, and simplifies the maintenance of an ad-serving system. The technique also allows one mode to use algorithmic advances developed for use in another mode.
