Abstract: The disclosed embodiments illustrate methods and systems for data processing to predict domain knowledge of a user for content recommendation. The method includes extracting a set of features from user data based on at least a domain-of-interest. The method further includes categorizing each feature in each set of the extracted set of features into one of a plurality of categories. The method further includes determining a domain literacy weight of the user for each category of the plurality of categories based on at least an average weight associated with each set of the extracted set of features in each category. The method further includes predicting the domain knowledge of the user based on at least the determined domain literacy weight associated with each category. The predicted domain knowledge is further utilized for the content recommendation to the user.

Abstract: Methods and systems for providing secure recording of revisions made to electronic documents, using secure methods to validate the recorded changes, are disclosed. An electronic device making a change to an electronic document can transmit the change to the network. An audit log chain is residing on the network and shared among all the nodes on the network. A node on the network can verify a change of document made by other nodes and add a new block to the chain using one-way hashes, making the chain resistant to tampering. If an invalid block is detected, the system can send an auditing alert to the network. The audit log can be strongly resistant to tampering, providing reliable evidence for use in audit compliance, investigations, and business or court record keeping.

Abstract: The disclosed embodiments illustrate methods and systems for determining strategies in crowdsourcing. The method includes generating first graphs representative of an association between workers, between crowdsourcing tasks, or between workers and crowdsourcing tasks, at first time instance. The method includes determining values of metrics associated with first graphs, comparing determined values of metrics and threshold values of metrics, and generating second graphs based on comparison. The second graphs are representative of an association between workers, between crowdsourcing tasks, or between workers and crowdsourcing tasks, at second time instance. The second time instance precedes first time instance. Thereafter, the method includes determining strategies based on second graphs. The strategies comprise recommendation to a first set of workers for attempting a first set of crowdsourcing tasks or recommendation to first set of workers for increasing interaction with second set of workers. The method is performed by one or more microprocessors.
