In one embodiment, a method comprises receiving a request for a particular user identification (ID) to perform a particular operation on a particular data object. An entitlement cache associates each operation that the particular user ID is entitled to perform with a first encoding of a tuple of a plurality of tuples. An object mapping cache associates each tuple of the plurality of tuples with a second encoding of each tuple of the plurality of tuples. An object mapping is used to determine a first tuple. The object mapping cache is used to determine a first vector of one of more left values based on the first tuple. The entitlement cache is used to determine a second vector of one or more value pairs. In response to identifying a match between the first vector and the second vector, the particular user ID is granted access to the particular data object.

Efficient traversal of hierarchical datasets

A method for classifying a text fragment by applying one or more rule functions is provided. The method includes (i) obtaining a set of words from one or more sentences of the text fragment obtained from a multimedia content, (ii) mapping each word from the set of words with one or more category map tables to obtain a set of candidate vector, each candidate vector includes at least one category associated with each word, (iii) generating one or more category vectors based on the at least one category, (iv) applying rule functions on the one or more category vectors, (v) generating a candidate classification decision matrix based on the rule functions, and (vi) classifying the text fragment based on the candidate classification decision matrix. The candidate classification matrix includes results of each rule function applied on each of the category vector.
