A system for augmenting click-through data with latent information present in the click-through data for use in generating search results that are better tailored to the information needs of a user submitting a query is provided. The augmentation system creates a three-dimensional matrix with the dimensions of users, queries, and documents. The augmentation system then performs a three-order singular value decomposition of the three-dimensional matrix to generate a three-dimensional core singular value matrix and a left singular matrix for each dimension. The augmentation system finally multiplies the three-dimensional core singular value matrix by the left singular matrices to generate an augmented three-dimensional matrix that explicitly contains the information that was latent in the un-augmented three-dimensional matrix.

GridBatch provides an infrastructure framework that hides the complexities and burdens of developing logic and programming application that implement detail parallelized computations from programmers. A programmer may use GridBatch to implement parallelized computational operations that minimize network bandwidth requirements, and efficiently partition and coordinate computational processing in a multiprocessor configuration. GridBatch provides an effective and lightweight approach to rapidly build parallelized applications using economically viable multiprocessor configurations that achieve the highest performance results.

Various embodiments of a system and associated method for anonymization of text without losing semantic utility of text by extracting a latent embedding representation of content with respect to a given task and by learning an optimal strategy for text embedding manipulation to satisfy both privacy and utility requirements are disclosed herein. In particular, the system balances private attribute obfuscation with retained semantic utility.

Various embodiments for systems and methods of tracking disaster footprints using social streaming media using nonnegative matrix factorization are disclosed herein. The system extracts a summarization output from historical data and compares the summarization output with incoming data to identify differing or similar topics within the data. The summarization output is projected to adjust a time-dependency of the summarization output to enable a more direct comparison. The system additionally uses the summarization output to encode topic data within historical data to reduce computational overhead.

Provided is a sludge drying composite conditioner. The sludge drying composite conditioner comprises a Fenton's reagent or/and Fenton-like reagent and a matrix construct, the weight ratio between the Fenton's reagent or/and the Fenton-like reagent and the matrix construct is 1:0.05 to 300, and the matrix construct is powder. Further provided is an application method of the sludge drying composite conditioner, which comprises the steps of: adding a Fenton's reagent or/and Fenton-like reagent in a sludge, performing stirring and mixing, and performing an oxidation reaction; and adding a matrix construct to the sludge added with the Fenton's reagent or/and Fenton-like reagent and performing stirring and mixing. For the sludge drying composite conditioner, through the coordinated effect of the Fenton's reagent or/and Fenton-like reagent and the powder matrix construct, the extracellular polymeric substances in the sludge are effectively damaged, the compressibility of organic matter is reduced, and the drying performance of sludge is improved. The application method thereof has a simple working process and easily controllable conditions and reduces the drying time for sludge, thereby achieving large-scale treatment of sludge.

As a result of the systems and methods described herein, an alternative MapReduce implementation is provided which monitors for impending termination notices, and allows dynamic checkpointing and storing of processed portions of a map task, such that any processing which is interrupted by large scale terminations of a plurality of computing devices—such as those resulting from spot market rate fluctuations—is preserved.
