We formalized and explored the notion of stateless computation. Our investigation of stateless computation focused on two important aspects: (1) guaranteeing and verifying self-stabilization of stateless computation systems and (2) analyzing the com…

Stateless Computation

We present and explore a model of stateless and self-stabilizing distributed computation, inspired by real-world applications such as routing on toda…

Computation and Language

We have shown that a statistically significant improvement in the performance of NER system for a given language can be obtained when the training data is supplemented with word clusters from a secondary language(s) which is written using the same a…

"Translation can't change a name": Using Multilingual Data for Named …

Named Entities (NEs) are often written with no orthographic changes across different languages that share a common alphabet. We show that this can be…
