  • We introduce a novel Bayesian approach for deciphering complex substitution ciphers. Our method uses a decipherment model which combines information from letter n-gram language models as well as word dictionaries. Bayesian inference is performed on our model using an efficient sampling technique. We evaluate the quality of the Bayesian decipherment output on simple and homophonic letter substitution ciphers and show that unlike a previous approach, our method consistently produces almost 100% accurate decipherments. ...

  • At the other extreme, each disk controller now has tens of mega- bytes of storage and a very capable processor. It is quite feasible to have intelligent disks that offer either database access (SQL or some other non-procedural language) and even web service ac- cess. Moving from a block-oriented disk interface to a file inter- face, and then to a set or service interface has been the goal of database machine advocates...

  • The turn of the millennium has been described as the dawn of a new scientific revolution, which will have as great an impact on society as the industrial and computer revolutions before. This revolution was heralded by a large-scale DNA sequencing effort in July 1995, when the entire 1.8 million base pairs of the genome of the bacterium Haemophilus influenzae was published – the first of a free-living organism. Since then, the amount of DNA sequence data in publicly accessible data bases has been growing exponentially, including a working draft of the complete 3.

  • This paper examines how a new class of nonparametric Bayesian models can be effectively applied to an open-domain event coreference task. Designed with the purpose of clustering complex linguistic objects, these models consider a potentially infinite number of features and categorical outcomes. The evaluation performed for solving both within- and cross-document event coreference shows significant improvements of the models when compared against two baselines for this task.
