    Pattern-based Aggregation of Named Entity Extractors

    Despite significant advances in named entity extraction technologies, state-of-the-art extraction tools achieve insufficient accuracy rates for practical use in many operational settings. However, they are not all prone to the same types of error, suggesting that substantial improvements may be achieved via appropriate combinations of existing tools, provided their behavior...

    Extensible Pre-Authentication in Kerberos

    Kerberos is a well-established authentication system. As new authentication methods arise, incorporating them into Kerberos is desirable. However, extending Kerberos poses challenges due to a lack of source code availability for some implementations and a lengthy standardization process. Kerberos allows a user to authenticate once and then connect to application...

    Is Openness Inflationary? Policy Commitment And Imperfect Competition

    This paper proposes a channel through which increased openness to international trade can increase a country's incentive to create inflation. The theoretical justification for this channel is the well known "Beggar thy neighbor" incentive, and its dominance relies on a monetary authority's ability to commit to policy as well as...

    Elaboration-time Synthesis of High-level Language Constructs in SystemC-based Microarchitectural Simulators

    Structural modeling serves as an efficient method for creating detailed microarchitectural models of complex microprocessors. High-level language constructs such as templates and object polymorphism are used to achieve a high degree of code reuse, thereby reducing development time. However, these modeling frameworks are currently too slow to evaluate future design...

    Mapping Conceptual Models to Database Schemas

    The mapping of a conceptual-model instance to a database schema is fundamentally the same for all conceptual models. A conceptual-model instance describes the relationships and constraints among the various data items. Given the relationships and constraints, the mappings group data items together into flat relational schemas for relational databases and...

    Partitioning and Synthesis for Hybrid Architecture Simulators

    Pure software simulators are too slow to simulate modern complex computer architectures and systems. Hybrid software/hardware simulators have been proposed to accelerate architecture simulation. However, the design of the hardware portions and hardware/software interface of the simulator is time-consuming, making it difficult to modify and improve these simulators. The authors...
