With more and more speech corpora at hand the unit selection technique is a promising approach in concatenative speech synthesis. What is missing are models of optimal parameters that sufficiently describe utterances to be produced and their corresponding counterparts in collections of speech data. Prior to this, existing corpora have to be annotated on possibly relevant linguistic and signal l...

In this brief paper, I present the a simple straight forward formal language for describing access control based on the CORBA Security Credentials model. This language serves as a formal description of the access control mechanism. I also show how the language can be extended to describe the CORBA Security access control model that uses the notion of required rights, which is more complex, yet ...

38 AI MAGAZINE Today’s enterprises need to make decisions based on analyzing massive and heterogeneous data sources. More and more aspects of business are driven by data, and as a result more and more business users need access to data. Offering easy access to the right data to diverse business users is of growing importance. There are several challenges that must be overcome to meet this goal....

Sensor data have broadened their scope recently, ranging now from the simple time series measurements to, e.g., hyperspectral satellite image maps timeseries. In addition to observed data, simulation data increasingly have to be merged, for example 4-D ocean and atmospheric data. The majority of these data fall into the category of multi-dimensional rasters. However, when it comes to flexible r...

The anusaaraka system (a kind of machine translation system ) makes text in one Indian language accessible through another Indian language. The machine presents an image of the source text in a language close to the target language. In the image, some constructions of the source language (which do not have equivalents in the target language) spill over to the output. Some special notation is al...

This paper presents a cross-language retrieval system which integrates shallow parsing and lexical semantic databases in an interactive approach to information access. At indexing time, the system extracts a list of phrases for every language in the collection. At search time, the system bridges the gap between the user's query and the relevant phrases in the collection in any language, expandi...

We address the problem of privacy-preserving access control in distributed systems. Users commonly reveal more personal data than strictly necessary to be granted access to online resources, even though existing technologies, such as anonymous credential systems, offer functionalities that would allow for privacy-friendly authorization. An important reason for this lack of technology adoption i...

In this paper, we present Coral, an interface in which complex corpus queries can be expressed in a controlled subset of natural English. With the help of a predictive editor, users can compose queries and submit them to the Coral system, which then automatically translates them into formal AQL statements. We give an overview of the controlled natural language developed for Coral and describes ...

The reuseability and accessibility of lexical and linguistic resources often requires substantial programming overhead and detailed knowledge of the structure and nature of resource-specific information. Each resource has its own representation syntax and covers a particular subset of linguistic phenomena. This paper will discuss ways to overcome these barriers to resource reuse and presents a ...

Interfaces for mobile information access need to allow users flexibility in their choice of modes and interaction style in accordance with their preferences, the task at hand, and their physical and social environment. This paper describes the approach to multimodal language processing in MATCH (Multimodal Access To City Help), a mobile multimodal speech-pen interface to restaurant and subway i...
