This paper describes the experiences of the OGSA-DAI team in profiling and benchmarking components of the OGSA-DAI database access middleware built using the Open Grid Services Infrastructure and the emerging Database Access and Integration Services Global Grid Forum recommendations. The profiling approach and the tools used are described. A number of areas of concern are then analysed in detai...

We introduce a new paradigm for outsourcing the durability property of a multi-client transactional database to an untrusted service provider. Specifically, we enable untrusted service providers to support transaction serialization, backup and recovery for clients, with full data confidentiality and correctness. Moreover, providers learn nothing about transactions (except their size and timing)...

In this paper we present our work on creating a database of emoticons – face marks widely used to convey emotions in text-based online communication. The database is created by gathering emoticons from numerous dictionaries of face marks and online jargon. The inconsistencies in emotion classification provided by various dictionaries are solved by processing them with an affect analysis system ...

Ode is a database system and environment based on the object paradigm. The database is defined, queried and manipulated using the database programming language O++, which is based on C++. The O++ compiler translates O++ programs into C++ programs which contain calls to the Ode object manager. The current O++ implementation provides facilities for creating and manipulating persistent objects, an...

The National Bridge Inventory (NBI) database provides detailed bridge information with full coverage in the United States. In the database, each bridge record has an associated geographic location, which makes it possible to match the NBI records with road vectors in a geospatial database. This paper presents our approach to conflating the NBI database with U.S. Census Bureau's Topologically In...

In this paper, we describe the designing, recording and checking procedures of a multi-accented Mandarin speech database, and present benchmark evaluation of this database. The database was recorded in 6 cities in China, containing 1200 speakers’ accented Mandarin speech of continuous digits, isolated words and sentences. In total, 520k utterances (572.5 hours) were collected. We perfrom the in...

In this paper, we demonstrate a statistical approach for creating a 3D face from photographs by exploiting the face information gained from faces scanned into a large 3D face database. We also estimate facial expressions using this database, creating speech-related deformations used for talking head animation for auditoryvisual speech research. The database has 9 different face postures from ov...
