We introduce the notion of persistent authenticated dictionaries, that is, dictionaries where the user can make queries of the type “was element e in set S at time t?” and get authenticated answers. Applications include credential and certificate validation checking in the past (as in digital signatures for electronic contracts), digital receipts, and electronic tickets. We present two data str...

In this paper, which is the sequel to [GN04a], we study inverse estimates of the Bernstein type for nonlinear approximation with structured redundant dictionaries in a Banach space. The main results are for blockwise incoherent dictionaries in Hilbert spaces, which generalize the notion of joint block-diagonal mutually incoherent bases introduced by Donoho and Huo. The Bernstein inequality obta...

The exceedingly large size of fault dictionaries constitutes a fundamental obstacle to their usage. We outline a new method to reduce significantly the size of fault dictionaries. The proposed method partitions the test set and a combined signature is stored for each partition. The new approach aims to provide high diagnostic resolution with a small number of combined signatures. The experiment...

This paper aims to compare the efficiency of print and electronic Learners’ dictionary in helping learners of English as a Second Language (ESL) discriminate closely related senses of words in dictionaries. Issues relating to the development of test instruments for capturing this efficiency are discussed. This includes matters pertaining to the selection of research and resource dictionaries, f...

The customization of Machine Translation systems concentrates, for the most part, on MT dictionaries. In this paper, we focus on the customization of complex lexical entries that involve various types of lexical collocations, such as sub-categorization frames. We describe methods and tools that leverage existing parsers and other MT dictionaries for customization of MT dictionaries. This custom...

We, machine translation providers, as members of Asia-Pacific Association for Machine Translation (AAMT), are now establishing environments for sharing and exchanging user dictionaries among different machine translation systems. In order for users to utilize machine translation systems more effectively, we define common formats of user dictionaries, and establish electronic environments availa...

Visual Elements in Translative Dictionaries Aimed at the Foundation Phase against Background of Literacy Development. used for teaching and learning an educational setting undoubtedly have purpose function (if a dictionary is understood according to lexicographic theory functions), whereby such concerned with active development literacy skills. In case dictionaries foundation phase, target user...
