This article proposes a new method for image separation into a linear combination of morphological components. Sparsity in global dictionaries is used to extract the cartoon and oscillating content of the image. Complicated texture patterns are extracted by learning adapted local dictionaries that sparsify patches in the image. These global and local sparsity priors together with the data fidel...

External-memory dictionaries are a fundamental data structure in file systems and databases. Versioned (or fullypersistent) dictionaries have an associated version tree where queries can be performed at any version, updates can be performed on leaf versions, and any version can be ‘cloned’ by adding a child. Various query/update tradeoffs are known for unversioned dictionaries, many of them wit...

The problem of extracting bilingual dictionaries from Wikipedia is well known and well researched. Given the structural and rich multilingual content of Wikipedia, a language independent approach is necessary for extracting dictionaries for various languages more so for under-resourced languages. In our attempt to mine dictionaries for under-resourced languages, we developed an iterative approa...

Compared with printed dictionaries, online dictionaries provide a number of unique possibilities for the presentation and processing of lexicographical information. However, in Müller-Spitzer/Koplenig/Töpel (2011) we show that – on average users tend to rate the special characteristics of online dictionaries (e.g. multimedia, adaptability) as (partly) unimportant. This result conflicts somewhat...

Bilingual electronic dictionaries contain collections of lexical entries in two languages, with explicitly declared translation relations between such entries. Nevertheless, they are typically developed in isolation, in their own formats and accessible through proprietary APIs. In this paper we propose the use of Semantic Web techniques to make translations available on the Web to be consumed b...

In recent years there has been a growing interest in representation and compression of signals by using dictionaries of basis functions other than the traditional dictionary of sinusoids. These new set of dictionaries include cosine packets, chirplets, Gabor functions, wavelets, and wavelet packets. In this paper Matching Pursuit and Basis Pursuit with finite dictionaries of convolutional splin...

Recent works aiming at making Linked Data dictionaries make use of the Lemon or OntoLex models. Application to existing dictionaries revealed the need for extensions to the model to properly deal with lexicographic data without loss of information. These works however focus on languages found in Europe, and thus let the issue of Est-Asian lexicography for future exploration. This paper provides...

A variable-toxed length encoding procedure is a mapping from a dictionary of variable length strings of source outputs to the set of codewords of a given length. For memoryless sources, the Tunstall procedure can be applied to construct optimal uniquely parsable dictionaries and the resulting codes are known to work especially well for sources with small entropies. We introduce the idea of plur...

In this paper, a new method for acquiring bilingual dictionaries from on-line text corpora is presented. The method merges rule-based techniques for obtaining dictionaries from structuralised data, such as paper dictionaries (in electronic form) or on-line glossaries, with methods used by aligning tools, such as GIZA. The basic idea is to search for anchor words such as abstract or keywords fol...

The paper presents a semi-automatic approach to creating sentiment dictionaries in many languages. We first produced high-level goldstandard sentiment dictionaries for two languages and then translated them automatically into third languages. Those words that can be found in both target language word lists are likely to be useful because their word senses are likely to be similar to that of the...
