Decorating two-dimensional (2D) materials with transition-metal adatoms is an effective way to bring about new physical properties that are intriguing for applications in electronics and spintronics devices. Here, we systematically studied the coverage-dependent magnetic electronic of graphene decorated by Co adatoms, based on first-principles calculations. We found if coverage larger than 1/3[...

The practical challenge of creating a Hungarian e-mail reader has initiated our work on statistical text analysis. The starting point was statistical analysis for automatic discrimination of the language of texts. Later it was extended to automatic re-generation of diacritic signs and more detailed language structure analysis. Parallel study of three different languages Hungarian. German and En...

It is a widely accepted belief in natural language processing research that naturally occurring data is the best (and perhaps the only appropriate) data for testing text mining systems. This paper compares code coverage using a suite of functional tests and using a large corpus and finds that higher class, line, and branch coverage is achieved with structured tests than with even a very large c...

The usefulness of FrameNet is affected by its limited coverage and non-standard semantics. This paper presents some strategies based on Linguistic Linked Open Data to fully exploit and broaden its coverage. These strategies lead to the creation of a novel resource, Framester, which serves as a hub between FrameNet, WordNet, VerbNet, BabelNet, DBpedia, Yago, DOLCE-Zero, as well as other resource...

The present work is about automatic parsing of written texts using lexicalized grammars and large coverage language resources. More specifically, we concentrated our work on three domains : algorithmic, easy development of NLP applications useful in an industrial context, and deep syntactic parsing. Concerning the first point, we implemented new algorithms for the optimisation of local grammars...

Pattern-based approaches for Information Extraction typically apply a pattern learner to a set of domain-specific documents to generate extraction patterns that comprise the IE system. This limits the coverage of the system to the expressions and language constructs used within the training data. This research exploits the vast quantities of text readily available in large corpora, such as The ...

Based on the Sotscheck text corpus, we developped a new corpus that was specifically optimised for training phoneme-based recognition systems. Particular attention was payed on good coverage of phone transitions. Even though the resulting corpus is only slightly enlarged, it shows an increased phonetic coverage while maintaining a good phonetic balance. Results of phonetic statistical analysis ...

It seems that designing and implementing database engines may have become a lost art. Although most standard database text books [1] [2] [3] include ample coverage of algorithms for design and implementation database engines, many computer science programs seem to provide minimal coverage of file organizations, theoretical foundations, and algorithms necessary to build a database engine. The sy...

Designing text scripts that cover enough phonetic units and prosodic phenomena is very important when recording speech database for corpus based speech synthesis. When designing recording scripts for speech synthesis databases, a lot of effort is often placed on how to achieve maximal coverage of phonetic units in minimal speech recording. However, when we try to select sentences that have opti...
