1. **[Learning to Identify Arabic and German Dialects using Multiple Kernels](https://md.research.elamur.ai/free/en/papers/ionescu-2017-learning-identify-arabic-german-dialects/)** *(2017 · 64 citations)* The paper describes the UnibucKernel entry to two closed dialect-identification shared tasks at the DSL 2017 Challenge (VarDial).
2. **[UnibucKernel: An Approach for Arabic Dialect Identification Based on Multiple String Kernels](https://md.research.elamur.ai/free/en/papers/ionescu-2016-unibuckernel-approach-arabic-dialect-identification/)** *(2016 · 53 citations)* The paper addresses Arabic Dialect Identification (ADI) in the closed track of the DSL 2016 Challenge. Systems had to assign each text to one of five classes: Modern Standard Arabic (MSA) or one of four dialects. The data are ASR transcripts of Broadcast News speech, so they may contain recognition errors. The…
3. **[UnibucKernel Reloaded: First Place in Arabic Dialect Identification for the Second Year in a Row](https://md.research.elamur.ai/free/en/papers/butnaru-2018-unibuckernel-reloaded-first-place-arabic/)** *(2018 · 39 citations)* The paper describes UnibucKernel, the system that won the closed Arabic Dialect Identification (ADI) task at VarDial 2018.
4. **[Improving the results of string kernels in sentiment analysis and Arabic dialect identification by adapting them to your test set](https://md.research.elamur.ai/free/en/papers/ionescu-2018-improving-results-string-kernels-sentiment/)** *(2018 · 22 citations)* The paper asks whether string kernels, which already lead several text classification benchmarks, can gain further accuracy by using the unlabeled test set during training.
