Research

Semantic analysis serves as the essential part of our research. We develope algorithms trying to discover hidden relationships between words and text spans according to words distribution in the corpora. Until now, we have successfully used this research in many areas (e.g. to improve the Language modeling, Named entity recognition, Sentiment analysis, Document classification, etc.).

Named Entity Recognition (NER) automatically identifies words or phrases of a special meaning in texts and classifies them into groups (e.g. persons, organizations, products, dates, cities, coutnries, product names).

Language models are crucial for many tasks in NLP. The goal of a language model is to estimate the probability of a given word sequence. Automatic speech recognition, optical character recognition, machine translation, and other areas heavily depend on the performance of the underlying language model.

Automatic summarization is the process of reducing a set of text documents in order to create a summary that retains the most important points of the original documents.

Sentiment Analysis is the detection of attitudes. The basic task is to automatically decide whether a piece of text (e.g. a review, a tweet, a blog post, or a general document) is positive or negative. Also the attitude’s polarity as well as the target, source, or complex types are detected.

Automatic document classification becomes very important for information organization and storage because of the fast increasing amount of electronic text documents and the rapid growth of the World Wide Web.

Artificial neural networks are computing systems inspired by the biological neural networks that constitute animal brains. Such systems learn to do tasks by considering examples, generally without task-specific programming.
