The paper describes a system for automatic summarization in English language of online news data that come from different non-English languages. The system is designed to be used in production environment for media monitoring. Automatic summarization can be very helpful in this domain when applied as a helper tool for journalists so that they can review just the important information from the news channels. However, like every software solution, the automatic summarization needs performance monitoring and assured safe environment for the clients. In media monitoring environment the most problematic features to be addressed are: the copyright issues, the factual consistency, the style of the text and the ethical norms in journalism. Thus, the main contribution of our present work is that the above mentioned characteristics are successfully monitored in neural automatic summarization models and improved with the help of validation, fact-preserving and fact-checking procedures.

This paper presents a semantic classification of reflexive verbs in Bulgarian, augmenting the morphosyntactic classes of verbs in the large Bulgarian Lexical Data Base - a language resource utilized in a number of Language Engineering (LE) applications. Thesemantic descriptors conform to the Unified Eventity Representation (UER), developed by Andrea Schalley. The UER is a graphical formalism, introducing the object-oriented system design to linguistic semantics. Reflexive/non-reflexive verb pairs are analyzed where the non-reflexive member of the opposition, a two-place predicate, is considered the initial linguistic entity from which the reflexive correlate is derived. The reflexive verbs are distributed into initial syntactic-semantic classes which serve as the basis for defining the relevant semantic descriptors in the form of EVENTITY FRAME diagrams. The factors that influence the categorization of the reflexives are the lexical paradigmaticapproach to the data, the choice of only one reading for each verb, top level generalization of the semantic descriptors. The language models described in this paper provide the possibility for building linguistic components utilizable in knowledge-driven systems.
