This paper presents the work in progress on ELEXIS-SR corpus, the Serbian addition to the ELEXIS multilingual
annotated corpus (Martelli et al., 2023), comprising semantic annotations and word sense repositories. The ELEXIS
corpus has parallel annotations in ten European languages, serving as a cross-lingual benchmark for evaluating
low and medium-resourced European languages. The focus in this paper is on multiword expressions (MWEs) and
named entities (NEs), their recognition in the ELEXIS-SR sentence set, and comparison with annotations in other
languages. The first steps in building the Serbian sense inventory are discussed, and some results concerning
MWEs and NEs are analysed. Once completed, the ELEXIS-SR corpus will be the first sense annotated corpus
using the Serbian WordNet (SrpWN). Finally, ideas to represent MWE lexicon entries as Linguistic Linked-Open
Data (LLOD) and connect them with occurrences in the corpus are presented
