||<style="border:0;padding-left:30px;padding-bottom:5px">I will present a semantic analyzer SemETAP, which is a module of a linguistic processor ETAP designed to perform analysis and generation of NL texts. We proceed from the assumption that the depth of understanding is determined by the number and quality of inferences we can draw from the text. Extensive use of background knowledge and inferences permits to extract implicit information.||
||<style="border:0;padding-left:30px;padding-bottom:0px">Salient features of SemETAP include: ||
||<style="border:0;padding-left:30px;padding-bottom:0px">— knowledge base contains both linguistic and background knowledge;||

||<style="border:0;padding-left:30px;padding-bottom:15px">Complex networks, which have found application in the quantitative description of many different phenomena, have proven to be useful in research on natural language. The network formalism allows to study language from various points of view - a complex network may represent, for example, distances between given words in a text, semantic similarities, or grammatical relationships. One of the types of linguistic networks are word-adjacency networks, which describe mutual co-occurrences of words in texts. Although simple in construction, word-adjacency networks have a number of properties allowing for their practical use. The structure of such networks, expressed by appropriately defined quantities, reflects selected characteristics of language; applying machine learning methods to collections of those quantities may be used, for example, for authorship attribution.||

However, the scheme does not adequately represent coordination, i.e., structures involving conjunctions. In this talk, we propose representations of two aspects of coordination which have not so far been properly represented either in UD or in dependency grammars: coordination of unlike grammatical functions and nested coordination.||

The results of the experiments show that as the length of the context increases, the differences between languages with large and small data resources also increase. Surprisingly, even minimal changes in the command (adding the possibility that the information does not exist) cause a significant decrease in effectiveness, especially with longer texts.||

http://zil.ipipan.waw.pl/seminarium-online Veje – a future treebank of Slovenian dialectal texts  Talk in English.

Slovenian dialect research has produced a lot of literature, but not as many data sources. The lack of available syntactically annotated corpora limits research for those, who do not have access to native speakers. This talk presents the first phase of Veje – to become a Slovenian dialect treebank. The present version of the pipeline is designed to reduce the manual work. The pipeline has two modules – normalization and annotation. In the first stage, dialectal surface forms are normalized towards standard Slovenian through a sequence of corrected lexical replacements, deterministic phonological rules, Sloleks-based morphological validation, and a constrained GaMS residual corrector. The process preserves token order and alignment wherever possible and records substitutions that cannot be morphologically verified for later review. In the second stage, normalized sentences are parsed with the non-standard Slovenian CLASSLA-Stanza model, while SloBERTa identifies whatever could not be normalized and sends it to GaMS for a second check of the annotation. The resulting extended CoNLL-U representation retains the original dialect form alongside its normalized equivalent, Universal Dependencies annotation, dialect metadata, and audit information. The current output is intentionally silver-standard: native speakers and dialectologists will correct selected data into a gold subset, which will subsequently support evaluation and model fine-tuning. I will also show the web-platform developed based on user needs study held with corpora users.
