1. Novel Ranking-Based Lexical Similarity Measure for Word Embedding

Author

Dutkiewicz, Jakub and Jędrzejek, Czesław

Subjects
Computer Science - Computation and Language
Abstract

Distributional semantics models derive word space from linguistic items in context. Meaning is obtained by defining a distance measure between vectors corresponding to lexical entities. Such vectors present several problems. In this paper we provide a guideline for post process improvements to the baseline vectors. We focus on refining the similarity aspect, address imperfections of the model by applying the hubness reduction method, implementing relational knowledge into the model, and providing a new ranking similarity definition that give maximum weight to the top 1 component value. This feature ranking is similar to the one used in information retrieval. All these enrichments outperform current literature results for joint ESL and TOEF sets comparison. Since single word embedding is a basic element of any semantic task one can expect a significant improvement of results for these tasks. Moreover, our improved method of text processing can be translated to continuous distributed representation of biological sequences for deep proteomics and genomics., Comment: 7 pages; 1 page of references

8. Knowledge Graphs in Information Retrieval.

Abstract

This paper introduces an information retrieval model that leverages knowledge graphs, specifically tailored for Clinical Trials. In these scenarios, the document in question takes the form of a semi-structured clinical trial, containing details about enrolled patients, descriptions of experiments and procedures conducted during the trial, relevant diseases, and specific enrollment criteria. While the document retains a semi-structured format, the majority of the information is expressed in natural language. Queries in this context consist of specific patient characteristics, such as disease type, genetic information, and demographic data. The primary aim of this paper is to develop and utilize a knowledge graph capable of storing this information, including links to external resources like the Disease Ontology. We propose an Object-Relational model, which is then transformed into a knowledge graph. This graph is subsequently employed to identify semantic connections between concepts present in the clinical trials and those in the queries. These connections are then utilized to formulate a retrieval model for each aspect of the query. To achieve this, we design a relevance formula that incorporates weights to account for ontological relationships between concepts. We evaluate the effectiveness of our model by comparing the results with manual annotations. [ABSTRACT FROM AUTHOR]

23. Osada ze schyłkowej fazy kultury łużyckiej w Iwnie, pow. poznański, stanowisko 25/26

Author

Ciesielski, Mirosław and Dutkiewicz, Jakub

Abstract

The settlement at Iwno, the district of Poznań, site 25/26, provided new evidence for the recognition of the late phase of the Lusatian culture's development and its transformation into the Pomeranian culture towards the end of the Hallstatt period and at the beginning of the early pre-Roman Iron Age.
