  In recent years, word embeddings have been shown to improve the performance in NLP tasks such as syntactic parsing or sentiment analysis. While useful, they are problematic in representing ambiguous words with multiple meanings, since they keep a single representation for each word in the vocabulary. Constructing separate embeddings for meanings of ambiguous words could be useful for solving the Word Sense Disambiguation (WSD)...

  - Year 2015

  Semantic technologies appear as a step on the way to creating systems capable of representing the physical world as real time computational processes. In this context, the paper presents a toolchain for an ontology based knowledge management system. It consists of the ontology editor, FluentEditor and the distributed knowledge representation system, Ontorion. FluentEditor is a comprehensive tool for editing and manipulating complex...

• Retrieval with Semantic Sieve

  Publication

  • J. Szymański
  • H. Krawczyk
  • M. Deptuła

  - Year 2013

  The article presents an algorithm we called Semantic Sieve applied for refining search results in text documents repository. The algorithm calculates socalled conceptual directions that enables interaction with the user and allows to narrow the set of results to the most relevant ones. We present the system where the algorithm has been implemented. The system also offers in the presentation layer clustering of the results into...

• Open-Set Speaker Identification Using Closed-Set Pretrained Embeddings

  Publication

  • M. Affek
  • M. S. Tatara

  - Year 2022

  The paper proposes an approach for extending deep neural networks-based solutions to closed-set speaker identification toward the open-set problem. The idea is built on the characteristics of deep neural networks trained for the classification tasks, where there is a layer consisting of a set of deep features extracted from the analyzed inputs. By extracting this vector and performing anomaly detection against the set of known...

• Semantic Memory for Avatars in Cyberspace

  Publication

  • J. Szymański
  • T. Sarnatowicz
  • W. Duch

  - Year 2005

  Avatars that show intelligent behavior should have an access to general knowledge about the world, knowledge that humans store in their semantic memories. The simplest knowledge representation for semantic memory is based on the Concept Description Vectors (CDVs) that store, for each concept, an information whether a given property can be applied to this concept or not. Unfortunately large-scale semantic memories are not available....

• Semantic web services in L2L.

  Publication

  • M. Okraszewski
  • H. Krawczyk

  - Year 2004

  Ogromnym problemem współpracy istniejących bibliotek cyfrowych w kontekście używanych protokołów jest albo ograniczenie funkcjonalności systemu albo łamanie istniejących standardów komunikacji powodując utratę możliwości kooperacji z wieloma systemami. Technologia semantycznych usług sieciowych może zmienić tę sytuację przez umożliwienie komunikacji z usługą bez wcześniejszej znajmości protokołu stosowanego przez bibliotekę. W...
