Pellet: A Practical OWL-DL Reasoner
2007
In this paper, we present a brief overview of Pellet: a complete OWL-DL reasoner with acceptable to very good performance, extensive middleware, and a number of unique features. Pellet is the first sound and complete OWL-DL reasoner with extensive support for reasoning with individuals (including nominal support and conjunctive query), user-defined datatypes, and debugging support for ontologies. It implements several extensions to OWL-DL including a combination formalism for OWL-DL ontologies, a non-monotonic operator, and preliminary support for OWL/Rule hybrid reasoning. Pellet is written in Java and is open source.
Q&A Scripts
2016
Šis projekts (tālāk – “Q&A Scripts”, “sistēma”) ir tīmekļa lietojumprogrammatūra tehniskā atbalsta un reklāmas nolūkiem. Tehniski, tā var būt izmantota vairākos nolūkos, kas iekļauj sevī jautājumu un atbilžu sistēmas (tālāk – tā saucamā “jautājumu koka”) izveidošanu, piemēram, testu izveidošanai, dialoga atspoguļošanai, telefona sarunas šablonu izveidošanai (kas var būt noderīgs ne tikai reklāmas nolūku zvanos, bet arī, piemēram, “uzticības tālruņos” un krīzes centru aprikojumā). Sistēmas lietotāji tiek iedalīti divās grupās: administratori un vienkāršie lietotāji, attiecīgi atšķiras viņu iespējas sistēmas lietošanā. Tā, administratoram ir iespēja veidot jaunos “jautājumu kokus”, rediģēt un…
Reaktīvās programmēšanas iespējas izmantojot RxJS bibliotēku
2016
Darbā tiek apskatīta lietotāja saskarnes notikumu asinhronā JavaScript programmēšana tīmekļa vidē. Galvenie darba jautājumi bija saprast, kādi bija iemesli asinhronās programmēšanas rašanās, kāpēc tā bija nepieciešama lietotāja saskarnes notikumu apstrādē. Kā lietotāja saskarne ir saistīta ar asinhrono programmēšanu. Darbā tiek apskatītas problēmas, kādas rodas lietotāja saskarnes notikumu apstrādē, izmantojot asinhrono programmēšanu. Darbā tiek apskatīta reaktīvā programmēšana – kas tā tāda ir, kas ir reaktivitāte, kā lietotāja saskarnes notikumus spēj apstrādāt reaktīvās programmēšanas bibliotēkas. Darbā izstrādāti praktiskie piemēri, lai salīdzinātu jQuery un RxJS kodu implementāciju, kā…
Natural Language-Based Knowledge Extraction in Healthcare Domain
2019
There is a growing amount of data in the databases of hospitals. These data could be exploited to alleviate the decision-making process of hospital managers, physicians and researchers. However, these types of end-users often lack the expertise necessary for extracting those data from the database. Several approaches exist in the field of how to allow non-programmers writing queries in a convenient manner, but none of them has yet reached fully satisfactory results. This paper sketches a solution to this problem by introducing means for writing queries in a keywords-containing natural language thus alleviating the query writing process for the end-user. Introducing this approach in the know…
R2D2 at GeoCLEF 2006: A Combined Approach
2007
This paper describes the participation of a combined approach in GeoCLEF-2006. We have participated in Monolingual English Task and we present joint work of the three groups or teams belonging to the project R2D2 with a new system, combining the three individual systems of these teams. We consider that research in the area of GIR is still in its very early stages, therefore, although a voting system could improve the individual results of each system, we have to further investigate different ways to achieve a better combination of these systems.
A Simple Solution for Improving the Effectiveness of Traditional Information Retrieval Systems
2005
In this paper we present a system based on the LSA paradigm to improve the performance of a traditional information retrieval system. The proposed system aims to improve both the recall and the precision capabilities of traditional search engines thanks to a semantic query expansion and a subsequent semantic results filtering. A collection of 650 documents has been used to compare the performances of the proposed system with a traditional search engine. Experimental trials show the effectiveness of the proposed solution
Dynamics of the termination of global alliances: probing the past, analyzing the present and defining the frontiers for future research
2022
PurposeWhile the number of global alliance terminations in the business world has grown steadily during the past few decades, the scholarly literature on strategic alliance (SA) termination remains limited. This research paper aims to perform a bibliometric analysis of the literature on alliance termination and propose a model for future research agenda that links the termination phase to the pre-alliance termination phase and post alliance termination phase.Design/methodology/approachA search query on global alliance termination identified a total of 69 research papers from the Scopus database, and a bibliometric analysis was performed using the bibliometrix R-package and VOSviewer. The an…
User experience-based information retrieval from semistar data ontologies
2019
The time necessary for the doubling of medical knowledge is rapidly decreasing. In such circumstances, it is of utmost importance for the information retrieval process to be rapid, convenient and straightforward. However, it often lacks at least one of these properties. Several obstacles prohibit domain experts extracting knowledge from their databases without involving the third party in the form of IT professionals. The main limitation is usually the complexity of querying languages and tools. This paper proposes the approach of using a keywords-containing natural language for querying the database and exploiting the system that could automatically translate such queries to already existi…
Ontology-based cooperation of information systems : contributions to database-to-ontology mapping and XML-to-ontology mapping
2010
This thesis treats the area of ontology-based cooperation of information systems. We propose a global architecture called OWSCIS that is based on ontologies and web-services for the cooperation of distributed heterogeneous information systems. In this thesis, we focus on the problem of connecting the local information sources to the local ontologies within OWSCIS architecture. This problem is articulated by three main axes: 1) the creation of the local ontology from the local information sources, 2) the mapping of local information sources to an existing local ontology, and 3) the translation of queries over the local ontologies into queries over local information sources.
Metadata-Oriented Language Model in Translingual Retrieval of Digital Data
2015
Translingual retrieval relies on processing a source language to retrieve digital document content in a target language. From the perspective of successful browsing digital catalogues, probability of retrieving the full text document in a language other than the query language is close to zero owning to the fact that it is not only the library collection, but especially a problem of matching the index terms with the query keywords which are assumed to be their translation equivalents. In addition, hardly any digital library system is incorporated with a translation component. As a result, such a matching is rather coincidental. Our approach to the translingual document retrieval problem is …
