DOCUMENT MANAGEMENT USING CLUSTERING ALGORITHMS
2015
Document management systems are complex systems, which offer services as storage, versioning, metadata, security, as well as indexing and retrieval capabilities. Large numbers of documents could be automatically grouped into classes of documents, which contain similar information. Therefor we propose to use clustering methods in order to group the documents. Clustering is an important process in text mining used for groping documents based on their contents in order to extract knowledge. In this paper we will present some requirements for clustering algorithms for a document management system
Collimation of energy in medium-modified QCD jets
2012
The collimation of energy inside medium-modified jets is investigated in the leading logarithmic approximation of QCD. The Dokshitzer-Gribov-Lipatov-Altarelli-Parisi (DGLAP) evolution equations are slightly modified by introducing splitting functions enhanced in the infrared sector. As compared to elementary collisions in the vacuum, the angular distribution of the jet energy is found to broaden in QCD media.
Interpretation of journalistic photographs as an instrument of visual literacy education
2016
Images are produced, used and distributed on an enormous scale. However, the skills of understanding, interpreting and using images as well as thinking and learning in terms of images are taken for granted, and thus, they are not sufficiently taught and developed, especially in higher education. The need for introducing visual literacy into the curriculum was identified in late 1960s, but no concrete guidelines have followed. This study proposes to apply interpretation of journalistic photographs as an instrument of visual literacy education. The main focus is on the image interpretation process and the kinds of meanings viewers apply to a photograph in the interpretation process. In each o…
Evaluating End-user Support : Validating the Use of Multiple Media in a CSCW Application
2006
Human-centred views on information systems are gaining more and more attention in IS community. The need to evaluate information systems from such a perspective is thus evident. In this paper, we exploit our earlier developed theoretical framework for evaluating end-user support in information systems, and demonstrate its usage in validating the use of multiple communication and collaboration media in a CSCW application. The evaluation is performed in terms of user perception in ISD process, users’ role in organizational information processing, and users’ behavioural nuances. Our study shows that a context specific theoretical framework is useful in validating the empirical results of syste…
Cognitive Mimetics for AI Ethics : Tacit Knowledge, Action Ontologies and Problem Restructuring
2020
Ethics and ethical information processing are an important problem for AI development. It is important for self-evident reasons, but also challenging in its’ implications and should be welcomed by designers and developers as an interesting technical challenge. This article explores AI ethics as a design problem and lays out how cognitive mimetics could be used a method for its design. AI ethics is conceptualized as a problem of implementation on the one hand, and as a problem of ethical contents on the other. From the viewpoint of human information processing, ethics becomes a special case of ethical information processing - one that has deep implications in terms of AI abilities and inform…
Patvaļīga piekļūšana automatizētai datu apstrādes sistēmai. Ar to radītais kaitējums un problemātika
2016
Darbā tiek apskatīts viens no bīstamākiem un neparedzamiem noziedzīgiem nodarījumiem kas tiek dvti par kibernoziegumiem. Šo noziedzīgo nodarījumu skaits un sarežģītība pieaug ar katru gadu. Latvijā var sastapt vairākus kibernozieguma veidus. Viens no izplatītākajim ir paltvaļīga peikļūšana automatizētai datu apstrādes sistēmai, par kuru paredzēta kriminālatbildība Krimināllikuma 241.pantā. Izmeklējot šāda veida noziedzīgus nodarījumus rodas problēmas, kā parezi kvalificēt noziedzīgo nodarījumu, kam jāpievērš uzmanība, lai izmeklēšanas gala rezultātā noziedzīgs nodarījums netiktu kvalificēts pēc cita krimināllikuma panta. Pastāvot šāda veida noziedzīgo nodarījumu izmeklēšanas problēmām, Latv…
Investigating the effectiveness of a digital game-based task on the acquisition of word knowledge
2020
This study investigates the probable effect of a digital game-based vocabulary learning (DGBVL) task on the acquisition of some components of a word knowledge framework. In so doing, 124 Persian speakers (56 males and 68 females) were randomly assigned to either a control or an experimental group. The experimental group participants completed a DGBVL task for acquiring ten low-frequent inanimate object names, or lexical nouns, by playing a commercial adventure game. The control group participants practiced the same words in a fill-in-the-blank vocabulary acquisition exercise. In brief, first, all participants sat for a word-checklist and a proficiency test; next, they completed their tasks,…
A Contrastive Evaluation of Word Sense Disambiguation Systems for Finnish
2019
Aiempi saneiden alamerkitysten yksiselitteistämistä käsittelevä työ, kuten monet muut luonnollisen kielen käsittelyyn liittyvät tehtävät, on enimmäkseen keskittynyt englannin kieleen. Vaikka hieman työtä on tehty myös muilla kielillä, mukaan lukien uralilaiset kielet, vertailevaa arviointia suomen kielen saneiden alamerkitysten yksiselitteistämisestä ei ole tähän mennessä julkaistu huolimatta siitä, että tarvittavat leksikaaliset resurssit, erityisesti FinnWordNet, ovat jo pitkään olleet saatavilla. Tämä työ pyrkii korjaamaan tilanteen. Se tarjoaa tuloksia merkittävimpiä lähestymistapoja saneiden alamerkitysten yksiselitteistämiseen edustavista ohjelmista, sisältäen joitakin parhaiten engla…
What is a language error?
2022
Why are we so afraid of making mistakes? Students in language classes, speakers of non-standard varieties, professionals working abroad – we all share the anxiety of dropping the ball. But where does this anxiety come from? Why do we perceive certain linguistic features as errors in the first place? Is there any inherent faultiness in such features, or is a language error arbitrary? And if it is arbitrary, are errors less real? In this discussion, Maria Khachaturyan, Maria Kuteeva and Svetlana Vetchinnikova zoom in on the social life of variation in language and its uneasy relationship with our normative ideas. After that, Gunnar Norrman and Dmitri Leontjev give their comments. The discussi…
Verkkoproosa : tutkimus dialogisesta kirjoittamisesta
2007
This theoretical work scrutinizes poetical aspects of writing in the web (blogs, chat, forums). The practice of writing called web prose use the elements of speech and textualize it. This brings web prose near the tradition of literature, not as art, but as style of prose writing. By using H-G Gadamer`s hermeneutics, philosophy of conversation and poetics, I ask how the tradition of writing comes in to the web. Web is scrutinized from the aspects of poetics, dialogue and publicity. The work examines language and genre from the approach of the writing studies. Dialoque has an important function also in the web prose, when writing is getting closer to conversation. At last part I ask what cha…
