Modelovanje i pretraživanje nad nestruktuiranim podacima i dokumentima u e-Upravi Republike Srbije / Modeling and searching over unstructured data and documents in e-Government of the Republic of Serbia

Nikolić Vojkan 27 September 2016 (has links)
<p>Danas, servisi e-Uprave u različitim oblastima koriste question answer sisteme koncepta u poku&scaron;aju da se razume tekst i da pomognu građanima u dobijanju odgovora na svoje upite u bilo koje vreme i veoma brzo. Automatsko mapiranje relevantnih dokumenata se ističe kao važna aplikacija za automatsku strategiju klasifikacije: upit-dokumenta. Ova doktorska disertacija ima za cilj doprinos u identifikaciji nestruktuiranih dokumenata i predstavlja važan korak ka razja&scaron;njavanju uloge eksplicitnih koncepata u pronalaženju podataka uop&scaron;te ajče&scaron; a reprezenta vna &scaron;ema u tekstualnoj kategorizaciji je BoW pristup, kada je u pozadini veliki skup znanja. Ova disertacija uvodi novi pristup ka stvaranju koncepta zasnovanog na tekstualnoj prezantaciji i primeni kategorizacije teksta, kako bi se stvorile definisane klase u slučaju sažetih tekstualnih dokumenata Takođe, ovde je prikazan algoritam zasnovan na klasifikaciji, modelovan za upite koji odgovaraju temi. Otežavaju a okolnost u slučaju ovog koncepta, koji prezentuje termine sa visokom frekvencijom pojavljivanja u upitma, zasniva se na sličnostima u prethodno definisanim klasama dokumenata Rezultati eksperimenta iz oblasti Krivičnog zakonika Republike Srbije, u ovom slučaju i studija, pokazuju da prezentacija teksta zasnovana na konceptu ima zadovoljavaju e rezultate i u slučaju kada ne postoji rečnik za datu oblast.</p> / <p>Nowadays, the concept of Question Answering Systems (QAS) has been used by e-government services in various fields as an attempt to understand the text and help citizens in getting answers to their questions promptly and at any time. Automatic mapping of relevant documents stands out as an important application for automatic classification strategy: query-document. This doctoral thesis aims to contribute to identification of unstructured documents and represents an important step towards clarifying the role of explicit concepts within Information Retrieval in general. The most common scheme in text categorization is BoW approach, especially when, as a basis, we have a large set of knowledge. This thesis introduces a new approach to the creation of text presentation based concept and applying text categorization, with the aim to create a defined class in case of compressed text documents.Also, this paper discusses the classification based algorithm modeled for queries that suit the theme. What makes the situation more complicated is the fact that this concept is based on the similarities in previously defined classes of documents and terms with a high frequency of appearance presented in queries. The results of the experiment in the field of the Criminal Code, and this paper as well, show that the text presentation based concept has satisfactory results even in case where there is no vocabulary for certain field.</p>

Guaman Poma's Legacy: Snapshots of Globalization, Identity, and Literacy through the Urban Amazonian Indigenous Intellectual Lens

Villamar, Roger Maurice 01 May 2014 (has links)
This dissertation initially utilizes the analogy of an Andean intellectual's magnum opus of resistant visual art and text created in the 1600s, to explore the impact of current global influences on the identity of Awajún and Wampís Amazonian students residing in Lima, the capital city of Perú. The participants in this study are urban Amazonian indigenous intellectuals applying to enter, currently studying in degree programs, or pursuing graduate degrees at local universities of Lima. Using an amalgamation of Photovoice and Photo-Elicitation components, digital photography, open-source applications, and computer technology, participants creatively expressed through their visual discourse what it means to be an Awajún or Wampís citizen of Perú during difficult times of conflictive global interests and unattended local needs. Between the time of preliminary fieldwork in the Amazonian communities in 2008, and the final interviews in Lima of 2010, violence erupted during a local road blockade in the Amazon that claimed the lives of Awajún/Wampís citizens and mestizo police officers alike. It is in that convoluted context where the dissertation delves into the views of the students and professionals regarding their own indigenousness, nationality, and "new" literacies, languages, and technologies that should be considered by the mestizo population and governments in order to make Perú a safer and more inclusive place for indigenous peoples from the Amazon.
