It also aims at exposing the historical context of the making of that tool, from the perspective of digital humanities, to show its use for collecting, organizing, citing, formatting, sharing and historical contextualization of knowledge. Lélia Gonzalez's collection of documents from “Projeto Memória” (Memory Project) was used as an example of organization of information, as well as the tutorial regarding the use of Zotero platform as an Open Educational Resource (OER). Based on the qualitative and exploratory approach of the bibliographic survey that composes the theoretical foundation, the methodological procedures adopted on the comparative aspect of the reference management tools, Zotero and Mendeley, and the choice by Zotero for the organization of Lélia Gonzalez collection reflect the perspectives of the digital humanities, as well as the perspectives of open education for the application of workshops to researchers.

The purpose of the project was to develop an electronic resource that would provide a tutorial for students and offer opportunities for practice of measurement skills.

The aim of the study was to examine the implementation of digital preservation practices in academic libraries in South Africa in the light of the rapid changing information environment. The study looked into the strategies, systems and tools being employed to support digital preservation programmes and the costs associated with the various digital preservation programmes. The study was guided by various digital preservation theories and models,namely Davies’ (2000) Policy, Strategy and Resources (PSR) troika model, Kenney and McGovern’s (2003) three leg stool, Corrado and Moulaison‘s (2014) preservation triad and the Carnegie Mellon University’s (1990) Digital Preservation Capability Maturity (DPCM) model and Open Archival Information System (OAIS) model by OCLC (2002), underpinned by the survey research design, triangulation of questionnaires and document analysis as data collection methods. Out of 27 questionnaires distributed to academic institutions, 22 (81.5%) were completed. Quantitative data was analysed using descriptive analysis whilst content analysis was used for qualitative data obtained from document analysis. Findings revealed that academic libraries in South Africa were significantly affected by the changes to the digital environment. Most academic libraries face many challenges that hinder the effective implementation of digital preservation. The problems include: lack of funding, lack of skills and training and technology obsolescence. The study identified migration, bit preservation, replication and risk management approaches as the most widely implemented preservation strategies to address preservation challenges faced by academic libraries in South Africa. Although various preservation systems and tools are being developed to enable description, discovery, delivery and preservation of digital collections, there was expressed lack of awareness about digital preservation standards and preservation support organisations. The study also observed that, in some instances, the academic institutions were not fully involved in collaborative and partnerships with other institutions. By collaborating and partnering with other institutions, they would be exposed to new ideas, strategies and tools, and be able to acquire knowledge and skills needed to successfully preserve and manage their digital resources. The findings revealed that the implementation of policies and strategies, provision of adequate resources, sufficient funding and digital preservation knowledge and skills are some of the major factors influencing digital preservation sustainability in academic libraries. This study, therefore, recommends that these institutions can address some of the digital preservation challenges if they leverage on these factors. The study also made several recommendations on how digital preservation can be successfully implemented, and it further proposed a framework for preservation of digital resources in academic libraries, mapped to international preservation models and standards. / Information Science / D.

(English) The thesis examines the influence of information and communication technologies on the automation of library management processes and services as well as their applications, with a key consideration of the environment of the District Scientific Library of the city of Liberec. The introductory chapters briefly describe the development of basic international standards for data processing and communication networks in the world. The following chapters deal with the implementation of automated library management systems and networks in the Czech Republic in the early '90s, including accompanying projects that formed an inseparable part of the development. The development of automated library management processes and services in the District Research Library of the city of Liberec from the 90s till the end of 2010 becomes the core subject hereby examined. This is closely related to the parameters of the selection and application of the library management system, including the specific features thereof, as well as its internal utilization by librarians and its utilization by external users. The external use of the library management system has been evaluated through a survey of the use of online information sources and services sought by and provided to registered users. Taking into account the...

Indiana University-Purdue University Indianapolis (IUPUI) / The amount of information produced in the form of electronic free text in healthcare is increasing to levels incapable of being processed by humans for advancement of his/her professional practice. Information extraction (IE) is a sub-field of natural language processing with the goal of data reduction of unstructured free text. Pertinent to IE is an annotated corpus that frames how IE methods should create a logical expression necessary for processing meaning of text. Most annotation approaches seek to maximize meaning and knowledge by chunking sentences into phrases and mapping these phrases to a knowledge source to create a logical expression. However, these studies consistently have problems addressing semantics and none have addressed the issue of semantic similarity (or synonymy) to achieve data reduction. To achieve data reduction, a successful methodology for data reduction is dependent on a framework that can represent currently popular phrasal methods of IE but also fully represent the sentence. This study explores and reports on the benefits, problems, and requirements to using the predicate-argument statement (PAS) as the framework. A convenient sample from a prior study with ten synsets of 100 unique sentences from radiology reports deemed by domain experts to mean the same thing will be the text from which PAS structures are formed.

Indiana University-Purdue University Indianapolis (IUPUI) / Text mining is a process of extraction of knowledge from unstructured text documents. We have huge volumes of text documents in digital form. It is impossible to manually extract knowledge from these vast texts. Hence, text mining is used to find useful information from text through the identification and exploration of interesting patterns. The objective of this thesis in text mining area is to find compact but high quality frequent patterns from text documents related to neuroscience field. We try to prove that interactive sampling algorithm is efficient in terms of time when compared with exhaustive methods like FP Growth using RapidMiner tool. Instead of mining all frequent patterns, all of which may not be interesting to user, interactive method to mine only desired and interesting patterns is far better approach in terms of utilization of resources. This is especially observed with large number of keywords. In interactive patterns mining, a user gives feedback on whether a pattern is interesting or not. Using Markov Chain Monte Carlo (MCMC) sampling method, frequent patterns are generated in an interactive way. Thesis discusses extraction of patterns between the keywords related to some of the common disorders in neuroscience in an interactive way. PubMed database and keywords related to schizophrenia and alcoholism are used as inputs. This thesis reveals many associations between the different terms, which are otherwise difficult to understand by reading articles or journals manually. Graphviz tool is used to visualize associations.

Indiana University-Purdue University Indianapolis (IUPUI) / This thesis is aimed at creating a pipeline for analyzing DNA methylation epigenetics data and creating a data model structured well enough to store the analysis results of the pipeline. In addition to storing the results, the model is also designed to hold information which will help researchers to decipher a meaningful epigenetics sense from the results made available. Current major epigenetics resources such as PubMeth, MethyCancer, MethDB and NCBI’s Epigenomics database fail to provide holistic view of epigenetics. They provide datasets produced from different analysis techniques which raises an important issue of data integration. The resources also fail to include numerous factors defining the epigenetic nature of a gene. Some of the resources are also struggling to keep the data stored in their databases up-to-date. This has diminished their validity and coverage of epigenetics data. In this thesis we have tackled a major branch of epigenetics: DNA methylation. As a case study to prove the effectiveness of our pipeline, we have used stage-wise DNA methylation and expression raw data for Lung adenocarcinoma (LUAD) from TCGA data repository. The pipeline helped us to identify progressive methylation patterns across different stages of LUAD. It also identified some key targets which have a potential for being a drug target. Along with the results from methylation data analysis pipeline we combined data from various online data reserves such as KEGG database, GO database, UCSC database and BioGRID database which helped us to overcome the shortcomings of existing data collections and present a resource as complete solution for studying DNA methylation epigenetics data.

Indiana University-Purdue University Indianapolis (IUPUI) / In today's fast paced world, people have become increasingly interested in online communication to facilitate their lives and make it faster. This goes on from simple social interactions to more advanced actions like shopping on the internet. The presence of such activities makes it crucial for people to use their common sense and judgment to process all this information and evaluate what/who they trust and what/whom they do not. This process would have been much easier if the number of people in such networks is really small and manageable. However, there are millions of users who are hooked online every day. This makes the person very overwhelmed with his trusting decision, especially when it comes to interacting with strangers over the internet, and/or buying personal items, especially expensive ones. Therefore, many trust models have been proposed by computer scientists trying to evaluate and manage the trust between users using different techniques and combining many factors. What these computer scientists basically do is coming up with mathematical formulas and models to express trust in online networks and capture its parameters. However, social scientists are the people better trained to deal with concepts related to human behaviors and their cognitive thinking such as trust. Thus, in order for computer scientists to support their ideas and get a better insight about how to direct their research, people like social scientists should contribute. With this in mind, we realized in our group work the importance of such contribution, so we came up with the idea of my research work. In my search, I tried to find how these social scientists think and tackle a dynamic notion like trust, so we can use their findings in order to enhance our work and trust model. Through the chapters, I will discuss an already developed trust model that uses measurement theory in modeling trust. I will refer back to this model and see how other social scientists dealt with some of the issues encountered by the model and its functionality. Some small experiments have been done to show and compare our results with social scientists results for the same matter. One of the most important and controversial points to be discussed from social scientists' point of view is whether trust is transitive or not. Other points to be discussed and supported by social scientists' research include aggregation, reputation, timing effects on trust, reciprocity, and experience effects on trust. Some of these points are classified into trust mapping categories and others are related to trust management or decision making stages. In sum, this work is a multidisciplinary study of trust whose overall goal is to enhance our work and results, as computer scientists.

The use of the digital school library depends on many factors, including end-users‘ acceptance. The issue of designing information systems that will be used appropriately is growing and thus user acceptance of new technology is now receiving much attention by researchers. Without acceptance, discretionary users will seek alternatives, while even dedicated users will most likely manifest dissatisfaction, negating many, if not all, the presumed benefits of the digital library. Whereas the traditional focus of digital libraries has drawn research on technological developments, there is a call for user-focused research. This study sought to identify the dynamics of elementary children‘s (11- to 13- year olds) decision-making in the context of accepting or resisting making use of digital school libraries at Crawford Preparatory Pretoria School in Gauteng. To be accepted, the digital library must satisfy basic usability requirements and be perceived as useful by the children. The constructs of the Technology Acceptance Model, perceived ease of use and perceived usefulness were used to generate an understanding of acceptance of the digital school libraries. The study adopted a quantitative case study research approach to compare the empirical data and the TAM theory. Data triangulation of a wide range of data collection methods, including observation, questionnaires, focus groups and tasks given to the children to work on using the International Children‘s Digital Library was analysed. The findings revealed that, just like adults, children make decisions regarding accepting and using the digital school library based on how easy it is to use and how relevant it is to their needs. The study recommends that software designers, teachers and librarians work with the children when designing digital school libraries to ensure that their acceptance factors are taken into consideration when designing for them. / Information Science / M.

This research investigated the potential benefits, risks and challenges, innovation properties and viability of cloud computing for records management on an Australian organisation within the mining software development sector. This research involved the use of a case study results analysis as well as a literature analysis. The literature analysis identified the ten potential benefits of cloud computing, as well as the ten risks and challenges associated with cloud computing. It further identified aspects, which needed to be addressed when adopting cloud computing in order to promote innovation within an organisation. The case study analysis was compared against a literature review of ten potential benefits of cloud computing, as well as the ten risks and challenges associated with cloud computing. This was done in order to determine cloud computing’s viability for records management for Company X (The company in the case study). Cloud computing was found to be viable for Company X. However, there were certain aspects, which need to be discussed and clarified with the cloud service provider beforehand in order to mitigate possible risks and compliance issues. It is also recommended that a cloud service provider who complies with international standards, such as ISO 15489, be selected. The viability of cloud computing for organisations similar to Company X (mining software development) followed a related path. These organisations need to ensure that the service provider is compliant with laws in their local jurisdiction, such as Electronic Transactions Act 1999 (Australia, 2011:14-15), as well as laws where their data (in the cloud) may be hosted. The benefits, risks and challenges of records management and cloud computing are applicable to these similar organisations. However, mitigation of these risks needs to be discussed with a cloud service provider beforehand. From an innovation perspective, cloud computing is able to promote innovation within an organisation, if certain antecedents are dealt with. Furthermore, if cloud computing is successfully adopted then it should promote innovation within organisations. / Information Science / M. Inf.
