Tool Support and Data Management for Business Analytics

Azarm, Mana January 2011 (has links)
The data delivery architectures in most enterprises are complex and under documented. Conceptual business models and business analytics applications are created to provide a simplified, and easy to navigate view of enterprise data for analysts. But the construction of such interfaces is tedious, manually intensive to build, requiring specialized technical expertise, and it is especially difficult to map exactly where data came from in the organization. In this paper we investigate how two aspects (lineage and requests for data i.e. semantics and new reports) can be addressed by tying metadata documentation to a systematic data delivery architecture in order to support business analytics applications. We propose a tool framework that includes a metadata repository for each step in the data delivery architecture, a web based interface to access and manage that repository and mapping tools that capture data lineage to support step by step automation of data delivery.

Att trassla ut taggar : Om fanfictions tillgängliggörande och arkivering på internet / To detangle tags : About the accessibility and archiving of fanfictions online

Fältskog, Natalia January 2020 (has links)
The aim for this study is to investigate how the website archiveofourown.org dedicates itself to archiving and organizing fanfiction. This study aims to find answers for how archiveofourown makes fanfiction accessible for the fanfiction community, both in the present time and in its function as an archive. Building from Derrida's thoughts about how power control what is archived and therefore the exclusion from archives is a threat to de-mocracy. Paired with the idea from De Kosnik about fanfiction archives archiving a part of media that does not exist this essay will argue for the importance of the free-form tagging of meta-data in correlation to user-uploaded fanfiction on www.archiveofourown.org and the archiving of said meta-data as well as fanfiction. The thesis also discusses the importance for fandom-community to own their archives due to censorship and accessibility. In this thesis the concept of gender as a performative discourse is important to the understanding of women's labour in fanfiction communities.Material for this study have been gathered from the website archiveofourown.org during the spring of 2020. By doing a close reading of the material published by the site and the users the study presents how the tagging sys-tem works and analyses the findings with help of previous research. The results of this study show that the free form tagging system of metadata is important for the fanfiction community. By allowing this form of tagging the culture of the online space can be preserved. This study finds that most producers and consumers of fanfic-tion identify as female, and therefore argues that the use of volunteer work on a site with material by and for female is problematic due to the issue that feminine coded values, like organizing and flexibility, suggests that the work is less technical and such less masculine than it would otherwise be perceived.According to the findings of this study the tagging systems of metadata has an important part in preserving internet history of those that may not have it preserved otherwise. It is also preserving part of other internet cultures such as the tagging culture on websites like tumblr.com. This is a two-year master's thesis in archival science.

Effektiv och transparent, men subjektiv och sårbar : En studie av arkivariers syn på den verksamhetsbaserade arkivredovisningen

Sundquist, Maria January 2017 (has links)
The focus of the thesis is to investigate how four university archivists perceive the functionality of the new Swedish process-oriented archival description system. University archivists are at the center of the study since the organizational structure of a university is process-oriented to some degree. However universities still have activities that are more challenging to view as processes, such as research. Universities were thus identified as a suitable candidate to analyze how process-oriented archival description functions in an environment that both is and is not clearly process-oriented. The research questions posed in this study are all related to the new archival description model, and archivists own experiences and views of the system. The main questions in the study concern the functionality of the system, its durability (if there is a repeated call for modification of the model), how the archival description system works with organizations that are not process-oriented, as well as if the system can operate as a finding aid in a long term perspective. The theoretical aim of the study is based around two different and sometimes contrasting views on the nature of archival records; namely the life cycle- and continuum-model. According to the life cycle-perspective records follow a linear-path from birth to death, reaching pre-destined pit stops along the way. The continuum theorists imagine records not as linear but as multifaceted, having multiple lives and never reaching a “death”-state. In Sweden, earlier research has shown that the life cycle-model has dominated the archival scene, but the new process-oriented archival description system could open up for a continuum-related approach. This study shows that no archivist made any statements that hinted in a continuum-way of thinking, and the results rather substantiated earlier research claiming the dominance of the life cycle-model. Investigation results show that three out of four archivists don’t believe that the archival description model is suitable for universities, as the organizational structure is not process-oriented. All of the archivists are struggling with describing activities as process-based, and three out of four archivists claim that description ends upcontrived. All archivists however concur that the positive effects of the system could result in government agencies increases transparency and accountability, but only if the system works as intended. The long term durability of the description model is also put in question from three out of four archivists. All archivists additionally regard the model as sensitive to organizational changes, and all universities are preparingfor and expecting numerous future modifications. The conclusion of the study is that the process-oriented archival description system is difficult to apply to organizations that have activities with unclear processes. The results furthermore indicate that the system needs continuous effort to maintain, due to the nature of ever changing organizations. As a finding aid the model is viewed as flawed, as the classification schema will be revised several times, which will certainly demand that the user have assistance in understanding the schema. All archivists claim that the archival function (and not the classification schema) of the university will be the main search tool for all users in the future.

NETWORK AND TOPOLOGICAL ANALYSIS OF SCHOLARLY METADATA: A PLATFORM TO MODEL AND PREDICT COLLABORATION

Lance C Novak (7043189) 15 August 2019 (has links)
The scale of the scholarly community complicates searches within scholarly databases, necessitating keywords to index the topics of any given work. As a result, an author’s choice in keywords affects the visibility of each publication; making the sum of these choices a key representation of the author’s academic profile. As such the underlying network of investigators are often viewed through the lens of their keyword networks. Current keyword networks connect publications only if they use the exact same keyword, meaning uncontrolled keyword choice prevents connections despite semantic similarity. Computational understanding of semantic similarity has already been achieved through the process of word embedding, which transforms words to numerical vectors with context-correlated values. The resulting vectors preserve semantic relations and can be analyzed mathematically. Here we develop a model that uses embedded keywords to construct a network which circumvents the limitations caused by uncontrolled vocabulary. The model pipeline begins with a set of faculty, the publications and keywords of which are retrieved by SCOPUS API. These keywords are processed and then embedded. This work develops a novel method of network construction that leverages the interdisciplinarity of each publication, resulting in a unique network construction for any given set of publications. Postconstruction the network is visualized and analyzed with topological data analysis (TDA). TDA is used to calculate the connectivity and the holes within the network, referred to as the zero and first homology. These homologies inform how each author connects and where publication data is sparse. This platform has successfully modelled collaborations within the biomedical department at Purdue University and provides insight into potential future collaborations.

An Asynchronous Meta-Data Driven Web UI for Pricing of Structured Products

Lindström, Anders January 2015 (has links)
In the process of building maintainable and customizable software used and displayed in different mediums, a user interface (UI) that is auto-generated from meta-data can be built. That way minimal effort can be made when customizing the software. This thesis took place at the financial software company SunGard. Traders have requested a web based solution to one of SunGard's financial softwares, and will be used for managing structured products. The solution had to work with some already defined web and server components that SunGard is using. The web tool used for making a prototype and evaluating the suitability was AngularJS. As a result it was found that it was possible to create a meta-data driven UI. Some programmatic design issues when generating the UI are discussed.

A database solution for scientific data from driving simulator studies.

Rasheed, Yasser January 2011 (has links)
Many research institutes produce a huge amount of data. It was said by someone that “We are drowning in data, but starving of information”. This is particularly true for scientific data. The needs and the advantages of being able to search data from different experiments are increasing in order to look for differences and similarities among them and thus doing Meta studies. A Meta-study is the method that takes data from different independent studies and integrate them using statistical analysis. If data is well described and data access is flexible then it is possible to establish unexpected relationships among data. It also helps in the re-using of data from studies that have already been conducted which saves time, money and resources. In this thesis, we explore at the ways to store data from experiments and to make finding cross-experiments more efficient. The main aim of this thesis work is to propose a database solution for storing time series data generated by different simulators and to investigate the feasibility of using it with ICAT. ICAT is a metadata system used for searching and browsing of scientific data. This thesis has been completed in two steps. The first step is aimed at proposing an efficient database solution for storing time series data. The second step is aimed at investigating the feasibility of using ICAT and proposed database solution together. We found out that it is feasible to use ICAT as a metadata system for scientific studies. Since it is free and open source, it can be linked to any system and customized according to the needs.

Moving from Fear towards Unity among Intergroup Dialogue Participants in Israel-Palestine: Findings from a Qualitative Meta-Data-Analysis

Treakle, Jesse W. 01 January 2017 (has links)
This qualitative meta-data-analysis was designed to identify themes of experience of Israeli Jewish and Palestinian Arab intergroup dialogue participants. A review of the literature indicated a scarcity of research that describes the ‘meaning-making’ processes that these participants undergo while engaged in structured intergroup dialogue, and this study was designed to address that shortage. The analyst conducted a targeted search of academic journal articles and Ph.D. dissertations published after 1999. The result of this search was a set of 17 primary reports, and the findings of this study are based on the verbatim quotations of Israeli Jewish and Palestinian Arab intergroup dialogue participants as cited within the set of primary reports. The analyst performed a thematic analysis of said quotations and, guided by contact theory, social identity theory, and intersubjectivity theory, concluded that Israeli Jews, Palestinian Arab citizens of Israel, and Palestinian Arabs in the Occupied Territories all enter dialogue carrying varying levels of fear and anger; and if they remain dedicated to dialogue processes, they eventually—to varying degrees—seek truth, pursue justice, and realize unity. This study’s primary contribution is its explication of the specific areas intergroup dialogue facilitators and researchers need to focus in Israel-Palestine. The findings indicate that more research needs to be conducted on inter-religious, narrative, and activist models. Furthermore, the data evidences the presence of geotheological influences on participant perspectives. Overall, the findings of this dissertation are consistent with previous research that affirms the power of dominant group narratives to sustain intractable conflict and the necessity of intergroup dialogue to foster cross-group friendships that can overcome intractable conflict.

Web Information Behaviors of Users Interacting with a Metadata Navigator

McMillan, Tyson DeShaun 12 1900 (has links)
The web information behaviors of users as they interacted with a metadata navigator, the Personal Information (PI) Agent, and reflected upon their interaction experiences were studied. The process included studying the complete iterative (repeated) cycle of information needs, information seeking, and information use of users interacting with an internet-based prototype metadata PI Agent tool. Detlor’s theory of web information behaviors of organizational users was utilized as a theoretical foundation for studying human-information interactions via the PI Agent tool. The qualitative research design allowed for the use of triangulation within the context of a one-group pretest-posttest design. Triangulation occurred in three phases: (a) observe, (b) collect, and (c) reflect. Observations were made as participants solved three problem situations. Participants’ computer log and print screen data were collected, and follow-up interviews were conducted once all posttest sessions ended to enable users to reflect on their experiences. The three triangulation phases ensured saturation of data and greater depth regarding the participants’ information behaviors. Content analysis occurred via exploratory pattern analysis using the posttest Problem Steps Recorder (PSR) log data and on the six interviewees’ follow-up interview data. Users engaged in iterative cycles of information needs, information seeking, and information use to resolve the presented problem situations. The participants utilized the PI Agent tool iteratively to eliminate their knowledge gaps regarding the presented problem situations. This study was the first to use PSR log data for capturing evidence of the iterative search process as defined by Detlor. The implications for best practices were inspired by participant feedback, and recommendations for further study are made.

Reconfigurable Application Networks through Peer Discovery and Handovers

Gioacchino Cascella, Roberto January 2003 (has links)
This Master thesis work was carried out at theWireless Center at KTH and it is part of a pilot project. This thesis is conducted for the Institute for Microelectronics and Information Technology (IMIT) at the Royal Institute of Technology (KTH) in Stockholm (Sweden) and for the Department of Telecommunications at Politecnico di Torino in Turin (Italy). This thesis addresses an area with significant potential for offering services to mobile users. In such a scenario users should have minimal interaction with applications which, by taking into account available context information, should be able to make decisions, such as setting up delivery paths between peers without requiring a third party for the negotiation. In wireless reconfigurable networks, the mobile users are on the move and must deal with dynamic changes of network resources. In such a network, mobile users should be able to contact other peers or resources by using the current route. Thus although manual configuration of the network is a possible solution, it is not easily used because of the dynamic properties of the system which would demand too much user interaction. However, existing discovery protocols fall short of accomodating the complexity of reconfigurable and heterogeneous networks. The primary objective of this thesis work was to investigate a new approach at the application level for signaling by taking advantage of SIP’s features. The Session Initiation Protocol (SIP) is used to provide naming and localization of the user, and to provide functionality to invite users to establish sessions and to agree on communication parameters. The Specific Event Notification of the SIP protocol provides a framework for the notification of specific events and I believed that it could be instantiated as solution to the problem for reconfigurable application networks. This thesis proposes a method for providing localization information to SIP User Agents in order to establish sessions for service discovery. Furthermore, this method should consider context meta-data to design strategies effective in heterogeneous networks. A viable solution must support (re)location of users at the application layer when they roam between different wireless networks, such as GPRS and WLAN. An analysis of the implications of the proposed model is presented; in this analysis emphasis has been placed on how this model interacts with existing services.
