In this paper, I describe systems and prototypes we created in the natural language processing group at Lund to extract structured knowledge from text. Starting from syntactic and semantic parsingcomponents,wedevelopedapplicationsthatcanhandlelargecorpora,typicallycomplete Wikipedia versions consisting of millions of documents and process text to identify entities and the relations between them.

Abstract in UndeterminedThe success of the Wii and of the iPhone together with the persisting problem of displaying information on the small screens of mobile devices is currently pushing the development of non-visual interaction channels such as gestures, tactile/haptic interaction and sound. This development presents both potential and risk, since new channels of interaction may result either in
La Petite Ceinture is a mysterious abandoned rail line at the heart of Paris. Once a major connector between the different train stations of the French capital, it now quietly rests hidden, as one of Paris’ long forgotten green corridors. In 2006, a joint collaboration between the elected representatives and the train company tried to come up with a plan to open it up for the public to enjoy. Th
“Dzud” is a unique winter weather phenomenon with devastating effects on livestock and the people of Mongolia. As climate change continues to intensify, the social-ecological impacts of dzud worsens. This qualitative case study analyses the Mongolian government’s response to dzud and its following social-ecological impacts from second-hand material. A measuring instrument based on social-ecologica
The conventional method to manufacture prosthetic arms is a time-\\consuming and complicated process. It is a process that has many manual steps that allow much room for human errors. With today's technology advancement it is possible to offer a more efficient technology that can replace the conventional manufacturing method of prostheses. This master thesis aims to develop a new way of manufa
The purpose of the research thesis is to examine which steps are evident in the development of innovations in family businesses, and to determine which steps of the innovation process are affected by traditions and knowledge. An abductive method was used for the thesis, together with a qualitative research consisting of interviews with respondents from the two case study companies Engelholmsglass
This Bachelor project will study convolutional neural networks created for image classification. Furthermore, it will specifically use an explanatory model for how the network decided a certain classification output. This is to increase the interpretability of the network. However, the completeness of the explanatory model needs to be high for it to be useful. A saliency map of how valuable each i
Technological advancements continue to drive changes in our modern society. To keep up with these changes, it is of utter importance to stay competitive, whilst remaining flexible enough to be prepared for future changes. A sector which has struggled in this aspect, traditionally, is self-employed craftsmen - individuals who run a business based upon an aptitude for their trade. This study focuses
As a consequence of the Green New Deal and its refraining from carbon pricing policies, this study aims to examine further why actors supporting the new policy framework are taking a distance from all previous carbon pricing methods such as taxations och cap and trade systems. The study has been conducted through the methodology of an idea analysis, where arguments gathered from four election camp
This contribution concerns the development of generic methods and tools for robust optimal control of high-pressure liquid chromatographic separation processes. The proposed methodology exploits a deterministic robust formulation, that employs a linearization of the uncertainty set, based on Lyapunov differential equations to generate optimal elution trajectories in the presence of uncertainty. Co
In this paper, we present a random puncturing analysis of low-density parity-check (LDPC) code ensembles. We derive a simple analytic expression for the iterative belief propagation (BP) decoding threshold of a randomly punctured LDPC code ensemble on the binary erasure channel (BEC) and show that, with respect to the BP threshold, the strength and suitability of an LDPC code ensemble for random p
Despite its long history, the Theory of Characteristic Modes has only been utilized in antenna design for perfect electric conductors. This is due to computational problems associated with dielectrics and magnetic materials. In particular, the symmetric form of the PMCHWT surface formulation for the Method of Moments (MoM) solves for both external (real) and internal (non-real) resonances of a str
Popular Abstract in Swedish Att ha en allvarlig hjärtsjukdom är oftast förknippat med oro och rädsla. När det bestäms att patienten ska genomgå en planerad hjärtoperation, kan det vara avgörande för patientens och de närståendes välbefinnande hur de bemöts av all hälso- och sjukvårdspersonal, som de kommer i kontakt med under väntetiden samt vilket stöd de då upplever. Att korrekt och saklig inforPatients waiting for cardiac surgery often consider the period from the decision for surgery to the time for the operation as long, heavy and dreary. Therefore, it is important that patients are supplied with structured oral and written information regarding their disease and its treatment, so that they are able to understand and discuss the forthcoming operation, the risk of complications and the
It has previously been shown by the authors that the pre-chamber ignition technique operating with fuel-rich pre-chamber combustion strategy is a very effective means of extending the lean limit of combustion with excess air in heavy duty natural gas engines in order to improve indicated efficiency and reduce emissions. This article presents a study of the influence of pre-chamber volume and nozzl
Shrines and Souls provides a multi-layered contextualization of the article on religious liberty in the Universal Declaration of Human Rights (Article 18), which was propounded by the United Nations General Assembly on December 10, 1948. It shows how the framers of the Declaration decided to break with some of the conventional ways of framing religious liberty in international law, by foregroundin
This paper presents the results of an explorative study on the strategies and tactics applied by the mechanical designer during the later phases of the design process. The method chosen for this study is experiment-based, which is appropriate for an in-depth examination of the designer's activities. Six experiments have been run based on three dimensions: 1) the carrying out of basic design tasks
The aim of this report is to investigate the possibilities of an automated process which will identify and separate worn out granules and thus ensure an optimum cleaning performance. Research shows that some users are not following the recommendations regarding when to change Granules, leading to reduced performance and a reduction in sales. The first phase of the project involves studying how th
This thesis investigates the role states play in promoting and directing a country’s development. More specifically, it is examined, which factors determine differences in state performance and why different types of states form. This is done through a comparative case study of Botswana and Zambia, two southern African countries that after a similar start into independence developed very different
