Chunk Smarter, Retrieve Better: Enhancing LLMs in Finance : An Empirical Comparison of Chunking Techniques in Retrieval Augmented Generation for Financial Reports
Get PDFThis thesis investigates how Retrieval-Augmented Generation (RAG) improves the ability of Large Language Models (LLMs) to filter information from financial documents. For this task, we first develop NorwegianFinanceQA, a dataset containing 433 queries from the financial reports of 9 Norwegian companies, divided into text- and table-related queries. Next, we evaluate the retrieval accuracy and efficiency of RAG systems with different chunking techniques: character-based, recursive, and semantic splitting. Additionally, we propose a table-specific summarization approach. Our results suggest that table summaries achieve perfect accuracy for table queries while at the same time increasing efficiency. However, this improvement comes at the expense of text-query performance. Our findings highlight the importance of tailored chunking strategies when using LLMs and RAG systems for information retrieval in a financial context
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Verdsettelse av Mowi ASA
Get PDFFormålet med semesteroppgaven er å verdsette aksjeselskapet Mowi i tillegg til å estimere deres aksjekurs per 31.12.22. Verdsettelsen utføres på bakgrunn av en fundamental verdsettelsesmetode som baserer seg på totalkapitalen, samt en markedsbasert verdsettelse som baserer seg på ulike multipler. Motivasjonen for oppgaven er å gjennomføre en verdsettelse av Mowi for å kunne komme med en kjøps- eller salgsanbefaling til interessenter i selskapet.
Metoden benyttet for å komme frem til en løsning på vår problemstilling er å ta for oss Mowi ASA som selskap og en bransjebeskrivelse. Videre tar vi for oss en strategisk analyse. Den strategiske analysen brukes som verktøy for å avdekke potensielle muligheter og utfordringer selskapet møter. De interne forholdene blir synliggjort gjennom en SVIMA-analyse som tar for seg styrker og svakheter. De eksterne forholdene som vil påvirke selskapet avdekkes gjennom bruken av en PESTEL-analyse og Porters fem konkurransekrefter. De interne og eksterne forholdene oppsummeres i SWOT-analysen. I den strategiske analysen fant vi ut at Mowi sine konkurransefortrinn er deres markedsposisjon, merkevare og integrerte verdikjede.
I regnskapsanalysen tar vi for oss den økonomiske situasjonen selskapet befinner seg i på bakgrunn av historiske data. Nøkkeltallene som er beregnet i regnskapsanalysen er, lønnsomhet, soliditet, likviditet og finansiering, som er de fire mest sentrale forholdene knyttet til økonomistyring. Regnskapsanalysen viser gode tall for økonomistyringen i Mowi og de har et godt grunnlag for videre drift og utvidelse.
Våre funn fremkommer i en fundamental verdsettelse, basert på avkastningskrav og prognoser for fremtidige kontantstrømmer, med en estimerte aksjekurs per 31.12.2022 på 159.76 NOK. I tillegg til en markedsbasert verdsettelse hvor vi kom frem til en estimerte aksjekurs per 31.12.2022 på 207.4 NOK på bakgrunn av estimerte multipler. Snittet av de estimerte verdiene gir oss en markedsverdi på 183.58 NOK per aksje. Aksjekursen på dette tidspunktet var 167.2 NOK. Det er en potensiell økning på 16.38 NOK tilsvarende 9.8% per aksje. Vi anbefaler derfor kjøp av aksjen til Mowi på bakgrunn av våre analyser gjort i denne oppgaven.The purpose of this thesis is to carry out a valuation of Mowi ASA in addition to estimating the company’s stock price pr 31.12.22. The valuation is carried out on the basis of a fundamental valuation based on the company`s total capital, in addition to a marked-based valuation which bases itself on different multiples. The motivation for the thesis is to carry out a valuation of Mowi in order to make a buy or sell recommendation to stakeholders in the company.
The thesis will first present an analysis of the company in question, Mowi ASA, before moving on to an analysis of the industry in which the company operates in. Secondly, the thesis will complete a strategic analysis to identify the company`s potential opportunities and challenges going forward. The external factors affecting the company in question will be made apparent through the use of analysing tools such as the PESTEL to look at macroeconomic factors, before Porters Five Forces will be applied to get an better understanding of the microeconomic factors. Next, the internal aspects of the company will be analysed using the SVIMA-tool to get a better understanding of the company’s strength and weaknesses. Based on the external and internal analysis the assignment will present a SWOT-analysis to summarize the results of the strategic analysis. After finishing the strategic analysis, the thesis has concluded that Mowi`s competitive advantages lies is their marked position, branding and integrated value chain.
In the accounting analysis we will look at Mowi`s economic situation based on historical data. The key figures computed in the accounting analysis is profitability, solvency, liquidity, and financing, which are the most central figures in regard to financial management. The accounting analysis shows good numbers for the financial management in Mowi ASA and concludes that the company have a good fundament for further expansion and operations.
Our findings result in a fundamental valuation, based on a required rate of return and forecasts for future cash flows, with an estimated share price as of 31.12.2022 at 159,76 NOK. In addition to a market-based valuation where we arrived at an estimated share price per 31.12.2022 of 207,4 NOK based on estimated multiples. The average of the estimated values gives us a market value of 183,58 NOK per share. The share price at this time was 167,2 NOK pr share which indicates the possibility for an upside of 16,38 NOK or 9,8% increase per share. We therefore recommend the purchase of shares in Mowi ASA on the basis of our analyse carried out in this thesis
