Transferring sentiment cross-lingually within and across same-family languages.

sentiment analysis bachelor thesis

1. Introduction

2. research questions and hypotheses.

  • A cross-lingual transfer is more successful for typologically similar languages than for typologically different languages.
  • A large annotated dataset in a distant-family language can overcome typological differences, unlike a small annotated dataset in a close-family language.
  • Initially, we propose a framework for unified deep learning that utilizes existing data labels from high-resource languages on low-resource datasets. We conduct rigorous experiments on languages within the same language family. We investigate how effectively sentiment classification abilities could be transferred.
  • Second, we demonstrate that, given multiple large-scale training datasets, our framework is superior to a straightforward setup for fine-tuning. Finally, we devise the optimal method for jointly training sentiment analysis systems in order to address the issue of insufficient resources for target languages.

3. Languages in the Study

4. related work, 4.1. sentiment analysis, 4.2. sentiment analysis in slavic languages, 4.3. cross-lingual sentiment analysis, sentiment analysis datasets.

  • Bulgarian: The Cinexio [ 51 ] dataset is composed of film reviews with 11-point star ratings: 0 (negative), 0.5, 1, … 4.5, 5 (positive). Other meta-features included in the dataset are film length, director, actors, genre, country, and various scores.
  • Croatian: Pauza [ 68 ] contains restaurant reviews from Pauza.hr4, the largest food ordering website in Croatia. Each review is assigned an opinion rating ranging from 0.5 (worst) to 6 (best). User-assigned ratings are the benchmark for labels. The dataset also contains opinionated aspects.
  • Czech: The CSFD [ 108 ] dataset was influenced by Pang et al. [ 109 ]. It includes film reviews from the Czech Movie Database ( http://www.csfd.cz accessed on 10 September 2023). Every review is classified as either positive, neutral, or negative.
  • English: The Multilingual Amazon Reviews Corpus (MARC) is a large collection of Amazon reviews [ 110 ]. The corpus contains reviews written in Chinese, English, Japanese, German, French, and Spanish. Each review is assigned a maximum of five stars. Each record contains the review text, the title, the star rating, and product-related metadata.
  • Polish: The Wroclaw Corpus of Consumer Reviews Sentiment [ 77 ] is a multi-domain dataset of Polish reviews from the domains of schools, medicine, hotels, and products. The texts have been annotated at both the sentence level and the text body level. The reviews are labeled as follows: [+m] represents a strong positive; [+s] represents a weak positive; [−m] represents a strong negative; [−s] represents a weak negative; [amb] represents ambiguity; and [0] represents neutrality.
  • Russian: The ROMIP-12 dataset [ 80 ] is composed of news-based opinions, which are excerpts of the direct and indirect speech published in news articles. Politics, economics, sports, and the arts are just some of the diverse subject areas covered. This dataset contains speech classified as positive, neutral, or negative.
  • Slovak: The Review3 [ 111 ] is composed of customer evaluations of a variety of services. The dataset is categorized using the 1–3 and 1–5 scales.
  • Slovene: The Opinion corpus of Slovene web commentaries KKS 1.001 [ 90 ] includes web commentaries on various topics (business, politics, sports, etc.) from four Slovene web portals (RtvSlo, 24ur, Finance, and Reporter). Each instance within the dataset is tagged with one of the three labels (negative, neutral, or positive).

6. Methodology

  • Used directly to train the model. Here, the source language serves as the target language as well (like Bulgarian).
  • Combined with a single dataset from a distant language family (like English).
  • Combined with a single dataset from a different sub-branch of the same language family (like Russian, Polish, or Czech).
  • Merged with a number of low-resource language datasets (Croatian, Slovak, and Slovene).

6.1. Model Details

6.2. training.

  • Using only source-language data for fine-tuning. This is the conventional transfer learning setup performed by a source-language fine-tuning classifier. A zero-shot test is administered to the trained model using a test of the target language. We guided the training process using the target language’s validation set. We projected labels from a fine-grained class of 5 classes to a coarse-grained class of 3 classes due to the possibility that the target language dataset labels do not match the source language.
  • Fine-tuning with a single source and target language. We sampled training sets from multiple languages and jointly trained the classifier. We utilized datasets from distantly related languages and vice versa.
  • Fine-tuning using multiple datasets derived from a single source and target language. This is a multilingual environment with multiple sources.
  • Fine-tuning with the Latin versions of the Bulgarian and Russian datasets.

Shopify: Valuation Does Not Match Fundamentals

Dair Sansyzbayev profile picture

  • Shopify's fundamentals are quite strong, with impressive revenue growth, operating leverage, and a fortress balance sheet.
  • However, even considering all the company's fundamental strengths and growth potential, the current valuation is too generous, with a 44% premium over the fair value.
  • Moreover, Wall Street analysts' sentiment regarding the upcoming Q2 earnings release is quite bearish, with more than twenty downward EPS revisions.

Investment thesis

My previous cautious thesis about Shopify ( NYSE: SHOP ) aged well, as the stock is significantly underperforming compared to the broader market since November 2023. More than six months passed since my previous coverage and today I want to share my updated analysis of Shopify.

Shopify remains fundamentally robust with strong revenue growth momentum, operating leverage, and a fortress balance sheet. The management works hard on improving the ecosystem, which is another long-term bullish sign. However, my discounted cash flow analysis suggests that the stock is massively overvalued. Moreover, the recent history of Q2 consensus EPS downgrades suggests that the Wall Street sentiment is quite pessimistic. All in all, I reiterate my "Hold" rating for SHOP.

Recent developments

The latest quarterly earnings were released on May 8, when the company surpassed consensus estimates. Revenue grew by 23.4% YoY. The adjusted EPS expanded significantly, from $0.01 to $0.20.

SHOP latest earnings

Seeking Alpha

The EPS expansion was of high quality as the operating margin expanded from -10% to 7.4% YoY. On the other hand, a major part of expansion was achieved after cutting the R&D to revenue ratio from 30% to sub-18%. The free cash flow [FCF] less stock-based compensation [SBC] was quite modest at around $66. Nevertheless, it contributed to the company's balance sheet which is a fortress with $5 billion cash pile and much lower total debt levels.

SHOP BS

The upcoming earnings release is scheduled for July 26. The adjusted EPS is expected to remain flat sequentially despite a projected 8% QoQ revenue growth. On a YoY basis, revenue is expected to grow around 19%, and the adjusted EPS to expand from $0.14 to $0.20. Wall Street sentiment around the upcoming earnings release is quite pessimistic with 23 EPS downgrades over the last 90 days, which is a bearish sign.

SHOP's upcoming earnings release

The management continues working hard on improving Shopify's ecosystem. We see it from aggressive R&D spending, which is still high in absolute terms despite a YoY contraction in the R&D to revenue ratio. Apart from in-house developments, Shopify also expands its partnerships network. The recent partnership expansion with Avalara will help merchants to streamline their processes related to tax compliance.

Chart

Amid the current AI revolution Shopify also does not forget about these cutting-edge technologies. The company recently expanded access to its AI-powered tools, which will also highly likely add the appeal of its ecosystem. Features include the Sidekick assistant and image-generation tools, which will also help merchants in streamlining their operations.

On the other hand, the macro environment remains quite uncertain. The Fed is still not cutting rates and now the market expects only one cut in 2024, instead of three cuts which were expected just a few months ago. Moreover, I think that there is a real probability of the Fed not cutting rates at all in 2024. I think so because there are really no reasons to rush as the U.S. economy is still robust, the unemployment rate is still close historical lows, and the fight against inflation looks over. The Fed highly likely realizes that easing monetary policy can lead to a spike in energy prices, which can launch a new wave of inflation growth. Therefore, from the macro environment perspective, the stock's near-term prospects look quite cloudy.

Valuation update

The stock was almost flat over the last twelve months with a modest 2.6% price increase. YTD performance looks poor with a 17% share price decrease. Despite the share price plunge, SHOP's valuation ratios are still extremely high. Most of ratios are lower than historical averages, but still around 10 P/S ratio looks too generous, in my opinion.

SHOP valuation ratios

However, SHOP's valuation ratios might be misleading because the company is aggressively growing. Therefore, I must simulate the discounted cash flow [DCF] model, and I want to start with figuring out the company's cost of equity. I ignore cost of debt for the discount rate because SHOP's debt levels are insignificant compared to its market cap. The discount rate is calculated using the CAPM approach and all variables are easily available on the Internet. According to calculations, SHOP's cost of equity is 17.25%.

SHOP's cost of equity

Author's calculations

Consensus estimates project an 18% revenue CAGR, which I incorporate into my DCF model. The TTM FCF ex-SBC margin is 2.5%, which is my base year's assumption. I project a 150 basis points yearly expansion for the FCF margin because of the expected solid revenue growth.

SHOP DCF

My DCF simulation suggests that the business's fair value is around $47 billion, substantially lower than the current market capitalization. That said, the stock is significantly overvalued. I agree that a 17.25% discount rate might be too aggressive for SHOP. However, even with a soft 10% discount rate Shopify's valuation does not look justified.

SHOP DCF 2

To conclude, Shopify's valuation looks far from being called attractive. Even with a very soft discount rate and aggressive 18% revenue CAGR, the stock is still overvalued.

Risks to my cautious thesis

Shopify's fundamentals are strong as the company demonstrates solid revenue growth and operating leverage. It has ample liquidity to continue investing loads of money in innovation and marketing, which can help in increasing revenue and EPS faster than consensus estimates project. That said, should SHOP deliver a strong earnings surprise in July, there might be a massive rally.

Moreover, Shopify's performance is historically strong in July. The below bar chart from TrendSpider suggests that over the last nine years, July was positive in almost 90% of cases.

SHOP's seasonality

TrendSpider

As we saw in the valuation update, SHOP's beta is extremely high. This means that the stock is volatile, and this includes swings in both directions. The stock has a history of showing sudden spikes in its price, which also might make my thesis look not good.

Bottom line

To conclude, I reiterate my "Hold" rating for SHOP. I think that the valuation is not justified despite all the fundamental strengths of the company. I am not ready to pay such a premium for the company which competes directly with a monster like Amazon ( AMZN ). Moreover, Wall Street analysts' sentiment around July's earnings release is quite pessimistic.

Futurity after the End of History: Chronotopes of Contemporary German Literature, Film, and Music

Wagner, Nathaniel Ross

This dissertation deploys theories of spatiotemporal experience and organization, most prominently Mikhail Bakhtin’s “chronotope,” to set contemporary literature, film, and music into dialogue with theories of post-Wende social and political experiences and possibility that speak, with Francis Fukuyama, as the contemporary as the “End of History.” Where these interlocutors of Fukuyama generally affirm or intensify his view of the contemporary as a time where historical progress slows to a halt, historical memory recedes from view, and the conditions of subjecthood are rephrased from participation in a struggle for progress to mindless consumption and technocratic tinkering, I engage contemporary artwork to flesh out and ultimately peer beyond the boundaries of the real and the possible these social theories articulate. Through a series of close readings of German films, music albums, and novels published between 1995 and 2021, I examine how German authors, filmmakers, and musicians pursue depictions of the malaises of the End of History while also resolutely pointing to the fissures in liberal capitalist hegemony where history—its past and its future—again becomes visible. Mikhail Bakhtin’s notion of the chronotope, a text’s unified expression of space and time, is central to my method of analysis. In tracing the chronotopic contours of contemporary works of music, film, and literature, I argue, we—as readers, viewers, and listeners—are engaged to think and act alongside the forms and figures that populate the worlds their authors create. In doing so, we ultimately uncover forceful accusations, resolute alternatives, and even hopeful antidotes to the deficiencies of our present that help us both to soberly contemplate the implications the pessimistic formulations of contemporary theory have on our lives, communities, and futures but also to formulate possibilities for them that lie beyond their analytical purview.In a series of close readings of my literary, filmic, and musical primary texts, I engage theorists of the post-Cold War, post-Wende contemporary who write about the political order and social conditions emerging out of the triumph of neoliberalism and market capitalism over socialist, communist, and fascist alternatives. The dissertation begins by establishing a wide view of the contemporary, tracing in its first chapter chronotopic resonances of Hartmut Rosa’s “social acceleration” thesis—which locates the aimlessness and alienation of contemporary society within the accelerationist logic of market capitalist modes of production—across the full temporal arc of the contemporary. Pairing Christian Kracht’s Faserland (1995) with Fatma Aydemir's Ellbogen (2017), I argue that the futilities and frustrations of the modern subject, as foretold in Fukuyama’s “End of History” essay and fleshed out in Rosa’s writings on social acceleration, find resonance not only in the wealthy, educated, white protagonist of Faserland’s 1990s, but also in the impoverished, undereducated, Turkish-Kurdish protagonist of Ellbogen some twenty years later. What connects these two accounts across decades and differences in identities, I demonstrate, is not merely a shared sense of alienation and despair, but a shared, underlying chronotopic characterization of the contemporary. These commonalities appear, I demonstrate, when we connect Rosa’s “social acceleration” thesis to diegetic chronotopes of perpetual motion that depict modern subjects’ inability to avail themselves of the ostensibly liberatory potential of liberal capitalism’s accelerated lifeworld. Chapter 2 then considers Byung-Chul Han’s theory of auto-exploitation and the dilemma of the music novel at a time where the rebellion of punk against social integration has been thoroughly incorporated into capitalism. Reading Marc Degens’ Fuckin Sushi (2015), I examine the novel’s concept of “Abrentnern” as a model for personal and communal fulfillment for those who turn to art as a means self-determination in the age of auto-exploitation. Unlike Kracht and Aydemir, however, Degens sees the closing off of historical possibilities for the good life enjoyed by his punk forbears—here, self-determination through transgressive artistic praxis—not as the contemporary subject’s damnation to cyclical patterns of despair but as a challenge to conceive of the good life anew. Working humorously through its hapless protagonist Niels’ repeated attempts to escape the seemingly inevitable for-profit co-option of his sincere artistic efforts, the novel serves to unveil the persistence of blind spots in this regime of totalizing exploitation. What results is an account of the double-edged logic of capitalist productivity’s ostensible totalization of labor-time. Capitalism, Niels unwittingly discovers, is a logic of production so overwhelming that it continuously drives subjects towards the discovery of new alterities that, for a brief time at least, allow subjects once again to slip between the cracks. The third chapter explores a similar phenomenon of halting resistance to the conditions of the capitalist present through the lens of futurity. Here, I push back against Mark Fisher’s theory of the dominance of “Capitalist Realism” in the contemporary aesthetic imagination, identifying and developing the notion of “subtle futurity”—the modest, yet resolute rephrasing of future possibility beyond the “way things are” of the present—in Leif Randt’s Schimmernder Dunst über CobyCounty (2011) In this light, I argue, Randt’s gestures towards a different future, however halting, mark a significant effort to imagine a benevolent form of future possibility within the context of an era often suspected to have been exhausted of its utopian sentiment. The final two chapters turn to past-minded works that more forcefully repudiate notions of the present as static or closed off from the movement of history. Chapter Four considers W.G. Sebald’s 1995 novel, Die Ringe des Saturn, and The Caretaker’s 2012 album, Patience (After Sebald), developing an account of the chronotopic means by which these works revisit materials of the past within the present. Chronotopic motifs of paraphrase—techniques of sampling in The Caretaker and narrative polyphony in Sebald—come together within macro-level chronotopic frameworks of peripatetic movement—looping repetition in The Caretaker and the retracing of bygone journeys in Sebald—to testify to the unanswered questions and unfinished work of history over and against notions of the present as a time where the past has been relegated to mere museum content or nostalgia for bygone ways of living. Where Chapter Four speaks primarily to the formal mechanisms by which the present rediscovers the past, Chapter Five examines two specific chronotopic innovations for thematically engaging constellations of past-present inter-temporality. Both Sharon Dodua Otoo’s 2021 novel, Adas Raum, and Christian Petzold’s 2018 film, Transit, develop chronotopes wherein past and present are intermingled in increasingly inseparable ways. Adas Raum, I demonstrate, is organized spatiotemporally as a nexus of coiled loops—pasts and presents intertwine, heaven and earth are tangled together, and the fates of human beings and even non-human objects follow spatial and temporal trajectories that weave in and out of conventional linear understandings of space and time. In similar fashion, past and present become inseparable in Petzold’s film, an adaptation of the Anna Seghers’ 1944 novel of the same name, through thematic and formal approaches of blurring that blend the plight of refugees of Seghers’ era with those of Petzold’s present day. History, then, appears remarkably robust in these texts, unfolding accounts of how human beings living through their present might take guidance from the generations that preceded them in the struggle for a better world.
