Multilingual opinion mining
170 p.Cada día se genera gran cantidad de texto en diferentes medios online. Gran parte de ese texto contiene opiniones acerca de multitud de entidades, productos, servicios, etc. Dada la creciente necesidad de disponer de medios automatizados para analizar, procesar y explotar esa información, las técnicas de análisis de sentimiento han recibido gran cantidad de atención por parte de la industria y la comunidad científica durante la última década y media. No obstante, muchas de las técnicas empleadas suelen requerir de entrenamiento supervisado utilizando para ello ejemplos anotados manualmente, u otros recursos lingüísticos relacionados con un idioma o dominio de aplicación específicos. Esto limita la aplicación de este tipo de técnicas, ya que dicho recursos y ejemplos anotados no son sencillos de obtener. En esta tesis se explora una serie de métodos para realizar diversos análisis automáticos de texto en el marco del análisis de sentimiento, incluyendo la obtención automática de términos de un dominio, palabras que expresan opinión, polaridad del sentimiento de dichas palabras (positivas o negativas), etc. Finalmente se propone y se evalúa un método que combina representación continua de palabras (continuous word embeddings) y topic-modelling inspirado en la técnica de Latent Dirichlet Allocation (LDA), para obtener un sistema de análisis de sentimiento basado en aspectos (ABSA), que sólo necesita unas pocas palabras semilla para procesar textos de un idioma o dominio determinados. De este modo, la adaptación a otro idioma o dominio se reduce a la traducción de las palabras semilla correspondientes
Metaphor in social thought
Whereas a number of influences have directed the attention of sociologists and others towards language
as a feature of social phenomena, these same influences have served to reveal wide discrepancies in the
place accorded to figurative language, and to metaphor in particular. This has proved to be the case both
in respect of the phenomena studied and of the subsequent writing. These influences have included, inter
alia, 'the linguistic turn' in philosophy, the rise and fall of structuralism both as philosophy and as a
model for anthropology, and also in the development of ethnomethodology from phenomenology.
The thesis specifically locates the enquiry within the writer's biography and is not sited within anyone
traditional discipline, but has rather been a reading 'between literature and science' and one 'privileging'
metaphor over concept. The attempt to explore the 'privileging' of metaphor over concept renders
problematic an understanding of language as langue, and prefers parole. Rendering language problematic
has consequences for how knowledge and science are understood. In parallel with the reading, an
ethnomethodological study of a school was undertaken in order to provide a context in which the
outcomes of the reading could be sited and compared, leading to a consideration of metaphor within
ethnography.
With these starting assumptions, a report is made of a limited number of authors who have been widely
acknowledged as influential in considerations of metaphor. Aristotle is read, through and against recent
interpreters, as if an ontology of metaphor were considered undesirable. This leads to an understanding
of metaphor as a tool. Hobbes is seen through the work of Quentin Skinner as one who, influenced by his
contemporary Descartes, is critical of the use of metaphor in spite of his articulate use of it. Vico, not
widely influential until the late nineteenth and twentieth centuries, reveals a diachronic picture of the
primacy of metaphor in relation to the development of concepts, later supported by Herder who offered a
complementary, though synchronic, version. Nietzsche, writing in a post-Darwin context, sees the
formation of metaphor as the fundamental human drive and links it with truth as a value. Work on
metaphor during the latter parts of the twentieth century is described beginning with I. A. Richards,
leading to brief considerations, inter alia, of Max Black, W. V. O. Quine, Mary Hesse, Rom Harre and
Hayden White. Writers in the social sciences who have been explicit about the part played by metaphor,
Victor Turner, R. H. Brown, R. A. Nisbet and D. McCloskey are acknowledged. Donald Davidson is seen
as particularly influential, denying the possibility of a separate notion of metaphorical meaning and
confirming a denial of langue. Richard Rorty is seen as a writer who has treated metaphor positively in his
Contingency, Irony and Solidarity and his use of metaphor there is examined in its variety. Throughout, the
Nietzschean view of the formation of metaphor as the fundamental human drive is connected with
Cohen's view that metaphor cultivates intimacy. It is on this basis that the above writers, some of whom
would otherwise be seen as belonging to different genres, most prominently philosophy, have
contributed to social thought, and to the place of metaphor within it. The insight into metaphor as a
fundamental human drive and as cultivating intimacy is then linked with the view that metaphor
becomes valued as concept by virtue of the work done in linking past action to new circumstances. This
combination, one linking metaphor with pragmatism, is used as a pattern by which to inspect others'
writings. The widespread rejection or devaluation of metaphor in social theory could then be related to its
role having been undermined by the rhetoric of natural science, though freed somewhat by T. S. Kuhn, an
undermining which threatens creativity and the cultivation of intimacy with its implications for the
formation and sustaining of communities.
The supposition, for reasons of the production of social science, that once the analogies contained in or
suggested by a metaphor may thereafter be discarded, is resisted on the grounds that history is
overlooked, persons are no longer seen in relation, knowing and certainty work to bring play to an end,
learning is transformed from personal engagement to instruction, community is replaced by rules for
rational conduct, and obedience replaces discovery and growth. Metaphor explicitly identified offers
hope

Big Digital Humanities: Imagining a Meeting Place for the Humanities and the Digital
Big Digital Humanities has its origins in a series of seminal articles Patrik Svensson published in the Digital Humanities Quarterly between 2009 and 2012. As these articles were coming out, enthusiasm around Digital Humanities was acquiring a great deal of momentum and significant disagreement about what did or didn’t “count” as Digital Humanities work. Svensson’s articles provided a widely sought after omnibus of Digital Humanities history, practice, and theory. They were informative and knowledgeable and tended to foreground reportage and explanation rather than utopianism or territorial contentiousness. In revising his original work for book publication, Svensson has responded to both subsequent feedback and new developments. Svensson’s own unique perspective and special stake in the Digital Humanities conversation comes from his role as director of the HUMlab at Umeå University. HUMlab is a unique collaborative space and Digital Humanities center, which officially opened its doors in 2000. According to its own official description, the HUMlab is an open, creative studio environment where “students, researchers, artists, entrepreneurs and international guests come together to engage in dialogue, experiment with technology, take on challenges and move scholarship forward.” It is this last element “moving scholarship forward” that Svensson argues is the real opportunity in what he terms the “big digital humanities,” or digital humanities as practiced in collaborative spaces like the HUMlab, and he is uniquely positioned to take an account of this evolving dimension of Digital Humanities practice
Compositional language processing for multilingual sentiment analysis
Programa Oficial de Doutoramento en Computación. 5009V01[Abstract] This dissertation presents new approaches in the field of sentiment
analysis and polarity classification, oriented towards obtaining the sentiment
of a phrase, sentence or document from a natural language
processing point of view. It makes a special emphasis on methods
to handle semantic composionality, i. e. the ability to compound the
sentiment of multiword phrases, where the global sentiment might
be different or even opposite to the one coming from each of their
their individual components; and the application of these methods to
multilingual scenarios.
On the one hand, we introduce knowledge-based approaches to calculate
the semantic orientation at the sentence level, that can handle
different phenomena for the purpose at hand (e. g. negation, intensification
or adversative subordinate clauses).
On the other hand, we describe how to build machine learning
models to perform polarity classification from a different perspective,
combining linguistic (lexical, syntactic and semantic) knowledge,
with an emphasis in noisy and micro-texts.
Experiments on standard corpora and international evaluation campaigns
show the competitiveness of the methods here proposed, in
monolingual, multilingual and code-switching scenarios.
The contributions presented in the thesis have potential applications
in the era of the Web 2.0 and social media, such as being able to
determine what is the view of society about products, celebrities or
events, identify their strengths and weaknesses or monitor how these
opinions evolve over time. We also show how some of the proposed
models can be useful for other data analysis tasks.[Resumen] Esta tesis presenta nuevas técnicas en el ámbito del análisis del sentimiento
y la clasificación de polaridad, centradas en obtener el sentimiento
de una frase, oración o documento siguiendo enfoques basados en
procesamiento del lenguaje natural. En concreto, nos centramos en
desarrollar métodos capaces de manejar la semántica composicional,
es decir, con la capacidad de componer el sentimiento de oraciones
donde la polaridad global puede ser distinta, o incluso opuesta, de la
que se obtendría individualmente para cada uno de sus términos; y
cómo dichos métodos pueden ser aplicados en entornos multilingües.
En la primera parte de este trabajo, introducimos aproximaciones
basadas en conocimiento para calcular la orientación semántica a nivel
de oración, teniendo en cuenta construcciones lingüísticas relevantes
en el ámbito que nos ocupa (por ejemplo, la negación, intensificación,
o las oraciones subordinadas adversativas).
En la segunda parte, describimos cómo construir clasificadores de
polaridad basados en aprendizaje automático que combinan información
léxica, sintáctica y semántica; centrándonos en su aplicación sobre
textos cortos y de pobre calidad gramatical.
Los experimentos realizados sobre colecciones estándar y competiciones
de evaluación internacionales muestran la efectividad de los
métodos aquí propuestos en entornos monolingües, multilingües y
de code-switching.

Consent, Coercion, and Compassion: Emerging Legal Responses to the Commercial Sexual Exploitation of Minors
Elana was thirteen when her mother kicked her out of the house. As a result of her mother\u27s neglect, she landed in foster care in a group home run by the city. Frustrated by the fights and the bullying that she encountered at the group home, Elana often spent time on the streets. During this time, she met a man and woman who said that they would take care of her if she came to live with them. They said they would provide her with a comfortable home, nice clothes, and would help her make money. Elana was enticed by the promise of things that she did not have at home or in foster care and agreed to go with them
