With proliferation of user-generated reviews, new opportunities and challenges arise. The advance of Web technologies allows people to access a large amount of reviews of products and services online. Knowing what others like and dislike becomes increasingly important for their decision making in online shopping. The retailers also care more than ever about online reviews, because a vast pool of reviews enables them to monitor reputations and collect feedbacks efficiently. However, people often find difficult times in identifying and summarizing fine-grained sentiments buried in the opinion-rich resources. The traditional sentiment analysis, which focuses on the overall sentiments, fails to uncover the sentiments with regard to the aspects of the reviewed entities. This dissertation studied the research problem of Aspect Based Sentiment Analysis (ABSA), which is to reveal the aspect-dependent sentiment information of review text. ABSA consists of several subtasks: 1) aspect extraction, 2) aspect term extraction, 3) aspect category classification, and 4) sentiment polarity classification at aspect level. We focused on the approach of topic models and neural networks for ABSA. First, to extract the aspects from a collection of reviews and to detect the sentiment polarity regarding the aspects in each review, we proposed a few probabilistic graphical models, which can model words distribution in reviews and aspect ratings at the same time. Second, we presented a multi-task learning model based on long-short term memory and convolutional neural network for aspect category classification and aspect term extraction. Third, for aspect-level sentiment polarity classification, we developed a gated convolution neural network, which can be applied to aspect category sentiment analysis as well as aspect target sentiment analysis.

This project involves the retelling of a historic New Zealand story using a system of multiple narrations. The research is presented in three parts:1. The practical component, Last Man Hanging: a book of pictures.2. A contextualising exegesis.3. 31 months (a documentation of my visual journey). The major component of this research is the creative text, Last Man Hanging. This is a book of pictures and type that retells the story of the trial and death of Walter James Bolton; the last man hanged in New Zealand. Its narrative discourse involves the orchestration of relationships through a compendium of characters, architecture, artifacts, environments and typography. The book integrates narrative voices that may be grouped into two often-conflicting positions; the story as it appeared in newspapers at the time, and the writer's personal consideration of an alternative series of events and emphases. Though an argument of tellings the book suggests a different verdict to that established by the courts in 1956.Finally, the exegesis contextualises both works. It considers specific theoretical issues pertaining to Last Man Hanging's narrative voice and imagery.

Nucleic acid and protein databases such as GenBank are growing at a rate that perhaps eclipses even Moore’s Law of increase in computational power. This poses a problem for the biological sciences, which have become increasingly dependant on searching and manipulating these databases. It was once reasonably practical to perform exhaustive searches of these databases, for example using the algorithm described by Smith and Waterman, however it has been many years since this was the case. This has led to the development of a series of search algorithms, such as FASTA, BLAST and BLAT, that are each successively faster, but at similarly successive costs in terms of thoroughness. Attempts have been made to remedy this problem by devising search algorithms that are both fast and thorough. An example is CAFE, which seeks to construct a search system with a sub-linear relationship between search time and database size, and argues that this property must be present for any search system to be successful in the long term. This dissertation explores this notion by seeking to construct a search system that takes advantage of the growing redundancy in databases such as GenBank in order to reduce both the search time and the space required to store the databases and their indices, while preserving or increasing the thoroughness of the search. The result is the creation and implementation of new genomic sequence search and alignment, database compression, and index compression algorithms and systems that make progress toward resolving the problem of reducing search speed and space requirements while improving sensitivity. However, success is tempered by the need for databases with adequate local redundancy, and the computational cost of these algorithms when servicing un-batched queries.

In 'The Crypt, the Haunted House of Cinema', Cholodenko argues that film is, metaphorically speaking, a haunted house: an instance of the uncanny. This raises the possibility the film script is also uncanny, from the Freudian notion of das Unheimliche, the strangely familiar and familiarly strange - and thus also a haunted house. This proposition engenders a search as self-reflexive practice for that which haunts the script' an uncanny process to explore the uncanny. The search requires drawing on Barthes, acting 'as dead' with that process' attendant contradictions and problematics' the most likely ghost in the script being the writing self. Establishing the characteristics of the writing self involves distinguishing that figure from the author. This requires outlining the development of theories of the author from the concept of authorial will, as per the argument of Hirsch, to the abnegation of the author as a philosophical certainty. Barthes and Foucault call this abnegation the death of the author. Rather than that marking the end of a particular branch of analysis, the death of the author can be considered an opening to the writing practice. From this perspective, the death of the author becomes a strategy in Foucault's game of writing, effecting the obfuscation of the writing self, by placing a figure as dead, the author figure, within the metaphorical topography of the text. Indeed, the author as dead is akin to a character in the narrative but at a substratum level of the text. What places this dead figure within the text is an uncanny writing self, a figure of transgression, brought into being in the experience of Blanchot's essential solitude. 'The Seaborne' written by Matt Marshall, provides an example of a film script that constitutes a haunted house, a site of the uncanny. In terms of the generic characteristics of the film script as text type, its relative unimportance in relation to any subsequent film based on the script becomes of itself a feature of the film script. This makes the film script a site of negotiation and contestation between the implied author as hidden director on the one hand and the implied reader as implied director on the other. This confirms the film script as, using Sternberg's terminology, a blueprint text type. Examples of the negotiation and relationship between hidden director and implied director are found in analysis of 'The Seaborne' as are the tensions in the relationship between the individualistic impulses of the hidden director and the mechanistic, formal requirements of the text type as blueprint. These tensions are ameliorated by the hidden director who is then effaced within the constructed layers of the film script text to allow interpretive space for the implied director. 'The Seaborne' as representative of the film script text becomes the after-image of a written text and the foreshadowing of a future filmic one. It therefore never finds completion within its own construction process and its formation begins in templates that accord with the Bakhtin's description of the epic, as is shown by comparing the construction notes for 'The Seaborne' with Aristotlean dramatic requirements. But at the same time there is present in 'The Seaborne' a Bakhtinian dialogism that points towards the individual markers of a writing self. This writing self, referring to Kristeva, is a figure of abjection. It transgresses itself and transgresses its own transgressions. It is a ghost in a ghost story without ghosts.

Recent discussions of the state of Medieval Studies, sparked by such books as Lee Patterson’s Negotiating the Past, provide an important impetus for this thesis because they highlight the critical abyss which exists between Medieval Studies and other areas of literary studies. For one entering the field of Medieval Literary Studies this revelation is disturbing and inhibiting. However, the history of Medieval Studies cannot be ignored by those now working within the area. If Medieval Studies is to survive it must come to terms with its past and recognise the precarious position in which the discipline now stands as a result of its academic isolation. ...

<p>Hur skapar jag en kundtidning som stärker relationen mellan kund och företag? Det är problemställningen som legat till grund för det här examensarbetet.</p><p>Syftet med kundtidningen är att informera om energi och miljö, men även att skapa en god relation till kunden och kommunicera en känsla av samhörighet. Utifrån litteraturstudier har jag kommit fram till att detta kan uppnås genom att göra kunderna delaktiga i tidningens redaktionella innehåll och skapandet av det. Kunddelaktighet, kundnöjdhet och kundlojalitet är positivt relaterade till varandra. Företaget kan styra innehållet i den riktning det vill genom att behålla kontrollen över urvalet och på så sätt även uppnå sitt tilltänkta informativa syfte.</p><p>Delaktigheten kan ske i olika former och blir tydligast när kunder finns representerade i text och bild. Delaktigheten kan bland annat bygga på kundernas behov, intressen, åsikter och erfarenheter. Genom analyser har jag fått kunskap i hur delaktigheten kan gestalta sig. I undersökningar har jag vidare fått kännedom om kundernas behov och intressen.</p><p>Kundtidningen är en produkt som kommer att påverka kundens uppfattning om företaget och därmed även kundnöjdhet och lojalitet. Språket är anpassat för att motsvara de krav som samhället ställer på offentliga texter. Att kunna ta del av information är en demokratisk rättighet. Texterna är skrivna utifrån riktlinjerna för lättläst för att passa en så bred målgrupp som möjligt.</p>

There are numerous text documents available in electronic form. More and more are becoming available every day. Such documents represent a massive amount of information that is easily accessible. Seeking value in this huge collection requires organization; much of the work of organizing documents can be automated through text classification. The accuracy and our understanding of such systems greatly influences their usefulness. In this paper, we seek 1) to advance the understanding of commonly used text classification techniques, and 2) through that understanding, improve the tools that are available for text classification. We begin by clarifying the assumptions made in the derivation of Naive Bayes, noting basic properties and proposing ways for its extension and improvement. Next, we investigate the quality of Naive Bayes parameter estimates and their impact on classification. Our analysis leads to a theorem which gives an explanation for the improvements that can be found in multiclass classification with Naive Bayes using Error-Correcting Output Codes. We use experimental evidence on two commonly-used data sets to exhibit an application of the theorem. Finally, we show fundamental flaws in a commonly-used feature selection algorithm and develop a statistics-based framework for text feature selection. Greater understanding of Naive Bayes and the properties of text allows us to make better use of it in text classification.
