title = {Mining Fine-grained Opinion Expressions with Shallow Parsing},
abstract = {Opinion analysis deals with public opinions and trends, but subjective language
is highly ambiguous. In this paper, we
follow a simple data-driven technique to
learn fine-grained opinions. We select
an intersection set of Wall Street Journal documents that is included both in the
Penn Discourse Tree Bank (PDTB) and in
the Multi-Perspective Question Answering (MPQA) corpus. This is done in order to explore the usefulness of discourse-level structure to facilitate the extraction
of fine-grained opinion expressions. Here
we perform shallow parsing of MPQA expressions with connective based discourse
structure, and then also with Named Entities (NE) and some syntax features using
conditional random fields; the latter feature set is basically a collection of NEs and
a bundle of features that is proved to be
useful in a shallow discourse parsing task.
We found that both of the feature-sets are
useful to improve our baseline at different
levels of this fine-grained opinion expression mining task.},

title = {Relational Features in Fine-grained Opinion Analysis},
abstract = {Fine-grained opinion analysis often makes use of linguistic features but typically does not
take the interaction between opinions into account. This article describes a set of experiments that demonstrate that relational features, mainly derived from dependency-syntactic and semantic role structures, can significantly improve the performance of automatic systems for a number of fine-grained opinion analysis tasks: marking up opinion expressions, finding opinion holders, and determining the polarities of opinion expressions. These features make it possible to model the way opinions expressed in natural-language discourse interact in a sentence over arbitrary distances. The use of relations requires us to consider multiple opinions simultaneously, which makes exact inference intractable. However, a reranker can be used as a sufficiently accurate and efficient approximation.
A number of feature sets and machine learning approaches for the rerankers are evaluated. For the task of opinion expression extraction, the best model shows a 10-point absolute improvement in soft recall on the MPQA corpus over a conventional sequence labeler based on local contextual features, while precision decreases only slightly. Significant improvements are also seen for the extended tasks where holders and polarities are considered: 10 and 7 points in recall, respectively. In addition, the systems outperform previously published results for unlabeled (6 F-measure points) and polarity-labeled (10–15 points) opinion expression extraction. Finally, as an extrinsic evaluation, the extracted MPQA-style opinion expressions are used in practical opinion mining tasks. In all scenarios considered, the machine learning features derived from the opinion expressions lead to statistically significant improvement.},

abstract = {We consider the problem of training a statistical parser in the
situation when there are multiple treebanks available, and these
treebanks are annotated according to different linguistic
conventions.
To address this problem, we present two simple adaptation methods:
the first method is based on the idea of using a shared feature
representation when parsing multiple treebanks, and the second method
on guided parsing where the output of one parser provides features
for a second one.
To evaluate and analyze the adaptation methods, we train parsers
on treebank pairs in four languages: German, Swedish, Italian, and English.
We see significant improvements for all eight treebanks when training
on the full training sets. However, the clearest benefits are seen when we
consider smaller training sets. Our experiments were carried out with
unlabeled dependency parsers, but the methods can easily be
generalized to other feature-based parsers.},

Most of the component resources making up SweFN++ are existing digital lexical resources; in their case the central project effort is directed at making them interoperable on as many levels as possible. An important new resource being created in the project is a Swedish framenet. Now a sister project is starting with the aim of adding a Swedish constructicon (SweCxn) to the macro-resource. In this paper, we discuss some theoretical and conceptual issues which have arisen in the course of our work on the SweFN++ and the planning of the SweCxn, in the close encounter between the practical requirements of NLP and the theory and practice of linguistic – lexical and grammatical – description.

abstract = {Brain responses to familiar and unfamiliar voices were investigated with ERPs (Event Related Potentials). Presentation of a stream of one syllable utterances from a female voice established a standard expectation, and similar samples from four other male voices where inserted as unexpected deviants in a typical mismatch paradigm. The participants were 12 students from the basic course in linguistics. Two of the deviant voices were familiar voices of their teachers. The two other deviant voices were matched (same age, sex and dialect) but unfamiliar to the participants. A typical MMN (Mismatch Negativity) was elicited, i.e. a more negative response to the deviants compared to the standards. In contrast to verbal reports, where only one participant identified any of the deviant voices, the MMN response differed on group level between familiar and unfamiliar voices. MMN to familiar voices was larger. Using teachers' voices ensured naturalistic long term exposure, but did not allow for random assignment to conditions of familiarity making the design quasi-experimental. Thus acoustic analysis of voice characteristics as well as follow up studies with randomized exposure to voices are needed to rule out possible confounds and establish a causal effect of voice familiarity.},

The rank is then refined using Support Vector Machines and tree kernels applied to a structural representation of hypotheses, i.e., a hierarchy tree in which the outcome of binary one-vs-all classifiers is directly marked in its nodes. Our extensive experiments on the whole Reuters Corpus Volume 1 show that our models significantly improve over the state of the art in TC, thanks to the use of structural dependecies.},

title = {Between Grammars and Dictionaries: a Swedish Constructicon },
abstract = {This paper introduces the Swedish Constructicon (SweCxn), a database of Swedish constructions currently under development. We also present a small study of the treatment of constructions in Swedish (paper) dictionaries, thus illustrating the need for a constructionist approach, and discuss three different methods used to identify potential constructions for inclusion in the constructicon. SweCxn is a freely available electronic resource, with a particular focus on semi-general linguistic patterns of the type that are difficult to account for from a purely lexicographic or a purely grammatical perspective, and which therefore have tended to be neglected in both dictionaries and grammars. Far from being a small set of borderline cases, such constructions are both numerous and common. They are also quite problematic for second language acquisition as well as LT applications. Accordingly, various kinds of multi-word units have received more attention in recent years, not least from a lexicographic perspective. The coverage, however, is only partial, and the productivity of many constructions is hard to capture from a lexical viewpoint. To identify constructions for SweCxn, we use a combination of methods, such as working from existing construction descriptions for Swedish and other languages, applying LT tools to discover recurring patterns in texts, and extrapolating constructional information from dictionaries.

Named culturomics, this field has attracted the attention of a growing number of scholars over recent years. However, initial studies based on these data have been criticized for not referring to relevant work in linguistics and language technology. This paper provides some ideas, thoughts and first steps towards a new culturomics initiative, based this time on Swedish data, which pursues a more knowledge-based approach than previous work in this emerging field. The amount of new Swedish text produced daily and older texts being digitized in cultural heritage projects grows at an accelerating rate. These volumes of text being available in digital form have grown far beyond the capacity of human readers, leaving automated semantic processing of the texts as the only realistic option for accessing and using the information contained in them. The aim of our recently initiated research program is to advance the state of the art in language technology resources and methods for semantic processing of Big Swedish text and focus on the theoretical and methodological advancement of the state of the art in extracting and correlating information from large volumes of Swedish text using a combination of knowledge-based and statistical methods.},

However, static graphs can only visualize the overall social network structure but not the development of the networks over the course of the story, while dynamic graphs have the serious problem that there are many sudden changes between different portions of the overall social network. In this paper we explore means to show the relationships between the characters of a plot and at the same time their development over the course of a novel. Based on a careful exploration of the design space, we suggest a new visualization technique called Fingerprint Matrices.

An interpersonal relationship is an association between two or more people that may range in duration from brief to enduring. The annotation is guided by a named entity recognition step. Our goal is to get an in-depth understanding of the difficulties of such a task and elaborate a model that can be applied for similar annotation on a larger scale, both manually as well as automatically. The identification of interpersonal relations can, hopefully, aid the reader of a Swedish literary work to better understand its content and plot, and get a bird’s eye view on the landscape of the core story. Our aim is to use such annotations in a hybrid context, i.e., using machine learning and rule-based methods, which, in conjunction with named entity recognition, can provide the necessary infrastructure for creating detailed biographical sketches and extracting facts for various named entities which can be exploited in various possible ways by Natural Language Processing (NLP) technologies such as summarization, question answering, as well as visual analytic techniques.},

title = {Figurative Language in Swedish Clinical Texts. Potsdam, Germany},
abstract = {Automated processing of clinical texts with the intention to link all important text fragments to various established terminologies and ontologies for relation or event extraction is commonly faced with various less exposed, and not so regularly discussed linguistically motivated issues that needs to be addressed. One of these issues is the usage of figurative language. Figurative language, that is the use of words that go beyond their ordinary meaning, is not only a linguistically complex and challenging problem but also a problem that causes great difficulty for the field of natural language processing (NLP), both for the processing of general language and of various sublanguages, such as clinical medicine. Therefore, a comprehensive model of e.g. clinical language processing needs to account for figurative language usage and this paper provides a description towards this goal. Since the empirical, clinical data used in the study is limited in size, there is no formal distinction made between different sub-classifications of figurative language. e.g., metaphors, idioms or simile. As a matter of fact, all these types of expressions form a continuum with fuzzy boundaries, and most of the NLP-oriented approaches discussed in the past have used either very large data for the analysis or hand annotates samples, a situation that has been prohibitive so far in our project. Therefore distinction is solely based on a more general level, namely between literal versus figurative language, and on a more quantitative and corpus-based level, supported with concrete examples that illustrate several types of figurative expressions in the clinical discourse. The main research questions that this paper asks are whether there are traces of figurative language (or at least a subset of such types) in patient doctor and patient nurse interactions, how can they be found in a convenient way and whether these are transferred in the electronic health records and to what degree.

title = {A Macroanalytic View of Swedish Literature using Topic Modeling.},
abstract = {New research opportunities are plentiful for digital and literature scholars who are currently faced with increasingly large portions of large digitized archives produced during the last decades. Conventional methods of analysis involving a so called close reading view are not enough. Distant reading or macroanalysis is proposed instead, as a better, viable and more pragmatic alternative to the traditional methods of analyzing e.g., literature. According to this view, understanding literature is not accomplished by studying individual texts, but by aggregating and analyzing massive amounts of data. Therefore, applying macroanalytic methods and technologies is a priority among many research groups in the humanities worldwide. In this paper we explore topic modeling, an increasingly popular statistical method used for uncovering themes, topics and patterns in large amounts of text. We use available topic modeling software and, as empirical data, the content of the Swedish literature bank, a constantly growing body of Swedish fiction corpus from the 18th and 19th century. We present preliminary results on a sample of this corpus and discuss how humanistic research can be conducted through this type of computation, as a means to identify potential issues of interest e.g., for historians.},

abstract = {Extraction of information related to the medication is an im-portant task within the biomedical area. While the elaboration and updating of the drug vocabularies cannot follow the rap-id evolution of the drug development, we propose an automat-ic method for the extraction of known and new drug names. Our method combines internal and contextual clues. The method is applied to different types of documents in three languages (Swedish, French and English). The results indi-cate that with this kind of approach, we can efficiently update and enrich the existing drug vocabularies (probably with rap-id manual browsing). Precision and recall scores varied be-tween 81%-91% for precision and 85%-100% for recall. As a future work we intend to continuously refine the approach, by for instance better integration of semantic patterns and fuzzy matching that should hopefully enable further increase of the obtained results.},

abstract = {Abstract. The aim of this paper is to present some findings from a study into how a large scale semantic resource, FrameNet, can be applied for event extraction in the (Swedish) biomedical domain. Combining lexical resources with domain specific knowledge provide a powerful modeling mechanism that can be utilized for event extraction and other advanced text mining-related activities. The results, from developing a rule-based approach, showed that only small discrepancies and omissions were found between the semantic descriptions, the corpus data examined and the domain-specific semantics provided by SNOMED CT (medical terminology), NPL (medicinal products) and various semi-automatically developed clue lists (e. g., domain-related abbreviations). Although the described experiment is only based on four different domain-specific frames, the methodology is extendable to the rest ones and there is much room for improvements, for instance by combining rule-based with machine learning techniques, and using more advanced syntactic representations.},

abstract = {In qualitative projects on ICALL (Intelligent Computer-Assisted Language Learning), research and development always go hand
in hand: development both depends upon the research results and dictates the research agenda. Likewise, in the development of the Swedish ICALL platform Lärka, the practical issues of development have dictated its research agenda. With NLP approaches, sooner or later, the necessity for reliable training data becomes unavoidable. At the moment Lärka's research agenda cannot be addressed without access to reliable training data, so-called “gold standard”. This paper
gives an overview of the current state of the Swedish ICALL platform development and related research agenda, and describes the first attempts to collect the reference corpus (“gold standard”) coming from course books
used in CEFR-based language teaching.},

A result tracker containing a total and correct answer score keeps track of the language learner’s performance. In order to analyse typical spelling errors and provide better feedback, misspellings are collected in a database. The usability of the spelling exercises, concerning the different linguistic levels and the quality of speech, has been evaluated through a

title = {Compiling a corpus of CEFR-related texts.},
abstract = {This paper reports on initial efforts to compile a corpus of course book texts used for teaching CEFR-based courses of Swedish to adult immigrants. The research agenda
behind compiling such a corpus comprises the study of normative “input” texts that can
reveal a number of facts about what is being taught in terms of explicit grammar, receptive vocabulary, text and sentence readability; as well as build insights into linguistic characteristics of normative texts which can help anticipate learner performance in terms of active vocabulary, grammatical competence, etc. in classroom and testing settings.
The CEFR “can-do” statements are known to offer flexibility in interpreting them for
different languages and target groups. However, they are nonspecific and therefore it is difficult to associate different kinds of competences and levels of accuracy learners need in order to perform the communicative tasks with the different CEFR levels. To address this problem a systematic study needs to be performed for each individual anguage, both for “input” normative texts and “output” learner-produced texts. In this project we take
the first step to collect and study normative texts for Swedish.
The article describes the process of corpus compilation, annotation scheme of CEFR-
relevant parameters, and methods proposed for text analysis, namely statistic and empiric methods, as well as techniques coming from computational linguistics/machine learning.
