title = {Mining semantics for culturomics: towards a knowledge-based approach},
abstract = {The massive amounts of text data made available through the Google Books digitization project have inspired a new field of big-data textual research. 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.},

title = {Annotation of interpersonal relations in Swedish prose fiction.},
abstract = {This paper describes the manual annotation of a small sample of Swedish 19th and 20th century prose fiction with interpersonal relations between characters in six literary works. 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 = {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.},

@inProceedings{kokkinakis-2013-figurative-168227,
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.

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.},

title = {Fingerprint Matrices: Uncovering the dynamics of social networks in prose literature},
abstract = {In prose literature often complex dynamics of interpersonal relationships can be observed between the different characters. Traditionally, node-link diagrams are used to depict the social network of a novel. 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. A case study exemplifies the usage of Fingerprint Matrices and shows that they are an effective means to analyze prose literature with respect to the development of relationships between the different characters.},
