Category: Analysis

This general research goal refers to the activity of extracting any kind of information from open or closed, structured or unstructured collections of data, of discovering recurring phenomena, units, elements, patterns, groupings, and the like. This can refer to structural, formal or semantic aspects of data. Analysis also includes methods used to visualize results. Methods and techniques related to this goal may be considered to follow Capture and Enrichment; however, Enrichment depends upon assumptions, research questions and results related to Analysis.

Met-Hodos: (Re)considering the road of research and analysis

Introduction: This blog, curated by Andreas W. Müller from Halle University, provides an insight on qualitative data analysis (QDA) techniques to conduct research in the field of Digital Humanities. The field is currently dominated by quantitative research methods, and is still lacking digital analysis derived from qualitative approaches. The author implies that QDA is a not a method, but a set of techniques that can be used with different analysis methods, for instance Content Analysis or Discourse Analysis. He also outlines how QDA deals with qualitative data combined with qualitative analysis, being both elements fundamental.

Automatic annotation of incomplete and scattered bibliographical references in Digital Humanities papers

Automatic annotation of incomplete and scattered bibliographical references in Digital Humanities papers

The reviewed article presents the project BILBO and illustrates the application of several appropriate machine-learning techniques to the constitution of proper reference corpora and the construction of efficient annotation models. In this way, solutions are proposed for the problem of extracting and processing useful information from bibliographic references in digital documentation whatever their bibliographic styles are. It proves the usefulness and high degree of accuracy of CRF techniques, which involve finding the most effective set of features (including three types of features: input, local and global features) of a given corpus of well-structured bibliographical data (with labels such as surname, forename or title). Moreover, this approach has not only been proven efficient when applied to such traditional, well-structured bibliographical data sets, but it also originally contributes to the processing of more complicated, less-structured references such as the ones contained in footnotes by applying SVM with new features for sequence classification.

RAWGraphs: A Visualization Platform to Create Open Outputs

RAWGraphs: A Visualization Platform to Create Open Outputs

The paper illustrates the features of the innovative tool in the field of data visualization: it is the framework RAW Graphs, available in an open access format at the website https://rawgraphs.io/. The framework permits to establish a connection between data coming from various applications (from Microsoft Excel to Google Spreadsheets) and their visualization in several layouts.

As detailed in the video guide available in the ‘Learning section’ (https://rawgraphs.io/learning), it is possible to load own data through a simple ‘copy and past’ command, and then select a chart-based layout among those provided: contour plot, beeswarm plot, hexagonal binnings, scatterplot, treemap, bump chart, Gantt chart, multiple pie charts, alluvial diagram and barchart. The platform permits also to unstack data according to a wide and a narrow format.

RAWGraphs, ideal for those working in the field of design but not only, is kept as an open-source resource thanks to an Indiegogo crowdfunding campaign (https://rawgraphs.io/blog).

Navegación de corpus a través de anotaciones lingüísticas automáticas obtenidas por Procesamiento del Lenguaje Natural: de anecdótico a ecdótico

Navegación de corpus a través de anotaciones lingüísticas automáticas obtenidas por Procesamiento del Lenguaje Natural: de anecdótico a ecdótico

Introduction: Spanish scholars Pablo Ruiz Fabo and Helena Bermúdez Sabel work in this article on two case studies regarding the application of Natural Language Processing (NLP) technologies, entity linking, and Computational Linguistics methods to create corpus navigation interfaces. The authors also focus on how these technologies for automatic text analysis allow us to enrich scholarly digital editions. They include interesting points of view about analogue and digital editions, and their relation with ecdotic practice.

Diseño de corpus literario para análisis cuantitativos

Diseño de corpus literario para análisis cuantitativos

Introduction: In this article, José Calvo Tello offers a methodological guide on data curation for creating literary corpus for quantitative analysis. This brief tutorial covers all stages of the curation and creation process and guides the reader towards practical cases from Hispanic literature. The author deals with every single step in the creation of a literary corpus for quantitative analysis: from digitization, metadata, automatic processes for cleaning and mining the texts, to licenses, publishing and achiving/long term preservation.

A World of Possibilities: a corpus-based approach to the diachrony of modality in Latin

A World of Possibilities: a corpus-based approach to the diachrony of modality in Latin

Introduction: Hosted at the University of Lausanne, “A world of possibilities. Modal pathways over an extra-long period of time: the diachrony in the Latin language” (WoPoss) is a project under development exploiting a corpus-based approach to the study and reconstruction of the diachrony of modality in Latin.
Following specific annotation guidelines applied to a set of various texts pertaining to the time span between 3rd century BCE and 7th century CE, the work team lead by Francesca Dell’Oro aims at analyzing the patterns of modality in the Latin language through a close consideration of lexical markers.

Pipelines for languages: not only Latin! The Italian NLP Tool (Tint)

Pipelines for languages: not only Latin! The Italian NLP Tool (Tint)

The StandforCore NLP wishes to represent a complete Java-based set of tools for various aspects of language analysis, from annotation to dependency parsing, from lemmatization
to coreference resolution. It thus provides a range of tools which
can be potentially applied to other languages apart from English.

Among the languages to which the StandfordCore NLP is mainly applied there is Italian, for which the Tint pipeline has been developed as described in the paper “Italy goes to Stanford: a collection of CoreNLP modules for Italian” by Alessio Palmero Apostolo and Giovanni Moretti.

On the Tint webpage the whole pipeline can be found and downloaded: it comprises tokenization and sentence splitting, morphological analysis and lemmatization, part-of-speech tagging, named-entity recognition and dependency parsing, including wrappers under construction.

Narrelations — Visualizing Narrative Levels and their Correlations with Temporal Phenomena

Narrelations — Visualizing Narrative Levels and their Correlations with Temporal Phenomena

Introduction: Introduction by OpenMethods Editor (Christopher Nunn): Information visualizations are helpful in detecting patterns in large amounts of text and are often used to illustrate complex relationships. Not only can they show descriptive phenomena that could be revealed in other ways, albeit slower and more laborious, but they can also heuristically generate new knowledge. The authors of this article did just that. The focus here is, fortunately, on narratological approaches that have so far hardly been combined with digital text analyzes, but which are ideally suited for them. To eight German novellas a variety of interactive visualizations were created, all of which show: The combination of digital methods with narratological interest can provide great returns to Literary Studies work. After reading this article, it pays to think ahead in this field.

Analyzing Documents with TF-IDF | Programming Historian

Analyzing Documents with TF-IDF | Programming Historian

Introduction: The indispensable Programming Historian comes with an introduction to Term Frequency – Inverse Document Frequency (tf-idf) provided by Matthew J. Lavin. The procedure, concerned with specificity of terms in a document, has its origins in information retrieval, but can be applied as an exploratory tool, finding textual similarity, or as a pre-processing tool for machine learning. It is therefore not only useful for textual scholars, but also for historians working with large collections of text.
