Chapter
The paper gives a brief overview of the four shared tasks to be organized at the PAN 2022 lab on digital text forensics and stylometry hosted at the CLEF 2022 conference. The tasks include authorship verification across discourse types, multi-author writing style analysis, author profiling, and content profiling. Some of the tasks continue and adva...

Preprint
Both linguistic and arithmetic task characteristics contribute to the difficulty of a word problem. However, the role of these characteristics and the exact cognitive processes underlying arithmetic word problems are often not clear, but they might be detectable by analysing eye-movement patterns. Not much is known about how eye-movements change un...
Article
Full-text available
Performance on word problems is influenced by linguistic and arithmetic factors, and by their interaction. To study these factors and interactions, we manipulated linguistic and arithmetic factors independently in a within-participant design that included complexity parameters (a) in the domain of arithmetic: carry/borrow (no-carry/borrow vs. carry...

Automated scoring systems which evaluate content require robust ways of dealing with form errors. The work presented in this paper is set in the context of scoring learners' responses to listening comprehension items included in a placement test of German as a foreign language. Based on a corpus of over 3000 responses to 17 questions, by test taker...
Article
Full-text available
Word problems (WPs) belong to the most difficult and complex problem types that pupils encounter during their elementary-level mathematical development. In the classroom setting, they are often viewed as merely arithmetic tasks; however, recent research shows that a number of linguistic verbal components not directly related to arithmetic contribut...

Conference Paper
We present an extrinsic evaluation of a clustering-based approach to computer-assisted scoring of short constructed response items, as encountered in educational assessment. Due to their open-ended nature, constructed response items need to be graded by human readers, which makes the overall testing process costly and time-consuming. In this paper...
Conference Paper
Full-text available
This study presents the results of a large-scale comparison of various measures of pitch range and pitch variation in two Slavic (Bulgarian and Polish) and two Germanic (German and British English) languages. The productions of twenty-two speakers per language (eleven male and eleven female) in two different tasks (read passages and number sets) ar...
Thesis
http://universaar.uni-saarland.de/monographien/volltexte/2015/111/pdf/wolska_mathematicalProofs_komplett_e.pdf Truth and proof are central to mathematics. Proving (or disproving) seemingly simple statements often turns out to be one of the hardest mathematical tasks. Yet, doing proofs is rarely taught in the classroom. Studies on cognitive difficu...

A concept rater module is utilized to automatically grade or score constructed responses based on a model answer. The concept rater module may be configured to accept a model answer as input. The model answer may be used as a grading key by the concept rater module. The concept rater module may be further configured to accept student responses in a...
Conference Paper
Full-text available
A Bulgarian and a German sentence were presented to Bulgarian and German listeners together with a question which either ex¬pec¬¬ted an early narrow focus or a late narrow focus. The answering sentences were manipulated so that the word in the late-focused position ranged from completely de-accented to strongly accented. The early focused position...
Conference Paper
Full-text available
The paper reports on a comparative study of two approaches to extracting definitional sentences from a corpus of scholarly discourse: one based on bootstrapping lexico-syntactic patterns and another based on deep analysis. Computational Linguistics was used as the target domain and the ACL Anthology as the corpus. Definitional sentences extracted f...
Article
Full-text available
We describe a novel approach to precise searching in the full content of digital libraries. The Searchbench (for search workbench) is based on sentence-wise syntactic and semantic natural language processing (NLP) of both born-digital and scanned publications in PDF format. The term born-digital means natively digital, i.e. prepared electronically...
Conference Paper
Full-text available
We present a method for determining the context-dependent denotation of simple object-denoting mathematical expressions in mathematical documents. Our approach relies on estimating the similarity between the linguistic context within which the given expression occurs and a set of terms from a flat domain taxonomy of mathematical concepts; one of 7...
Conference Paper
Full-text available
We present a dialogue system for exercising the German subordinate clause word order. The pedagogical methodology we adopt is based on focused tasks: the targeted linguistic structure is embedded in a naturalistic scenario, “Making appointments”, in which the structure can be plausibly elicited. We report on the system we built and an experimental...
Chapter
Formal domains, such as mathematics, require exact language to communicate the intended content. Special symbolic notations are used to express the semantics precisely, compactly, and unambiguously. Mathematical textbooks offer plenty of examples of concise, accurate presentations. This effective communication is enabled by interleaved use of formu...
Conference Paper
We present three corpus-based studies on symbol declaration in mathematical writing. We focus on simple object denoting symbols which may be part of larger expressions. We look into whether the symbols are explicitly introduced into the discourse and whether the information on once interpreted symbols can be used to interpret structurally related s...
Conference Paper
We present a preliminary study on disambiguation of symbolic expressions in mathematical documents. We propose to use the natural language within which the expressions are embedded to resolve their semantics. The approach is based on establishing a similarity between the expression’s discourse context and a set of terms from Term Clusters based on...

Full-text available
In this paper we present a taxonomy of dialogue moves which describe the actions performed by participants in task-oriented dialogue. Our work is motivated by the need for a categorisation of such actions in order to develop computational models for tutorial dialogue. As such, we build on both existing work on dialogue move categorisation for the t...

In this paper we present a taxonomy of di- alogue moves which describe the actions that students and tutors perform in tutorial dialogue. We are motivated by the need for a categorisation of such actions in order to develop computational models for tutorial dialogue. As such, we build both on exist- ing work on dialogue move categorisation for tuto...
Article
Full-text available
We present a modular architecture for processing informal mathematical language as found in textbooks and mathematical publica- tions. We point at its properties relevant in addressing three aspects of informal mathematical discourse: (i) the interleaved symbolic and natu- ral language, (ii) the linguistic, domain, and notational context, and (iii)...
Article
Full-text available
Pedagogically motivated analyses of tutorial dialogue have identified recurring local se- quences of exchanges which we propose to be analysed analogously to grounding structures. In this paper, we present a model describing such local structures in which a learner and a tutor collaboratively contribute to building a solution to a task. Such struct...
Conference Paper
Teaching problem-solving in formal domains aims at two purposes: 1) increasing the students' skill in addressing the problem in a goal-oriented way, and 2) increasing their competence in expressing themselves formally. In a dialog, suitable tutoring strategies addressing both issues may be quite delicate, especially when meeting formally inaccurate...
Article
Full-text available
In order to avoid miscommunication par- ticipants in dialogue continuously attempt to align their mutual knowledge (the "common ground"). A setting that is per- haps most prone to misalignment is tu- toring. We propose a model of common ground in tutoring dialogues which explic- itly models the truth and falsity of do- main level contributions and...
Article
Dialogs in formal domains, such as mathematics, are characterized by a mixture of telegraphic natural language text and embedded formal expressions. Analysis methods for this kind of setting are rare and require empirical justification due to a notorious lack of data, as opposed to the richness of presentations found in genre-specific textbooks. In...
Conference Paper
In tutorial systems, effective progress in teaching the problem-solving target is frequently hindered by expressive sloppiness and low-level errors made by the student, especially in conventionalized expressions such as formulas. In order to improve the effectiveness of tutorial systems in teaching higher-level skills, we present a fault-tolerant f...
Conference Paper
Full-text available
We present DiaWOz-II, a configurable software environment for Wizard-of-Oz studies in mathematics and engineering. Its interface is based on a structuralwysiwyg editor which allows the input of com- plex mathematical formulae. This allows the collection of dialog corpora consisting of natural language interleaved with non-trivial mathemati- cal exp...
Conference Paper

Successful participation in dialogue as well as understanding written text requires, among others, interpretation of specifications implicitly conveyed through parallel structures. While those whose reconstruction requires insertion of a missing element, such as gapping and ellipsis, have been addressed to a certain extent by computational approach...

Conference Paper
Successful participation in task-oriented, inference-rich dialogs requires, among other things, understanding of specifications implicitly conveyed through the exploitation of parallel structures. Several linguistic operators create specifications of this kind, including “the other way (a)round”, “vice-versa”, and “analogously”; unfortunately, auto...
Conference Paper
Full-text available
Natural language interaction between a student and an assis-tance system for mathematics is a new multi-disciplinary challenge that requires the interaction of (i) advanced natural language processing, (ii) flexible tutorial dialog strategies including hints, and (iii) mathematical domain reasoning. Although each of these fields o ers substantial s...

Conference Paper
We present a fault-tolerant formula interpreter that aims at finding plausibly intended, formally correct specifications from student statements containing formal inaccuracies. Its methods comprise local changes based on error categories, fault-tolerant structure building, and testing contextually-motivated alternations.
Article
Full-text available
Until recently, rigid and sometimes cumber-some structures, which underly dialog pat-terns considered manageable for achieving a given task in a controlled manner, proved to be a serious weakness of interactive sys-tems. Through the introduction of the in-formation state as a representation to con-trol the evolving state of a dialog, substan-tial i...

Discourse in formal domains, such as mathe- matics, is characterized by a mixture of tele- graphic natural language and embedded formal expressions. Little is known about the suitabil- ity of input analysis methods for mathematical discourse in a dialog setting, due to the lack of empirical data. In this paper, we report on the development of a dep...
