Analysis of mixed natural and symbolic language input in mathematical dialogs

Magdalena Wolska, Ivana Kruijff-Korbayová
2004 Proceedings of the 42nd Annual Meeting on Association for Computational Linguistics - ACL '04  
Discourse in formal domains, such as mathematics, is characterized by a mixture of telegraphic natural language and embedded (semi-)formal symbolic mathematical expressions.  ...  We present language phenomena observed in a corpus of dialogs with a simulated tutorial system for proving theorems as evidence for the need for deep syntactic and semantic analysis.  ...  However, little is known about the use of natural language in dialog setting in formal domains, such as mathematics, due to the lack of empirical data.  ...

Verification of human-level proof steps in mathematics education

Dominik Dietrich, Mark Buckley
2008 Teaching Mathematics and Computer Science  
Automated mathematics tutorial systems need support from a reasoning module which can verify the correctness of students' contributions.  ...  We present a domain-independent method for automatically verifying correct proof steps and detecting standard reasoning errors.  ...  Tutorial dialogue on mathematical proofs The framework in which our research is being carried out is the Dialog project [5] , which has the final goal of natural tutorial dialogue between a student and  ...

Towards an Intelligent Tutor for Mathematical Proofs

Serge Autexier, Dominik Dietrich, Marvin Schiller
2012 Electronic Proceedings in Theoretical Computer Science  
Our approach is motivated by phenomena found in a corpus of tutorial dialogs that were collected in a Wizard-of-Oz experiment.  ...  The resulting prototype was successfully evaluated on a corpus of tutorial dialogs and yields good results.  ...  The data was collected in an experiment where thirty-seven students interacted with a mock-up of a natural language dialog tutoring system for mathematical proofs.  ...

Proof step analysis for proof tutoring - a learning approach to granularity

Marvin Schiller, Dominik Dietrich, Christoph Benzmüller
2008 Teaching Mathematics and Computer Science  
The task of this module is to evaluate proof steps as typically uttered by students in tutoring sessions on mathematical proofs.  ...  We present a proof step diagnosis module based on the mathematical assistant system Ωmega.  ...  Acknowledgements We would like to thank Bruce McLaren for his input and comments on initial drafts of this paper. We thank an anonymous referee for helpful comments.  ...

A Systematic Literature Review of Intelligent Tutoring Systems with Dialogue in Natural Language

Jose Paladines, Jaime Ramirez
2020 IEEE Access  
Dialog interprets a mixture of natural language and mathematical expressions through a domain reasoner that requires deep syntactic and semantic analysis to obtain a formal representation of the steps  ...  To detect these misconceptions, the system relies on a domain reasoner that evaluates the soundness, granularity (acceptable size of the proof) and relevance (useful with respect to the goal) of the proof  ...

Argumentation in Explanations to Logical Problems [chapter]

Armin Fiedler, Helmut Horacek
2001 Lecture Notes in Computer Science  
Explaining solutions to logical problems is one of the areas where argumentation in natural language plays a prominent role.  ...  One crucial reason for the difficulty in pursuing this issue in a systematic manner when relying on formal inference systems lies in the discrepancy between machine-oriented reasoning and human-adequate  ...  Second, the transformed proof is verbalized in natural language.  ...

Moreover, it naturally decomposes the global and complex reasoning and truth maintenance task into local reasoning and truth maintenance tasks inside the system components.  ...  Mathematical assistance systems and proof assistance systems in general have traditionally been developed as large, monolithic systems which are often hard to maintain and extend.  ...  Ωmega is furthermore exploited as a domain reasoner in the proof tutoring environment Dialog [8] .  ...
