Extracting glossary sentences from scholarly articles: A comparative evaluation of pattern bootstrapping and deep analysis
TLDR
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 show that both methods extract high-quality definition sentences intended for automated glossary construction.

Word problems: a review of linguistic and numerical factors contributing to their difficulty
TLDR
This review discusses the impact of each of these factors on WP difficulty and motivate the need for a high degree of control in stimuli design for experiments that manipulate WP difficulty for a given age group. Expand
A Wizard of Oz Experiment for Tutorial Dialogues in Mathematics
In this paper we report on a Wizard-of-Oz (WOz) experiment which was conducted in order to collect written empirical data on mathematics tutorial dialogues in German. We present a methodologicalExpand
Description of the UPENN CAMP System as Used for Coreference
TLDR
A new coreference scoring algorithm is presented, the B-CUBED algorithm, which was designed to overcome the shortcomings of the MUC-6 algorithm. Expand
Finding a Tradeoff between Accuracy and Rater's Workload in Grading Clustered Short Answers
TLDR
This paper uses surface features like word and character n-grams to cluster answers to listening comprehension exercises per question and investigates various ways to select this single item to be labeled, finding that choosing the item closest to the centroid of a cluster leads to improved grading accuracy over random item selection.

Using Discourse Context to Interpret Object-Denoting Mathematical Expressions
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 similarityExpand
Tutorial dialogs on mathematical proofs
TLDR
This work identifies several interesting problems which lead to requirements for mathematical knowledge representation, including resolving reference between natural language expressions and mathematical formulas, and determining the contribution of inference steps specified by the user. Expand
Comparison of Pitch Range and Pitch Variation in Slavic and Germanic Languages
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)Expand
Toward evaluation of writing style: finding overly repetitive word use in student essays
TLDR
A system that evaluates a characteristic of lower quality essay writing style: repetitious word use is embedded in a commercial writing assessment application, CriterionSM, which uses a machine-learning approach with word-based features to model repetitiousword use in an essay. Expand
Towards context-based disambiguation of mathematical expressions
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 theirExpand
