Strengthening semantic and orthographic associations among words in a lexicon may help to improve memory processes related to fluent organizing and retrieval of language. In the present study, we examined how training in several different word games impacts later retrieval access for the words. Games included a word-stem completion task (orthographic), a free association task (semantic), and a ...

Exploiting lexical and semantic relationships in text can dramatically improve information retrieval accuracy. Most notably, named entities and relations between entities are crucial for effective question answering and other information retrieval tasks. Unfortunately, the success in extracting these relationships can vary for different domains and document collections. Predicting extraction pe...

The University of Chicago participated in the Cross-Language Evaluation Forum 2004 (CLEF2004) cross-language multilingual, bilingual, and spoken language tracks. Cross-language experiments focused on meeting the challenges of new languages with freely available resources. We found that modest e ectiveness could be achieved with the additional application of pseudo-relevance feedback to overcome...

Naming a picture of a dog primes the subsequent naming of a picture of a dog (repetition priming) and interferes with the subsequent naming of a picture of a cat (semantic interference). Behavioral studies suggest that these effects derive from persistent changes in the way that words are activated and selected for production, and some have claimed that the findings are only understandable by p...

This paper describes experiments for testing the power of large-scale resources for lexical selection in machine translation (MT) and cross-language information retrieval (CLIR). We adopt the view that verbs with similar argument structure share certain meaning components , but that those meaning components are more relevant to argument realization than to idiosyncratic verb meaning. We verify ...

Today research data and output from nearly every disciplinary and interdisciplinary domain exist also (and sometimes only) in digital form. Consequently, to ensure the data’s efficient retrieval as well as long term usage and relevance, Knowledge Organisation and its tools/systems, i.e. lexical resources like thesauri and ontologies, play a major role in the Digital Libraries world. In this pap...

Bridging the lexical gap between the user’s question and the question-answer pairs in the Q&A archives has been a major challenge for Q&A retrieval. State-of-the-art approaches address this issue by implicitly expanding the queries with additional words using statistical translation models. While useful, the effectiveness of these models is highly dependant on the availability of quality corpus...

Background The purpose of the study was to analyze naming errors in patients with Alz-heimer's disease in comparison to healthy subjects and determine the underlying cause of naming errors in these patients. Method In this study, we included 35 healthy elderly subjects, 23 patients with mild Alzheimer's disease, and 23 with moderate Alzheimer's disease. Forty-five images were used to determin...
