Date: October 2008
Creator: Coursey, Kino High; Mihalcea, Rada & Moen, William E.
Description: Abstract: This paper describes experiments in metadata generation for learning object repositories. Specifically, the authors present several methods for automatic keyword extraction and evaluate them on a collection of learning objects from an undergraduate history course. The results suggest that automatic keyword extraction is a viable solution for suggesting terms and phrases for metadata annotation.

An Automatic Method for Generating Sense Tagged Corpora
Date: 1999
Creator: Mihalcea, Rada & Moldovan, Dan
Description: This paper discusses an automatic method for generating sense tagged corpora. Abstract: The unavailability of very large corpora with semantically disambiguated words is a major limitation in text processing research. For example, statistical methods for word sense disambiguation of free text are known to achieve high accuracy results when large corpora are available to develop context rules, to train and test them. This article presents a novel approach to automatically generate arbitrarily large corpora for word senses. The method is based on (1) the information provided in WordNet, used to formulate queries consisting of synonyms or definitions of word senses, and (2) the information gathered from Internet using existing search engines. The method was tested on 120 word senses and a precision of 91% was observed.

Autonomous Robot Localization Using WiFi Fingerprinting
Date: April 14, 2011
Creator: Bunkley, Terrence; Wright, Alex & Namuduri, Kamesh
Description: This paper discusses autonomous robot localization using WiFi fingerprinting. Abstract: We are using widely available 802.11 wireless networks to determine the location of autonomous robots. Before a robot can accomplish a simple task such as moving to a specific coordinate, it must accurately know its current location with-in a certain degree of accuracy. Humans often take their eye sight and spatial awareness for granted. For a robot, the computational difficulty of solving the same problem becomes apparent. Our implementation creates a database of wireless signal strengths of a given area and uses the current signal strength reading within the area to find a weighted signal space distance. The "closest" point in the database should also correlate with the current position of the robot. Given the robots correct location, the authors can successfully navigate around any area with sufficient Wi-Fi coverage.

Avoiding the Calf-Path: Digital Preservation Readiness for Growing Collections and Distributed Preservation Networks
Date: 2009
Creator: Halbert, Martin; Skinner, Katherine & McMillan, Gail
Description: This paper discusses digital preservation readiness for growing collections and distributed preservation networks. Abstract: Over the past six years, the members of the MetaArchive Cooperative have worked to identify a series of best practices for distributed digital preservation readiness. These best practices can benefit ongoing initiatives as well as start-up programs which have not yet established regular procedures and standards for directory structures, metadata, and file naming conventions. The authors document what they term the "calf-path syndrome", the way in which early strides in an organization's digitization work may create a legacy that is detrimental to the preservation readiness of their growing digital collections. The authors share relatively simple principles and guidelines for such programs that can greatly improve the subsequent likelihood of implementing successful distributed digital preservation programs.

Awareness of Aphasia and Aphasia Services in South India: Public Health Implications
Date: April 19, 2012
Creator: Chazhikat, Emlynn & Olness, Gloria
Description: This paper discusses research on aphasia. Abstract: Aphasia is a language disorder resulting from brain damage. People who acquire aphasia need rehabilitation to maximize functional recovery. Assessing public awareness of aphasia is critical for development of and access to aphasia-related services. The current study addresses levels of public awareness of aphasia and access to aphasia-related services in an urban area of the State of Kerala, India, a region with potentially high incidence and prevalence of aphasia. Results of an aphasia-awareness survey of 114 urban Kerala residents suggest poor public awareness of aphasia in the population. Less than 10% of those surveyed met criteria for having basic knowledge of aphasia. Semi-structured interviews of two Kerala-based neurologists support the findings of the survey and further suggest that aphasia-related services in the region may be limited. Findings hold implications for development of aphasia services and improvement of the psychosocial life of people who have aphasia.

BABYLON Parallel Text Builder: Gathering Parallel Texts for Low-Density Languages
Date: May 2008
Creator: Mohler, Michael & Mihalcea, Rada
Description: This paper discusses BABYLON parallel text builder. Abstract: This paper describes BABYLON, a system that attempts to overcome the shortage of parallel texts in low-density languages by supplementing existing parallel texts with texts gathered automatically from the Web. In addition to the identification of entire Web pages, the authors also propose a new feature specifically designed to find parallel text chunks within a single document. Experiments carried out on the Quechua-Spanish language pair show that the system is successful in automatically identifying a significant amount of parallel texts on the Web. Evaluations of a machine translation system trained on this corpus indicate that the Web-gathered parallel texts can supplement manually compiled parallel texts and perform significantly better than the manually compiled texts when tested on other Web-gathered data.

Becoming a Teacher of Mathematics to Elementary Students
Date: April 19, 2012
Creator: Walker, Wynona & Tunks, Jeanne
Description: This paper discusses research on becoming a teacher of mathematics to elementary students. Abstract: This is an auto-ethnography of a pre-service teacher during the first semester of Professional Development School, documenting the journey as a learner and teacher of mathematics for this pre-service teacher. There is no hypothesis for this study, due to the qualitative nature of the research. Narrative data from sixteen weeks of communication about teaching and learning mathematics in the community served as data, which were analyzed for points of change from fear of mathematics to readiness to teach it to young children. Art as metaphor serves as pre and post representations of perception of math learning and teaching, with running narratives between as indicators of change. The findings show that due to research and experience on the Response to Intervention Model, assignments from a University of North Texas math methods course, and experience with tutoring elementary students in the pre-service field, reconciliation between math and the pre-service teacher occurs.

Behavioral Measures of Play
Date: 2008
Creator: Guðmundsdóttir, Kristín & Ala'i-Rosales, Shahla
Description: This paper discusses measuring play. Children with autism frequently display deficits in play skills, such as pretend play and object manipulation. This is described both in the diagnostic criteria for autism (American Psychiatric Association, 1994) and in descriptive studies on children's play (Jarrold, 2003; Williams, 2003). However, the nature of these deficits and the degree to which the play of children with autism differs in complexity and variety from the play of typically developing children is unclear (Vig, 2007). The purpose of this article is to review the importance of play in a young child's life and to discuss the importance of measuring play when designing interventions for children with autism. Furthermore, this paper will present an example of a consistent and reliable observation system that assesses the complexity and variety of play on children with autism and with typically developing children.

Between Identity and Commodity: Female Urban Experience in Vicki Baum's 'Menschen im Hotel'
Date: April 19, 2012
Creator: Jones, Carina & Weber, Christoph
Description: Abstract: This paper discusses research on the urban experience of German women in the late Weimar Republic as portrayed in the character Flämmchen in Vicki Baum's 1929 novel 'Menschen im Hotel'. During the Weimar Republic from 1918 to 1933, Germany's large cities appeared to offer women financial and professional independence outside traditional gender roles. To examine how Baum portrays women's pursuit of success and autonomy in the city, this paper analyzes the text according to feminist theory. Flämmchen faces sexual discrimination that limits her ability to live and define herself independently, and she struggles with the sexualized, objectifying image of women present in modern urban society, which represents the female body as a commodity. While 'Menschen in Hotel' breaks from tradition by challenging bourgeois social values, Flämmchen fails to completely break free from traditional definitions of women's roles, reflecting women's disillusionment with the difficult pursuit of emancipation.
