1. Text Curation for Clustering of Free-text Survey Responses
Master-uppsats, Linköpings universitet/Institutionen för datavetenskapSammanfattning : When issuing surveys, having the option for free-text answer fields is only feasible where the number of respondents is small, as the work to summarize the answers becomes unmanageable with a large number of responses. Using NLP techniques to cluster these answers and summarize them would allow a greater range of survey creators to incorporate free-text answers in their survey, without making their workload too large.

4. Evaluation of clusterings of gene expression data
Magister-uppsats, Institutionen för datavetenskapSammanfattning : Recent literature has investigated the use of different clustering techniques for analysis of gene expression data. For example, self-organizing maps (SOMs) have been used to identify gene clusters of clear biological relevance in human hematopoietic differentiation and the yeast cell cycle (Tamayo et al., 1999).
