   Sammanfattning : 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.

3. 2. Clustering of Financial Account Time Series Using Self Organizing Maps

   Master-uppsats, KTH/Matematisk statistik

   Nyckelord :Kohonen; financial accounts; self organizing maps; clustring; time series; Kohonen; finansiella konton; klustring; tidsserier;

   Sammanfattning : This thesis aims to cluster financial account time series by extracting global features from the time series and by using two different dimensionality reduction methods, Kohonen Self Organizing Maps and principal component analysis, to cluster the set of the time series by using K-means. The results are then used to further cluster a set of financial services provided by a financial institution, to determine if it is possible to find a set of services which coincide with the time series clusters.
