  1. 1. Text Curation for Clustering of Free-text Survey Responses

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Anton Gefvert; [2023]
    Nyckelord :Natural Language Processing; NLP; Sentence Representations; Sentence Representation Models; Survey; Surveys; Clustring;

    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.

  2. 2. Exploring Short Text Clustering for Transactional Data

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Staffan Annerwall; [2021]
    Nyckelord :short text; clustering; classification; transactional data;

    Sammanfattning : The digital revolution has led to an increase in digitization of transactional information. Due to the large amount of data, the transactions must be categorized such that an overview of spending can be obtained. LÄS MER

  3. 3. Clustering biological data using a hybrid approach : Composition of clusterings from different features

    Magister-uppsats, Institutionen för kommunikation och information

    Författare :Jens Keller; [2008]
    Nyckelord :clustering; bioinformatics; hybrid;

    Sammanfattning : Clustering of data is a well-researched topic in computer sciences. Many approaches have been designed for different tasks. In biology many of these approaches are hierarchical and the result is usually represented in dendrograms, e.g. LÄS MER

  4. 4. Evaluation of clusterings of gene expression data

    Magister-uppsats, Institutionen för datavetenskap

    Författare :Zelmina Lubovac; [2000]
    Nyckelord :Gene expression analysis; Evaluation of clusterings; Self organizing maps; Average linkage clustering; Annotations;

    Sammanfattning : 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).
