Creation of a summary for a plurality of texts

A system comprising:

• a processor;
• and
• a memory storing a program, which, when executed on the processor, summarizes a plurality of texts, the processor configured to perform operations comprising:
• generating a vector space based on a first set of vectors, wherein each vector includes one or more feature scores equal to or greater than a predefined value and determined from a frequency of tokens of the plurality of texts;
• executing non-hierarchical clustering using the vector space to generate a first plurality of clusters;
• generating a second set of vectors including quantities of characters in tokens of first representative texts, wherein each first representative text is a selected text from a corresponding cluster of the first plurality of clusters;
• aligning a dimension of each of the vectors of the second set of vectors and executing hierarchical clustering using the second set of vectors to generate a second plurality of clusters;
• summarizing the plurality of texts by determining a second representative text for each of the clusters included in the second plurality of clusters, wherein each second representative text is a selected text from a corresponding cluster of the second plurality of clusters, and wherein the second representative text for each of the clusters included in the second plurality of clusters forms a summary of the plurality of texts;
• and
• displaying, on a display, a visualization of the second plurality of clusters, the summary of the plurality of texts, and an element for dynamically changing a threshold value applied to the hierarchical clustering that alters a number of clusters in the second plurality of clusters, wherein when the element dynamically changes the threshold value, the visualization is automatically changed to reflect the altered number of clusters in the second plurality of clusters.

A computer program product for summarizing a plurality of texts, the computer program product comprising one or more computer readable storage media collectively having program instructions embodied therewith that are executable by at least one processor to cause the at least one processor to:

• generate a vector space based on a first set of vectors, wherein each vector includes one or more feature scores equal to or greater than a predefined value and determined from a frequency of tokens of the plurality of texts;
• execute non-hierarchical clustering using the vector space to generate a first plurality of clusters;
• generate a second set of vectors including quantities of characters in tokens of first representative texts, wherein each first representative text is a selected text from a corresponding cluster of the first plurality of clusters;
• align a dimension of each of the vectors of the second set of vectors and execute hierarchical clustering using the second set of vectors to generate a second plurality of clusters;
• summarize the plurality of texts by determining a second representative text for each of the clusters included in the second plurality of clusters, wherein each second representative text is a selected text from a corresponding cluster of the second plurality of clusters, and wherein the second representative text for each of the clusters included in the second plurality of clusters forms a summary of the plurality of texts;
• and
• display, on a display, a visualization of the second plurality of clusters, the summary of the plurality of texts, and an element for dynamically changing a threshold value applied to the hierarchical clustering that alters a number of clusters in the second plurality of clusters, wherein when the element dynamically changes the threshold value, the visualization is automatically changed to reflect the altered number of clusters in the second plurality of clusters.
