Computer-implemented system and method for analyzing clusters of coded documents

1. A computer-implemented method for analyzing clusters of coded documents, comprising:

providing a display of clusters of documents, wherein at least a portion of the documents are each associated with a classification code;

displaying a representation of each of the documents associated with each cluster based on one of the associated classification code and an absence of the associated classification code;

receiving a search query comprising one or more search terms and associating each search term with one of the classification codes based on the documents;

identifying those documents that satisfy the search query;

changing the representations of the documents that satisfy the search query based on the classification codes associated with one or more of the search terms,

zooming out of the display of clusters;

changing the display of the documents and the clusters;

determining the changed display, comprising:

counting a number of documents associated with each classification code type;

calculating for each cluster a percentage of the number of documents for each classification code type; and

displaying each cluster as a representation of the percentage of the documents for each classification code type as the changed display; and

selecting from a cluster in the changed display a subset of documents associated with one classification code type;

wherein the change in representation provides one of an indication of agreement between the classification code associated with one such document and the classification codes of the one or more search terms, and an indication of disagreement between the classification code associated with the document and the classification codes of the search terms.

2. A method according to claim 1 , further comprising:

for each type of classification code, generating a list of relevant terms across all the documents;

comparing each search term with the lists; and

assigning to one such search term the classification code of the list with a relevant term matching that search term.

3. A method according to claim 2 , wherein the list of relevant terms for each type of classification code is representative of the documents associated with that classification code type.

4. A method according to claim 1 , further comprising:

determining when to change the display, comprising:

setting a threshold value for a size of the display;

determining whether the size of the display based on the zooming out exceeds the threshold; and

providing the changed display when the size of the display exceeds the threshold.

5. A method according to claim 1 , wherein the representation of each cluster comprises a pie chart based on the percentage of documents for each classification code type.

6. A method according to claim 1 , further comprising:

dividing the display of clusters, comprising:

prioritizing the documents;

ordering the documents based on the prioritization;

dividing the ordered documents into bins; and

separately displaying the documents associated with each bin.

7. A method according to claim 1 , further comprising:

for each document that satisfies the search query, assigning the classification code of one or more of the search terms included in or associated with that document.

8. A method according to claim 1 , further comprising:

changing a representation of one or more of the clusters in the display based on a relevance of that cluster to the search terms.
