Multiple rule development support for text analytics

A system for applying text analytics rules to a corpus of documents, the system comprising a processor configured with logic to:

• facilitate selection of a document from the corpus of documents within a graphical user interface (GUI), wherein the selected document is opened to display text of the selected document within the GUI and to further display a token parse tree that lists tokens corresponding to text components of the document, wherein each token identifies an individual word, one or more numbers, or a punctuation mark and wherein each token is individually selectable via the GUI;
• facilitate construction of a text analytics rule, via interaction with the GUI, by user selection of at least one token and at least one corresponding token component from the token parse tree;
• in response to a user selecting the at least one token and the at least one corresponding token component from the token parse tree to facilitate construction of the text analytics rule, apply the constructed text analytics rule to the corpus of documents and provide a list of matching documents or hits via the GUI, the list of matching documents or hits including a listing of matching text components from the corpus of documents that are associated with tokens that comply with the constructed text analytics rule, the listing of matching text components including, on each line, the identified text component that matches or complies with the text analytics rule as well as preceding text components and post text components in relation to the matching text component;
• and
• present text of the selected document within a first window of the GUI, the token parse tree for the selected document in a second window of the GUI, and the list of matching documents or hits in a third window of the GUI so as to facilitate visualization of information within the first, second and third windows simultaneously within a single display, none of the displayed windows obstructing a view of any other window of the displayed windows
• wherein a change by user selection of at least one other token and at least one other corresponding token component from the token parse tree for the selected document results in the construction of a different text analytics rule and also a modified list of matching documents or hits via the GUI.

A computer program product for applying text analytics rules to a corpus of documents, the computer program product comprising:

• a computer readable storage device comprising hardware having computer readable program code embodied therewith, the computer readable program code configured to:
• facilitate selection of a document from the corpus of documents within a graphical user interface (GUI), wherein the selected document is opened to display text of the selected document within the GUI and to further display a token parse tree that lists tokens corresponding to text components of the document, wherein each token identifies an individual word, one or more numbers, or a punctuation mark and wherein each token is individually selectable via the GUI;
• facilitate construction of a text analytics rule, utilizing the GUI, by user selection of at least one token and at least one corresponding token component from the token parse tree;
• in response to a user selecting the at least one token and the at least one corresponding token component from the token parse tree to facilitate construction of the text analytics rule, apply the constructed text analytics rule to the corpus of documents and provide a list of matching documents or hits via the GUI, the list of matching documents or hits including a listing of matching text components from the corpus of documents that are associated with tokens that comply with the constructed text analytics rule, the listing of matching text components including, on each line, the identified text component that matches or complies with the text analytics rule as well as preceding text components and post text components in relation to the matching text component;
• and
• present text of the selected document for display within a first window of the GUI, present the token parse tree for the selected document for display in a second window of the GUI, and present the list of matching documents or hits for display in a third window of the GUI so as to facilitate visualization of information within the first, second and third windows simultaneously within a single display, none of the displayed windows obstructing a view of any other window of the displayed windows;
• wherein a change by user selection of at least one other token and at least one other corresponding token component from the token parse tree for the selected document results in the construction of a different text analytics rule and also a modified list of matching documents or hits via the GUI.
