Definitions
- This invention relates generally to a system and method for processing a

- databases needs a system for analyzing and processing the data in order to retrieve the
- the classification system may be known as a
- taxonomy which consists of one or more subject matter headings with sub-headings
- the typical classification may permit the user to select only a broad
- pieces of textual data stored in the database may be used to automatically generate a
- taxonomy for the database.
- the generated taxonomy is unique to the particular
- taxonomy has more detail than a typical classification system. Thus, a search through
- the taxonomy may reduce the number of documents which the user must review.
- taxonomy generation system may automatically generate a taxonomy for
- the topical library may be of the same broad
- documents within the database may be clustered and mapped to form maps illustrating
- leaders which are connected to the most other phrases in the map, known as leaders, may be used to form the first level of the taxonomy underneath the topical index.
- the taxonomy generated reflects the actual phrases contained in the database
- a database including a database having a plurality of pieces of text and a
- a leader phrase from the phrases in the database is
- leader phrase is associated with a predetermined number of other
- a first level of a taxonomy is generated based on the

- the invention is particularly applicable to a system for generating a taxonomy
- Figure 1 is a block diagram of a text processing system 10. The text processing
- system 10 may include a parser 12, a clusterizer 14, a map generator 16, a database
- DB taxonomy generator
- CPU central processing unit
- the clusterizer, the map generator, and the taxonomy generator may all be separate
- the text processing system may receive one or
- more pieces of text such as stories, press releases or documents, and may generate a
- searchable taxonomy which may be searched by one or more client computers (Client #1, Client #2 and Client #N). To generate the searchable taxonomy, each piece of text
- parser 12 which processes each piece of incoming text
- the key phrases may be stored in the database 18. Once the key phrases are extracted from each piece of text, the clusterizer 14 may generate one or more clusters
- the map generator 16 may use the
- clusters in the database in order to generate a graphical map showing the relationships of the key phrases within the various pieces of text to each other so that a user of the system may easily search through the database of pieces of text by viewing the key phrases of the pieces of text.
- the clusters may also be used to generate the
- the database 18 may also store a topical library, as described below
- processing system may be implemented in a variety of manners including a
- a public computer network such as the Internet.
- a client computer may access the text processing system 10 via a
- processing system may generate a user interface showing the top level of the taxonomy
- the taxonomy and another level of the taxonomy will be provided to the user. As some
- the user interface will also provide the user with the ability to look at documents
- FIG. 2 is a block diagram of the taxonomy generator 20 in accordance with
- the taxonomy generator 20 may include a taxonomy creator 30, a combiner 32 and the database 18 from the text processing system.
- the taxonomy may include a taxonomy creator 30, a combiner 32 and the database 18 from the text processing system.
- generator 20 may receive the extracted phrases from the parser, the clusters from the
- the topical library may be a high level
- the extracted phrases and the clusters may be input to the taxonomy creator 30 which
- taxonomy from the taxonomy creator is output to the combiner 32 which then
- taxonomy may be searched by a user accessing the text processing system. Since the
- taxonomy reflects the documents in the database more accurately than a typical

- the method begins at step 42 in which the clusters
- leader clusters are phrases in a map, as described below, which have associations (as
- leader clusters tend to be broader phrases than the less connected other clusters so that the leader clusters
- leader clusters form the best broad subject matter classifiers for the documents in the
- the leader clusters may then be used to form the first level of the taxonomy
- leader phrases are arranged in a hierarchical outline format
- the taxonomy is generated from these clusters in step 48.
- leader phrase related to each leader phrase are arranged underneath the leader phrase in a hierarchical
- taxonomy based on the complexity and depth of the map. If there are more clusters,
- the method returns to step 48 and generates the next level of the taxonomy. If there are problems
- the taxonomy generated is combined with a topical library
- step 52 to generate a final taxonomy in accordance with the invention.
