Abstract
A data analyzer apparatus comprises a document storage device storing a set of documents containing attributes representing text data and time data, a key concept dictionary storage device storing a key concept dictionary, a selector selecting a subset of documents from the set of documents in accordance with a given combination of the attributes, a first extraction device extracting a set of key concepts from each document belonging to the subset selected, based on the key concept dictionary, a second extraction device extracting the time data from each document belonging to the subset selected, and a concept sequence generator generating concept sequence including key concepts extracted from each document belonging to the subset using the time data.
Claims21
A data analyzer apparatus comprising:
- a document storage device configured to store a set of documents containing plural attributes representing at least text data and time data;
- a key concept dictionary storage device configured to store a key concept dictionary including representative words or phrases that are likely to be described in the text data;
- a selector configured to select a subset including plural documents associated with each other from the set of documents stored in the document storage device in accordance with a given combination of the attributes;
- a first extraction device configured to extract a set of key concepts from each of plural documents belonging to the subset selected, based on the key concept dictionary;
- a second extraction device configured to extract the time data from each of the plural documents belonging to the subset selected;
- and
- a concept sequence generator configured to generate concept sequence including key concepts extracted from each of the documents belonging to the subset using the time data included in each of the documents.
A data analyzer apparatus comprising:
- means for storing a set of documents containing plural attributes representing at least text data and time data and a key concept dictionary including representative words or phrases that are likely to be described in the text data;
- means for selecting a subset including plural documents associated with each other from the set of documents stored in the storing means in accordance with a given combination of the attributes;
- means for extracting a set of key concepts from each of plural documents belonging to the subset selected, based on the key concept dictionary, and extracting the time data from each of the plural documents belonging to the subset selected;
- and
- means for generating concept sequence including key concepts extracted from each of the documents belonging to the subset using the time data included in each of the documents.
A data analysis method comprising:
- storing a set of documents containing plural attributes representing at least text data and time data in a document storage device;
- storing a key concept dictionary including representative words or phrases that are likely to be described in the text data in a key concept dictionary storage device;
- selecting a subset including plural documents associated with each other from the set of documents stored in the document storage device in accordance with a given combination of the attributes;
- extracting a set of key concepts from each of plural documents belonging to the subset selected, based on the key concept dictionary;
- extracting the time data from each of the plural documents belonging to the subset selected;
- and
- generating concept sequence including key concepts extracted from each of the documents belonging to the subset using the time data included in each of the documents.
A data analysis program stored in a computer readable medium, the program including:
- means for instructing a computer to store a set of documents containing plural attributes representing at least text data and time data in a document storage device;
- means for instructing the computer to store a key concept dictionary including representative words or phrases that are likely to be described in the text data in a key concept dictionary storage device;
- means for instructing the computer to select a subset including plural documents associated with each other from the set of documents stored in the document storage device in accordance with a given combination of the attributes;
- means for instructing the computer to extract a set of key concepts from each of plural documents belonging to the subset selected, based on the key concept dictionary;
- means for instructing the computer to extract the time data from each of the plural documents belonging to the subset selected;
- and
- means for instructing the computer to generate concept sequence including key concepts extracted from each of the documents belonging to the subset using the time data included in each of the documents.
