News clipping method and system

A news clipping method comprising:

• a step of registering delivery condition expressions including text delivery conditions which a plurality of users or system operators specified for text data;
• a text retrieval step of deciding if said plurality of query expressions are satisfied in said text data by once scanning said text data;
• and
• a step of distributing said text data to the user whose query expression is found to be satisfied by said text retrieval step, when said delivery condition registered by said delivery condition registering step is satisfied.

A news clipping method comprising:

• a query expression analyzing step of extracting all the query terms from query expressions specified by a plurality of users;
• a step of generating a query term number count table which stores management information including said users and the number of all said query terms extracted from said query expressions of said users;
• a step of generating a multiple strings matching table to which reference is made when text data is once scanned so that the corresponding terms occurring during the scanning can be matched with all said query terms extracted from said query expressions;
• a step of generating a user list having identifiers of said users who specified said query expressions, in association with said query terms extracted from said query expressions, so that said terms and said identifiers are connected as a list in association with each other;
• and
• a query expression management table eliminating step of eliminating information associated with elimination-indicated ones of said query expressions from said query term number count table and said user list.

A news clipping system comprising:

• query expression analyzing means for extracting all query terms from query expressions specified by a plurality of users;
• means for generating a query term number count table which has stored therein management information including said users and the number of all said query terms extracted from said query expressions of said users;
• means for generating a multiple strings matching table to which reference is made when text data is once scanned so that the corresponding terms occurring during the scanning can be matched with all the query terms extracted from said query expressions;
• means for generating a user list having identifiers of said users who specified said query expressions in association with said query terms extracted from said query expressions, said user identifiers and said query terms being connected as a list in association with each other;
• means for scanning said text data with reference to said multiple strings matching table to match the corresponding terms occurring during the scanning with all said query terms extracted by said query expression analyzing means when decision is made of whether or not said query expressions are satisfied in said text data;
• and
• means for deciding if said query expressions are satisfied in said text data by referring to said query terms matched by said text scanning means, said user list and said query term number count table.

A news clipping system comprising:

• means for registering delivery condition expressions including delivery conditions specified for text delivery by a plurality of users or system operators;
• text search means for deciding if said plurality of query expressions are satisfied in said text data by scanning only once said text data;
• text delivery control means for distributing said text data to the user whose query expression is satisfied by said text search means when the corresponding one of said delivery conditions registered by said delivery condition expression registering means is satisfied;
• delivery condition expression analyzing means for extracting the identifiers of said users who need to specify delivery conditions, and said delivery conditions from said delivery condition expressions;
• and
• means for generating a delivery condition management table which has stored therein said user identifiers and said delivery conditions extracted from said delivery condition expressions by said delivery condition analyzing means, said text delivery control means comprising:
• means for deciding if said delivery conditions are satisfied with reference to said delivery condition management table;
• and
• text delivery means for distributing said text data to the corresponding user when said delivery condition is decided to be satisfied by said delivery condition deciding means.

A news clipping system comprising:

• means for registering query expressions specified by a plurality of users;
• query expression analyzing means for extracting all query terms from said query expressions;
• means for generating a query term number count table which has stored therein management information including said users and the number of all query terms extracted from said query expressions of said users;
• means for generating a multiple string matching table to which reference is made when the terms occurring in text data are matched with all the query terms extracted from said query expressions by scanning only once said text data;
• means for generating a user list having the identifiers of said users who specified said query expressions in association with the query terms extracted from said query expressions, said identifiers and said query terms being connected as a list in association with each other;
• and
• query expression management table eliminating means for eliminating information associated with the elimination-indicated query expressions from said query term number count table and said user list.

A recording medium having stored therein clipping programs which can be read by a computer and used for a news clipping system into which query terms and text data are inputted comprising:

• a query term number count table having the number of query terms included for each user in each of a plurality of query expressions of users;
• a user list having said users which specified said plurality of query terms;
• a term occurrence count table having the occurrence count of different terms found for each user in said text data;
• and
• a list of users associated with the coincidence between the query term number of said query term number count table and the occurrence count of said term occurrence count table.
