APPARATUS AND METHOD FOR RETRIEVAL OF DOCUMENTS
A system for support and management of search for documents is presented. The system includes a knowledge-database, query interface and communication to a database of documents to be searched. Information generated during a search session is collected by the system and is added to the knowledge-database. The information is ranked automatically according to the usage of that information by the user. During successive search session or during a search made by another user, the system uses the knowledge database to support the users with keywords, queries and reference documents.
1 . A method for sorting references to documents for display, the method comprising:
storing, in a system database, search queries previously submitted by users of a search system, each search query associated with one or more documents;
receiving, from a client device, a first query including a first keyword;
retrieving, from the system database, one or more stored queries containing the first keyword;
ranking the retrieved queries based on:
a number of keywords in the stored queries that are also in the first query; and
a history of user interaction with documents associated with the stored queries; and
sending for display on the client device the ranked queries and summaries of documents associated with the ranked queries.
2 . The method of claim 1 , further comprising:
generating a list of terms related to the first keyword, the related terms extracted from one or more stored queries;
ranking the related terms based on a number of times each term appears in all system search queries; and
sending for display on the client device the ranked list of related terms.
3 . The method of claim 2 , further comprising:
receiving, from the client device, a second query, the second query including one or more related terms;
receiving user selection of one or more Boolean relations;
retrieving, from the system database, one or more documents associated with the second query; and
sending for display on the client device summaries of the retrieved documents.
4 . The method of claim 1 , further comprising filtering the documents associated with the ranked queries based on a history of user interaction with the documents.
5 . The method of claim 4 , wherein filtering the documents comprises removing documents previously viewed by a searching user.
6 . The method of claim 4 , wherein filtering the documents comprises removing documents not previously viewed by a searching user.
7 . The method of claim 1 , further comprising filtering the documents associated with the ranked queries based on a date range.
8 . A non-transitory computer-readable storage medium storing computer-executable instructions that, in response to executing, cause a device comprising a processor to perform operations, comprising:
storing, in a system database, search queries previously submitted by users of a search system, each search query associated with one or more documents;
receiving, from a client device, a first query including a first keyword;
retrieving, from the system database, one or more stored queries containing the first keyword;
ranking the retrieved queries based on:
a number of keywords in the stored queries that are also in the first query; and
a history of user interaction with documents associated with the stored queries; and
sending for display on the client device the ranked queries and summaries of documents associated with the ranked queries.
9 . The non-transitory computer-readable storage medium of claim 8 , wherein the operations further comprise:
generating a list of terms related to the first keyword, the related terms extracted from one or more stored queries;
ranking the related terms based on a number of times each term appears in all system search queries; and
sending for display on the client device the ranked list of related terms.
10 . The non-transitory computer-readable storage medium of claim 9 , wherein the operations further comprise:
receiving, from the client device, a second query, the second query including one or more related terms;
receiving user selection of one or more Boolean relations;
retrieving, from the system database, one or more documents associated with the second query; and
sending for display on the client device summaries of the retrieved documents.
11 . The non-transitory computer-readable storage medium of claim 8 , wherein the operations further comprise filtering the documents associated with the ranked queries based on a history of user interaction with the documents.
12 . The non-transitory computer-readable storage medium of claim 11 , wherein filtering the documents comprises removing documents previously viewed by a searching user.
13 . The non-transitory computer-readable storage medium of claim 11 , wherein filtering the documents comprises removing documents not previously viewed by a searching user.
14 . The non-transitory computer-readable storage medium of claim 8 , wherein the operations further comprise filtering the documents associated with the ranked queries based on a date range.
15 . A computer system comprising:
one or more computer processors for executing computer program instructions; and
a non-transitory computer-readable storage medium storing instructions executable by the one or more computer processors to perform steps comprising:
storing, in a system database, search queries previously submitted by users of a search system, each search query associated with one or more documents;
receiving, from a client device, a first query including a first keyword;
retrieving, from the system database, one or more stored queries containing the first keyword;
ranking the retrieved queries based on:
a number of keywords in the stored queries that are also in the first query; and
a history of user interaction with documents associated with the stored queries; and
sending for display on the client device the ranked queries and summaries of documents associated with the ranked queries.
16 . The system of claim 15 , further comprising:
generating a list of terms related to the first keyword, the related terms extracted from one or more stored queries;
ranking the related terms based on a number of times each term appears in all system search queries; and
sending for display on the client device the ranked list of related terms.
17 . The system of claim 16 , further comprising:
receiving, from the client device, a second query, the second query including one or more related terms;
receiving user selection of one or more Boolean relations;
retrieving, from the system database, one or more documents associated with the second query; and
sending for display on the client device summaries of the retrieved documents.
18 . The system of claim 15 , further comprising filtering the documents associated with the ranked queries based on a history of user interaction with the documents.
19 . The system of claim 18 , wherein filtering the documents comprises removing documents previously viewed by a searching user.
20 . The system of claim 18 , wherein filtering the documents comprises removing documents not previously viewed by a searching user.
