Abstract

A computerized data retrieval system, especially for commodity price information databases, having a windowing system which aids a user in creating and revising formal search language queries, a database searching engine responsive to such queries, means to generate and format results in both textual and graphic reports, and a capacity for echoing a formal search language query to a display in a near-natural language format for easy comprehension by the user as the query is constructed using the windowing system. The system has facilities for including domain knowledge in a query, such as market knowledge of calendar events, national holidays, triple-witching hours, and option contract expiration dates. The system has additional facilities that permit a user to include more fundamental domain knowledge, such as dates of political elections, date of issuance and value of company earning reports, the consumer price index, and so on. The near-natural language format of the query may be created and revised either through the windowing system or with a text editor.

Claims

1. A computerized data retrieval system comprising:

a data base containing information defining the fluctuation of commodity prices over time in combination with additional information designating the date of occurrence of events;

a windowing user search request creation and revision system embodying a formal search language that permits the definition of search requests in their entirety by means of windowing templates, that includes a facility for ANDing and ORing search request portions together, and that includes a facility for limiting any search request to commodity price information dated proximate in time to at least one said designated event;

search execution means for performing search requests formulated through the use of said windowing system;

report generation means for generating reports presenting the results of searches executed by said search execution means; and

echo means connected to receive search request defining information from said windowing system for echoing a search request formulated with said windowing system to the user in the form of a near-natural-language search request while the user is formulating said search request using said windowing system.

2. A system in accordance with claim 1 which includes means for generating at least three distinct regions visible to a user on a display screen, including one region in which a near-natural language view of a search request appears, a second window in which user-selectable command options appears, and a third region in which user search query formulation templates appear.

3. A system in accordance with claim 2 wherein the sequence of said formulation templates are pre-defined based upon previous selection of said command options.

4. A system in accordance with claim 2 wherein each said formulation template is contingent upon the appropriate response of the user to a previous said template.

5. A system in accordance with claim 1 to which is added near-natural-language search request user editing means for entering and/or revising near-natural-language search requests, to which is added reverse echo means connected to send search request defining information to said windowing system for sending a search request formulated and/or revised with said user editing means back to a said windowing system, and in which said search execution means can perform search requests formulated through use of said user editing means as well as through use of said windowing system.

6. A system in accordance with claims 1 wherein the market knowledge comprises calendar events such as the days of the week, the beginning of months, quarters, and years, and the like and in which the search language and windowing system are designed to facilitate use of such events in search requests.

7. A system in accordance with claims 1 wherein the market knowledge comprises calendar events such as national holidays and the like and in which the search language and windowing system are designed to facilitate use of such events in search requests.

8. A system in accordance with claim 1 wherein the market knowledge information comprises market-relevant events such as triple-witching hours and option contract expiration dates and in which the search language and windowing system are designed to facilitate use of such events in search requests.

9. A system in accordance with claim 1 wherein the market knowledge information includes periodically occurring event information and an associated value with each such event, such as the date of issuance and the value of company earning reports, of the consumer price index, and the like, and wherein said formal search language and windowing system are designed to facilitate use of such events in search requests and also to facilitate limiting the retrieved information in some manner by the event'"'"'s associated value.

10. A system in accordance with claim 1 wherein the market knowledge information includes values that fluctuate daily and wherein said formal search language and windowing system are designed to facilitate use of such values to limit in some manner the amount of information that is retrieved.

11. A system in accordance with claim 1, wherein the windowing user search request creation and revision system permits the user to choose from and customize seven general query formats with user-defined conditions, said formats including:

a first format which displays commodity price information satisfying said conditions,

a second format which displays a count of occurrences satisfying said conditions,

a third format which displays a percentage of occurrences satisfying said conditions within a larger set of occurrences satisfying a second set of conditions,

a fourth format which displays a chronologically first user-selected number of commodity price information values satisfying said conditions,

a fifth format which displays a chronologically last user-selected number of commodity price information values satisfying said conditions,

a sixth format which displays a user-selected number of largest commodity price information values satisfying said conditions, and

a seventh format which displays a user-selected number of least commodity price information values satisfying said conditions.

12. A system in accordance with claim 1, wherein the windowing user search request creation and revision system permits the user to choose from and customize three general condition formats, said formats including:

a first format conditioning commodity price information with date-related limitations,

a second format conditioning commodity price information with a comparison between a first set of commodity price information and a second set of commodity price information, and

a third format conditioning commodity price information with a percentage change criterion in a third set of commodity price information.

13. A method for assisting a user in formulating a search request preparatory to retrieving information from a data base containing multiple sets of information values, with each set containing multiple values corresponding to different times and/or dates, and also containing at least one other set of information defining the dates of occurrence of events, comprising the steps of:

displaying a series of templates to the user to guide the user through the process of formulating an information retrieval search request;

accepting from the user information defining selections made by the user when presented with said templates;

using said selection-defining information provided by the user as a guide, formulating and displaying to the user near-natural-language search requests accurately stating the search the user has formulated so far;

displaying templates to the user that permit the user to combine multiple search request portions using AND and/or OR logical operators;

displaying templates to the user that permit a portion of any search request to be qualified to retrieve information dated proximate to at least one of said events; and

when a search request is completely formulated, converting it into a form suitable for presentation to a search execution engine.

14. A method in accordance with claim 13 to which is added the steps of accepting from the user information defining revisions to be made to said near-natural-language search request, revising said near-natural-language search request accordingly, redisplaying said near-natural-language search request to the user, and adjusting said series of templates so that their organization and contents matches the revised near-natural-language search request.
