Abstract

A user interface for a full-text document retrieval computerized system comprises a display with a words window in which each query word is displayed by means of a distinctive representation uniquely associated with each displayed word. In a subsequent results window, each document header or title or representation is accompanied by an indicator which employs the same distinctive representation to directly indicate to the user the relative contributions of the individual query words to each listed document. In a preferred embodiment, the distinctive representation is integrated with an associated weight first indicator in a words window, and in the results window the distinctive representations are also integrated with an associated weight second indicator. The distinctive representation can take several forms, such as by a different color or by means of hatching or shading or by displayed icons.

Claims

1. A text retrieval system comprising:

memory means for storing a data base including text items;

means for accepting a user query;

processing means for organizing and querying the data base using at least one key word received in the user query, the processing means producing query results in a format, the format including a list of identified items, the identified items all containing at least one respective one of the at least one key word, the list including a respective indicator associated with each identified item, the respective indicator indicating the importance in the associated identified item of the at least one respective one of the at least one key word; and

display means for displaying the query results in the format.

2. The system of claim 1 wherein each respective indicator is displayed in a respective region of the display means, which respective region has at least one sub-region assigned to a relevant one of the at least one key word.

3. The system of claim 2 wherein a respective size of each of the at least one sub-region indicates a frequency in the associated item of the relevant one of the at least one key word.

4. The system of claim 2 wherein each of the at least one key word is assigned a respective color marking and each sub-region is designated by the respective color marking assigned to the relevant one of the at least one key word.

5. The system of claim 2 wherein each region is rectangular and each sub-region is also rectangular.

6. The system of claim 2 wherein the list comprises a first column that includes the respective regions and a second column that includes respective titles for each identified item, the first and second columns being arranged so that the respective region and title for a given identified item are in a respective row assigned to the given identified item.

7. The system of claim 1 wherein the items are full text documents.

8. The system of claim 1 wherein the items are abstracted documents.

9. The system of claim 1 wherein importance is determined by how many times each of the at least one keyword appears in each of the items.

10. The system of claim 1 wherein the processor generates first, second and third windows for display on the display means, the first window being for input of a user query, the second window being for communicating to the user what aspects of indicators have been assigned to what key words, and the third window being for displaying the format.

11. The system of claim 1 wherein

each respective indicator is a respective region of the display means having at least one sub-region assigned to a relevant one of the at least one key word;

each of the at least one key word is assigned a respective color marking;

a respective size of each of the at least one sub-region indicates the frequency of the relevant one of the at least one key word in the associated item; and

each sub-region is designated by the respective color marking assigned to the relevant one of the at least one key word.

12. The system of claim 1 further comprising retrieval and formatting software for running on the processor and thus achieving the listed processor functions.
