Abstract
Computer-based techniques for grouping documents are described herein. Documents may be grouped, organized, named, and/or indexed by their document character features. Document character features may comprise character counts, character difference counts, missing character counts, and any combination thereof. The comparison of documents may use a comparison threshold value for grouping documents. Documents may be processed in any language.
Claims20
A computer-implemented system for grouping documents, the system comprising:
- a non-transitory document storage system comprising computer memory configured to store a plurality of documents, wherein each document of the plurality of documents comprises distinct character types;
- a computerized matching unit comprising one or more hardware processors,
- wherein the computerized matching unit is configured to access the non-transitory document storage system and generate:
- a first indicator of a common character count between a first document of the plurality of documents and a second document of the plurality of documents, wherein the common character count corresponds to a number of distinct character type occurrences in both the first document and the second document;
- a second indicator of a character variance count between the first document and the second document, wherein the character variance count corresponds to differences in a number of occurrences of distinct character types in both the first document and the second document;
- a third indicator of a missing character count between the first document and the second document, wherein the missing character count corresponds to a number of distinct character type occurrences in the first document and not in the second document;
- a single indicator by combining at least the first indicator, the second indicator, and the third indicator, wherein the computerized matching unit is configured to compare the single indicator to a threshold indicator to determine whether there is a match between the first document and the second document;
- and
- a grouping based at least in part on the single indicator;
- and
- a matching reporting unit configured to report the grouping generated by the computerized matching unit to a user.
8 more elements
A system for grouping documents, the system comprising:
- one or more computing devices comprising one or more hardware processors, programmed, via executable code instructions, to implement:
- a matching unit for comparing a plurality of documents, the matching unit configured to receive as input a first document and a second document, wherein each document of the plurality of documents comprises distinct character types, and
- wherein the matching unit is further configured to generate:
- a first indicator of a common character count between the first document and the second document, wherein the common character count corresponds to a number of distinct character type occurrences in both the first document and the second document;
- a second indicator of a character variance count between the first document and the second document, wherein the character variance count corresponds to differences in a number of occurrences of distinct character types in both the first document and the second document;
- a single indicator by combining at least the first indicator and the second indicator, wherein the matching unit is configured to compare the single indicator to a threshold indicator to determine whether there is a match between the first document and the second document;
- and
- a grouping based at least in part on the single indicator;
- and
- a matching reporting unit adapted to report the grouping generated by the matching unit.
7 more elements
Non-transitory computer storage comprising instructions for causing a computer system to group documents by a process that comprises:
- receiving a first document and a second document, wherein each of the first document and the second document comprises distinct character types;
- generating a first indicator of a common character count between the first document and the second document, wherein the common character count corresponds to a number of distinct character type occurrences in both the first document and the second document;
- generating a second indicator of a character variance count between the first document and the second document, wherein the character variance count corresponds to differences in a number of occurrences of distinct character types in both the first document and the second document;
- generating a third indicator of a missing character count between the first document and the second document, wherein the missing character count corresponds to a number of distinct character type occurrences in the first document and not in the second document;
- generating a single indicator by combining at least the first indicator, the second indicator, and the third indicator;
- comparing the single indicator to a threshold indicator to determine whether there is a match between the first document and the second document;
- and
- transmitting matching information indicative of the comparison of the single indicator to the threshold indicator over a network to a computing device.
