Abstract

A computer-implemented method of managing perspective data associated with a common feature in items is disclosed. The method can include identifying a common feature in a first item and a second item, the first item having a set of perspective data and establishing a subset of perspective data associated with the common feature. The method can include associating the subset of perspective with the second item. The method can include determining a set of relevancy scores for the subset of perspective data associated with the common feature and establishing a set of relevant perspective data from the subset of perspective data. The set of relevant perspective data can have relevancy scores outside of a relevancy threshold. The method can include associating the set of relevant perspective data with the second item.

Claims

1. A system for managing perspective data associated with a common feature in items, the system comprising:

a natural language processing unit configured to;

identify a common feature in a first item and a second item, the first item having a set of perspective data, the common feature relating a component of the first item with a component of the second item, and wherein the natural language processing unit is further configured to, as part of the identifying;

parse, using a natural language processing technique configured to analyze semantic and syntactic content, a set of description data associated with the first and second items;

determine, in response to parsing the set of description data, a set of shared characteristics in the set of description data; and

select, from the set of shared characteristics, at least one shared characteristic as the common feature;

establish a subset of perspective data associated with the common feature;

determine a set of relevancy scores for the subset of perspective data associated with the common feature; and

establish a set of relevant perspective data from the subset of perspective data, the set of relevant perspective data having relevancy scores outside of a relevancy threshold; and

a logic device configured to;

associate the set of relevant perspective data with the second item.

2. The system of claim 1, wherein:

the natural language processing unit is further configured to;

determine a set of relevancy scores for the subset of perspective data associated with the common feature;

establish a set of relevant perspective data from the subset of perspective data, the set of relevant perspective data having relevancy scores outside of a relevancy threshold; and

wherein the logic device is further configured to;

associate the set of relevant perspective data with the second item.

3. The system of claim 2, wherein:

the natural language processing unit being configured to determine the set of relevancy scores for the subset of perspective data further includes being configured to;

parse, using a natural language processing technique configured to analyze semantic and syntactic content, the subset of perspective data;

calculate, based on syntactic content, semantic content, and metadata for the subset of perspective data, the set of relevancy scores; and

assign the set of relevancy scores to the subset of perspective data.

4. The system of claim 1, wherein:

the natural language processing unit being configured to determine a set of shared characteristics in the set of description data further includes being configured to;

determine, based on semantic information analyzed by the natural language processing technique, that the first item and second item have at least one characteristic which is substantially similar; and

include the at least one characteristic which is substantially similar in the set of shared characteristics.

5. The system of claim 4, wherein:

the natural language processing unit being configured to determine, based on semantic information analyzed by the natural language processing technique, that the first item and second item have at least one characteristic which is substantially similar, includes being configured to;

map a first feature from the first item to a first concept;

map a second feature from the second item to a second concept;

determine whether the first concept and second concept are substantially similar; and

determine that the first item and second item have at least one characteristic which is substantially similar in response to determining that the first concept and second concept are substantially similar.

6. The system of claim 5, wherein:

the natural language processing unit being configured to determine whether the first concept and second concept are substantially similar includes being configured to;

determine whether the first concept and second concept are the same; and

determine that the first concept and second concept are substantially similar in response to determining that the first concept and second concept are the same.

7. A computer program product for managing perspective data associated with a common feature in items, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to perform a method comprising:

identifying a common feature in a first item and a second item, the first item having a set of perspective data, the common feature relating a component of the first item with a component of the second item, and wherein the identifying includes;

parsing, using a natural language processing technique configured to analyze semantic and syntactic content, a set of description data associated with the first and second items;

determining, in response to parsing the set of description data, a set of shared characteristics in the set of description data; and

selecting, from the set of shared characteristics, at least one feature as the common feature;

establishing a subset of perspective data associated with the common feature; and

associating the subset of perspective data with the second item.

8. The computer program product of claim 7, wherein the method further comprises:

determining a set of relevancy scores for the subset of perspective data associated with the common feature;

establishing a set of relevant perspective data from the subset of perspective data, the set of relevant perspective data having relevancy scores outside of a relevancy threshold; and

associating the set of relevant perspective data with the second item.

9. The computer program product of claim 8, wherein:

determining the set of relevancy scores for the subset of perspective data further includes;

parsing, using a natural language processing technique configured to analyze semantic and syntactic content, the subset of perspective data;

calculating, based on syntactic content, semantic content, and metadata for the subset of perspective data, the set of relevancy scores; and

assigning the set of relevancy scores to the subset of perspective data.

10. The computer program product of claim 7, wherein:

determining a set of shared characteristics in the set of description data further includes;

determining, based on semantic information analyzed by the natural language processing technique, that the first item and second item have at least one characteristic which is substantially similar; and

including the at least one characteristic which is substantially similar in the set of shared characteristics.

11. The computer program product of claim 10, wherein:

determining, based on semantic information analyzed by the natural language processing technique, that the first item and second item have at least one characteristic which is substantially similar includes;

mapping a first feature from the first item to a first concept;

mapping a second feature from the second item to a second concept;

determining whether the first concept and second concept are substantially similar; and

determining that the first item and second item have at least one characteristic which is substantially similar in response to determining that the first concept and second concept are substantially similar.
