Rather than simply applying a static approach of matching a first attribute in the first dataset with a first attribute in the second dataset, etc., an importance of a particular attribute can be identified to assist in accurate matching versus another attribute that does not have as much importance in the matching process. For example, a DESCRIPTION attribute can have greater importance than a DATATYPE attribute, e.g., as a function of the number of terms available to be matched in a DESCRIPTION than in a DATATYPE field. By identifying the degree of matching of an important attribute, the matched values of lesser important parameters can be dynamically adjusted based on the degree of matching of the important attribute. Such an approach enables vast amounts of datasets to be automatically matched. ## Claims ### Claim 1 A system comprising: a memory that stores computer executable components; and a processor that executes at least one of the computer executable components that: determines, from a group of vehicle signal datasets, a degree of matching between a first vehicle signal dataset of a first vehicle from the group of vehicle signal datasets and a second vehicle signal dataset of a second vehicle from the group of vehicle signal datasets, wherein the first vehicle signal dataset is in a first format, wherein the second vehicle signal dataset is in a second format that is different from the first format, wherein the degree of matching is based on a similarity of two or more attributes in the first vehicle signal dataset with two or more attributes in the second vehicle signal dataset, wherein the two or more attributes in the first vehicle signal dataset are known, and wherein the determining the degree of matching comprises: identifying, in the two or more attributes in the first vehicle signal dataset, a first attribute having a most importance that is indicative of high confidence in the determination of degree of matching and a second attribute having a least importance that is indicative of a low confidence in the determination of the degree of matching, determining a first degree of similarity between a first attribute in the second vehicle signal dataset with the first attribute in the first vehicle signal dataset, determining a second degree of similarity between a second attribute in the second vehicle signal dataset with the second attribute in the first vehicle signal dataset, and applying the second degree of similarity to the first degree of similarity to dynamically adjust the first degree of similarity as a function of the second degree of similarity;
