Artificial intelligence and machine learning

Data mining, or knowledge discovery in databases, is the nontrivial extraction of implicit, previously unknown and potentially useful information from data. Statistical methods are used that enable trends and other relationships to be identified in large databases. The major reason that data mining has attracted attention is due to the wide

Querying Knowledge Graphs by Example Entity Tuples

GQBEruns queries on knowledge data graphs. A datagraph is a directed multi-graph G with node set V(G) and edge set E(G). Each node v∈V(G)represents an entity and has a unique identifier id(v). 2 Each edge e=(v i,v j)∈E(G)denotes a directed relationship from entity v i to entity v j. It has a label, denoted as label(e). Multiple edges can ...

Data modeling It’s much easier to model product catalogs with a NoSQL document database because all data for a single product can be stored together in a single document instead of multiple rows, often in multiple tables. And not only is it easier to model the data, it’s simpler and faster to access – there’s no need to perform a query with
